After a patient has survived an acute myocardial infarction, the long-term survival can be predicted from clinical parameters.

history of a previous myocardial infarction |

history of hypertension |
-0.998 |
0 |
highest pulse rate >=100 beats/minute (tachycardia) |

score =
= SUM (points for each parameter)
Interpretation
LN ((probability of survival) / (1 - (probability of survival)) =
= LN ((probability of survival)/ (probability of death)) =
= 1.842 - (score)
probability of surviving 5 years after a myocardial infarction =
= EXP(1.842 - (score)) / (1 + (EXP(1.842 - (score))))
