    Abstract:
    OBJECTIVE: Admission hyperglycemia is associated with poor prognosis in patients with acute myocardial infarction. Final Thrombolysis in Myocardial Infarction (TIMI) frame counts of culprit coronary arteries may show significant variability despite successful coronary reperfusion after primary percutaneous coronary intervention (PCI). In this prospective observational study, relationship between final TIMI frame counts of the culprit coronary artery and admission glucose values was investigated in patients who underwent successful primary PCI due to acute ST-elevation myocardial infarction (STEMI). METHODS: During a 6- month period of time, 73 non-diabetic patients presented with acute STEMI who have undergone primary PCI with final TIMI 3 flow were consecutively included in the study. Patients were divided into two groups according to final TIMI frame counts. Group 1 (n=53) consisted of patients with final TIMI frame counts of the culprit coronary artery within the two standard deviation of predefined values and Group 2 (n=20) consisted of those with higher TIMI frame counts. Statistical analysis was performed using Chi-square, Mann-Whitney U tests and multiple linear regression analysis. RESULTS: Despite similar fasting glucose values, admission glucose levels were significantly higher in Group 2 as compared to Group 1 (138 [114-165] vs. 123 [97-143] mg/dl, p=0.03). In whole group, admission glucose values were significantly correlated with corrected TIMI frame counts of culprit coronary arteries (r=0.30, p=0.01). In addition, there were significant association between admission glucose values and peak creatine kinase-MB (r=0.36, p=0.007) values as well as left ventricular ejection fraction (r=-0.43, p=0.009). In multiple linear regression analysis, only admission glucose value was found to be significantly related to the final TIMI frame count of the culprit artery (β=0.04, 95%CI: 0.02-0.085, p=0.04). CONCLUSION: High admission glucose values were significantly associated with impaired coronary flow even after successful primary PCI in non-diabetic patients with STEMI.
