Incidence And Determinants Of Early Myocardial Infarction Following Percutaneous Coronary Interventions According To The Revised Joint Task Force Definition Of Troponin Ielevation

OBJECTIVE Under the revised definition,Our study investigated the incidence and predictive factors of early PCI associated MI.METHODS We choose randomly 98(from January to April in 2009)patients with coronary heart disease who had elective stent implantation.Incidence of a early PCI associated MI in 8 hour was assessed by analysis of cardiac troponin I(cTn I,troponin I≥0.03ng/ml) before 8h after the intervention.This is based on a TnI cut-point of more than three times the 99th percentile(0.03 ng/ml),We tried to find determinants of early myocardial infarction following percutaneous coronary interventions.Results Early myocardial infarction following percutaneous coronary interventions is 66%.Rises in troponinI were significantly associated with Statin administration that was started at least 3 days before the procedure.Early PCI relevant MI were not associated with the other determines. Conclusions Pre-procedural statin therapy reduces the incidence of early PCI associated MI.This randomized study confirms the cardioprotective effects of statin pre-treatment(≥72h) in patients undergoing elective stent implantation.
