A nationwide causal mediation analysis of survival following ST-elevation myocardial infarction. Pre-PCI angiographic TIMI flow in the culprit coronary artery influences infarct size and microvascular obstruction in STEMI patients. Schaaf M.J., Mewton N., Rioufol G., Angoulvant D., Cayla G., Delarche N. Normal Flow (TIMI-3) Before Mechanical Reperfusion Therapy Is an Independent Determinant of Survival in Acute Myocardial Infarction. Even among those patients classified as having normal flow (TIMI grade 3 flow, CTFC40), CTFC identified a subgroup of patients with TIMI grade 3 flow who. Stone G.W., Cox D., Garcia E., Brodie B.R., Morice M.-C., Griffin J. Preprocedural TIMI flow and mortality in patients with acute myocardial infarction treated by primary angioplasty. Six- and twelve-month follow-up of the phase I thrombolysis in myocardial infarction (TIMI) trial. TIMI thrombolysis in myocardial infarction PCI percutaneous coronary intervention MVOneg. Nevertheless, over time, in-hospital complications have decreased among patients with TIMI 0, while 30d MACE and 1-year mortality has remained unchanged.ĭalen J.E., Gore J.M., Braunwald E., Borer J., Goldberg R.J., Passamani E.R. Download scientific diagram TIMI flow grade before and after percutaneous coronary intervention. TIMI flow grade 0 is still more common among patients with STEMI and is associated with poorer prognosis. There was no temporal change of these outcomes in either TIMI flow grade group. Compared with TIMI flow 1-3, patients with TIMI flow 0 had worse 30d MACE and 1-year mortality. In-hospital complications of patients with TIMI flow 0 has significantly decreased over time (36.1% vs 26.8%, P < 0.001) but not amongst patients with TIMI flow 1-3. The majority of patients had pre-procedural TIMI flow 0 (58.9% in the early period and 58.7% in the late period, P = 0.97). Clinical outcomes included in-hospital complications, 30d MACE (death, myocardial infarction, stroke, unstable angina, stent thrombosis, urgent revascularization) and 1-year mortality.Results and Conclusions: Included were 2453 patients. Survey years were divided to early (2008-2010) and late period (2013-2018). A time-dependent analysis stratifying patient by TIMI flow grade 0 and TIMI flow grade 1-3 was performed. We aimed to assess the temporal trends in clinical outcomes according to the TIMI flow grade amongst these patients.ĭata of patients with STEMI from the acute coronary syndrome Israeli Survey (ACSIS) registry. There have been great advances in pharmacologic and invasive treatment of STEMI patients in the current era. Pre-procedural TIMI coronary flow grade in patients with ST segment elevation myocardial infarction (STEMI) is associated with adverse clinical outcomes.
