What causes anterior myocardial infarction?

An anterior myocardial infarction results from occlusion of the left anterior descending coronary artery. This can cause an ST elevation myocardial infarction or a non-ST segment elevation myocardial infarction.

How is an anterior myocardial infarction treated?

Cardiac catheterization and immediate coronary artery bypass grafting in the first hours of anterior myocardial infarction can be done safely and may reduce in-hospital and long-term mortality.

What is the prognosis for myocardial infarction?

Acute myocardial infarction (MI) is associated with a 30% mortality rate; about 50% of the deaths occur prior to arrival at the hospital. An additional 5-10% of survivors die within the first year after their myocardial infarction.

What are the effects of myocardial infarction?

Myocardial infarction, commonly known as a heart attack, is a serious condition where a coronary artery (a blood vessel of the heart) is blocked and can not supply the heart muscle with blood and oxygen. This causes damage to the heart muscle. The typical symptoms are chest and arm pain, shortness of breath, nausea and a cold sweat.

What are the types of myocardial infarction?

Myocardial infarction has been classified into types 1 to 5 of which type 4 has subtypes a and b. Type 1 is spontaneous myocardial infarction due to a primary coronary event like plaque rupture. Type 2 is secondary to a supply demand mismatch as in coronary vasospasm, anemia or hypotension .

What leads show anterior mi?

Causes of anterior MI as well as in any part of the heart include: Atherosclerosis leading to plaque formation in the coronary arteries – most common cause. Coronary artery vasospasm (constriction) Embolism or blood clots. Carbon monoxide poisoning. Left ventricular hypertrophy (enlargement) Drugs containing cocaine, amphetamines, and ephedrine.
