Cardiac Troponin I (cTnI) is a highly specific and sensitive biomarker for myocardial cell injury. Troponin is a regulatory protein complex involved in muscle contraction, consisting of three subunits—T, I, and C. The cardiac-specific Troponin I isoform, distinct from skeletal muscle forms, serves as a critical diagnostic marker due to its specificity to myocardial tissue and prolonged elevation following cardiac injury.
