    Sex Differences in Treatments, Relative Survival, and Excess Mortality Following Acute Myocardial Infarction: National Cohort Study Using the SWEDEHEART Registry2017In: Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, ISSN 2047-9980, E-ISSN 2047-9980, Vol. 6, no 12, article id e007123Article in journal (Refereed)
    Abstract [en]

    Background-This study assessed sex differences in treatments, all-cause mortality, relative survival, and excess mortality following acute myocardial infarction. Methods and Results-A population-based cohort of all hospitals providing acute myocardial infarction care in Sweden (SWEDEHEART [Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies]) from 2003 to 2013 was included in the analysis. Excess mortality rate ratios (EMRRs), adjusted for clinical characteristics and guideline-indicated treatments after matching by age, sex, and year to background mortality data, were estimated. Although there were no sex differences in all-cause mortality adjusted for age, year of hospitalization, and comorbidities for ST-segment-elevation myocardial infarction (STEMI) and non-STEMI at 1 year (mortality rate ratio: 1.01 [95% confidence interval (CI), 0.96-1.05] and 0.97 [95% CI, 0.95-.99], respectively) and 5 years (mortality rate ratio: 1.03 [95% CI, 0.99-1.07] and 0.97 [95% CI, 0.95-.99], respectively), excess mortality was higher among women compared with men for STEMI and non-STEMI at 1 year (EMRR: 1.89 [95% CI, 1.66-2.16] and 1.20 [95% CI, 1.16-1.24], respectively) and 5 years (EMRR: 1.60 [95% CI, 1.48-1.72] and 1.26 [95% CI, 1.21-1.32], respectively). After further adjustment for the use of guideline-indicated treatments, excess mortality among women with non-STEMI was not significant at 1 year (EMRR: 1.01 [95% CI, 0.97-1.04]) and slightly higher at 5 years (EMRR: 1.07 [95% CI, 1.02-1.12]). For STEMI, adjustment for treatments attenuated the excess mortality for women at 1 year (EMRR: 1.43 [95% CI, 1.26-1.62]) and 5 years (EMRR: 1.31 [95% CI, 1.19-1.43]). Conclusions-Women with acute myocardial infarction did not have statistically different all-cause mortality, but had higher excess mortality compared with men that was attenuated after adjustment for the use of guideline-indicated treatments. This suggests that improved adherence to guideline recommendations for the treatment of acute myocardial infarction may reduce premature cardiovascular death among women.

    Although women are less likely to be admitted to coronary care units, they are treated equally to men and have better outcome: A prospective cohort study in patients with non ST-elevation acute coronary syndromes2009In: Acute cardiac care, ISSN 1748-295X, Vol. 11, no 3, p. 173-180Article in journal (Refereed)
    Abstract [en]

    Background: The aim of this study was to assess gender differences in admission level of care, management and outcome in patients with non ST-elevation acute coronary syndromes (NSTE-ACS), initially admitted to either coronary care units (CCU) or general wards. Method: Patients admitted to CCUs were routinely registered in the RIKS-HIA registry. In addition, patients admitted to general wards with suspected ACS were also identified and registered. Multivariable regression analysis was used to adjust for baseline differences between the genders. Results: We included 570 consecutive patients with a discharge diagnosis of NSTE-ACS. Women were less likely to be admitted to coronary care units (56% versus 69%, P=0.002), even after adjustment (odds ratio (OR), 0.65; 95% confidence interval (CI): 0.43-0.98). After adjustment for differences in baseline characteristics, women were treated similarly to men. We found no significant differences in crude short-, or long-term mortality between the genders. However, adjustment for background characteristics revealed lower one-year mortality in women (OR: 0.58; 95% CI: 0.34-0.99). Conclusion: In this study on patients with NSTE-ACS, women were less likely to be admitted to coronary care units. However, the overall treatment was as intensive for women as for men. Moreover, after adjustment, one-year mortality was lower in women.

    Characteristics of patients with acute myocardial infarction contacting primary healthcare before hospitalisation: a cross-sectional study2018In: BMC Family Practice, ISSN 1471-2296, E-ISSN 1471-2296, Vol. 19, article id 167Article in journal (Refereed)
    Abstract [en]

    Background: The characteristics of patients with on-going myocardial infarction (MI) contacting the primary healthcare (PHC) centre before hospitalisation are not well known. Prompt diagnosis is crucial in patients with MI, but many patients delay seeking medical care. The aims of this study was to 1) describe background characteristics, symptoms, actions and delay times in patients contacting the PHC before hospitalisation when falling ill with an acute MI, 2) compare those patients with acute MI patients not contacting the PHC, and 3) explore factors associated with a PHC contact in acute MI patients. Methods: This was a cross-sectional multicentre study, enrolling consecutive patients with MI within 24 hours of admission to hospital from Nov 2012 until Feb 2014. Results: A total of 688 patients with MI, 519 men and 169 women, were included; the mean age was 66 +/- 11 years. One in five people contacted PHC instead of the recommended emergency medical services (EMS), and 94% of these patients experienced cardinal symptoms of an acute MI; i.e., chest pain, and/or radiating pain in the arms, and/or cold sweat. Median delay time from symptom-onset-to-decision-to-seek-care was 2:15 hours in PHC patients and 0:40 hours in non-PHC patients (pamp;lt;0.01). The probability of utilising the PHC before hospitalisation was associated with fluctuating symptoms (OR 1.74), pain intensity (OR 0.90) symptoms during off-hours (OR 0.42), study hospital (OR 3.49 and 2.52, respectively, for two of the county hospitals) and a final STEMI diagnosis (OR 0.58). Conclusions: Ambulance services are still underutilized in acute MI patients. A substantial part of the patients contacts their primary healthcare centre before they are diagnosed with MI, although experiencing cardinal symptoms such as chest pain. There is need for better knowledge in the population about symptoms of MI and adequate pathways to qualified care. Knowledge and awareness amongst primary healthcare professionals on the occurrence of MI patients is imperative.

    Symptoms and delay times during myocardial infarction in 694 patients with and without diabetes; an explorative cross-sectional study2016In: BMC Cardiovascular Disorders, ISSN 1471-2261, E-ISSN 1471-2261, Vol. 16, no 108, article id 108Article in journal (Refereed)
    Abstract [en]

    Background: In myocardial infarction (MI) a short pre-hospital delay, prompt diagnosis and timely reperfusion treatment can improve the prognosis. Despite the importance of timely care seeking, many patients with MI symptoms delay seeking medical care. Previous research is inconclusive about differences in symptom presentation and pre-hospital delay between patients with and without diabetes during MI. The aim of this study was to describe symptoms and patient delay during MI in patients with and without diabetes. Methods: Swedish cross-sectional multicentre survey study enrolling MI patients in 5 centres within 24 h from admittance. Results: Chest pain was common in patients both with and without diabetes and did not differ after adjustment for age and sex. Patients with diabetes had higher risk for shoulder pain/discomfort, shortness of breath, and tiredness, but lower risk for cold sweat. The three most common symptoms reported by patients with diabetes were chest pain, pain in arms/hands and tiredness. In patients without diabetes the most common symptoms were chest pain, cold sweat and pain in arms/hands. Median patient delay time was 2 h, 24 min for patients with diabetes and 1 h, 15 min for patients without diabetes (p = 0.024). Conclusion: Chest pain was common both in patients with and without diabetes. There were more similarities than differences in MI symptoms between patients with and without diabetes but patients with diabetes had considerably longer delay. This knowledge is important not only for health care personnel meeting patients with suspected MI, but also for the education of people with diabetes.

