Abstract：Objective To investigate the relationship between ST-segment elevation index(∑STI) and left ventricular function for acute ST-segment elevation myocardial infarction(STEMI) patients. Methods According to the circumstance of ∑STI fall after percutaneous coronary intervention(PCI), 72 acute STEMI patients who had undergone emergency treatment of PCI directly were divided into ST-segment fall group and non-ST-segment fall group. The following items were observed in the two groups, including age, sex, history of smoking, anterior myocardial infarction, history of hyperlipidemia, history of hypertension, history of angina pectoris, CK-MB , history of type 2 diabetes, onset & visiting time, Killip classification, and left ventricular ejection fraction(LVEF) in hospital and 6 months after direct PCI. ResultsNo statistically significant difference in age, sex, infarct sites, history of angina pectoris, CK-MB, Killip classification, etc. was existed between the two groups(P>0.05). However, LVEF of ST-segment fall group in hospital and 6 months after direct PCI were significantly higher than that of non-ST-segment fall group, with statistically significant difference(P<0.05). Conclusion ∑STI has great clinical value in predicting left ventricular function of acute ST-segment elevation myocardial infarction patients.
