Peripheral artery disease in type II diabetes

ABSTRACT

To determine the frequency of peripheral arterial disease [PAD] in type 2 diabetic patients. Cross-sectional observational study. Diabetes Clinic, Medical Unit III, Jinnah Postgraduate Medical Centre, Karachi, from January to June 2010. Three hundred and eighty seven [387] type II diabetic patients of either gender and any age were included in the study. Patients with a previous history of trauma to the arterial vasculature, pregnancy and those who underwent arterial graft procedures were excluded. Non-purposive convenient sampling technique was used to enroll patients in the study. PAD was diagnosed when ankle-brachial index [ABI] was less than 0.9. A p-value of less than 0.05 was considered statistically significant. Out of 387 studied patients, 128 were males [33.1%] and 259 were females [66.9%]. Mean age was 52.22 +/- 9.671 [22 -76] years in the entire cohort. Mean duration of diabetes was 9.38 +/- 6.39 years. PAD was detected in 152 [39.28%] of the total study subjects. Thirty-one of 128 male patients [24.22%] had PAD disease while 121 out of 259 female patients [46.71%] had evidence of PAD [p = 0.001]. Hypertension was a significantly associated factor [p = 0.002]. A high frequency of PAD was observed in the diabetic population particularly with hypertension and more prevalent in females
