Input: Question: Does admission glucose improve GRACE score at 6 months and 5 years after myocardial infarction?
Answer: APG is a predictor of 6-month and 5-year mortality, each mmol/l increase in APG being associated with a mortality increase of 17 and 12%, respectively, independent of the GRACE risk score. However, adding APG to the GRACE model did not result in significantly improved clinical risk stratification.
Output:
no
