GRACE Risk Score Calculator

The GRACE score was developed from the Global Registry of Acute Coronary Events to estimate adverse outcomes in people presenting with an acute coronary syndrome. It combines information available near admission rather than relying on one laboratory value or electrocardiographic feature. The model is used in professional guidance to support early risk stratification, communication, monitoring, and decisions about invasive management alongside clinical judgment. This calculator implements the established integer point system for eight variables: age, heart rate, systolic blood pressure, serum creatinine, Killip class, cardiac arrest at admission, ST-segment deviation, and elevated cardiac biomarkers. Age, faster pulse, lower blood pressure, and higher creatinine contribute progressively more points. Pulmonary congestion or shock represented by higher Killip class, arrest, ST deviation, and elevated enzymes add fixed points. The final integer score is grouped here using common in-hospital mortality thresholds: 108 or less is low risk, 109 through 140 is intermediate risk, and above 140 is high risk. Killip class summarizes heart-failure severity at presentation. Class I means no clinical signs of heart failure. Class II includes findings such as rales, an S3 gallop, or elevated jugular venous pressure. Class III represents pulmonary edema, and class IV represents cardiogenic shock. Correct classification matters because it has a large effect on the score. Likewise, creatinine must be entered in milligrams per deciliter; convert results reported in micromoles per liter before using this version. GRACE has several validated endpoints and implementations, including in-hospital death and death after discharge. A point total must be paired with the correct endpoint, population, and validated conversion model. The broad mortality bands displayed here intentionally avoid presenting false precision and should not be substituted for an institution’s validated GRACE 2.0 system. Repeat values after treatment may not represent the same baseline prediction. An acute coronary syndrome is an emergency. This calculator is intended for trained healthcare use and education, not self-triage or delayed care. Chest pressure, breathlessness, sweating, fainting, or symptoms suggesting myocardial infarction require emergency evaluation. Treatment decisions must incorporate the ECG, serial troponin, comorbidities, bleeding risk, frailty, coronary anatomy, patient preferences, and local cardiology protocols.
