Which test is a marker for ischemic heart disease?

• A. C-reactive protein
• B. Albumin cobalt binding
• C. Troponin I
• D. Creatinine kinase

Answer: (C)

Troponin I is a highly specific marker for ischemic heart disease, particularly in the context of myocardial injury such as in acute myocardial infarction. It is a protein found in cardiac muscle that is released into the bloodstream when the heart muscle is damaged. The presence of elevated troponin I levels indicates myocardial cell necrosis, making it a critical biomarker for diagnosing acute coronary syndromes and assessing the severity of ischemic heart disease. Timely measurement of troponin I levels assists healthcare professionals in ruling in or ruling out cardiac events, which is essential for patient management and treatment decisions in cases of chest pain or suspected heart issues. While other tests, such as C-reactive protein, albumin cobalt binding, and creatinine kinase, may have relevance in different contexts of cardiovascular disease or general health assessment, they are not as specific for ischemic heart disease as troponin I. C-reactive protein is more of a general inflammation marker, albumin cobalt binding is less commonly used and relates to other conditions, and creatinine kinase, although involved in muscle damage assessment, is less specific to cardiac tissues compared to troponin I.
