Comparison of SYNTAX and Gensini Scores in the Decision of Surgery or Percutaneous Revascularization in Patients With Multivessel Coronary Artery Disease.

Introduction:  Many scoring systems have been developed to determine the extent of coronary artery disease (CAD) in patients with multi-vessel disease. The most widely used of these are Synergy between percutaneous coronary intervention with Taxus and cardiac surgery (SYNTAX) and Gensini scoring. Gensini scoring system can successfully show coronary plaque burden. In our study, we aimed to test the predictive power of SYNTAX and Gensini scores for surgical or percutaneous intervention decisions made by the cardiac team in patients with three-vessel disease.

Methods: A total of 476 patients without ST-elevation myocardial infarction with the three-vessel disease were included in the study. SYNTAX and Gensini scores of the patients were calculated from their coronary angiographies. Receiver operating characteristic curve (ROC-curve) analysis was performed using both scores.

Results:  Both the SYNTAX score and Gensini score were able to predict heart team decisions (AUC: 0.759, 0.680; p<0.001). Diabetes and smoking were more common in patients who were decided to have surgery (p<0.001).

Conclusion:  In the light of our study results, the decisions to be made with the SYNTAX score will be closer to the decisions of the heart team than the Gensini score.
