Electrocardiography in suspected myocardial infarction has the main purpose of detecting ischemia or acute coronary injury in emergency department populations coming for symptoms of myocardial infarction (MI). Also, it can distinguish clinically different types of myocardial infarction. Continue reading →

Clinical Relevance of Anterior Myocardial Infarction Anterior STEMI results from occlusion of the left anterior descending artery (LAD). Anterior myocardial infarction carries the worst prognosis of all infarct locations, mostly due to larger infarct size. Continue reading →

Identifying an acute myocardial infarction on the 12-lead ECG is the most important thing you can learn in ECG interpretation. Continue reading →

Half the deaths from a heart attack occur in the first 3 or 4 hours after symptoms begin. It is crucial that symptoms of a heart attack be treated as a medical emergency. Continue reading →

A syndrome of prolonged, severe chest pain was first described in medical literature in 1912 by James Bryan Herrick, who attributed the syndrome to coronary thrombosis, the development of a clot in a major blood vessel serving the heart.

Later evidence indicated, however, that, though thrombotic occlusion of an atheromatous lesion in a coronary artery is the most common cause of the disorder, the manifestations are the result of the death of an area of heart muscle (infarction).
