Association of initial thrombolysis in myocardial infarction flow grade with mortality among patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention: a National Registry of Myocardial Infarction-5 (NRMI-5) analysis



Association of initial thrombolysis in myocardial infarction flow grade with mortality among patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention: a National Registry of Myocardial Infarction-5 (NRMI-5) analysis



American Heart Journal 162(1): 178-183



Epicardial coronary flow, as assessed by the Thrombolysis in Myocardial Infarction flow grade (TFG), prior to primary percutaneous coronary intervention (pPCI) for ST-segment elevation myocardial infarction (STEMI) has been associated with short- and long-term mortality in randomized clinical trials. This study was designed to determine the relationship between initial TFG and mortality in a large, heterogeneous, real-world population of STEMI patients undergoing pPCI. The relationship between pre-pPCI TFG among patients undergoing pPCI and in-hospital mortality was evaluated among STEMI patients from 24 to 26 in the National Registry of Myocardial Infarction. Of 8,337 STEMI patients, 6,595 (79.1%) had pre-pPCI TFG /1.
