8/30/2023 0 Comments Timi 3 flow.![]() ![]() Failure to achieve TIMI 3 flow continues to be a powerful predictor of mortality after primary PCI in the contemporary era. CONCLUSIONS: In this large-scale, randomised trial, failure to restore normal TIMI flow after primary PCI in STEMI occurred in 12.9% of patients, and was associated with patient-related factors (age), anatomical factors (anterior MI location), and angiographic factors (baseline TIMI 0/1 flow and lesion length). The three-year mortality of patients in whom final TIMI 3 flow was achieved was significantly lower than that of patients in whom TIMI 3 flow was not achieved (5.5% vs. A total of 3,845 treated lesions (3,362 vessels) were analysed by the core lab 2,942 vessels (87.5%) and 2,758 patients (87.1%) had final TIMI 3 flow, while 407 (12.9%) had TIMI flow <3. unfractionated heparin plus a glycoprotein IIb/IIIa inhibitor (n=1,802). METHODS AND RESULTS: The HORIZONS-AMI trial randomised 3,602 patients with STEMI undergoing primary PCI to bivalirudin (n=1,800) vs. TIMI Flow Grade 1.5 - Left Anterior Descending Artery Additional ExamplesĬlick here for other examples of TIMI flow grade 1.Predictors of suboptimal TIMI flow after primary angioplasty for acute myocardial infarction: results from the HORIZONS-AMI trial.ĪIMS: The predictors of TIMI flow <3 after PCI in patients with acute myocardial infarction have not been examined in a contemporary, large-scale multicentre prospective study. TIMI Flow Grade 1 - Left Anterior Descending Artery Had cinefilming continued longer, dye may have reached the landmark. 1.5: dye leaks well past the area of obstruction but fails to opacify the entire coronary bed prior to the end of cinefilming.1.0: dye minimally leaks past the area of obstruction.Contrast material passes beyond the area of obstruction but fails to opacify the entire coronary bed distal to the obstruction for the duration of the cineangiographic filming sequence. TIMI grade 1 flow is defined as penetration without perfusion.
