Abstract

We have evaluated in a case-control study the association of the main risk factors with cerebrovascular ischemic accidents in elderly patients. Two hundred and twenty patients aged 65 year or more (average age 77.3 +/- 7.3 yr, 93 males and 127 females) admitted to our Division for stroke (122) or transient ischemic attacks (TIA) (98) were enrolled: 220 hospitalized patients, age and sex-matched, without actual or previous cardiovascular clinical manifestations were the control group. Advanced senile decay, hepatic or renale failure and malignancies were considered exclusion criteria for both groups. The following risk factors have been considered: family history, obesity, cigarette smoking, diabetes, hypercholesterolemia, hypertriglyceridemia, atrial fibrillation, left ventricular hypertrophy, and related continuous variables. After logistic multiple regression analysis, atrial fibrillation, hypertension and blood cholesterol concentration above 240 mg/dl were significantly and independently associated with stroke, while only hypertension and hypercholesterolemia were associated with TIA. The unexpected finding of a significant association between hypercholesterolemia and cerebrovascular ischemia seems attributable to the choice of hospitalized patients as control group. These results indicate that hypertension and atrial fibrillation are independently associated with ischemic stroke even in advanced age.
