Prevalence of Peripheral Arterial Disease in a Cohort of Diabetic Patients
Abstract
Background:The aim of this study was to determine the prevalence of peripheral diseases in diabetics of different age groups, the role of color Doppler in peripheral arterial disease in diabetics, and to compare the prevalence of peripheral arterial disease (PAD) in diabetics taking different therapy modalities. Methods:In a hospital-based prospective study conducted over 19 months, we screened 100 consecutive type 2 diabetic patients and 50 consecutive nondiabetic patients matched for demographics and ethnicity. History, physical examination and color Doppler results were analyzed. The degree of stenosis in PAD was graded according to Jager's criteria. Result:The prevalence of PAD was 8% in controls and 24% in diabetics. There were 60 subjects (60%) greater than 50 years of age in the diabetic population and 36 (72%) subjects in the nondiabetic group. There was male preponderance with 70% of diabetic patients and 60% of nondiabetic patients being male. According to mode of therapy, the prevalence of PAD was found to be 20% in diabetics taking oral hypoglycemic agents and insulin, 27.2% on oral hypoglycemic agents, and 25% on insulin therapy. Conclusion:This study suggests that there is a higher prevalence of PAD in diabetics as compared with controls. The prevalence of PAD is directly proportional to the duration of diabetes and age of the person. The prevalence of PAD is not a function of treatment modality. The stenosis associated with PAD in diabetics is generally infrapopliteal.This content is limited to qualifying members.
