Granger 2003 in-hospital GRACE 1.0: integer nomogram points from age, heart rate, systolic BP, creatinine (mg/dL or µmol/L), Killip class 1-4, cardiac arrest, ST-segment deviation, and elevated initial enzymes. Total 1-372. In-hospital mortality percent is that paper's printed score readout. Not GRACE 2.0, not Fox 2006 6-month, not ESC 108/140 cutoffs. Not a medical device and not a cath-lab order.
