Myocardial Infarction (Overview)

Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & the risk of death.

What are the complication of myocardial infarction?

What are the complication of myocardial infarction?

Several possible: There are a range of possible complications. The heart is a muscle, and can be weakened by a heart attack and lead to heart failure. The heart has a conduction system which can be damaged and can lead to arrhythmias and cardiac arrest. Many people die from their heart attack, while others have one and don't realize it. Unfortunately about 1/2 of the time the first sign of heart disease is death. ...Read more

Multiple methods: Myocardial infarction (mi) is suspected by symptoms usually including chest pain. The conclusive diagnosis is established based on a combination of specific abnormalities of the electrocardiogram (ekg) and presence of certain heart enzymes that leak into the blood during an mi. The most common enzymes are called ck-mb and troponin. ...Read more

Does ischemia or thrombosis cause myocardial infarction?

Does ischemia or thrombosis cause myocardial infarction?

Ischemia vs MI: Cholesterol plaque develops in the heart arteries. Progressive narrowing - usually greater than 70% - can lead to lack of blood flow to the heart muscle during exercise or rest and causes angina or ischemia. Myocardial infarction is due to the rupture of a plaque which causes a blood clot to form (thrombosis) in the artery blocking blood flow to that area of the heart muscle which then dies. ...Read more

How quickly does nitroglycerin act when used to treat a myocardial infarction, i.E. When given in tablet form?

Almost immediately: Nitroglycerin given under the tongue is very rapidly absorbed into the blood stream. It can begin to work within 30 - 60 seconds to relieve chest pain and increase blood flow to the heart. Taking Nitroglycerin during a suspected heart attack should not delay calling 911 however. ...Read more

Infarction (Definition)

When the blood supply of a tissue is compromised by whatever mechanism, the tissue will stop working and if blood flow is not restored, the tissue will eventually die ("infarct", both verb and noun). The clinical picture that runs with development of an infarct ("heart attack"; ...Read more
