CORRELATION BETWEEN INSULIN RESISTANCE AND SEVERITY OF CORONARY ARTERY DISEASE IN NON-DIABETES

Objective: There is an increased risk of CAD in both diabetes and non-diabetes. Insulin resistance has been associated with development of CAD in this both populations. However, there are not many studies on correlation between insulin resistance and severity of CAD in non-diabetes. The present study aimed to establish a correlation between insulin resistance and severity of CAD in non-diabetic individuals.Methods: A cross-sectional study of 79 consecutive Non-diabetic patients undergoing coronary angiogram for evaluation of clinically suspected coronary artery disease at a tertiary care hospital in Mangalore, Karnataka were recruited. Clinical history, anthropometric and biochemical parameters were analyzed. Insulin resistance was determined by Homeostasis model assessment (HOMA-IR). The severity of CAD was assessed by modified Gensini score. Pearson correlation was done to find out the relation between HOMA-IR and Gensini core.Results: The correlation between log of HOMA-IR and severity of coronary artery disease as assessed by Gensini score (r = -0.053 and p= 0.64) was not significant in non-diabetic patients. The correlations between severity of coronary artery disease and other known risk factors of coronary artery disease were also was not significant.Conclusion: HOMA-IR is negatively associated with severity of CAD in non-diabetes.
