Acute myocardial infarction, the major cause of death in developed countries is becoming more prevalent in developing countries due to rapid urbanization and change to western life style. Myocardial infarction occurs due to occlusion of the coronary artery leading to myocardial necrosis, heart failure and arrhythmias, causing an increase in morbidity. Early recognition of acute myocardial infarction (AMI) leads to early treatment by means of thrombolysis, percutaneous intervention or coronary artery bypass surgery leading to decrease in the size of infarct and thereby reducing the complications of AMI. This article would focus on the currently used cardiac biomarkers for acute myocardial infarction and emerging role of high sensitive troponin in future and clinical usefulness of creatine kinase MB isoform.
Keywords: Cardiac biomarker, Troponin, High sensitive troponin, Creatine kinase MB (CK MB), Multi marker testing.
