Abstract
Objective To explore the value of terminal T wave inversion (TTWI) on predicting short-term prognosis of patients with acute ST-elevation myocardial infarction (STEMI) undergoing urgent percutaneous coronary intervention (PCI). Methods We carried out this study in 145 STEMI inpatients undergoing urgent PCI in Yangpu Hospital,Tongji University from September 2014 to November 2015.Electrocardiogram (ECG) was performed in all the patients immediately after admission and at 24 hours after urgent PCI.The patients were divided into three groups according to the status of T wave: normal T wave group (T wave completely restored upright,n=69),shallow inversion of the T wave group (biphasic inversion of T waves <2 mm,n=33),deep inversion of the T wave group (including completely inverted T wave and/or biphasic inversion of T waves≥2 mm,n=43). The baseline data,value of left ventricular ejection fraction (LVEF) by UCG before discharge and major adverse cardiac events (MACE) occurred in 1-year follow-up period were recorded.Results The incidence of anterior wall myocardial infarction was lower in the normal T wave group than in the other two groups (P<0.01).Patients in normal T wave group had higher average values of LVEF measured before discharge than those in the deep inversion of the T wave group (P<0.05).Patients in normal T wave group were found to have less MACE than those in the deep inversion of the T wave group in the 1-year follow-up period (P<0.01).Multivariate Logistic regression analysis showed that Killip classⅢ-Ⅳ,anterior wall myocardial infarction,and status of TTWI were influence factors of MACE occurred in 1-year follow-up period (P<0.05).Conclusion This study showed that TTWI is closely correlated with the value of LVEF before discharge and incidence of MACE in 1-year follow-up period;Killip classⅢ-Ⅳ,anterior wall myocardial infarction and TTWI are influence factors for the incidence of MACE in 1-year follow-up period.关键词
