Estimated glomerular filtration rate(eGFR) is significantly reduced in patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study is to research that the incidence of adverse cardiovascular events (MACE) in patients with ST-segment elevation myocardial infarction is significantly higher when the glomerular filtration rate below a certain value.

The investigators retrospectively analyzed the clinical data of 1157 patients with ST-segment elevation myocardial infarction. In-hospital adverse cardiovascular events (MACE) was defined as: cardiac arrest, cardiac rupture, malignant arrhythmia, and cardiac death. All the patients were divided into 3 groups according to the patient's estimated glomerular filtration rate(eGFR) (eGFR≥90ml/min/1.73m2; 90ml/min/1.73m2>eGFR≥60ml/min/1.73m2; eGFR<60ml/min /1.73m2). COX regression analysis and K-M survival curves are used to calculate the correlation between eGFR and in-hospital MACE.
