Current Management Strategies for Non-st Segment Elevation Myocardial Infarction
نویسندگان
چکیده
The term “acute coronary syndrome” encompasses unstable angina and non-ST-segment elevation myocardial infarction (UA/ NSTEMI) and ST-segment elevation myocardial infarction (STEMI). UA/NSTEMI is the combination of two closely related clinical entities (i.e., a syndrome), whereas STEMI is a distinct clinical entity. UA/NSTEMI is characterized by an imbalance between myocardial oxygen supply and demand. Most often, the syndrome develops because of decreased myocardial perfusion resulting from coronary narrowing caused by nonocclusive thrombus formation subsequent to disruption of an atherosclerotic plaque. In contrast, STEMI results from an occlusive thrombus.

Background: There is conflicting data about prognostic implication of electrocardiographic (ECG) left ventricular hypertrophy (LVH) in patients with first non- ST-segment elevation myocardial infarction (NSTEMI). We aimed to examine the association of left ventricular hypertrophy (LVH) on admission electrocardiogram with adverse outcomes in patients with NSTEMI. Methods: In the present study, ...

Background & Objective: Patients with ischemic heart disease classified to two major groups: patients with stable angina and patients with Acute Coronary Syndrome (ACS). Previous studies showed that posterior segment of left ventricle is a silent segment on ECG, and routine 12 leads electrocardiogram (ECG) is not sensitive for evaluation of posterior infarction. This study designed for evaluati...

Background :In addition to diagnosing the acute myocardial infarction (MI), stratifying high-risk patients and proper treatment strategies are important issues in managing patients complaining of chest pain and suspecting MI. Many studies have been conducted to predict the occlusion site by interpreting the ST segment deviations in Electrocardiogram (ECG).Additional posterior and right precor...
