背景
Troponin I (TnI), along with troponin T (TnT) and troponin C (TnC), is one of 3 subunits that
form the troponin complex of the thin filaments of striated muscle. TnI is the inhibitory
subunit; blocking actin-myosin interactions and thereby mediating striated muscle
relaxation. The TnI subfamily contains three genes: TnI-skeletal-fast-twitch, TnI-skeletalslow-twitch, and TnI-cardiac. This gene encodes the TnI-cardiac protein and is exclusively
expressed in cardiac muscle tissues. Mutations in this gene cause familial hypertrophic
cardiomyopathy type 7 (CMH7) and familial restrictive cardiomyopathy (RCM). Troponin I is
useful in making a diagnosis of heart failure, and of ischemic heart disease. An elevated
level of troponin is also now used as indicator of acute myocardial injury in patients
hospitalized with moderate/severe Coronavirus Disease 2019 (COVID-19). Such elevation has
also been associated with higher risk of mortality in cardiovascular disease patients
hospitalized due to COVID-19.
