TNNT2 and coronary artery disorder: Since the circulating levels of miR-133a increased in a time-dependent manner in the early phase of AMI and were positively correlated with cTnT in AMI patients, associating miR-133a with the occurrence and severity of coronary atherosclerosis in coronary heart disease (CHD) patients, it can be used as a predictor for diagnosing AMI and CHD [56].
