Abstract [en]

Background: In myocardial infarction (MI) rapid diagnosis and treatment is crucial for the prognosis. Previous research has found that symptom presentation influence pre hospital delay times but studies about differences in MI symptoms between patients with ST-elevation myocardial infarction (STEMI) and non ST-elevation myocardial infarction (NSTEMI) are sparse and inconclusive. To enhance the understanding of symptom presentation in regard to MI type, we aimed to describe symptoms in relation to MI type and to find predictors of STEMI versus NSTEMI in patients with MI.

Methods: Patients with MI (n=694) from the SymTime study were included. SymTime was a multicentre cross-sectional study of symptoms and actions in the prehospital phase of MI and data were collected using a previously validated questionnaire administered to MI patients within 24 h of admission to hospital.

Results: Patients with STEMI were younger, more often men and smokers. Patients with NSTEMI were more likely to have a history of hypertension, MI and stroke. Chest pain was the most common symptom in both groups. Pain, discomfort, or pressure located in the jaw or teeth, vertigo/pre-syncope, cold sweat and nausea/vomiting were significantly more frequent in patients with STEMI (Table 1). In a multivariate logistic regression model patients with STEMI were more likely to present with cold sweat (OR 4.13, 95% CI 2.71–6.29) jaw pain (OR 2.14, 95% CI 1.02–4.50), and nausea (OR 2.01, 95% CI 1.20–3.33), and less likely to have a history of stroke (OR 0.35, 95% CI 0.15–0.84), fluctuating symptoms (OR 0.54, 95% CI 0.36–0.83) and anxiety (OR 0.54, 95% CI 0.32–0.92) compared to patients with NSTEMI.

Conclusion: Patients with STEMI differed significantly from those with NSTEMI regarding symptom presentation. This knowledge is important for health care personnel to recognize symptoms alarming for STEMI when evaluating patients with MI symptoms.
