Association of stress hyperglycemia and atrial fibrillation in myocardial infarction.

Background: Stress hyperglycemia has an untoward effect on prognosis in acute myocardial infarction (AMI). Evidence on the interrelationship between stress hyperglycemia and atrial fibrillation (AF) in AMI is sparse. We hypothesized that stress hyperglycemia and AF, both being markers of worse in-hospital prognosis, may be interrelated and we therefore analyzed the relationship between stress hyperglycemia and AF in AMI.
