Abstract:
Objective To identify independent predictors of no-reflow after primary percutaneous coronary intervention (PPCI)in aged patients with ST-elevation acute myocardial infarction (STEMI), and thus construct a no-reflow predicting model.MethodsTotal of 668 aged patients with STEMI and successfully treated with PPCI were divided into the no-reflow group and the normal flow group. All clinical, angiographic and procedural data were collected. Multiple logistic regression analysis was used to identify independent no-reflow predictors.ResultsThe no-reflow was found in 181 of 668 (27.1%) patients.Multiple stepwise logistic regression analysis identified that admission systolic blood pressure (SBP)<100 mm Hg, collateral circulation 0-1 grade, pre-PCI thrombus score ≥ 4, and intra-aortic balloon pump (IABP) use before PCI were independent noreflow predictors.The no-reflow incidence significantly enhanced as the numbers of independent predictors increased [10.0% (2/20), 13.7% (32/233), 30.8% (85/276), 38.1% (37/97), and 59.5% (25/42) in patients with 0, 1, 2, 3, and 4 independent predictors, respectively,x2 =25.796,P<0.01) ]. ConclusionsThe no-reflow predictors are admission SBP < 100 mm Hg, collateral circulation 0-1grade, pre-PCI thrombus score≥4, and IABP use before PCI in patients with STEMI and treated with PPCI. The prediction model may provide basis for therapeutic decision.
