Abstract [en]
Aims
This study evaluates 10-year follow-up data on associated comorbidity, mortality, and pharmacological treatment patterns for men and women with different stages of peripheral arterial disease (PAD) in a population-based setting.
Methods and results
This was a prospective observational population-based cohort study, based on physical examinations and questionnaires at baseline supplemented with national register data between 2005 and 2015. Subjects were placed in subgroups defined by ankle–brachial index levels and reported symptoms; asymptomatic PAD (APAD), intermittent claudication (IC), severe limb ischaemia (SLI), or references (Ref). Cox proportional hazards regression models were used for analysis with adjustments for sex and baseline age and comorbidity. The cohort consisted of 5080 subjects (45% males). At baseline, APAD, IC, and SLI were prevalent in 559 (11%), 320 (6.3%), and 78 (1.5%) subjects, respectively. A significant increased risk for cardiovascular (CV) death, even when adjusted for age and baseline morbidity, were noted in all PAD stages as compared with reference group with a small difference between APAD and IC, an adjusted hazard ratio 1.80 (confidence interval 1.45–2.22) and 1.95 (1.50–2.53), respectively. Only about 60% of PAD subjects received medical prophylactic treatment as recommended in guidelines.
Conclusion
Peripheral arterial disease subjects had significantly increased CV morbidity and mortality risks, especially males. Asymptomatic PAD subjects confer similar risk for CV events as symptomatic patients. Our findings motivate enhanced preventive efforts of all PAD stages, including in asymptomatic disease.
