Cerebral Infarction and Asymptomatic Arteriosclerosis Obliterans in the Elderly

We examined the associations between cerebral infarction (CI), asymptomatic arteriosclerosis obliterans (ASO), and known risk factors for these diseases. The subjects were 67 elderly patients (11 men and 56 women, mean±SD age of 79.6±8.5 years). in 44 patients CI was diagnosed by CT scan; 23 were classified as having cortical infarction and 21 as having lacunar infarction. In 41 patients asymptomatic ASO was diagnosed by an ankle-pressure index (API) of less than 0.9. To identify risk factors for these diseases, we examined the association among these diseases and hypertension (blood pressure≥140/90mmHg), hypercholesterolemia (total cholesterol concentration≥220mg/dl), hypertriglyceridemia (triglyceride concentration≥150mg/dl), low HDL-cholesterolemia (HDL-C concentration
