Knowledge of the probable outcome after myocardial infarction (MI) is important in formulating an appropriate plan of management, as with ST elevation MI versus non-ST elevation MI (non-Q-wave MI). The following information on risk stratification is relevant to decision making. Acute MI in-hospital mortality is about 12–14% (Table 2.1.). Several characteristics alter the in-hospital and postdis...

Acute ST segment elevation is regarded generally as the sine qua non of evolving Q wave myocardial infarction (MI) because such electrocardiographic (ECG) injury is believed to be a marker of transmural ischemia and a forerunner of transmural necrosis. Alternatively, ST segment depression with or without T wave inversion is viewed as the dominant ECG feature of non-Q wave MI. However, this hypo...

background: studies on the prognosis of st elevation myocardial infarction (stemi) versus non-st elevation myocardial infarction (non-stemi) have shown different results. the present study was designed to compare the early outcome and left ventricular systolic function of patients with st and non-st elevation myocardial infarction. methods: the patients' information was derived from 10,065 cons...

  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...

OBJECTIVES This study investigated early electrocardiographic findings in relation to left ventricular (LV) function, extent and size of infarction, and microvascular injury in patients with acute myocardial infarction (MI) treated with percutaneous coronary intervention (PCI). BACKGROUND The electrocardiogram (ECG) is the most used and simplest clinical method to evaluate the risk for patien...

BACKGROUND Several large, randomized clinical trials have shown that early thrombolytic therapy substantially reduces early mortality after acute myocardial infarction (MI). In most trials, eligibility criteria include typical chest pain and diagnostic ST segment elevation in two or more contiguous leads of the standard 12-lead ECG. Unfortunately, large areas of the thoracic surface are left un...

Background: The role of temperature changes, as an environmental risk factor, in the human health status has been investigated in recent studies. Accordingly, the present two-year study was conducted to evaluate the incidence of myocardial infarction (MI) in warm and cold seasons in Ali-ibn Abi Talib Hospital, Rafsanjan, Iran. Materials and Methods: In this descriptive and cross-sectional st...
