Patients with peripheral artery disease (PAD) often complain of reduced physical activity (PA) despite improvements in intermittent claudication after successful endovascular treatment (EVT). Sarcopenia resulting from chronic ischemia can affect post-EVT PA levels.
This study aims to assess the association between sarcopenia and post-EVT PA levels.
One hundred five patients with PAD were consecutively enrolled in this study. PA was assessed using the post-EVT step count and the pre-EVT International Physical Activity Questionnaire. Sarcopenia was diagnosed based on the Asia Working Group for Sarcopenia and defined as low muscle mass and strength, and/or slow walking speed. The patients were categorized into three groups: 1) patients with sarcopenia (Sarcopenia Group); 2) patients with only low muscle mass or strength, and/or slow walking speed (Suspected-Sarcopenia Group); and 3) patients who did not fulfill all the sarcopenia criteria (No-Sarcopenia Group).
Proportions of patients in the Sarcopenia, Suspected-Sarcopenia, and No-Sarcopenia Groups were 31.4, 38.1, and 30.5%, respectively. After controlling for potential confounders, the Sarcopenia Group demonstrated significantly lower step counts than the Suspected-Sarcopenia Group ( = .016) and No-Sarcopenia Group ( = .009).
Our findings indicate that patients with PAD and sarcopenia require rehabilitation strategies to enhance physical performance.
