ABSTRACT
Background: Cardiovascular risk factors for ACS are on the rise in people of Indian origin and ACS is now the leading cause of death. More recent evidence suggests that bilirubin is a potent physiological antioxidant that may provide important protection against atherosclerosis and inflammation. Substantial evidence has documented that the development of CAD involves lipid oxidation and formation of oxygen radicals as atherosclerosis and inflammation are associated with formation of oxygen and peroxyl radicals. Keep of these points in mind, the present study was undertaken to find relation between Serum Bilirubin and Acute Coronary Syndrome.Methods: The present descriptive cross-sectional study conducted at A.J Institute of Medical Sciences and Research Centre, Mangaluru from October 2016 to April 2017. A detailed history, general physical examination, systemic examination and investigations was performed on all patients who fulfill the inclusion criterion and age >18yrs, both sexes who are admitted in CCU.Results: Hypertension had statistically significant correlation with ACS. All risk factors were more associated with STEMI compared to unstable angina or NSTEMI. On Correlation of LDL and Total leucocyte count with bilirubin both were statistically significant when compared to bilirubin levels.Conclusions: The study showed an inverse correlation of bilirubin with ACS, which in shows fact that bilirubin acts as an antioxidant and has cardioprotective action and patients with ACS have lower levels of bilirubin. This can use as a factor for screening individuals who have high risk for ACS and preventive strategies applied in them before the onset of overt ACS.
