BACKGROUND Whereas survival after lytic therapy for myocardial infarction is strongly dependent on early administration, it is unknown whether the otherwise excellent outcomes in patients undergoing primary PTCA for acute myocardial infarction, in whom TIMI-3 flow rates of >90% may be achieved, can be further improved by early reperfusion. METHODS AND RESULTS Among 2507 patients enrolled in 4...
Since the advent of reperfusion therapy for acute ST elevation myocardial infarction, the “open artery hypothesis” proposed that benefit is achieved from early reperfusion of the occluded coronary artery, which limits the size of infarction, reduces the degree of left ventricular dysfunction, and improves survival.1 After numerous studies confirmed the benefit of a patent infarct-related artery...
BACKGROUND The TIMI Score for ST-segment elevation myocardial infarction (STEMI) was created and validated specifically for this clinical scenario, while the GRACE score is generic to any type of acute coronary syndrome. OBJECTIVE Between TIMI and GRACE scores, identify the one of better prognostic performance in patients with STEMI. METHODS We included 152 individuals consecutively admitte...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
BACKGROUND Chest pain is one of the most common causes of the admission to the emergency departments. It, however, can be due to numerous diseases some of which are life threatening. OBJECTIVES In the current study, we evaluated the prognostic value of TIMI (Thrombolysis in Myocardial Infarction) and Modified TIMI risk scores to stratify the risk for patients with atypical chest pain being di...
BACKGROUND Diagnosis of coronary artery disease in women is more difficult because of lower specificity of symptoms and diagnostic accuracy of noninvasive testing. We sought to examine the relationship between gender and cardiac biomarkers in patients with unstable angina (UA)/non-ST-segment elevation myocardial infarction (NSTEMI). METHODS AND RESULTS In the TACTICS-TIMI 18, OPUS-TIMI 16, an...
INTRODUCTION The thrombolysis in myocardial infarction (TIMI) risk score is calculated as the sum of independent predictors of mortality and ischemic events in ST elevation acute myocardial infarction (STEMI). Several studies show that the neutrophil to lymphocyte ratio (NLR) is a prognostic inflammatory marker. In preliminary studies, platelet to lymphocyte ratio (PLR) has been proposed as a p...
BACKGROUND Many mortality risk scoring tools exist among patients with ST-elevation Myocardial Infarction (STEMI). A risk stratification model that evaluates STEMI prognosis more simply and rapidly is preferred in clinical practice. METHODS AND FINDINGS We developed a simple stratification model for blood examination by using the STEMI data of AMI-Kyoto registry in the derivation set (n = 1,0...
