Abstract :Objective: The mechanisms underlying worse clinical outcomes in previously unrecognized diabetic (DM) patients in ST-elevation myocardial infarction (STEMI) are unclear. It was hypothesized that poor chronic glucose control might be related to greater myocardial damage. Material and Method: 51 newly diagnosed DM patients with glycated hemoglobin A1c (HbA1c) > 6.5 comprised the DM group, 54 sex- and age-matched individuals with normal glucose metabolism served as the non-DM group. Each patient underwent primary angioplasty for STEMI. The levels of cardiac specific markers before angioplasty, during angioplasty, at 6, 12, and 18 h after angioplasty were recorded. SPSS 10 package program was used to analyse data. Results: In both DM and non-DM groups troponin peaked at 6 h. Peak troponin levels were similar in both groups (diabetics, 22.89 ± 18.19 vs. non-diabetics, 32.67 ± 17.68 ng/ml, p=0.168). Conclusions: HbA1c > 6.5 is not related to extent of infarction in previously unrecognized DM patients presenting with STEMI. Future studies assessing the effects of other factors unrelated to chronic glucose control on myocardial damage and cardiovascular event rates in these patients would be of great interest.
