Article
Research record from PLoS One, 2026-04-08. PMID 41950232.
Indicators
Proteins released into blood when heart muscle is injured; the central laboratory marker in suspected heart attack.
Tests
Blood proteins released when heart muscle is injured; the primary laboratory marker in the evaluation of possible acute myocardial infarction.
Tests
This test measures the amount of creatine kinase (CK) in a sample of your blood. CK is also called creatine phosphokinase (CPK).
Tests
A chemiluminescence immunoassay capable of detecting very low levels of troponin T in serum.
Indicators
Troponin I, troponin T, and troponin C are the three closely associated subunits of the troponin complex of thin filaments in muscle. The complex serves as a calcium-sensitive switch that regulates muscle contraction. In the absence of calcium, Troponin I binds actin, inhibits actomyosin ATPase activity, and inhibits F-actin-myosin interactions. The troponin I gene family comprises three isoforms: skeletal TNI-fast, skeletal TNI-slow, and TNI-cardiac. (from OMIM 191044, 191043, 191042 and NCI)
