Effect of Abnormal Fasting Plasma Glucose Level on All-Cause Mortality in Older Patients With Acute Myocardial Infarction: Results From the Beijing Elderly Acute Myocardial Infarction Study (BEAMIS)

An increased FPG level was associated with a relatively higher risk of in-hospital mortality in men but not in women. Nonetheless, increased and decreased FPG levels at admission could predict higher mortality rates regardless of sex. There was a striking U-shaped relationship between FPG levels and in-hospital and 3-year mortality. The effect of abnormal FPG level on outcomes among older patients with AMI did not vary significantly by sex.
