GRACE score
Also written as: GRACE — Global Registry of Acute Coronary Events
A risk stratification tool for predicting mortality and ischemic events in acute coronary syndromes.
Full Definition
The GRACE (Global Registry of Acute Coronary Events) score is a validated risk prediction model that estimates in-hospital and 6-month mortality risk for patients with acute coronary syndromes. The score incorporates eight variables: age, heart rate, systolic blood pressure, serum creatinine, Killip class, cardiac arrest at admission, ST-segment deviation, and elevated cardiac biomarkers. GRACE scores are categorized as low (<109), intermediate (109-140), or high (>140) risk, guiding treatment intensity and invasive management timing.
Usage
Usage note: Always capitalize GRACE as it is an acronym. Include 'score' when referring to the calculation.
