The circulating levels of miR-133a can be used as a predictor for diagnosing AMI and coronary heart disease (CHD), since its levels 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 CHD patients [115]. Here, TNNT2 is linked to coronary artery disorder.
