Correlation of left ventricular ejection fraction with cardiac troponin I and serum ferritin levels in acute ST elevation myocardial infarction patients.

India has the highest burden of Acute Coronary Syndrome (ACS) patients in the world. Indian Patients who suffer from ACS are relatively younger and have a  significantly higher proportion  of ST-elevation myocardial infarction (STEMI) as compared to patients in developed countries. It is estimated that more than 3 million STEMI occurs every year in India. The measurement of left ventricular ejection fraction (LVEF) after acute myocardial infarction (AMI) is a class I clinical practice guideline recommendation, and  has both prognostic and therapeutic implications. Reduced LVEF is associated with greater mortality in patients with coronary artery disease and predicts increased risks of early mortality, as well as sudden cardiac death. Serum ferritin is an acute phase reactant and is considered to be a risk factor for MI. High serum ferritin may increase the risk of MI in the presence of other risk factors that increase the formation of free radicals, thus accelerating atherogenesis through stimulation of low-density lipoprotein oxidation. So, the aim of the study is to find the correlation of troponin I and ferritin levels with left ventricular ejection fraction in ST elevation MI patients presenting to the hospital.
