Age-dependent impact of the SYNTAX-score on longer-term mortality after percutaneous coronary intervention in an all-comer population.

BACKGROUND: The Synergy between Percutaneous Coronary Intervention with TAXUS and Cardiac Surgery (SYNTAX)-score is a validated tool for risk stratification and revascularization strategy selection in patients with complex coronary artery disease. The aim of this study was to analyse its age-related prognostic value. METHODS: SYNTAX-score was calculated in 1331 all-comer patients undergoing percutaneous coronary intervention (PCI): 463 patients ≥ 75 years and 868 patients < 75 years. Outcomes of interest were all-cause mortality at one and two years. RESULTS: = 0.138). CONCLUSIONS: Age modifies the impact of the SYNTAX-score on longer-term mortality after PCI. Among patients < 75 years, the SYNTAX-score independently predicts the risk of death at one and two years after PCI, while among patients ≥ 75 years its predictive role is limited to the first year after PCI. Further studies are needed to evaluate the value of SYNTAX-score for selecting the most appropriate revascularization strategy among elderly patients.
