Prognostic significance of glycosylated hemoglobin in nondiabetic patients in acute coronary syndrome

Background: The role of glycosylated hemoglobin (HbA1c) in predicting the outcome of acute coronary syndrome (ACS) remains largely controversial. Much lesser is known of its importance in nondiabetics. Herein, we conducted a study to seek the association between the levels of HbA1c and the clinical outcome in nondiabetic patients who presented with ACS. Objective: The objective was to determine the impact of HbA1c levels on the severity and complications of ACS in nondiabetics. Materials and Methods: This observational cross-sectional study included 100 patients without diabetes mellitus who were admitted to the coronary care unit with symptoms suggestive of ACS. The diagnosis of ACS was made on the basis of troponin T value, electrocardiogram (ECG), and echocardiograph. Patients were stratified according to their HbA1c into two groups: Group 1 HbA1c
