Comment on: Predicting operative mortality in patients undergoing coronary artery bypass surgery.

摘要

Lawrence and colleagues have highlighted the inadequacies and pitfalls of risk scores in predicting operative mortality in patients undergoing coronary artery bypass surgery. The dominance of coronary artery system, the degree of luminal obstruction, the number of diseased coronary vessels and calcification of coronaries and the aorta should be taken into consideration in the risk stratification of patients undergoing coronary artery bypass grafting (CABG). The above points are addressed in the SYNTAX scoring system (developed in May 2009), which is a unique scoring system to assess the severity and the anatomical complexity of coronary artery disease and provides a guide to revascularisation options to the cardiologists. Incorporating the SYNTAX score into the Euroscore will provide an additive value in predicting outcome after CABG.
