Cardiac Risk – Santa Cruz Dataset
Description
This dataset was provided by the Santa Cruz hospital (Lisbon, Portugal) and contains data from 460 consecutive patients admitted with NSTE-ACS between March 1999 and July 2001. The event rate of the combined endpoint (death/myocardial infarction) was 7.2% (33 events).
The characteristics of the dataset are provided in the Table below.
