Arteriosclerosis Obliterans: Review of 520 Cases with Special Reference to Pathogenic and Prognostic Factors

Abstract

The clinical and follow-up data on 520 non-diabetic patients less than 60 years of age who had a clinical diagnosis of arteriosclerosis obliterans of the lower extremities made at the Mayo Clinic in the period 1939 through 1948 were reviewed from the standpoint of pathogenesis, prognosis, and clinical course of the disease. The ratio of males to females was 11 to 1, and the mean concentration of plasma cholesterol in the male patients with arteriosclerosis obliterans was approximately 50 mg. per 100 ml. greater than that of either of 2 control groups of men without clinical evidence of atherosclerosis. The incidence of smoking among the men with this disease was higher than in a comparable group of men without it. Obesity was not commonly associated with arteriosclerosis obliterans, while hypertension was associated with the disease about 3 times as often as in a control group without the disease.
