The GRACE point score sums the implemented points for age, heart rate, systolic blood pressure, serum creatinine, Killip class, cardiac arrest at admission, ST-segment deviation and abnormal cardiac biomarkers.

Continuous in-hospital mortality model

xb = intercept + Σ(coefficient × encoded variable)

Variable	Encoding or unit	Coefficient
Intercept	Constant	−7.7035
Age	Years	0.0531
Heart rate	Beats/min	0.0087
Systolic blood pressure	mm Hg	−0.0168
Serum creatinine	mg/dL after unit conversion	0.1823
Killip class	I = 1, II = 2, III = 3, IV = 4	0.6931
Cardiac arrest at admission	Present = 1, absent = 0	1.4586
ST-segment deviation	Present = 1, absent = 0	0.8755
Abnormal cardiac biomarkers	Present = 1, absent = 0	0.4700

Mortality probability (%) = 100 × exp(xb) / [1 + exp(xb)].

The continuous estimate is distinct from the point-score risk categories.
