Abstract

Objective: To investigate the effects of physical activity (PA) and tobacco use on adverse clinical outcomes after revascularisation for peripheral arterial disease (PAD) in the Western Pacific region, where PAD cases and tobacco use are among the highest in the world. Methods: This was a retrospective cohort study using the Korean National Health Insurance Service (NHIS) database and included patients who had received revascularisation for PAD between 2010 and 2015. They were categorised as active or inactive based on the number of days per week they engaged in PA and as current or non-tobacco users (self report). The primary outcome was all cause mortality. Secondary outcomes included major adverse outcome (a composite of all cause mortality, myocardial infarction, and stroke) and major adverse limb event (MALE, a composite of amputation and recurrent revascularisation). Results: The relatively healthy cohort comprised 8 324 patients (mean age 64.7 years; 76.9% male) following revascularisation for PAD. Among them, 32.7% were inactive and 26.4% were tobacco users. Active patients had better outcomes than inactive patients (all cause mortality adjusted hazard ratio [adjHR] 0.766; 95% CI 0.685 – 0.855, major adverse outcome adjHR 0.795; 95% CI 0.719 – 0.878, MALE adjHR 0.858; 95% CI 0.773 – 0.953). Tobacco users had poorer outcomes than non-users (all cause mortality adjHR 1.279; 95% CI 1.124 – 1.456, major adverse outcome adjHR 1.263; 95% CI 1.124 – 1.418, MALE adjHR 1.291; 95% CI 1.143 – 1.458). Conclusion: Even after receiving revascularisation for PAD, a sizable proportion of patients were physically inactive and used tobacco, leading to adverse clinical outcomes such as death, cardiovascular morbidity, and amputation in Korea. These modifiable risk factors should be addressed systematically, and a comprehensive approach including supervised exercise programmes and tobacco cessation is needed in patients with PAD.
