Abstract

Background and aims: Because of paucity of published data, we evaluated the 2-year major clinical outcomes between early invasive (EI) and delayed invasive (DI) strategies according to the stage of chronic kidney disease (CKD) in patients with non-ST-segment elevation myocardial infarction (NSTEMI), who underwent a successful newer-generation drug-eluting stent (DES) implantation. Methods: A total of 8241 NSTEMI patients were recruited from the Korea Acute Myocardial Infarction Registry (KAMIR). Based on baseline estimated glomerular filtration rate (eGFR; ≥90, 60–89, 30–59, and <30 mL/min/1.73 m2), the patients were classified into groups A (n = 3498), B (n = 3109), C (n = 1178), and D (n = 1178). Thereafter, these 4 groups were sub-classified into the EI and DI groups. Major adverse cardiac events (MACE), defined as all-cause death, recurrent MI (re-MI), and any repeat revascularization, were evaluated. Results: After multivariable-adjusted and propensity score-adjusted analyses, the cumulative incidence of MACE (group A, p = 0.139 and p = 0.103, respectively; group B, p = 0.968 and p = 0.608, respectively; group C, p = 0.111 and p = 0.196, respectively; group D, p = 0.882 and p = 0.571, respectively), all-cause death, re-MI, and any repeat revascularization was similar between the EI and DI groups in the 4 different renal function groups. Conclusions: In the era of newer-generation DES, EI and DI strategies showed comparable major clinical outcomes in patients with NSTEMI and CKD during a 2-year follow-up period. However, to confirm these results, further randomized, large-scale, long-term follow-up studies are needed.
