Background
Risk stratification is fundamental to the management of patients presenting with acute coronary syndromes (ACS). The Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score was originally developed to quantify the anatomical complexity of coronary artery disease and guide revascularization decisions. Over time, the SYNTAX score has evolved into a powerful prognostic tool capable of predicting procedural success, adverse cardiovascular outcomes, and long-term mortality in patients undergoing acute coronary interventions.
Objective
To evaluate the predictive value of the SYNTAX score in acute coronary interventions and examine its association with procedural complexity, major adverse cardiovascular events (MACE), mortality, and long-term clinical outcomes.
Methods
A comprehensive review of clinical trials, observational studies, registries, and guideline recommendations was conducted. The relationship between SYNTAX score categories and outcomes following acute coronary interventions was analyzed.
Results
Higher SYNTAX scores are consistently associated with increased lesion complexity, procedural complications, incomplete revascularization, recurrent ischemic events, heart failure, and mortality. The SYNTAX II score and contemporary risk models further enhance predictive accuracy by incorporating clinical variables.
Conclusion
The SYNTAX score remains a valuable tool for risk assessment and treatment planning in acute coronary interventions. Integration of anatomical and clinical risk factors provides improved prognostic utility and supports individualized patient management.
