Objective To compare second generation drug eluting stents (2DES) with first generation (1DES) for the treatment of patients (pts) with multiple coronary vessel disease (MVD). Background Although 2DES improved safety and efficacy compared to 1DES, MVD remains a challenge for percutaneous coronary interventions. Methods ERACI IV was a prospective, observational, and controlled study in pts with MVD including left main and treated with 2DES (Firebird 2, Microport). We included 225 pts in 15 sites from Argentina. Primary endpoint was the incidence of major adverse cardiovascular events (MACCE) defined as death, myocardial infarction (MI), cerebrovascular accident (CVA) and unplanned revascularization; and to compare with 225 pts from ERACI III study (1DES). PCI strategy was planned to treat lesions ≥70% in vessels ≥ 2.00 mm, introducing a modified Syntax score (SS) where severe lesions in vessels < 2.0 mm and intermediate lesions were not scored. Results Baseline characteristics showed that compared to ERACI III, ERACI IV pts had higher number of diabetics ( P = 0.02), previous revascularization ( P = 0.007), unstable angina IIb/IIIc ( P < 0.001) and three vessels/left main disease ( P = 0.003). Modified SS was 22.2 ± 11. At 2 years of follow‐up ERACI IV group had significantly lower incidence of death+ MI + CVA, ( P = 0.01) and MACCE ( P = 0.001). MACCE rate was similar in diabetics, (5.8%) and nondiabetics (7.0%). After performing a matched propensity score, MACCE remain significantly lower in ERACI IV ( P = 0.005). Conclusion This registry showed that 2DES in MVD has a remarkable low incidence of MACCE in unadjusted and adjusted analysis. © 2016 Wiley Periodicals, Inc.
