Cardiac Markers

Cardiac disorders involve diverse abnormalities in myocardial function and circulation and key biomarkers aid in their rapid assessment. Myoglobin and CK-MB indicate early myocardial injury, while cardiac troponin I offers the highest specificity for myocardial infarction. BNP reflects ventricular stress and is crucial in diagnosing heart failure. D-dimer helps identify thrombotic events such as pulmonary embolism and homocysteine serves as a marker of endothelial dysfunction and cardiovascular risk. Collectively, these markers enhance diagnosis and risk stratification in cardiac conditions.
