Myocardial infarction occurs due to ischemia and necrosis of cardiac muscle, leading to the release of intracellular substances into the blood. These substances are known as cardiac biomarkers. While cardiac dysfunction includes many conditions, this lecture focuses specifically on biomarkers useful for diagnosing MI. Classic enzyme markers include CK-MB, AST, and LDH. CK-MB is relatively cardiac-specific and rises within 3–6 hours, peaks at 18–24 hours, and normalizes in 2–3 days, making it useful for early diagnosis and infarct size estimation. AST is less specific but has strong prognostic significance, while LDH is a late marker showing the classical LDH-1 more than LDH-2 flipped pattern in MI. Among non-enzyme markers, cardiac troponins (cTnI and cTnT) are the gold standard due to their high cardiac specificity. Troponins rise early and remain elevated for 7–14 days, allowing diagnosis even in late presenters. Myoglobin, though highly non-specific, is the earliest marker to rise, making it useful for very early detection. This lecture integrates graphs, timelines, and exam-friendly explanations, helping students remember and apply cardiac biomarkers confidently in theory exams, viva, and clinical settings.
