Abstract:
Objective To investigate the association of serum angiopoietin-1 (Ang-1) and angiopoietin-2 (Ang-2) with myocardial reperfusion in ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PCI). Methods A total of 103 consecutive STEMI patients who received primary PCI were enrolled in this study. The patients were divided into two groups according to ST-segment resolution (STR) at 2 h after PCI:STR ≥ 50%group (n=69) and STR<50%group (n=34). Serum concentrations of Ang-1, Ang-2 and Ang-2 to Ang-1 ratios (Ang-2/Ang-1) before and immediately after PCI, 2 h, 6 h, 24 h after PCI were compared. Predictors of poor STR were identiifed by multivariable logistic regression analysis. Results The patients with STR≥50%had significant higher serum Ang-1 levels (P < 0.05) and lower Ang-2/Ang-1 ratios (P < 0.01) from before PCI to 6 h after PCI than those with STR < 50%;Ang-1 and Ang-2/Ang-1 at 24 h after PCI, and Ang-2 at all time points were not signiifcantly different between the two groups (P>0.05). In multivariable logistic regression analysis, Ang-2/Ang-1 before PCI was independently associated with STR < 50%;Other independent predictors were pain to balloon time, infarct related artery (LAD), and TIMI flow grade<Ⅲafter PCI. Conclusions Higher Ang-2/Ang-1 is an independent predictor of poor myocardial reperfusion in STEMI patients after PCI.
