Prognostic values of SYNTAX score II in patients with coronary artery disease undergoing percutaneous coronary intervention – Cohort study

Abstract

Background: The data on prognostic values of SYNTAX score II in patients undergoing percutaneous coronary intervention is limited. We report predictive utility of SYNTAX score II in relation to in hospital and 1 year mortality of the patients undergoing percutaneous coronary intervention. Methods: This was a cohort study of patients who underwent percutaneous coronary intervention (PCI) at a single centre from January 2018 to December 2019. In hospital and 12-month events and mortality was analysed among 1000 patients. The patients were divided into 3 groups based on tertiles of Syntax II score (27.7). Result: The total mortality at 12 months was 60 (6%). Major adverse cardiac events (MACE) occurred in 87 (9%). The patients who died had higher SYNTAX score II score compared to those alive at 12 months 34 (38, 24) vs 24 (28.1, 20.9) P 27.7) compared the lower tertiles. Conclusion: The patients who had higher SYNTAX score II had more in hospital and 12 month mortality and major adverse cardiac events (MACE). SYNTAX II score is a better predictor of in-hospital, and 12 month cardiovascular and all cause mortality.
