Prevalence of peripheral arterial disease among type 2 diabetes mellitus in coastal Karnataka

Peripheral Arterial Disease (PAD) is one of the leading complications of Type 2 Diabetes Mellitus (T2DM). According to American Heart Association, PAD is defined as, "a narrowing of peripheral arteries to the legs, stomach, arms and the head-most commonly the arteries of leg." The global prevalence for PAD with age adjusted prevalence is approximately 12%, and it affects relatively 8 to 12 million British people. The prevalence of PAD is 2-3 times higher in person with v/s without type 2 diabetes mellitus (T2DM). Various subjective and objective methods are available to diagnose PAD, which includes questionnaires for pain and quality of life as subjective and Ankle Brachial Index (ABI), toe brachial index (TBI), arterial doppler for objective. ABI is one of the most reliable and easy to carry out method in clinical setups to diagnose PAD. The normal range for ABI is 0.9-1.29, 0.91 to 0.99 are considered as borderline, 0.41 to 0.91 are considered as mild to moderate diseased and below 0.4 is severe PAD. The objective of the study is to estimate the prevalence of peripheral arterial disease with type 2 diabetes mellitus in coastal Karnataka. Methodology: A total of 317 participants were recruited for the study based on inclusion criteria. Ethical clearance was taken from the Institutional Ethics Committee. Participants were explained about the study and informed consent was obtained from the participants. Inclusion criteria was any individual with T2DM on medication. A subjective questionnaire specific to PAD was administered to the participants. Along with this the objective measure, ABI was done on the individuals. Result: The mean age of all the participants was 57.36 +/- 10.43 in years. The average Body Mass Index (BMI) was 24.62 +/- 11.80 in Kg/m2. The mean duration of diabetes was found to be 9.13 +/- 6.56 in years. The prevalence of peripheral arterial disease was found to be 8.52% in the study population. Conclusion: The prevalence of peripheral arterial disease was found to be 8.52% in the study population. (c) 2019 Diabetes India. Published by Elsevier Ltd. All rights reserved.