    Bleeding complications after myocardial infarction in a real world population - An observational retrospective study with a sex perspective2018In: Thrombosis Research, ISSN 0049-3848, E-ISSN 1879-2472, Vol. 167, p. 156-163Article in journal (Refereed)
    Abstract [en]

    Introduction: The aim of the current study was to assess bleeding events, including severity, localisation and prognostic impact, in a real world population of men and women with myocardial infarction (MI). Methods and results: In total 850 consecutive patients were included during 2010 and followed for one year. Bleeding complications were identified by searching of each patients medical records and characterised according to the TIMI criteria. For this analysis, only the first event was calculated. The total incidence of bleeding events was 24.4% (81 women and 126 men, p=ns). The incidence of all inhospital bleeding events was 13.2%, with no sex difference. Women had significantly more minor non-surgery related bleeding events than men (5% vs 2.2%, p=0.02). During follow-up, 13.5% had a bleeding, with more non-surgery related bleeding events among women, 14.7% vs 9.7% (p=0.03). The most common bleeding localisation was the gastrointestinal tract, more in women than men (12.1% vs 7.6%, p=0.03). Women had also more access site bleeding complications (4% vs 1.7%, p=0.04), while men had more surgery related bleeding complications (6.4% vs 0.9%, p=0.001). Increased mortality was found only in men with non-surgery related bleeding events (p=0.008). Conclusions: Almost one in four patients experienced a bleeding complication through 12 months follow-up after a myocardial infarction. Women experienced more non-surgery related minor/minimal bleeding complications than men, predominantly GI bleeding events and access site bleeding events, with no apparent impact on outcome. In contrast men with non-surgery related bleeding complications had higher mortality. Improved bleeding prevention strategies are warranted for both men and women.

    Gender difference in prognostic impact of in-hospital bleeding after myocardial infarction - data from the SWEDEHEART registry.2016In: European heart journal. Acute cardiovascular care, ISSN 2048-8734, Vol. 6, p. 463-472Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Bleeding complications increase mortality in myocardial infarction patients. Potential gender difference in bleeding regarding prevalence and prognostic impact is still controversial.

    OBJECTIVES: Gender comparison regarding incidence and prognostic impact of bleeding in patients hospitalised with myocardial infarction during 2006-2008.

    METHODS: Observational study from the SWEDEHEART register. Outcomes were in-hospital bleedings, in-hospital mortality and one-year mortality in hospital survivors.

    RESULTS: A total number of 50,399 myocardial infarction patients were included, 36.6% women. In-hospital bleedings were more common in women (1.9% vs. 3.1%, p<0.001) even after multivariable adjustment (odds ratio (OR) 1.17, 95% confidence interval (CI) 1.01-1.37). The increased risk for women was found in ST-elevation myocardial infarction (OR 1.46, 95% CI 1.10-1.94) and in those who underwent percutaneous coronary intervention (OR 1.80, 95% CI 1.45-2.24). In contrast the risk was lower in medically treated women (OR 0.79, 95% CI 0.62-1.00). After adjustment, in-hospital bleeding was associated with higher risk of one-year mortality in men (OR 1.35, 95% CI 1.04-1.74), whereas this was not the case in women (OR 0.97, 95% CI 0.72-1.31).

    CONCLUSIONS: Female gender is an independent risk factor of in-hospital bleeding after myocardial infarction. A higher bleeding risk in women appeared to be restricted to invasively treated patients and ST-elevation myocardial infarction patients. Even though women have higher short- and long-term mortality, there was no difference between the genders among bleeders. After multivariable adjustment the prognostic impact of bleeding complications was higher in men.

    Gender perspective on risk factors, coronary lesions and long-term outcome in young patients with ST-elevation myocardial infarction2010In: Heart, ISSN 1355-6037, E-ISSN 1468-201X, Vol. 96, no 6, p. 453-459Article in journal (Refereed)
    Abstract [en]

    Objective Previous data on young patients with acute coronary syndrome (ACS) have indicated higher rates of normal coronary angiograms but higher mortality in women than men. However, ST-elevation myocardial infarction (STEMI) differs from non-ST-elevation ACS in many aspects. We elucidated sex differences in risk factors, angiographic findings and outcome in consecutive STEMI patients below 46 years of age. Design Retrospective cohort study. Setting The Swedish registers for CCU care and coronary angioplasty; RIKS-HIA and SCAAR. Patients 2132 STEMI patients below 46 years of age admitted to intensive coronary care units in Sweden between 1995 and 2006 and followed for at least 1 year. Main outcome measures Angiographic findings and short-term and long-term mortality. Results Risk factors were more common in women. Significant coronary lesions were equally common (92.1% vs 93.1%, p=0.64) while single vessel disease was more common (72.9% vs 59.3%; pandlt;0.001) in women. Women had higher multivariable adjusted in-hospital mortality, OR 2.85 (95% CI 1.31 to 6.19) while long-term mortality was the same, HR 0.93 (95% CI 0.60 to 1.45). The catch-up of mortality in men might be related to a higher occurrence of re-infarctions, HR 1.82 (95% CI 1.25 to 2.65). Conclusions STEMI below age 46 is a more rare condition in women than in men and more often related to cardiovascular risk factors. More than 90% of both men and women had coronary lesions, in women more often single vessel lesions. Female sex is associated with higher in-hospital mortality, while long-term mortality is low without difference between genders.

    Gender difference in prevalence and prognostic impact of renal insufficiency in patients with ST-elevation myocardial infarction treated with primary percutaneous coronary intervention2011In: Heart, ISSN 1355-6037, E-ISSN 1468-201X, Vol. 97, no 4, p. 308-314Article in journal (Refereed)
    Abstract [en]

    Objective To evaluate if female gender is associated with renal insufficiency in patients with ST-elevation myocardial infarction (STEMI) and if there is a gender difference in the prognostic importance of renal insufficiency in STEMI. Design Single-centre observational study. Setting One tertiary cardiac centre. Patients All consecutive patients with STEMI planned for primary percutaneous coronary intervention in one Swedish county in 2005 (98 women and 176 men). Main outcome measures Logistic regression analyses were conducted to evaluate the predictors of renal insufficiency, associations between estimated glomerular filtration rate (eGFR) and outcome in each gender and a possible interaction between gender and eGFR regarding outcome. Results Renal insufficiency was defined as eGFR less than 60 ml/min per 1.73 m(2). 67% of women had renal insufficiency compared with 26% of men, OR 5.06 (95% CI 2.66 to 9.59) after multivariable adjustment. In women each 10 ml/min per 1.73 m 2 increment of eGFR was associated with a 63% risk reduction for 1-year mortality, OR 0.37 (95% CI 0.15 to 0.89). No such association was found in men, OR 1.05 (95% CI 0.63 to 1.76). A trend towards a significant interaction between gender and eGFR regarding 1-year mortality was found, OR 2.05 (95% CI 0.93 to 4.50). Conclusions A considerable gender difference in the prevalence of renal insufficiency in STEMI was found and renal insufficiency seemed to be a more important prognostic marker in women. These results are important as previous STEMI studies have shown higher multivariable adjusted mortality in women than in men but renal function has seldom been taken into consideration.

