The correlation of thrombolysis in myocardial infarction frame count with insulin resistance in patients with slow coronary flow.
BACKGROUND
It has been reported that coronary endothelial dysfunction plays an important pathogenetic role in patients with slow coronary flow (SCF). Insulin resistance is defined as impairment of insulin-stimulated glucose and/or lipid metabolism, while endothelial dysfunction is defined as paradoxical or inadequate endothelial-mediated vasodilation. In this study, we aimed to evaluate insulin resistance in patients with SCF.


METHODS
The study population included 25 patients with SCF and 28 healthy controls. Insulin resistance was estimated via homeostasis model assessment insulin resistance index (HOMA-IR).


RESULTS
Patients with SCF had higher high-sensitive C-reactive protein (hs-CRP) and HOMA-IR scores (P<0.05) than controls. Mean thrombolysis in myocardial infarction frame count had significant correlation with hs-CRP, fasting plasma insulin levels and HOMA-IR score (r=0.566, P<0.05; r=0.883, P<0.05; r=0.884, P<0.05, respectively).


CONCLUSIONS
In patients with SCF, thrombolysis in myocardial infarction frame counts and hs-CRP are correlated with increased insulin resistance and thus, it can be suggested that insulin resistance and inflammation may, in part, have a role in the pathogenesis of SCF.
