Abstract

BACKGROUND AND AIMS: The association between implanted stent types and heart failure in patients with non-ST-elevation myocardial infarction (NSTEMI) remains unknown. The current study aimed to investigate whether the implantation of a newer-generation drug-eluting stent (NG-DES) compared with that of a bare-metal stent (BMS) in patients with NSTEMI who receive an undefined duration of dual antiplatelet therapy (DAPT) reduces the risk of hospitalization for heart failure (HHF).

METHODS: In this nationwide, population-based retrospective cohort study, propensity score matching was used on the Taiwan's National Health Insurance Research Database to select 8,644 pairs of patients with NSTEMI and similar baseline characteristics receiving NG-DES or BMS implantation between January 1, 2007 and December 31, 2016. A competing risk model was constructed to evaluate the risk of HHF in the NG-DES and BMS groups. Death was considered a competing risk.

RESULTS: Rates of cumulative incidence competing risk for HHF at 1, 2, 3, 4, and 5-year follow-ups were lower in the NG-DES group (4.11%, 5.63%, 6.72%, 7.65%, and 8.89%, respectively) than in the BMS group (5.89%, 7.81%, 9.25%, 10.8%, and 11.9%, respectively). After adjustment for all clinical variables, NG-DES implantation was associated with a lower risk of HHF than BMS implantation after 5 years, with an adjusted subdistribution hazard ratio of 0.71 (95% CI = 0.64-0.79, p < 0.001). These results are in agreement with those of patients who received DAPT for >6 months.

CONCLUSIONS: NG-DESs may reduce HHF risk in patients with NSTEMI who receive an undefined duration of DAPT.
