The effect of early invasive strategy on mortality outcome in patients with chronic kidney disease presenting with non-ST segment elevation myocardial infarction

Background Current guidelines recommend an early invasive strategy for patients with non-ST segment elevation myocardial infarction (NSTEMI). Purpose To evaluate whether early invasive strategy is associated with better outcome among patients with chronic kidney disease (CKD). Methods Retrospective cohort analysis of consecutive patients with NSTEMI between 2008 and 2021. Glomerular filtration rate (eGFR) was estimated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation. Invasively treated patients were dichotomized into early ( Results Final study population comprised 7,107 NSTEMI patients, of whom 3,172 (45%) had eGFR Conclusion Among invasively treated NSTEMI patients, the benefit of early invasive strategy is modified by CKD, and limited to those with eGFR ≥45 ml/min/1.73m2.
