Key result
Higher admission glucose is linked to higher final TIMI frame counts post-PCI in non-diabetic STEMI.
Why the study?
Admission hyperglycemia is associated with poor prognosis in acute myocardial infarction, but its relationship with final TIMI frame counts after successful primary PCI in STEMI patients was unclear.
Are admission glucose levels associated with impaired coronary flow (assessed by TIMI frame count) after successful primary PCI in non-diabetic STEMI patients?
Population
73 non-diabetic acute STEMI patients undergoing successful primary PCI with final TIMI 3 flow
Comparison
Higher versus lower admission glucose values
Design
Prospective observational study

May flag microvascular dysfunction risk in non-diabetic STEMI after PCI; leaves open whether glucose control alters outcomes.
Observational (n=73)
Are admission glucose levels associated with impaired coronary flow (assessed by TIMI frame count) after successful primary PCI in non-diabetic STEMI patients?
Effect estimate: β=0.04 (95% CI 0.02-0.085)
p-value: p=0.04
High admission glucose values are significantly associated with impaired microvascular coronary flow (higher TIMI frame counts) despite angiographically successful primary PCI in non-diabetic STEMI patients.
Ege et al. (2011) conducted an observational in acute ST-elevation myocardial infarction (STEMI) (n=73). Admission glucose values was evaluated on Final TIMI frame count of the culprit artery (β=0.04, 95% CI 0.02-0.085, p=0.04). Higher admission glucose values were significantly associated with higher final TIMI frame counts of the culprit artery after successful primary PCI in non-diabetic STEMI patients (β=0.04, p=0.04).
