The GRACE risk score
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Rim Halaby, M.D. [2]
Overview
The Global Registry of Acute Coronary Events (GRACE) risk score has been developed for the assessment of the risk of death among patients with acute coronary syndrome. There is a GRACE risk score for the estimation of in-hospital mortality and another for mortality in the period from the time of hospital discharge up to 6 months.[1][2]
Grace Risk Score for In-Hospital Mortality
Calculation of Grace Risk Score for In-Hospital Mortality
The total GRACE risk score is calculated by adding the points assigned to the different variable shown below. The highest total possible score 363.[1]

Interpretation of Grace Risk Score for In-Hospital Mortality
A nomogram for the probability in-hospital mortality has been developed based on the GRACE score. Shown below is the probability of in-hospital mortality by the corresponding GRACE score value.[1]
Score | Probability of in-hospital mortality (%) |
≤60 | ≤0.2% |
70 | 0.3% |
80 | 0.4% |
90 | 0.6% |
100 | 0.8% |
110 | 1.1% |
120 | 1.6% |
130 | 2.1% |
140 | 2.9% |
150 | 3.9% |
160 | 5.4% |
170 | 7.3% |
180 | 9.8% |
190 | 13% |
200 | 18% |
210 | 23% |
220 | 29% |
230 | 36% |
240 | 44% |
≥250 | ≥52% |
