In a patient at risk of arteriopathy, I find a low ABI but no intermittent claudication or trophic disorder. What should I do?
According to recent epidemiological data, patients with a low ABI (<0.90) and without any symptom have the same cardiovascular risk as those with an intermittent claudication (Hooi JD, Kester AD, Stoffers HE, et al. Asymptomatic peripheral arterial occlusive disease predicted cardiovascular morbidity and mortality in a 7-year follow-up study. J Clin Epidemiol. 2004 Mar;57(3):294-300).
