The present study aimed to identify possible clinical predictors for no-refl ow in patients with AMI after primary percutaneous coronary intervention(PCI).METHODS: A total of 312 consecutive patients with AMI who had been treated from January 2008 to December 2010 at the Cardiology Department of East Hospital, Tongji University School of Medicine were enrolled in this study. Inclusion criteria were:(i) patients underwent successfully primary PCI within 12 hours after the appearance of symptoms; or(ii) patients with ischemic chest pain for more than 12 hours after a successful primary PCI within 24 hours after appearance of symptoms. Exculsion criteria were:(i) coronary artery spasm;(ii) diameter stenosis of the culprit lesion was ≤50% and coronary blood f low was normal;(iii) patients with severe left main coronary or multivessel disease, who had to require emergency revascularization. According to thrombolysis in myocardial infarction(TIMI), the patients were divided into a reflow group and a no-reflow group. The clinical data, angiography f indings and surgical data were compared between the two groups. Univariate and multivariate logistic regressions were used to determine the predictors for no-ref low.RESULTS: Fifty-four(17.3%) of the patients developed NR phenomenon after primary PCI. Univariate analysis showed that age, time from onset to reperfusion, systolic blood pressure(SBP) on admission, Killip class of myocardial infarction, intra-aortic balloon pump(IABP) use before primary PCI, TIMI flow grade before primary PCI, type of occlusion, thrombus burden on baseline angiography, target lesion length, reference luminal diameter and method of reperfusion were correlated with no-reflow(P<0.05 for all). Multiple logistic regression analysis identified that age >65 years [OR=1.470, 95% confi dence interval(CI) 1.460–1.490, P=0.007], long time from onset to reperfusion >6 hours(OR=1.270, 95%CI 1.160–1.400, P=0.001), low SBP on admission <100 mmHg(OR=1.910, 95%CI 1.018–3.896, P=0.004), IABP use before PCI(OR= 1.949, 95%CI 1.168–3.253, P=0.011), low(≤1) TIMI fl ow grade before primary PCI(OR=1.100, 95%CI 1.080–1.250, P<0.001), high thrombus burden(OR=1.600, 95%CI 1.470–2.760, P=0.030), and long target lesion(OR=1.948, 95%CI 1.908–1.990, P=0.019) on angiography were independent predictors of no-refl ow.CONCLUSION: The occurrence of no-refl ow after primary PCI for acute myocardial infarction can predict clinical, angiographic and procedural features.展开更多
