Inflammation is known to be the root cause of the development of coronary artery disease (CAD). Subclinical inflammation is one of the key players in pathophysiology of CAD. An inflammatory response leads to the secretion of various adipokines and cytokines. There are various pro-inflammatory markers which could be used to determine the onset of disease, and one such marker is resistin adipokine. The present study evaluates and compares the circulatory concentration of resistin in CAD patients and controls for the determination of its association with CAD. In this study, 58 CAD patients were enrolled and were further subdivided into four groups as per the associated co-morbidities. Various anthropometric and biochemical parameters were assessed. The circulatory levels of resistin were found to be significantly elevated in CAD patients and their subgroups as compared to controls. We conclude that elevated resistin levels in CAD patients suggest a key role of resistin in the development of CAD. The present study also observed that co-morbidities like type 2 diabetes can act as one of the major factors for the elevated concentration of resistin in the circulation of CAD patients with diabetes.
