[Risk factors and multicentricity of vascular atherosclerotic disease. Our experience].

The objective of this study is the identification of the most important risk factors of atherosclerosis and the determination of its multicentricity, the goal being an efficient primary and secondary prevention of this disease. Over the course of eight years, at the Department of Diagnosis and Surgical Physiopathology of Peripheral Vascular Diseases, 829 subjects with atherosclerosis were examined, of whom 513 males and 316 females between 18 and 85 years old, as well as to 200 healthy control subjects. The risk factors in consideration were: age, sex, hypertension, diabetes, lipoidoproteinosis, smoking, alcohol and coffee intake. From the data obtained it was revealed that smoking represents the most important risk factor for atherosclerosis (65% of the cases, 40% of the controls), followed in decreasing order by hypertension (31% of the cases, 6% of the controls), diabetes (26% of the cases, 2% of the controls), lipoidoproteinosis (15% of the cases, 6% of the controls). Furthermore 21% of the subjects drank coffee and 28% ingested alcoholic beverages, compared with, respectively 19% and 24% of the controls. In 70% of the cases the presence of atherosclerotic lesions were found in more than one vascular region. Atherosclerosis has a multifactorial etiology as there exists a correlation between the predisposition of the patient to acquire the disease and environmental factors. It is difficult to distinguish the determining effects of a single risk factor, because often many risk factors are tightly interrelated in the same individual; a nearly direct relationship clearly exists between the number and entity of the risk factors and the clinical picture of the patient examined.(ABSTRACT TRUNCATED AT 250 WORDS)
