Aims: The SYNTAX study compared PCI with TAXUS Express stents to CABG for the treatment of de novo 3-vessel and/or left main coronary disease. This study aimed to determine patient characteristics and five-year outcomes after a staged PCI strategy compared to single-session PCI. Methods and results: In the SYNTAX trial, staged procedures were discouraged but were allowed within 72 hours or, if renal insufficiency or contrast-induced nephropathy occurred, within 14 days (mean 9.8±18.1 days post initial procedure). A total of 125 (14%) patients underwent staged PCI. These patients had greater disease severity and/or required a more complex procedure. MACCE was significantly increased in staged patients (48.1% vs. 35.5%, p=0.004), as was the composite of death/stroke/MI (32.2% vs. 19%, p=0.0007). Individually, cardiac death and stroke occurred more frequently in the staged PCI group (p=0.03). Repeat revascularisation was significantly higher in staged patients (32.8% vs 24.8%, p=0.035), as was stent thrombosis (10.9% vs. 4.7%, p=0.005). Conclusions: There is a higher incidence of MACCE in patients undergoing staged compared to single-session PCI for 3-vessel and/or left main disease over the first five years of follow-up. However, these patients had more comorbidities and more diffuse disease.
