Clinical outcomes of state-of-the-art percutaneous coronary revascularisation in patients with three-vessel disease: two-year follow-up of the SYNTAX II study.

Abstract

AIMS:

The purpose of the study was to investigate whether the favourable outcomes of state-of-the-art PCI in the SYNTAX II trial, demonstrated at one year, were maintained at two-year follow-up.

METHODS AND RESULTS:

The SYNTAX II study was a multicentre, single-arm study that investigated the impact of a contemporary PCI strategy on clinical outcomes in 454 patients with de novo three-vessel coronary artery disease, without left main disease. Clinical outcomes in SYNTAX II were compared to the predefined PCI (SYNTAX-I PCI) and coronary artery bypass graft (SYNTAX-I CABG) cohorts from the landmark SYNTAX trial (SYNTAX-I), selected on the basis of equipoise for long-term (four-year) mortality utilising the SYNTAX score II. At two years, major adverse cardiac and cerebrovascular events (MACCE: a composite of all-cause death, any stroke, myocardial infarction, or revascularisation) in SYNTAX II were significantly lower compared to SYNTAX-I PCI (13.2% vs. 21.9%, p=0.001). Furthermore, similar two-year outcomes for MACCE were evident between SYNTAX II PCI and SYNTAX-I CABG (13.2% vs. 15.1%, p=0.42).

CONCLUSIONS:

At two years, clinical outcomes with the SYNTAX II strategy remained superior to the predefined SYNTAX-I PCI cohort, and similar to the predefined SYNTAX-I CABG cohort.
