Figure 1
Results of Protocolized Inpatient HbA1c Screening among Patients Presenting with STEMI in North India, by Baseline Glycemic Status.
Abbreviations: DM, diabetes mellitus; HbA1c, glycated hemoglobin; STEMI, ST-segment elevation myocardial infarction.
The left panel represents the glycemic status of NORIN STEMI participants, before and after protocolized inpatient HbA1c screening. The panel to the right shows the distribution of HbA1c levels of NORIN STEMI participants without known dysglycemia at the time of presentation. Established diabetes was defined as a self-reported history of diabetes or clinical history by chart review. Euglycemia was defined as screening HbA1c <5.7%. Prediabetes and diabetes were defined as screening HbA1c 5.7–6.4% and ≥6.5%, respectively.

Clinical Outcomes of Patients Presenting with STEMI in North India, by Glycemic Status.
Abbreviations: HF, heart failure; LV, left ventricle; MI, myocardial infarction.
All models included adjustment for age, sex, body mass index, tobacco use, history of hypertension, heart failure, prior MI, and prior stroke.
