GRACE score
Risk stratification tool for predicting mortality and ischemic outcomes in acute coronary syndrome patients.
Full Definition
The GRACE (Global Registry of Acute Coronary Events) score is a validated risk assessment tool used to predict in-hospital and long-term mortality in patients presenting with acute coronary syndromes. The score incorporates clinical variables including age, heart rate, systolic blood pressure, creatinine level, Killip class, cardiac arrest at presentation, elevated cardiac biomarkers, and ST-segment deviation. GRACE scores are categorized as low (<140), intermediate (140-177), or high risk (>177) for 6-month mortality, guiding treatment intensity and discharge planning decisions.
Usage
Usage note: Specify 6-month or in-hospital GRACE score when precision needed; 'GRACE' is typically capitalized.
