Effect of Physical Activity Assessment on Prognostication for Peripheral Artery Disease and Mortality

Abstract Objective To examine whether a simple question about the performance of regular vigorous activity is associated with peripheral artery disease (PAD) and mortality. Methods A total of 1288 individuals undergoing nonemergency coronary angiography were assessed for participation in regular vigorous activity by questionnaire. Data on demographic characteristics, ankle-brachial indexes, and cardiovascular outcomes were prospectively collected. Results Compared with those who denied participation in regular vigorous activity, those who reported participation were less likely to have PAD (odds ratio, 0.58; 95% CI, 0.39-0.86), had higher ankle-brachial indexes, had better Walking Impairment Questionnaire scores ( P
