    The reflow phenomenon is a complication of percutaneous coronary intervention (PCI), characterized by a weakened blood flow despite the restoration of patency in the epicardial coronary artery. We sought to evaluate the incidence, predictors and impact of the reflow phenomenon in patients with acute myocardial infarction (STEMI) treated with the drug-invasive strategy (EFI). For this, we analyzed 1012 patients with IAMCSST, who received fibrinolytic therapy in the initial care and were systematically transferred to the tertiary hospital for cardiac catheterization and PCI, when indicated. This study stands out for originality, since there is scarce knowledge about the phenomenon of no reflow in the specific EFI scenario. The results showed that the incidence of the phenomenon was 9.2%. After applying a multivariate logistic regression model, the independent predictors related to the phenomenon were: TIMI coronary flow pre-PCI ? 2 (OR 3.38 CI 95% 2.80-5.92), higher values ??in the TIMI (OR 2.09 95% CI 1.69-3.12) and GRACE (OR 1.02 95% CI 1.01-1.04), advanced age (OR 1.05 95% CI 1.02-1.08 ) And greater amplitude of supra ST pre fibrinolysis (OR 1.02 95% CI 1.002-1.043). The reflow phenomenon was also related to higher mortality rates (22.6% versus 4% p <0.001) and in-hospital complications. It is concluded that the phenomenon of no reflow in patients with IAMCSST treated according to EFI has an incidence of 9.2%. Its predictors were prenormal PCI, advanced age, higher pre-fibrinolysis ST, and higher values ??of TIMI and GRACE scores. The phenomenon represented a negative impact due to higher mortality rates and in-hospital complications.
