Definition, Causes, Symptoms And Treatment Of Heart Attack

Heart attack is most commonly caused by a sudden obstruction of the blood supply to part of the heart muscle. It is a sudden illness or obstruction in the coronary artery (coronary thrombosis) that disturbs the breathing. The main risk is that the heart will stop beating.

The effect of a heart attack depends largely on how much of the heart muscle is affected; many casualties recover completely. Heart attack is also caused by Cardio Vascular disease called ATHEROSCLEROSIS (This is the build up of plague caused by cholesterol and other debris that narrows the arteries (clot)). Drug such as aspirin is used to dissolve the blood clot and limit the extent of damage to the heart muscle.

Causes of Heart Attack
  • Blood clot in the coronary artery located in the heart
  • High blood pressure

  • The size of the heart and the size of the body.

Signs and Symptoms of Heart Attack