    Management and Outcome in ST-Elevation Myocardial Infarction from a Gender Perspective2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The aim of this thesis was to evaluate baseline characteristics, management and outcome in real life ST-elevation myocardial infarction [STEMI] cohorts from a gender perspective. We aimed to evaluate the total STEMI population as well as certain subgroups, such as the youngest. Moreover we aimed to analyse gender differences in renal function, and the prognostic impact of reduced renal function in men and women with STEMI.

    In Paper I all STEMI patients registered in RIKS-HIA between 1st Jan 1995 and 31st Dec 2006 were included, in total 54 146 patients, 35% women. Women were 7 years older than men, with 30 min longer median symptomto-door time. They had higher prevalence of co-morbidities such as diabetes, hypertension and heart failure whereas men were more often smokers, had a previous myocardial infarction [MI] or were previously revascularised. During hospital care, fewer women than men, 63% vs. 72%, p<0.001, received acute reperfusion therapy, odds ratio [OR] 0.83 (95% confidence interval [CI] 0.79 – 0.88) after multivariable adjustment. Inhospital mortality was 13% vs. 7%, women vs. men, p<0.001. After multivariable adjustments women had 22% higher risk of in-hospital death, OR 1.22 (95% CI 1.11 – 1.33). Adding reperfusion therapy to the adjustment model did not change the odds of death, OR 1.21 (1.11 – 1.32). Stratifying the cohort into four age-groups revealed increased mortality with increasing age as well as higher mortality in women than in men in all groups. The multivariable adjusted risk in women relative to men was highest amongst the youngest, OR 1.45 (95% CI 0.98 – 2.14). The long term prognosis was assessed in women vs. men with Cox proportional regression analyses, follow-up time 1 to 13 years. Women had 8% lower risk of long term mortality after multivariable adjustments, and after age-stratifying, women had better long term survival in all age-groups, except the youngest.

    Previous studies based on mixed MI cohorts had found a gender-age interaction with higher risk of death women relative to men in the youngest group. In Paper II we included all STEMI patients <46 years old registered in RIKS-HIA between 1st Jan 1995 and 31st Dec 2006, 1748 men and 384 women. Cardiovascular risk factors were common, and women had more often clustering of risk factors compared to men. The most prevalent risk factor was smoking, 64% of the women compared to 58% of the men were current smokers. There was no gender difference in delay times or in rate of reperfusion. Almost 60% of both women and men underwent coronary angiography within one week. There was no gender difference in prevalence of non-obstructive disease, (p=0.64), but men had had multi-vessel/left main disease much more often than women (33.6% vs. 19.2%; p<0.001). In-hospital mortality was low, 3% in women vs. 1% in men, crude OR women vs. men 2.83 (95% CI 1.32 – 6.03). Female gender appeared as an independent predictor in the multivariable model of in-hospital mortality, OR 2.85 (95% CI 1.31– 6.19). When the cohort was followed up to 10 years (mean 5.4 years) the risk of mortality was not higher in women (hazard ratio [HR] 0.93, 95% CI 0.60 – 1.45; p=0.75), and men had significantly higher risk of a second new MI during the following 10 years, HR 1.82 (95% CI 1.25 – 2.65; p=0.002).

    In the beginning of the 21st century there was a shift in reperfusion strategy with a decline in use of fibrinolytic therapy and an increase in use of primary PCI. We hypothesised that the gender differences noticed during the fibrinolytic era with lower chance of receiving reperfusion therapy and higher risk of early mortality in women, would have diminished during the new primary PCI era, as this is a better reperfusion strategy, especially for women. In Paper III we included STEMI patients from two time periods with different dominating reperfusion strategies in order to compare management and outcome between genders in both periods. Patients in the early period (n=15 697, 35% women) were registered in RIKS-HIA between 1st Jan 1998 and 31st Dec 2000 and those in the late period (n=14 380, 35% women) between 1st Jan 2004 and 31st Dec 2006. Among patients treated with reperfusion therapy 9% in the early compared to 68% in the late period were treated with primary PCI. The use of reperfusion therapy increased between the two periods, in men from 70.9% to 75.3%, in women from 63.1% to 63.6%. After multivariable adjustment, women were 14% and 20% less likely than men to receive reperfusion therapy, early and late periods, respectively. Heart failure, cardiogenic chock and major bleedings were more common in women compared to men. Evidence-based secondary preventive therapies were prescribed more often in the late compared to the early period in both genders, but more seldom to women in both periods. After multivariable adjustments women still had less chance of receiving ACE-inhibitors/ARBs but higher chance of receiving statins in the early period. In the late period women had 14 – 25% less chance of receiving any of the evidence-based secondary preventive therapies.

    In Paper IV all consecutive patients who fulfilled the criteria for ST-elevation or bundle branch block on admission ECG and who were planned to undergo immediate coronary angiography with the intention to perform primary PCI at the Department of Cardiology in Linköping were included, 98 women and 176 men. Estimated glomerular filtration rate [eGFR] according to Modification of Diet in Renal Disease study [MDRD] was calculated for all patients and they were staged into CKD stages 1-5. Estimated GFR was lower in women than in men, mean eGFR 54 vs. 68 mL/min/1.73m2, p<0.001. Ten men but no woman were classified belonging to the best CKD stage 1(eGFR >90 mL/min/1.73m2). In total 67% of women compared to 27% of men were classified as having renal insufficiency [RI] (eGFR <60 mL/min/1.73m2) and female sex was a strong independent factor associated with RI, OR 5.06 (95% CI 2.66 – 9.59). Reduced eGFR per 10 mL/min decline was independently associated to higher risk of death and MACE (death, new MI or stroke) within one year in women whereas we found no such associations in men. There was a borderline significant interaction between gender and eGFR regarding one year mortality (p=0.08) but not regarding MACE (p=0.11).

