Posted: at 7:40 am

The loss of living heart muscle as a result of coronary artery occlusion. MI or its related syndromes (acute coronary syndrome or unstable angina) usually occurs when an atheromatous plaque in a coronary artery ruptures, and the resulting clot obstructs the injured blood vessel. Continue reading

Myocardial infarction diagnosis – Wikipedia

Posted: at 7:40 am

A diagnosis of myocardial infarction is created by integrating the history of the presenting illness and physical examination with electrocardiogram findings and cardiac markers (blood tests for heart muscle cell damage).[1][2] A coronary angiogram allows visualization of narrowings or obstructions on the heart vessels, and therapeutic measures can follow immediately. At autopsy, a pathologist can diagnose a myocardial infarction based on anatomopathological findings Continue reading

ST-Segment Elevation Myocardial Infarction

Posted: at 2:45 am

ST-segment elevation myocardial infarction (STEMI) is the term cardiologists use to describe a classic heart attack. It is one type of myocardial infarction in which a part of the heart muscle (myocardium) has died due to the obstruction of blood supply to the area. The ST segment refers to the flat section of an electrocardiogram (ECG) reading and represents the interval between jagged heartbeats Continue reading

A myocardial infarction (MI), commonly known as a heart attack, occurs when a portion of the heart is deprived of oxygen due to blockage of a coronary artery. Coronary arteries supply the heart muscle (myocardium) with oxygenated blood. Without oxygen, muscle cells served by the blocked artery begin to die (infarct) Continue reading

Myocardial infarction (acute): Early rule out using high …

Posted: at 9:41 pm

NICE has assessed 3 assays which measure cardiac troponin levels in the blood, to help the NHS decide whether to use these products. The assays are called Elecsys Troponin T high sensitive, ARCHITECT STAT High Sensitive Troponin-I and AccuTnI+3. Cardiac troponins are proteins which are released into the blood when heart muscle has been damaged, for example, during a heart attack. Continue reading

What is Ischemic Heart Disease? Ischemic heart disease is caused by an imbalance between the myocardial blood flow and the metabolic demand of the myocardium.Reduction in coronary blood flow is related to progressive atherosclerosis with increasing occlusion of coronary arteries. Blood flow can be further decreased by superimposed events such as vasospasm, thrombosis, or circulatory changes leading to hypoperfusion. Continue reading
