OBJECTIVES To verify whether incomplete revascularisation (IR), quantified using the rSYNTAX (Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery) score and ΔSYNTAX% 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 and ΔSYNTAX% scores. Increasing ΔSYNTAX% 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.