    As we found a remarkable gender difference in RI prevalence in Paper  IV, we analysed an updated SWEDEHEART database including the years since S-creatinine became a mandatory variable to register. In Paper V all STEMI patients registered between 1st of Jan 2003 and 31st of Dec 2009 were included, in total 37 991 patients (36% women). RI was present in 38% in women vs. 19% in men according to MDRD and in 50% of men vs. 22% of men according to Cockcroft Gault [CG] (p<0.001 for both comparisons). Female gender was independently associated with RI regardless of used formula. In both genders, RI patients were older, had higher co-morbidity, suffered from more complications and had lower chance of receiving reperfusion therapy and evidence-based therapy at discharge compared to non RI patients. Among both RI and non RI patients, men had significantly higher chance than women of getting these therapies. In-hospital mortality was four to five times higher in RI vs. non RI patients. RI compared to non RI patients had approximately doubled risk of inhospital mortality in women and 2.5 times higher risk in men after multivariable adjustment. Regardless of used formula, the risk of dying at hospital increased with approximately 30% and the risk of long term mortality with approximately 10% in both genders per 10 mL/min decline of eGFR. There was no significant interaction between gender and eGFR regarding short- or long term outcome according to any of the formulas. Women had twice as high in-hospital and also higher cumulative long term mortality than men. After multivariable adjustments including all confounders except kidney function women had 7% lower risk of long term mortality but still 11% higher risk of in-hospital mortality. If eGFR according to any of the formulas was also included, there was no longer a gender difference regarding in-hospital mortality and women had lower risk of long term mortality. This was also the case if only adjusting for eGFR according to CG.

    Conclusion: In the real life STEMI setting, women were older with higher co-morbidity, longer delay, more complications and twice as high in-hospital mortality. They had significantly less chance of receiving acute reperfusion therapy, also after adjusting for possible confounders. During the fibrinolytic era women had higher risk of severe bleedings. We hypothesised that the gap in management would have decreased during the new primary PCI era, with a less time-dependent regime with less risk of fatal complications. Our hypothesis failed, and future studies ought to further scrutinise this gender difference in management. The less chance of reperfusion therapy did anyhow not explain the higher in-hospital mortality in women, which was 10-20% higher after multivariable adjustments, consistent with previous findings. Moderate to severe chronic kidney disease was very common in women with STEMI, 50% according to the Cockcroft Gault formula. Estimated GFR has seldom been taken into account in studies evaluating gender differences in outcome. If adjustment for eGFR was done, alone or added to the all other co-variates, women had no longer higher risk of in-hospital mortality. Adjusted long term outcome was better in women than in men, which was also the case in the youngest cohort when studied separately.

    Abstract [en]

    Background: Previous studies of patients admitted for ST-elevation myocardial infarction [STEMI] have indicated that women have a higher risk of early mortality than do men. These studies have presented limited information on gender related differences in the short term and almost no information on the long term. Methods and results: We analysed a prospective, consecutively included STEMI population consisting of 54,146 patients (35% women). This population consists of almost all patients hospitalised in Sweden between January 1, 1995 and December 31, 2006 as recorded in the SWEDEHEART register (formerly RIKS-HIA). Follow-up time ranged from one to 13 years (mean 4.6). Women had a lower probability of being given reperfusion therapy, odds ratio [OR] 0.83 (95% confidence interval [CI] 0.79-0.88). During the time these STEMI patients were in the hospital, 13% of the women and 7% of men died, multivariable adjusted OR 1.21 (95% CI 1.11-1.32). During the follow up period, 46% of the women died as compared with 32% of the men. There was, however, no gender difference in age-adjusted risk of long term mortality (hazard ratio [HR] 0.98, 95% CI 0.95-1.01) whereas the multivariable adjusted risk was lower in women (HR 0.92, 95% CI 0.89-0.96). The long term risk of re-infarction was the same in men and women (HR 0.98, 95% CI 0.93-1.03) whereas men in the youngest group had a higher risk than women in that age group (HR 0.82, 95% CI 0.72-0.94). Conclusion: In STEMI, women had a higher risk of in-hospital mortality but the long-term risk of death was higher in men. More studies are needed in the primary percutaneous coronary intervention (pPCI) era that are designed to determine why women fare worse than men after STEMI during the first phase when they are in hospital

    Abstract [en]

    Objective Previous data on young patients with acute coronary syndrome (ACS) have indicated higher rates of normal coronary angiograms but higher mortality in women than men. However, ST-elevation myocardial infarction (STEMI) differs from non-ST-elevation ACS in many aspects. We elucidated sex differences in risk factors, angiographic findings and outcome in consecutive STEMI patients below 46 years of age. Design Retrospective cohort study. Setting The Swedish registers for CCU care and coronary angioplasty; RIKS-HIA and SCAAR. Patients 2132 STEMI patients below 46 years of age admitted to intensive coronary care units in Sweden between 1995 and 2006 and followed for at least 1 year. Main outcome measures Angiographic findings and short-term and long-term mortality. Results Risk factors were more common in women. Significant coronary lesions were equally common (92.1% vs 93.1%, p=0.64) while single vessel disease was more common (72.9% vs 59.3%; pandlt;0.001) in women. Women had higher multivariable adjusted in-hospital mortality, OR 2.85 (95% CI 1.31 to 6.19) while long-term mortality was the same, HR 0.93 (95% CI 0.60 to 1.45). The catch-up of mortality in men might be related to a higher occurrence of re-infarctions, HR 1.82 (95% CI 1.25 to 2.65). Conclusions STEMI below age 46 is a more rare condition in women than in men and more often related to cardiovascular risk factors. More than 90% of both men and women had coronary lesions, in women more often single vessel lesions. Female sex is associated with higher in-hospital mortality, while long-term mortality is low without difference between genders.

    Abstract [en]

    Objective In ST elevation myocardial infarction women received less evidence-based medicine and had worse outcome during the fibrinolytic era. With the shift to primary percutaneous coronary intervention (pPCI) as preferred reperfusion strategy, the authors aimed to investigate whether these gender differences has diminished.

    Design, setting and participants Cohort study including consecutive ST elevation myocardial infarction patients registered 1998–2000 (n=15 697) and 2004–2006 (n=14 380) in the Register of Information and Knowledge about Swedish Heart Intensive care Admissions.

    Outcome measures 1. Use of evidence-based medicine such as reperfusion therapy (pPCI or fibrinolysis) and evidence-based drugs at discharge. 2. Inhospital and 1-year mortality.

    Results Of those who got reperfusion therapy, pPCI was the choice in 9% in the early period compared with 68% in the late period. In the early period, reperfusion therapy was given to 63% of women versus 71% of men, p<0.001. Corresponding figures in the late period were 64% vs 75%, p<0.001. After multivariable adjustments, the ORs (women vs men) were 0.86 (95% CI 0.78 to 0.94) in the early and 0.80 (95% CI 0.73 to 0.89) in the late period. As regards evidence-based secondary preventive drugs at discharge in hospital survivors (platelet inhibitors, statins, ACE inhibitors/angiotensin receptor blockers and β-blockers), there were small gender differences in the early period. In the late period, women had 14%–25% less chance of receiving these drugs, OR 0.75 (95% CI 0.68 to 0.81) through 0.86 (95% CI 0.73 to 1.00). In both periods, multivariable-adjusted inhospital mortality was higher in women, OR 1.18 (95% CI 1.02 to 1.36) and 1.21 (1.00 to 1.46). One-year mortality was gender equal, HR 0.95 (95% CI 0.87 to 1.05) and 0.96 (0.86 to 1.08), after adding evidence-based medicine to the multivariable adjustments.

    Conclusion In spite of an intense gender debate, focus on guideline adherence and the change in reperfusion strategy, the last decade gender differences in use of reperfusion therapy and evidence-based therapy at discharge did not decline during the study period, rather the opposite. Moreover, higher mortality in women persisted.

