OBJECTIVES: Little is known about whether estimated glomerular filtration rates (eGFR) affect left ventricular (LV) function and gain benefit with antiremodeling treatment in patients with ST-elevation myocardial infarction (STEMI). We investigated the effect of eGFR on LV function using tissue Doppler imaging (TDI) parameters. In addition, we sought to evaluate the antiremodeling effect of standard treatment at follow-up in patients with renal insufficiency (RI) after STEMI. METHODS AND RESULTS: A retrospective analysis of 579 patients with STEMI was performed. Patients were divided into 3 groups according to eGFR (Group 1: eGFR > 90 mL/min per 1.73 m(2); Group 2: eGFR = 60-89 mL/min per 1.73 m(2); Group 3: eGFR < 60 mL/min per 1.73 m(2)). Conventional echocardiography and TDI were performed within 48-72 hours after STEMI and at 6-month follow-up. The mean left ventricular ejection fraction (LVEF) was significantly lower in Group 3 than in Group 1 (P = 0.021). The mean peak systolic velocity (Sm) was significantly lower in Group 3 than in Group 1 and Group 2 (P = 0.002 and 0.006, respectively). The estimated GFR had a linear association with Sm and LVEF (P = 0.001, r = 0.161; P = 0.005, r = 0.132, respectively). Multivariate analysis showed that an eGFR < 60 mL/min per 1.73 m(2) was an independent predictor of lower Sm and in-hospital mortality. In addition, an antiremodeling effect of standard treatment was seen in all groups at 6-month follow-up. CONCLUSIONS: Estimated glomerular filtration rate of <60 mL/min per 1.73 m(2) was associated with lower LV function after STEMI, and may gain an antiremodeling effect with standard treatment at follow-up.
