TIMI Risk Score as A Predictor for No-Reflow Phenomenon in Patients Undergoing Primary Angioplasty for Acute STEMI
نویسنده
چکیده
Background: Angiographic no-reflow phenomenon after primary Percutaneous Coronary Intervention (PCI) in patients with acute ST-elevation myocardial infarction (STEMI) may result in unfavorable outcome. Objectives: The aim of the study was to evaluate the TIMI risk score of STEMI as a predictor of no-reflow phenomenon after primary PCI. Patients and Methods: We analyzed 627 patients presenting with acute STEMI and underwent primary PCI within 24 hours of symptoms onset, we divided the patients into high risk patients (TIMI risk score >!5) and low risk patients (TIMI risk score 0-4). Results: The rate of no-reflow phenomenon was significantly higher in the high risk group compared to the low risk group (22% vs. 6.9% p :0.001), the c-statistics predictive value of the TIMI score for no reflow was 0.78 ( p .001). After application of multivariate regression analysis, TIMI risk score of STEMI was an independent predictors of no-reflow phenomenon odds ratio 1.71 (CI 95% 1.31-2.1). Conclusion: TIMI risk score of STEMI on admission can predict angiographic no-reflow phenomenon after primary PCI.

Introduction: No-reflow phenomenon in coronary vessels, manifested in some patients with reperfused acute myocardial infarction (MI), is associated with poor clinical and functional outcomes. Therefore, evaluation of predisposing risk factors can be helpful in risk assessment and identification of patients at higher risk. Herein, we aimed to study the predictive factors for the development of...

Background No-reflow is an important factor as it predicts a poor outcome in patients undergoing primary angioplasty. In comparison with patients attaining TIMI 3 flow, patients with no-reflow have an increased incidence of ventricular arrhythmias, early congestive cardiac failure, cardiac rupture and cardiac death. As such, it is of paramount importance to consider strategies to prevent the oc...

Introduction: No-reflow increases the complications and mortality rate of primary percutaneous coronary intervention (PCI). Therefore, it is important to identify patients at a higher risk of developing no-reflow. This study aimed to systematically review the prognostic value of the platelet-to-lymphocyte ratio (PLR) to predict no-reflow. Materials and Methods:</s...
