SYNTAX score
Pronunciation: SIN-taks
Also written as: SYNTAX — Synergy between PCI with Taxus and Cardiac Surgery
Angiographic scoring system used to quantify complexity of coronary artery disease for treatment planning.
Full Definition
The SYNTAX score is a comprehensive angiographic tool that evaluates the complexity and extent of coronary artery disease by assigning points based on lesion characteristics, location, and morphology. Scores are categorized as low (0-22), intermediate (23-32), or high (≥33) complexity. This scoring system helps guide decision-making between percutaneous coronary intervention and coronary artery bypass surgery, particularly in patients with left main or three-vessel disease.
Usage
Usage note: Always capitalize SYNTAX as it is an acronym; scores should be reported with numerical ranges.
