Abstract
BACKGROUND: In patients presenting with acute coronary syndrome (ACS), the number of diseased vessels may affect the efficacy of a complete revascularisation strategy.
AIMS: The authors sought to evaluate the safety and efficacy of immediate complete revascularisation (ICR) and staged complete revascularisation (SCR) in patients presenting with ACS stratified by the number of diseased vessels.
METHODS: In this prespecified analysis of the BIOVASC trial, ICR was compared with SCR in patients with two-vessel disease (2VD) or three-vessel disease (3VD). The primary endpoint was a composite of all-cause mortality, myocardial infarction (MI), any unplanned ischaemia-driven revascularisation or cerebrovascular events at 1 year after the index procedure. Comparisons were performed using Cox regression.
RESULTS: A total of 1,525 patients were enrolled in the BIOVASC trial, of whom 1,177 presented with 2VD and 265 with 3VD. In the 2VD group, 613 patients were assigned to ICR and 564 to SCR. In the 3VD group, 117 patients were assigned to ICR and 148 to SCR. ICR and SCR led to similar results in both the 2VD (hazard ratio [HR] 0.76, 95% confidence...
