[Risk factors in various groups of stroke patients (Analysis of 500 cases of the Budapest Stroke Database)].

Risk factor profile of 500 consecutive acute++ stroke cases in the protocol of the Budapest Stroke Data Bank has been analysed. High frequency of risk factors and additive occurrence have been documented when compared with other stroke registries; hypertension 75%, hypercholesterolemia 68%, ischemic heart disease 61%, hypertriglycerolemia 39%, smoking 38%, serious hypercholesterolemia 36%, diabetes mellitus 30%, peripheral artery disease 10%, elevated hematocrit 7% and elevated number of platelets 7%. More than one risk factors have been registered in 85% of the patients. Three risk factors at the same patient have been found in 28%. The highest number of risk factors is seven at the same patient. The stroke subtypes have been characterized with "cluster-like" association of risk factors. In the hemorrhagic group (9.4% of all cases) hypertension and alcoholism are the main factors; in the atherosclerotic group (49.4%) more male, smoking peripheral artery disease and hypercholesterolemia have been registered; in the lacunar stroke group (27%) high frequency of hypertension, smoking, diabetes mellitus, hypercholesterolemia and hypertriglycerolemia have been found and in the cardiogenic embolia group (10.6%) more female, higher age, ischemic heart disease and atrial fibrillation are the recurrent risk factors. There is no difference between the risk factor profile++ registered in the left versus right hemispheral strokes, in the anterior versus posterior strokes and in the first ever or recurrent strokes.