    Abstract [en]

    Background: Data indicate that female gender may be associated with increased risk of RI in MI but also that presence of RI has higher prognostic impact in women. In case of ST-elevation MI [STEMI], women have higher adjusted mortality compared to men but RI has seldom been taken into account.

    Methods and Results: All STEMI patients registered in the Swedish national quality register SWEDEHEART between 2003 and 2009 were included (37991 patients, 66% men). Based on s-creatinine on admission, glomerular filtration rate [GFR] was estimated according to MDRD and Cockcroft-Gault [CG]. RI was defined as eGFR below 60 mL/min. Women had 1.6-2.2 times higher multivariable adjusted risk of RI and half of all women had RI according to CG. RI was associated with 2-2.5 times higher risk of in-hospital and approximately 1.5 times higher risk of long-term mortality in both genders. Each 10 mL/min decline of eGFR was associated with 22-33% and 9-16% increased risk of in-hospital and. long-term mortality, respectively. There was no significant interaction between gender and eGFR regarding outcome. Both in-hospital and long-term mortality was twice as high in women but after adjusting for eGFR according to CG, there was no longer any gender difference in early outcome and long term outcome was better in women.

    Conclusions: Among STEMI patients

    1) Female sex was independently associated with RI

    2) Reduced eGFR regardless of used formula was a strong independent risk factor for mortality without a significant gender difference in prognostic impact.

    3) Reduced eGFR (according to CG) appeared to be a main explanatory variable to the higher mortality in women.

    A gender perspective on short- and long term mortality in ST-elevation myocardial infarction: a report from the SWEDEHEART register2013In: International Journal of Cardiology, ISSN 0167-5273, E-ISSN 1874-1754, Vol. 18, no 2, p. 1041-1047Article in journal (Refereed)
    Abstract [en]

    Background: Previous studies of patients admitted for ST-elevation myocardial infarction [STEMI] have indicated that women have a higher risk of early mortality than do men. These studies have presented limited information on gender related differences in the short term and almost no information on the long term. Methods and results: We analysed a prospective, consecutively included STEMI population consisting of 54,146 patients (35% women). This population consists of almost all patients hospitalised in Sweden between January 1, 1995 and December 31, 2006 as recorded in the SWEDEHEART register (formerly RIKS-HIA). Follow-up time ranged from one to 13 years (mean 4.6). Women had a lower probability of being given reperfusion therapy, odds ratio [OR] 0.83 (95% confidence interval [CI] 0.79-0.88). During the time these STEMI patients were in the hospital, 13% of the women and 7% of men died, multivariable adjusted OR 1.21 (95% CI 1.11-1.32). During the follow up period, 46% of the women died as compared with 32% of the men. There was, however, no gender difference in age-adjusted risk of long term mortality (hazard ratio [HR] 0.98, 95% CI 0.95-1.01) whereas the multivariable adjusted risk was lower in women (HR 0.92, 95% CI 0.89-0.96). The long term risk of re-infarction was the same in men and women (HR 0.98, 95% CI 0.93-1.03) whereas men in the youngest group had a higher risk than women in that age group (HR 0.82, 95% CI 0.72-0.94). Conclusion: In STEMI, women had a higher risk of in-hospital mortality but the long-term risk of death was higher in men. More studies are needed in the primary percutaneous coronary intervention (pPCI) era that are designed to determine why women fare worse than men after STEMI during the first phase when they are in hospital

    Time trends in STEMI—improved treatment and outcome but still a gender gap: a prospective observational cohort study from the SWEDEHEART register2012In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 2, no 2Article in journal (Refereed)
    Abstract [en]

    Objective In ST elevation myocardial infarction women received less evidence-based medicine and had worse outcome during the fibrinolytic era. With the shift to primary percutaneous coronary intervention (pPCI) as preferred reperfusion strategy, the authors aimed to investigate whether these gender differences has diminished.

    Design, setting and participants Cohort study including consecutive ST elevation myocardial infarction patients registered 1998–2000 (n=15 697) and 2004–2006 (n=14 380) in the Register of Information and Knowledge about Swedish Heart Intensive care Admissions.

    Outcome measures 1. Use of evidence-based medicine such as reperfusion therapy (pPCI or fibrinolysis) and evidence-based drugs at discharge. 2. Inhospital and 1-year mortality.

    Results Of those who got reperfusion therapy, pPCI was the choice in 9% in the early period compared with 68% in the late period. In the early period, reperfusion therapy was given to 63% of women versus 71% of men, p<0.001. Corresponding figures in the late period were 64% vs 75%, p<0.001. After multivariable adjustments, the ORs (women vs men) were 0.86 (95% CI 0.78 to 0.94) in the early and 0.80 (95% CI 0.73 to 0.89) in the late period. As regards evidence-based secondary preventive drugs at discharge in hospital survivors (platelet inhibitors, statins, ACE inhibitors/angiotensin receptor blockers and β-blockers), there were small gender differences in the early period. In the late period, women had 14%–25% less chance of receiving these drugs, OR 0.75 (95% CI 0.68 to 0.81) through 0.86 (95% CI 0.73 to 1.00). In both periods, multivariable-adjusted inhospital mortality was higher in women, OR 1.18 (95% CI 1.02 to 1.36) and 1.21 (1.00 to 1.46). One-year mortality was gender equal, HR 0.95 (95% CI 0.87 to 1.05) and 0.96 (0.86 to 1.08), after adding evidence-based medicine to the multivariable adjustments.

    Conclusion In spite of an intense gender debate, focus on guideline adherence and the change in reperfusion strategy, the last decade gender differences in use of reperfusion therapy and evidence-based therapy at discharge did not decline during the study period, rather the opposite. Moreover, higher mortality in women persisted.

    Prevalence and prognostic impact of chronic kidney disease in STEMI from a gender perspective: data from the SWEDEHEART register, a large Swedish prospective cohort.2015In: BMJ open, ISSN 2044-6055, Vol. 5, no 6, p. e008188-Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: Gender differences in prevalence and prognostic impact of chronic kidney disease (CKD) in ST segment elevation myocardial infarction (STEMI) have been poorly evaluated. In STEMI, female gender has been independently associated with an increased risk of mortality. CKD has been found to be an important prognostic marker in myocardial infarction. The aim of this study was to evaluate gender differences in prevalence and prognostic impact of CKD on short-term and long-term mortality.

    DESIGN: Prospective observational cohort study.

    SETTING: The national quality register SWEDEHEART was used. In the beginning of the study period, 94% of the Swedish coronary care units contributed data to the register, which subsequently increased to 100%. The glomerular filtration rate was estimated (eGFR) according to Modification of Diet in Renal Disease Study (MDRD) and Cockcroft-Gault (CG).

    PARTICIPANTS: All patients with STEMI registered in SWEDEHEART from the years 2003-2009 were included (37,991 patients, 66% men).

