Authors' objectives: For patients with peripheral artery disease (PAD), the optimal treatment for cardiovascular protection, symptom relief, preservation of walking and functional status, and prevention of amputation is not known. This review assessed the comparative effectiveness of antiplatelet therapy, medical therapy, exercise, and endovascular and surgical revascularization in PAD patients with intermittent claudication (IC) or critical limb ischemia (CLI).
Authors' recommendations: From a limited number of studies, it appears that aspirin has no benefit over placebo in the asymptomatic PAD patient; clopidogrel monotherapy is more beneficial than aspirin in the IC patient; and DAPT is not significantly better than aspirin at reducing cardiovascular events in patients with IC or CLI. For IC patients, exercise therapy, cilostazol, and endovascular intervention all had an effect on improving functional status and quality of life; the impact of these therapies on cardiovascular events and mortality is uncertain. The comparisons of endovascular and surgical revascularization in CLI are primarily from observational studies, and the heterogeneity of the results makes conclusions for all clinical outcomes less certain. Several advances in care in both medical therapy and invasive therapy have not been rigorously tested and thus provide an impetus for further research.
