The ECABG score is a clinical risk assessment tool designed to predict the likelihood of a patient requiring emergency coronary artery bypass graft (CABG) surgery following a planned percutaneous coronary intervention (PCI). It’s used by cardiologists to quickly identify individuals who are at a higher risk of complications and may need to be prepared for an unplanned, urgent surgical procedure. The score is calculated based on several easily accessible clinical and procedural variables, helping to stratify patients into low, intermediate, and high-risk categories. This predictive information can be vital for pre-procedure planning and optimizing patient safety.