    MAIN RESULTS: Women had 1.6 (MDRD) to 2.2 (CG) times higher multivariable adjusted risk of CKD. Half of the women had CKD according to CG. CKD was associated with 2-2.5 times higher risk of in-hospital mortality and approximately 1.5 times higher risk of long-term mortality in both genders. Each 10 mL/min decline of eGFR was associated with an increased risk of in-hospital and long-term mortality (22-33% and 9-16%, respectively) and this did not vary significantly by gender. Both in-hospital and long-term mortality were doubled in women. After multivariable adjustment including eGFR, there was no longer any gender difference in early outcome and the long-term outcome was better in women.

    CONCLUSIONS: Among patients with STEMI, female gender was independently associated with CKD. Reduced eGFR was a strong independent risk factor for short-term and long-term mortality without a significant gender difference in prognostic impact and seems to be an important reason why women have higher mortality than men with STEMI.

    Gender disparities in first medical contact and delay in ST-elevation myocardial infarction: a prospective multicentre Swedish survey study2018In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 8, no 5, article id e020211Article in journal (Refereed)
    Abstract [en]

    Objectives Compare gender disparities in ST-elevation myocardial infarction (STEMI) regarding first medical contact (FMC) and prehospital delay times and explore factors associated with prehospital delay in men and women separately. Design Cross-sectional study based on medical records and a validated questionnaire. Eligible patients were enrolled within 24 hours after admittance to hospital. Setting Patients were included from November 2012 to January 2014 from five Swedish hospitals with catheterisation facilities 24/7. Participants 340 men and 109 women aged between 31 and 95 years completed the survey. Main outcome measures FMC were divided into five possible contacts: primary healthcare centre by phone or directly, national advisory nurse by phone, emergency medical services (EMS) and emergency room directly. Two parts of prehospital delay times were studied: time from symptom onset to FMC and time from symptom onset to diagnostic ECG. Results Women more often called an advisory nurse as FMC (28% vs 18%, p=0.02). They had a longer delay until FMC, 90 (IOR 39-221) vs 66 (28-161) min, p=0.04 and until ECG, 146 (68-316) vs 103 (61-221) min, p=0.03. Men went to hospital because of believing they were stricken by an MI to a higher extent than women did (25% vs 15%, p=0.04) and were more often recommended to call EMS by bystanders (38% vs 22%, pamp;lt;0.01). Hesitating about going to hospital and experiencing pain in the stomach/back/shoulders were factors associated with longer delays in women. Believing the symptoms would disappear or interpreting them as nothing serious were corresponding factors in men. In both genders bystanders acting by contacting EMS explained shorter prehospital delays. Conclusions In STEMI, women differed from men in FMC and they had longer delays. This was partly due to atypical symptoms and a longer decision time. Bystanders acted more promptly when men than when women fell ill. Public knowledge of MI symptoms, and how to act properly, still seems insufficient.

    Gender differences in symptom presentation of ST-elevation myocardial infarction - An observational multicenter survey study2018In: International Journal of Cardiology, ISSN 0167-5273, E-ISSN 1874-1754, Vol. 264Article in journal (Refereed)
    Abstract [en]

    Background: Symptom presentation has been sparsely studied from a gender perspective restricting the inclusion to ST elevation myocardial infarction (STEMI) patients. Correct symptom recognition is vital in order to promptly seek care in STEMI where fast reperfusion therapy is of utmost importance. Female gender has been found associated with atypical presentation in studies on mixed MI populations but it is unclear whether this is valid also in STEMI. Objectives: We assessed whether there are gender differences in symptoms and interpretation of these in STEMI, and if this is attributable to sociodemographic and clinical factors. Methods: SymTime was a multicenter observational study including a validated questionnaire and data from medical records. Eligible STEMI patients (n = 532) were enrolled within 24 h after admittance at five Swedish hospitals. Results: Women were older, more often single and had lower educational level. Chest pain was less prevalent in women (74 vs 93%, p amp;lt; 0.001), whereas shoulder (33 vs 15%, p amp;lt; 0.001), throat/neck (34 vs 18%, p amp;lt; 0.001), back pain (29 versus 12%, p amp;lt; 0.001) and nausea (49 vs 29%, p amp;lt; 0.001) were more prevalent. Women less often interpreted their symptoms as of cardiac origin (60 vs 69%, p = 0.04). Female gender was the strongest independent predictor of non-chest pain presentation, odds ratio 5.29, 95% confidence interval 2.85-9.80. Conclusions: A striking gender difference in STEMI symptoms was found. As women significantly misinterpreted their symptoms more often, it is vital when informing about MI to the society or to high risk individuals, to highlight also other symptoms than just chest pain.

    First medical contact in patients with STEMI and its impact on time to diagnosis; an explorative cross-sectional study2015In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 5, no 4, p. e007059-Article in journal (Refereed)
    Abstract [en]

    Objective: It is unknown into what extent patients with ST-elevation myocardial infarction (STEMI) utilise a joint service number (Swedish Healthcare Direct, SHD) as first medical contact (FMC) instead of Emergency Medical Services (EMS) and how this impact time to diagnosis. We aimed to (1) describe patients FMC; (2) find explanatory factors influencing their FMC (ie, EMS and SHD) and (3) explore the time interval from symptom onset to diagnosis. Setting: Multicentred study, Sweden. Methods: Cross-sectional, enrolling patients with consecutive STEMI admitted within 24 h from admission. Results: We included 109 women and 336 men (mean age 66 +/- 11 years). Although 83% arrived by ambulance to the hospital, just half of the patients (51%) called EMS as their FMC. Other utilised SHD (21%), contacted their primary healthcare centre (14%), or went directly to the emergency room (14%). Reasons for not contacting EMS were predominantly; (1) my transport mode was faster (40%), (2) did not consider myself sick enough (30%), and (3) it was easier to be driven or taking a taxi (25%). Predictors associated with contacting SHD as FMC were female gender (OR 1.92), higher education (OR 2.40), history of diabetes (OR 2.10), pain in throat/neck (OR 2.24) and pain intensity (OR 0.85). Predictors associated with contacting EMS as FMC were history of MI (OR 2.18), atrial fibrillation (OR 3.81), abdominal pain (OR 0.35) and believing the symptoms originating from the heart (OR 1.60). Symptom onset to diagnosis time was significantly longer when turning to the SHD instead of the EMS as FMC (1: 59 vs 1: 21 h, pless than0.001). Conclusions: Using other forms of contacts than EMS, significantly prolong delay times, and could adversely affect patient prognosis. Nevertheless, having the opportunity to call the SHD might also, in some instances, lower the threshold for taking contact with the healthcare system, and thus lowers the number that would otherwise have delayed even longer.

