Analysis of the related risk factor of no-reflow in patients with acute inferior myocardial infarction during PCI

ObjectiveTo investigate the risk factors of no-reflow in patients with acute inferior myocardial infarction during percutaneous coronary intervention(PCI).

MethodsThe data of 126 acute inferior myocardial infarction patients treated with PCI were investigated, and the related risk factors of no-reflow were analyzed.

ResultsOne hundred and twenty-six patients with acute inferior myocardial infarction were successfully treated with PCI, no-reflow in 16 cases were found, and the incidence rate of which was 12.70%.Logistic regression analysis showed that the diabetes(OR=1.047, 95%CI:1.019 to 1.233, P=0.036), reperfusion time(OR=5.281, 95%CI:2.782 to 10.018, P=0.002), TIMI flow grading before PCI(OR=1.735, 95%CI:1.040 to 3.062, P=0.020) and low systolic blood pressure before PCI(OR=1.844, 95%CI:1.153 to 3.638, P=0.015) were the risk factors of no-reflow.

ConclusionsThe incidence of no-reflow in acute inferior myocardial infarction patients is high.The effectively preventive measures against the related risk factor of no-reflow should be implemented, which can reduce the no-reflow risk of PCI.
