Prognostic value of the acute-to-chronic glycemic ratio at admission in acute myocardial infarction: A prospective study

Abstract

© 2018 by the American Diabetes Association. OBJECTIVE Acute hyperglycemia is a powerful predictor of poor prognosis in acute myocardial infarction (AMI), particularly in patients without diabetes. This emphasizes the importance of an acute glycemic rise rather than glycemia level at admission alone.We investigated in AMI whether the combined evaluation of acute and chronic glycemic levels, as compared with admission glycemia alone, may have a better prognostic value. RESEARCH DESIGN AND METHODS We prospectively measured admission glycemia and estimated average chronic glucose levels (mg/dL) by the following formula: [(28.7×glycosylated hemoglobin %)-46.7], and calculated the acute-to-chronic (A/C) glycemic ratio in 1,553 consecutive AMI patients (mean±SD age 67±13 years). The primary end pointwas the combination of in-hospital mortality, acute pulmonary edema, and cardiogenic shock. RESULTS The primary end point rate increased in parallel with A/C glycemic ratio tertiles (5%, 8%, and 20%, respectively; P for trend
