Prevalence and Prognostic Implications of Worsening Renal Function After Acute Myocardial Infarction

초록

We sought to investigate the relation between worsening renal function (WRF) at 1-year follow-up and clinical outcomes at 3 years after acute myocardial infarction (AMI). We 2011 to December 2015. Patients with all-cause death, recurrent myocardial infarction (re-MI), and rehospitalization for heart failure at 1-year follow-up after AMI were excluded. A total of 6,235 patients were extracted and divided into WRF and non-WRF groups. WRF was defined as a & GE;25% decrease in estimated glomerular filtration rate (eGFR) from baseline to 1-year follow-up. The primary outcome was 3-year major adverse cardiac events, a composite of all-cause death, re-MI, and rehospitalization for heart failure. On average, a -1.5 ml/min/1.73 m2/y rate of decrease in eGFR was exhibited, and 575 patients (9.2%) exhibited WRF at 1-year follow-up. After multiple adjustments, WRF at 1-year follow-up was independently associated with increased risks of major adverse cardiac events (adjusted hazard ratio 1.498, 95% confidence interval 1.113 to 2.016, p = 0.01), all-cause death, and re-MI at 3-year follow-up. Older age, female, diaventricular ejection fraction <35%, and baseline eGFR <30 ml/min/1.73 m2 were identified as independent predictors of WRF after AMI. In conclusion, WRF at 1-year follow-up after AMI intuitively seems like a risk marker indicating multiple co-morbidities. Monitoring serum creatinine in patients at 1-year follow-up after AMI may help to identify those who are at the highest risk and guide effective long-term therapeutics.& COPY; 2023 Elsevier Inc.