    Early treatment with abciximab in patients with ST elevation myocardial infarction results in a high rate of normal or near normal blood flow in the infarct related artery2010In: Acute cardiac care, ISSN 1748-295X, Vol. 12, no 1, p. 10-17Article in journal (Refereed)
    Abstract [en]

    There is debate whether early treatment with GpIIb/IIIa inhibitors is of clinical benefit in primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI). This study explored the effects of early given abciximab on coronary blood flow and major adverse cardiac events (MACE) in patients with STEMI treated with primary PCI and adjunctive abciximab. We studied all consecutive patients from our catchment area with STEMI undergoing acute angiography with the intention of primary PCI during 2005. Abciximab was given as early pre-treatment before, (n = 133) or at the cath. lab. after a diagnostic angiography (n = 109). Pre-procedural TIMI 2-3 flow was observed in 45.9 % of patients in the early group versus 20.2 % in the cath. lab. group, P = 0.0001. Mortality rates were 3.8 % versus 3.7% inhospital and 8.3 % versus 7.3% at one year in the early respectively the cath. lab. group, both P = NS. The MACE rate (death, non fatal myocardial infarction, unplanned revascularization) at one year was 19.5 % (early group) and 26.6 % (cath. lab. group), P = 0.19. CONCLUSION: In this single centre registry study of unselected patients with STEMI early given abciximab was associated with a significantly higher rate of TIMI 2-3 flow compared to abciximab given after the acute angiography.

    Glomerular filtration rate (GFR) during and after STEMI: a single-centre, methodological study comparing estimated and measured GFR2015In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 5, no 9, p. 1-8, article id e007835Article in journal (Refereed)
    Abstract [en]

    Objectives: To validate the performance of the most commonly used formulas for estimation of glomerular filtration rate (GFR) against measured GFR during the index hospitalisation for ST-elevation myocardial infarction (STEMI). Setting: Single centre, methodological study. Participants: 40 patients with percutaneous coronary intervention-treated STEMI were included between November 2011 and February 2013. Patients on dialysis, cardiogenic shock or known allergy to iodine were excluded. Outcome measures: Creatinine and cystatin C were determined at admission and before discharge in 40 patients with STEMI. Clearance of iohexol was measured (mGFR) before discharge. We evaluated and compared the Cockcroft-Gault (CG), the Modification of Diet in Renal Disease (MDRD-IDMS), the Chronic Kidney Disease Epidemiology (CKD-EPI) and the Grubb relative cystatin C (rG-CystC) with GFR regarding correlation, bias, precision and accuracy (P30). Agreement between eGFR and mGFR to discriminate CKD was assessed by Cohens. statistics. Results: MDRD-IDMS and CKD-EPI demonstrated good performance to estimate GFR (correlation 0.78 vs 0.81%, bias -1.3% vs 1.5%, precision 17.9 vs 17.1 mL/min 1.73 m(2) and P30 82.5% vs 82.5% for MDRD-IDMS vs CKD-EPI). CKD was best classified by CKD-EPI (. 0.83). CG showed the worst performance (correlation 0.73%, bias -1% to 3%, precision 22.5 mL/min 1.73 m(2) and P30 75%). The rG-CystC formula had a marked bias of -17.8% and significantly underestimated mGFR (p=0.03). At arrival, CKD-EPI and rG-CystC had almost perfect agreement in CKD classification (kappa=0.87), whereas at discharge agreement was substantially lower (kappa=0.59) and showed a significant discrepancy in CKD classification (p=0.02). Median cystatin C concentration increased by 19%. Conclusions: In acute STEMI, CKD-EPI showed the best CKD-classification ability followed by MDRD-IDMS, whereas CG performed the worst. STEMI altered the performance of the cystatin C equation during the acute phase, suggesting that other factors might be involved in the rise of cystatin C.

    Pretreatment with ticagrelor may offset additional inhibition of platelet and coagulation activation with bivalirudin compared to heparin during primary percutaneous coronary intervention2018In: Thrombosis Research, ISSN 0049-3848, E-ISSN 1879-2472, Vol. 171, p. 38-44Article in journal (Refereed)
    Abstract [en]

    Background

    It remains unknown if bivalirudin compared to heparin confers any additional inhibition of platelet and coagulation activation during primary percutaneous coronary intervention(PPCI) after pretreatment with ticagrelor.

    Methods

    In this substudy of VALIDATE-SWEDEHEART trial, 103 patients pretreated with ticagrelor were randomized before PPCI to heparin or bivalirudin. Blood samples were collected before and 1 and 12 h after PPCI. We measured platelet reactivity (PR) using Multiplate, soluble P-selectin, thrombin-antithrombin complexes (TAT) and prothrombin fragments 1 + 2 (F1 + 2) as markers of platelet and coagulation activation.

    Results

    The median (IQR) time from ticagrelor administration to randomization was 63 (29) vs 60 (24) minutes, p = 0.28. ADP-induced PR did not significantly differ between groups over time (heparin vs bivalirudin, AUC 73 (62) vs 74 (68), p = 0.74, 32 (42) vs 43 (51), p = 0.38, 15 (15) vs 19 (15), p = 0.29, before, 1 and 12 h after PPCI). Soluble P-selectin did not significantly differ between groups. At 1 h TAT significantly increased with bivalirudin (3.0 (1.3) to 4.3 (4.2) ug/L; p < 0.01), but not with UFH (3.1 (2.1) to 3.5 (1.6) ug/L, p = 0.24). F1 + 2 increased in both groups but the rise was numerically higher with bivalirudin (170 (85) to 213 (126) pmol/L vs 168 (118) to 191 (103) pmol/L). At 12 h, a comparable significant increase in thrombin generation was observed in both groups.

    Conclusion

    In patients treated with ticagrelor, we found no major differences between bivalirudin and heparin in platelet aggregation or coagulation markers, which is in agreement with the neutral clinical results of the VALIDATE-SWEDEHEART study.

    Association between gender and short-term outcome in patients with ST elevation myocardial infraction participating in the international, prospective, randomised Administration of Ticagrelor in the catheterisation Laboratory or in the Ambulance for New ST elevation myocardial Infarction to open the Coronary artery (ATLANTIC) trial: a prespecified analysis2017In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 7, no 9, article id e015241Article in journal (Refereed)
    Abstract [en]

    Objectives To evaluate gender differences in outcomes in patents with ST-segment elevation myocardial infarction (STEMI) planned for primary percutaneous coronary intervention (PPCI). Settings A prespecified gender analysis of the multicentre, randomised, double-blind Administration of Ticagrelor in the catheterisation Laboratory or in the Ambulance for New ST elevation myocardial Infarction to open the Coronary artery. Participants Between September 2011 and October 2013, 1862 patients with STEMI and symptom duration amp;lt;6 hours were included. Interventions Patients were assigned to prehospital versus in-hospital administration of 180 mg ticagrelor. Outcomes The main objective was to study the association between gender and primary and secondary outcomes of the main study with a focus on the clinical efficacy and safety outcomes. Primary outcome: the proportion of patients who did not have 70% resolution of ST-segment elevation and did not meet the criteria for Thrombolysis In Myocardial Infarction (TIMI) flow 3 at initial angiography. Secondary outcome: the composite of death, MI, stent thrombosis, stroke or urgent revascularisation and major or minor bleeding at 30 days. Results Women were older, had higher TIMI risk score, longer prehospital delays and better TIMI flow in the infarct-related artery. Women had a threefold higher risk for all-cause mortality compared with men (5.7% vs 1.9%, HR 3.13, 95% CI 1.78 to 5.51). After adjustment, the difference was attenuated but remained statistically significant (HR 2.08, 95% CI 1.03 to 4.20). The incidence of major bleeding events was twofold to threefold higher in women compared with men. In the multivariable model, female gender was not an independent predictor of bleeding (Platelet Inhibition and Patient Outcomes major HR 1.45, 95% CI 0.73 to 2.86, TIMI major HR 1.28, 95% CI 0.47 to 3.48, Bleeding Academic Research Consortium type 3-5 HR 1.45, 95% CI 0.72 to 2.91). There was no interaction between gender and efficacy or safety of randomised treatment. Conclusion In patients with STEMI planned for PPCI and treated with modern antiplatelet therapy, female gender was an independent predictor of short-term mortality. In contrast, the higher incidence of bleeding complications in women could mainly be explained by older age and clustering of comorbidities.

