BACKGROUND: The main cause of atherosclerotic peripheral vascular disease is known to be atherosclerotic processing. In patients with atherosclerotic peripheral vascular disease, other atherosclerotic diseases are frequently combined, especially coronary artery disease. There were some suggestions that the risk factors of the atherosclerotic peripheral vascular disease be different from the those of the coronary artery disease. The aim of this study was to evaluate the independent risk factors for the atheroslerotic peripheral vascular disease(PVD) without influence of coronary artery disease(CAD). METHODS: The study population was male patients with atherosclerotic peripheral vascular disease(n=66) documented by peripheral angiogram form February 1991 to Octobor 1993, and during their abmission all patients with suspected atherosclerotic peripheral vascular diaease underwent both peripheral angiogram and coronary angiogram. Careful history taking and physical examination and lipid battery sampling after at least 14 hours of fasting were also performed. RESULTS: 60% of patients with peripheral vascular disease also had coronary artery disease. There was no significant difference in total cholesterol, HDL cholesterol, LDL cholestrerol, triglyceride between patients with peripheral vascular disease and age-matched control. The prevalence of hypertension was higher in patients with peripheral vascular disease but with no statistical significance. Smoking(p<0.0001) and diabetes(p<0.05) were strongly associated with peripheral vascular disease. When patients without coronary artery disease were compared to control from the viewpoint of risk factors again, the results were the same, that is, smoking and diabetes were also associated with periperal vascular diseaes. CONCLUSION: The prevalence of associated coronary artery disease was relatively high in patients with atherosclerotic peripheral vascular disease. And smoking and diabetes seem to be important risk factors of atherosclerotic peripheral vascular disease.
