BACKGROUND A residual stenosis and/or microvascular damage have been proposed as mechanisms of TIMI 2 flow for acute myocardial infarction. Coronary flow dynamics were assessed in patients with TIMI 2 flow to predict whether additional intervention would improve TIMI grade. METHODS AND RESULTS In 35 patients who had a successfully recanalized anterior acute myocardial infarction using angiopl...

OBJECTIVE To determine the correlation of thrombolysis in myocardial infarction (TIMI) risk score with extent of coronary artery disease (CAD) in patients with acute coronary syndrome (ACS). METHODS We conducted a descriptive study among 200 consecutive patients admitted with ACS at Tabba Heart Institute, Karachi from June to December 2008. The TIMI risk score was stratified on seven standard...

Pre-percutaneous coronary intervention (PCI) Thrombolysis In Myocardial Infarction (TIMI) grade 3 flow has been identified as a predictor of final TIMI grade 3 flow and better survival. Yet pharmacologic strategies increasing the rates of pre-PCI TIMI grade 3 flow resulted in more bleeding, without a benefit in survival. The aim of this study was to identify the predictors and implications of s...

BACKGROUND In patients admitted to the emergency department with complaints of chest pain and unstable angina pectoris, ST-elevation MI scoring is done according to risk factors used to calculate risks of urgent revascularization, MI, and death within 14 days. For this calculation, the most widely used scoring system is TIMI risk score. MATERIAL AND METHODS In this prospective, cross-sectiona...

INTRODUCTION Several studies have attempted to demonstrate that the Thrombolysis in Myocardial Infarction (TIMI) risk score has the ability to risk stratify emergency department (ED) patients with potential acute coronary syndromes (ACS). Most of the studies we reviewed relied on trained research investigators to determine TIMI risk scores rather than ED providers functioning in their normal wo...

STUDY OBJECTIVE The Thrombolysis in Myocardial Infarction (TIMI) risk score is a 7-item tool derived from trials of patients with unstable angina/non-ST segment elevation myocardial infarction for risk stratification with respect to outcomes. It has been retrospectively evaluated in emergency department (ED) patients with potential acute coronary syndrome but has not been prospectively validate...

Huge amount of Arabic information and documents are widely spread on the Internet. The accuracy of searching for Arabic documents, as well as other documents, depends on the terms used by the user in the input query to retrieve relevant results and to reduce irrelevant ones. Most results returned are relevant to the query terms not to its meaning. For example, searching for “ ت ص ل ب ا ل ش ر ا ...

BACKGROUND The impact of final Thrombolysis in Myocardial Infarction (TIMI) flow in the infarct-related artery (IRA) on outcomes in non-ST-segment elevation myocardial infarc-tion (NSTEMI) patients treated with percutaneous coronary intervention (PCI) is unknown. This study aimed to evaluate the impact of post-procedural TIMI flow in IRA on outcomes in NSTEMI patients undergoing percutaneous co...

Background: Chest pain is the most common reason for patients to be referred to the emergency department of hospitals. This study was performed to compare the GRACE and TIMI scores in predicting important cardiovascular events in patients. Methods: This descriptive-analytical study was performed on 862 cardiac patients who were referred to the emergency department of Taleghani Hospital in Urmi...
