Estimating the Correlation of Ankle Brachial Index with Vascular Risk Factors in Pre-diabetics

Background: Prediabetes is characterized by a long duration of insulin resistance and increased fasting plasma glucose. Among the various risk factors for cardiovascular atherosclerosis and prediabetes, insulin resistance is one of them. Glycemia has been recognized to affect microvascular damage as compared to macrovascular damage. The ankle-brachial index (ABI) is a simple, affordable and non-invasive test as compared to angiography and has been found to have a high sensitivity and accuracy for the diagnosis of PAD, the gold-standard diagnostic method. This index is based on the fact that in healthy people, systolic blood pressure in the legs is typically equal to or marginally greater than in the upper limbs. This study aims to assess the correlation of ABI with vascular risk factors among subjects with Prediabetes like anthropometric measurement like BMI, Waist hip ratio and neck circumference.

Methods: This will be a observational cross sectional study. The present research will involve a cluster of prediabetic subjects. ABI will be determined for all patients. Anthropometric measurements will be taken and blood investigations will be conducted. All data will be compiled and analyzed with appropriate statistical tests.

Expected Results: We expect a significant association between prevalence of low ABI in prediabetics and heart problems.

Conclusion: This research will highlight the adequate clinical and sociological assessment of pre-diabetes patients, including those who have been diagnosed for a long period of time.
