title: Effect of in-hospital physical activity on cardiovascular prognosis in lower extremity bypass for claudication.
abstract: [Purpose] This study aimed to evaluate the effect of in-hospital physical activity on patient prognosis after lower extremity bypass surgery for peripheral arterial disease. [Subjects and Methods] A total of 13 patients (16 limbs; 11 males and 2 females; mean age [standard deviation], 72.8 [5.9] years) who underwent lower extremity bypass surgery for Fontaine stage 2 peripheral arterial disease were included in this study and assigned to either an active group (n = 6) to perform increased physical activity after surgery or an inactive group (n = 7) to perform decreased physical activity after surgery. Daily in-hospital physical activity levels were measured continuously with a triaxial accelerometer. The occurrence of adverse cardiovascular events within a 2 year follow-up period was compared between groups. [Results] At discharge, the patients in the active group were able to walk more steps daily than those in the inactive group. The incidence of adverse events was 16.7% in the active group and 71.4% in the inactive group. [Conclusion] A higher in-hospital physical activity level was associated with a better long-term prognosis after lower extremity bypass surgery in patients with peripheral arterial disease.