    Sex-related response to bivalirudin and unfractionated heparin in patients with acute myocardial infarction undergoing percutaneous coronary intervention: A subgroup analysis of the VALIDATE-SWEDEHEART trial2019In: European Heart Journal. Acute Cardiovascular Care, ISSN 2048-8734, Vol. 8, no 6, p. 502-509Article in journal (Refereed)
    Abstract [en]

    Aims:

    Our aim was to study the impact of sex on anticoagulant treatment outcomes during percutaneous coronary intervention in acute myocardial infarction patients.

    Methods:

    This study was a prespecified analysis of the Bivalirudin versus Heparin in ST-Segment and Non ST-Segment Elevation Myocardial Infarction in Patients on Modern Antiplatelet Therapy in the Swedish Web System for Enhancement and Development of Evidence-based Care in Heart Disease Evaluated according to Recommended Therapies Registry Trial (VALIDATE-SWEDEHEART) trial, in which patients with myocardial infarction were randomised to bivalirudin or unfractionated heparin during percutaneous coronary intervention. The primary outcome was the composite of death, myocardial infarction or major bleeding at 180 days.

    Results:

    There was a lower risk of the primary outcome in women assigned to bivalirudin than to unfractionated heparin (13.6% vs 17.1%, hazard ratio 0.78, 95% confidence interval (0.60–1.00)) with no significant difference in men (11.8% vs 11.2%, hazard ratio 1.06 (0.89–1.26), p for interaction 0.05). The observed difference was primarily due to lower risk of major bleeding (Bleeding Academic Research Consortium definition 2, 3 or 5) associated with bivalirudin in women (8.9% vs 11.8%, hazard ratio 0.74 (0.54–1.01)) but not in men (8.5% vs 7.3%, hazard ratio 1.16 (0.94–1.43) in men, pfor interaction 0.02). Conversely, no significant difference in the risk of Bleeding Academic Research Consortium 3 or 5 bleeding, associated with bivalirudin, was found in women 4.5% vs 5.4% (hazard ratio 0.84 (0.54–1.31)) or men 2.9% vs 2.1% (hazard ratio 1.36 (0.93–1.99)). Bleeding Academic Research Consortium 2 bleeding occurred significantly less often in women assigned to bivalirudin than to unfractionated heparin. The risk of death or myocardial infarction did not significantly differ between randomised treatments in men or women.

    Conclusion:

    In women, bivalirudin was associated with a lower risk of adverse outcomes, compared to unfractionated heparin, primarily due to a significant reduction in Bleeding Academic Research Consortium 2 bleeds.

    Bivalirudin versus heparin with primary percutaneous coronary intervention2018In: American Heart Journal, ISSN 0002-8703, E-ISSN 1097-6744, Vol. 201, p. 9-16Article in journal (Refereed)
    Abstract [en]

    Background: Optimal adjunctive therapy in ST-segment elevation myocardial infarction (STEMI) patients treated with primary PCI (PPCI) remains a matter of debate. Our aim was to compare the efficacy and safety of bivalirudin to unfractionated heparin (UFH), with or without glycoprotein IIb/IIIa inhibitors (GPI) in a large real-world population, using data from the Swedish national registry, SWEDEHEART. Method: From 2008 to 2014 we identified 23,800 STEMI patients presenting within 12 hours from symptom onset treated with PPCI and UFH +/- GPI or bivalirudin +/- GPI. Primary outcomes included 30-day all-cause mortality and major in-hospital bleeding. Multivariable regression models and propensity score modelling were utilized to study adjusted association between treatment and outcome. Results: Treatment with UFH +/- GPI was associated with similar risk of 30-day mortality compared to bivalirudin +/- GPI (5.3% vs 5.5%, adjusted HR 0.94; 95% CI 0.82-1.07). The adjusted risk for 1-year mortality, 30-day and 1-year stent thrombosis and re-infarction did not differ significantly between UFH +/- GPI and bivalirudin +/- GPI. In contrast, treatment with UFH +/- GPI was associated with a significant higher risk of major in-hospital bleeding (adjusted OR 1.62; 95% CI 1.30-2.03). When including GPI use in the multivariable analysis, the difference was attenuated and no longer significant (adjusted OR 1.25; 95% CI 0.92-1.70). Conclusion: Bivalirudin +/- GPI was associated with significantly lower risk for major in hospital bleeding but no significant difference in 30-day or one year mortality, stent thrombosis or re-infarction compared with UFH +/- GPI. The bleeding reduction associated with bivalirudin could be explained by the greater GPI use with UFH. (C) 2018 Elsevier Inc. All rights reserved.

    Long-term efficacy of drug coated balloons compared with new generation drug-eluting stents for the treatment of de novo coronary artery lesions2018In: Catheterization and cardiovascular interventions, ISSN 1522-1946, E-ISSN 1522-726X, Vol. 92, no 5, p. E317-E326Article in journal (Refereed)
    Abstract [en]

    Background Studies comparing drug coated balloons (DCB) with new generation drug-eluting stents (nDES) for the treatment of de novo coronary artery lesions are lacking. Methods From 2009 to 2016, DCB or nDES used for treatment of de novo coronary lesions at our institution were included, in total 1,197 DEB and 6,458 nDES. We evaluated target lesions restenosis (TLR) and definite target lesion thrombosis (TLT). Propensity score modeling were utilized to study adjusted associations between treatment and outcomes. Results Median follow-up was 901days. DCB patients were older, with higher cardiovascular risk profile. Bailout stenting after DCB was performed in 8% of lesions. The cumulative rate of TLR and TLT was 7.0 vs. 4.9% and 0.2 vs. 0.8% for DCB vs. nDES, respectively. Before adjustment, DCB was associated with a higher risk of TLR [hazard ratio (HR) 1.44; 95% confidence interval (CI) 1.07-1.94] and a non-significantly lower risk of TLT (HR 0.30; 95% CI 0.07-1.24), compared to nDES. In the propensity matched population consisted of 1,197 DCB and 1,197 nDES, treatment with DCB was associated with similar risk for TLR (adjusted HR 1.05; 95% CI 0.72-1.53) but significantly lower risk for TLT (adjusted HR 0.18; 95% CI 0.04-0.82) compared to nDES. Conclusions Treatment with DCB was associated with a similar risk of TLR and a lower risk of definite TLT compared with nDES. In selected cases, DCB appears as a good alternative to nDES for the treatment of de novo coronary lesions.
