Conclusions This study revealed that not all patients with acute STEMI had totally occluded culprit coronary artery but some of them had angiographic TIMI I-III flow in the infarct-related artery. The length of the lesion was significantly smaller in patients who had TIMI III flow compared to those who had TIMI 0-II flow. In 11% of cases, left anterior descending (LAD) artery had TIMI III flow as compared to other vessels (p<0.001). Among those who had TIMI III flow, 11.2% were those with door to balloon time of <90 minutes.

Fourteen percent of patients with TIMI III flow were of age group 51 to 60 years. Stent deferral was proved to be better than immediate stenting after recanalization of IRA, in achieving TIMI III flow, reducing risk of 6 months MACE, and restoration of myocardial function in a subset of STEMI patients presenting with large thrombus burden. TIMI III flow was present in 11.4% of patients before primary PCI, while TIMI 0, I and II flow were present in 57.1%, 15.1%, and 16.3% of patients respectively (p<0.001). 1 This semiquantitative coronary angiographic tool places a patient's coronary flow into one of four different categories and has been shown to be associated with mortality. Hypertension was the leading risk factor in 54.1% (4340) of patients. For many years, epicardial coronary flow has been simply assessed by the TIMI (thrombolysis in myocardial infarction) flow grade. Results A total of 8018 patients were included in this study who presented with STEMI and underwent primary PCI. Data were entered and analyzed on Statistical Package for the Social Sciences (SPSS) version 19 (IBM Corp., Armonk, NY, USA). These data were collected after taking consent from those patients who presented to hospital within 12 hours of symptoms and underwent primary PCI. Methodology This study is an audit of already saved data in the catheterization laboratory of the National Institute of Cardiovascular Diseases (NICVD), Karachi, that was collected prospectively from January 2016 to December 2018. The aim of this study was to evaluate the frequency of pre-procedural TIMI III flow in those patients who underwent primary PCI for acute STEMI in a public sector hospital in Karachi, Pakistan. This study was conducted to find out the frequency of TIMI flow in acute STEMI patients in view of the above concept. However during primary percutaneous coronary intervention (PCI) thrombolysis in myocardial infarction (TIMI) 0 flow is not observed in all patients' culprit arteries in angiographic views. The incidence of multivessel coronary artery disease (MVD) was lower in the E-ROSC group than in the L-ROSC group (16.7% versus 58.8%, P = 0.001).Collateral and TIMI flow were not associated with ease of resuscitation, but MVD may have a negative impact on resuscitation, especially in VF patients.Ĭollapse to resuscitation time Coronary angiography Resuscitation.Background ST elevation myocardial infarction (STEMI) is classically characterized by total occlusion of the culprit coronary artery. We included ACS patients who had CPA with ventricular fibrillation (VF) as an initial rhythm, were successfully resuscitated, underwent coronary angiography (CAG), had a culprit lesion, and were diagnosed with ACS (n = 58 age, 63.7 ± 12.0 years 93.1% male).We divided the 58 patients into two groups, an early ROSC group (ROSC ≤ 20 minutes: E-ROSC) and a late ROSC group (ROSC > 20 minutes: L-ROSC), and then analyzed their characteristics.The finding of a collateral artery for the culprit lesion location, Rentrop II-III, and TIMI III flow on CAG on arrival presented no significant differences between the two groups (Rentrop II-III: 25.0% versus 23.5%, P = 0.90 TIMI III: 33.3% versus 35.3%, P = 0.88). Hence, we investigated this relationship in ACS patients with OHCA.A cohort of 2779 patients was admitted to our emergency center due to cardiopulmonary arrest (CPA) between April 2011 and March 2015. The relationship between the findings from the study of coronary images and return of spontaneous circulation (ROSC) interval is still unknown. Acute coronary syndrome (ACS) is the major cause of out-of-hospital cardiac arrest (OHCA).
