Abstract

Introduction: Cardiovascular disease is a public health problem globally. In India, the prevalence of Acute Myocardial Infarction (AMI) was 6.43%. Several causes lead to AMI, among which excess serum Iron and Ferritin is responsible for an increase in the generation of free radicals, thus accelerate atherogenesis through oxidation of Low-density lipoprotein – cholesterol (LDL-C). Assess serum Iron and Ferritin status and compare them with the cardic marker (CK-MB) among patients with AMI. Methods: The study was performed in a tertiary care centre in TamilNadu, India. This casecontrol study was conducted on 25 patients diagnosed with AMI and 25 age and sex-matched healthy participants as control group. Iron, Ferritin, CK-MB and lipid profile parameters were analyzed in serum samples of the participants. Result: The mean levels of serum Iron, Ferritin, CK-MB and lipid profile parameters were increased significantly among the cases when compared to the control group. CK-MB had a strong positive correlation with serum Iron and Ferritin. Serum Iron and Ferritin also had a positive correlation with total cholesterol and LDL-C, and a negative correlation with Highdensity lipoprotein – cholesterol. The odds of developing AMI in those with serum Iron >51.5µg/dl and Ferritin >137ng/dl were 36 and 61.7 times at higher risk respectively. Conclusion: Higher levels of serum Iron and Ferritin seem to be stronger risk factors for AMI, and shall be considered as early screening cardiac markers for AMI.
