Hyperglycemia in the Hospital Can Lead to Diabetes in the Future

Myocardial infarction (MI) patients who are hospitalized and are hyperglycemic may have increased risk for diabetes…. 

This study analyzed data from a national cohort of patients with acute myocardial infarction (AMI) without known diabetes. 127 Veteran’s Affairs hospitals were analyzed between 2005 and 2011. 10,499 patients without known diabetes were evaluated, 98% of whom were men. Among the patients evaluated in this study, 1,761 (16.8%) had hyperglycemia at admission. The primary outcome was evidence of diabetes either at hospital discharge or in the subsequent six months. Outcomes were measured by diagnostic codes of diabetes, prescriptions and/or elevated hemoglobin A1c. Regression modeling was used to evaluate the association between hyperglycemia at admission and evidence of diabetes.

Of the patients evaluated, 651 patients had evidence of diabetes after six months following the initial hospitalization. 208 patients, who initially presented with hyperglycemia, were diagnosed with having diabetes six months after initial hospitalization. 169 patients were diagnosed with diabetes at or before hospital discharge. Among those diagnosed at or before discharge, 71 had hyperglycemia at admission.
