OBJECTIVES To verify whether incomplete revascularisation(IR),quantified using the rSYNTAX(Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery)score andΔSYNTAX%score,could predict short-(in-hospital mortality)and long-term outcomes(12-month mortality)in octogenarians undergoing percutaneous coronary intervention(PCI).METHODS&RESULTS A retrospective analysis of 665 consecutive octogenarian patients presenting for PCI to a UK centre was performed.The baseline SYNTAX and rSYNTAX scores were assessed from angiographic images.ΔSYNTAX%score was calculated(ΔSYNTAX%=((SYNTAX-rSYNTAX)/SYNTAX)×100%))to measure the relative completeness of revascularisation.Kaplan-Meier analysis assessed survival at 12 months by tertiles of rSYNTAX andΔSYNTAX%scores.IncreasingΔSYNTAX%score was associated with reduced in-hospital mortality(P=0.017),and improved survival benefit(log rank 14.8,P=0.001)at 12 months.CONCLUSIONS Enhancing the completeness of revascularisation in octogenarians selected to undergo PCI is associated with a lower in-hospital mortality and a survival benefit at 12 months.
