Background: Although insertion of multiple stents into a single coronary vessel during single-vessel percutaneous coronary intervention (PCI) is common, there are no data on long-term occurrence of major adverse cardiac events (MACE) in patients treated with multiple stents versus a single stent. Methods: The incidence of MACE (death, myocardial infarction, or target vessel revascularization) during long-term follow-up was investigated in 634 patients who underwent single-vessel PCI. Of the 634 patients, 319 (50%) had a single stent, and 315 (50%) had multiple stents inserted. Stepwise Cox regression analyses were performed to identify significant independent prognostic factors for MACE. Results: At 47-month follow-up, MACE occurred in 61 of 319 patients (19%) who had a single stent versus in 57 of 315 patients (18%) who had multiple stents (P not significant). Significant independent predictors of MACE were use of vein grafts (hazard ratio = 1.94; 95% CI, 1.24–3.03; P = 0.0038) and use of drug-eluting stents (hazard ratio = 0.49; 95% CI, 0.34–0.72; P = 0.0002). Conclusions: At long-term follow-up of single-vessel PCI, the incidence of MACE was similar in patients with multiple or single stents inserted even after controlling for the length of stents.
