Myocardial Infarction (heart attack):

It is more commonly known as a heart attack and is a medical condition that occurs when the blood supply to a part of the heart is interrupted and leads to the death of some cells of the heart muscles.


Causes of Myocardial Infarction (heart attack):

A heart attack may be caused by a blood clot in coronary arteries. It is a medical emergency and the leading cause of death for both men and women all over the world. The term myocardial infarction is derived from myocardium (the heart muscle) and infarction (tissue death).


Symptoms of Myocardial Infarction (heart attack):

Severe chest pain is the most common symptom of myocardial infarction and is often described as a sensation of tightness, pressure, or squeezing. Pain radiates most often to the left arm, but may also radiate to the lower jaw, neck, right arm, and back Loss of consciousness and even sudden death can occur in myocardial infarction.


Treatments of Myocardial Infarction (heart attack):

Immediate treatment for suspected acute myocardial infarction includes oxygen supply, aspirin, and a sublingual tablet of glyceryl trinitrate. Most cases of myocardial infarction are treated with angioplasty (mechanical widening of a narrowed or obstructed blood vessel) or bypass surgery (surgery in which arteries or veins from elsewhere in the patient's body are grafted to the coronary arteries to improve the blood supply to heart muscles).


Prevention of Myocardial Infarction (heart attack):

There is therefore increased emphasis on preventing cardiovascular disorders by modifying risk factors, such as healthy eating, exercise, and avoidance of smoking.
