Resumen:
Objective: To compare second generation drug eluting stents (2 DES) with first generation (1DES) for
the treatment of patients (pts) with multiple coron ary 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 cont rolled study in pts with MVD including
left main and treated with 2DES (Firebird 2, Microp ort). 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 remarka ble low incidence of MACCE in
unadjusted and adjusted analysis
