Cardiac biomarkers are the enzymes released into the blood when the heart experiences any discomfort or defects, such as stress or impairments. The quantity of cardio enzymes in the blood can be utilized to detect heart diseases, especially acute coronary syndrome (ACS) and cardiac ischemia. The test is done by taking a sample of the patient’s blood and analyzing it to measure the level of cardiac biomarkers in their blood. It can detect low oxygen intake conditions or injuries in the heart. Myoglobin, troponin, and creatine kinase are the three cardiac biomarkers or enzymes. Among these, the most commonly used cardiac biomarker is troponin due to its highest sensitivity [3]. Usually, the quantity of cardiac markers in the blood is measured in nanogram/milliliter (ng/ml) units. The normal measure of troponin in the blood ranges from 0 to 0.4 ng/ml. The high-sensitivity troponin test can detect a very small level of troponin. The normal range value is 14 ng/l for troponin during cardiac biomarker examination (high-sensitivy troponin test). Anything above 14 ng/l is considered abnormal.
