ABSTRACT

Objective: To determine the frequency of peripheral artery disease (PAD) in diabetic patients by assessing ankle brachial index (ABI).

Study Design: Cross-sectional study

Place and Duration of Study: This study was conducted in the Department of Medicine, Abbasi Shaheed Hospital for a period of six month from September 2011 to March 2012.

Materials and Methods: All type 2 diabetics of more than two years disease duration, on treatment, of either gender, were included between 41 years to 70 years of ages. Peripheral artery disease was assessed by ankle brachial index (ABI). Frequency and percentages were presented for gender, smoking status, family history of type 2 diabetes and PAD. Mean and standard deviation was presented for age of patients, duration of diabetes and smoking status.Chi square test was used to compare relative frequencies.

Results: A total of 125 patients were included with a mean age of 57.10 + 8.77 years. 68 (54.4%) were female. Mean duration of diabetes was 4.62 + 2.21 years. PAD was found in 74 (59.2%) while 51 (40.8%) patients were free from PAD.

Conclusion: A high frequency of PAD was detected in the diabetic subjects with a female pre-ponderance, with statistically significant association with increasing age, hypertension and duration of diabetes. Key Words: Peripheral artery disease, ankle brachial index, diabetes mellitus
