Abstract
BACKGROUND: Previous investigators have observed a doubling of the mortality rate among patients with intermittent claudication, and we have reported a fourfold increase in the overall mortality rate among subjects with large-vessel peripheral arterial disease, as diagnosed by noninvasive testing. In this study, we investigated the association of large-vessel peripheral arterial disease with rates of mortality from all cardiovascular diseases and from coronary heart disease. METHODS: We examined 565 men and women (average age, 66 years) for the presence of large-vessel peripheral arterial disease by means of two noninvasive techniques--measurement of segmental blood pressure and determination of flow velocity by Doppler ultrasound. We identified 67 subjects with the disease (11.9 percent),
