Predictive Factors of No Reflow during Primary Angioplasty

Introduction: No reflow during primary angioplasty is associated with a poor prognosis despite the reopening of the culprit coronary. The aim of our work was to determine the predictive factors of no reflow. Methodology: Single-center retrospective analytical study from June 2000 to December 2016 that included patients presenting with STEMI took care of by primary angioplasty. No reflow was defined according to angiographic criteria: a TIMI flow Results: The prevalence of no reflow was 24%. In univariate analysis mean age, diabetes,hypertension, tachycardia, hypotension, killip stage 4 left ventricular failure, hyperglycemia > 11, renal failure, left ventricular dysfunction, tritruncal status, common trunk involvement, initial TIMI flow at 0, significant thrombotic load, delay to angioplasty > 6 hours, and predilation were all correlated with no reflow with a p 75 years [OR = 6.02, 95% CI 1.4 - 27, p = 0.014], tachycardia [OR = 4.3, 95% CI 1.6 - 7.4, p = 0.037], delay to angioplasty > 6 hours [OR = 1.3, 95% CI 1.1 - 2.1, p = 0.003] and high thrombotic load [OR = 1.5, 95% CI 1.3 - 3.2, p = 0.02] were independent predictors of no reflow. Conclusion: No reflow is associated with a poor short-term prognosis. Its care requires knowledge of predictive factors, prevention and treatment.
