History

Background: no reflow has been recognized as a serious primary percutaneous coronary intervention-associated complication, its incidence is related with poor clinical consequences. The goal of the present research is to evaluate the angiographic and clinical determinants of no-reflow. Methods: The clinical and angiographic characteristics of cases of primary percutaneous coronary intervention for acute ST-segment elevation myocardial infarction at the Shaheedul-Mihrab center between January 2015 and September 2016, were retrospectively evaluated. Results: There were 11.5% no-reflow cases. While diabetes, smoking history, sex category, and infarct location did not affect the probability of no-reflow, a history of hypertension and older age did. A higher syntactic score, a greater thrombus burden, and a low primary TIMI flow were all corelated with no re-flow.
