ABSTRACT

Objective To study the the association of Hs-cTNT level with coronary flow in patients with ST-segment elevation myocardial infarction(STEMI) undergoing percutaneous coronary intervention(PCI).Methods130 cases with STEMI in hospital from January 2014 to December 2014 were divided into the positive group and the negative group according the level of Hs-cTNT.Multivariate analysis were used to examine the association of Hs-cTNT with coronary flow in patients with ST-Segment elevation myocardial infarction undergoing primary PCI.ResultsThe incidence of no reflow in the positive group was significantly higher than that in the negative group (P<0.05) The left ventricular ejection fraction in the positive group was significantly lower than that in the negative group (P<0.05).Multivariate analysis showed that Hs-cTNT was independently associated with coronary flow no-reflow in patients with acute STEMI post-PCI and TIMI flow fractionation events(P<0.05).ConclusionHypersensitivity troponin T is an effective marker for predicting coronary artery flow damage in patients with STEMI after PCI and evaluating risk stratification in patients with STEMI.
