The heart being a metabolically active organ constantly needs adequate energy and a good continuous supply of blood to carry out its activities.Heart attack can occur due to a number of factors related with the blood circulation and interruption in oxygen supply to heart muscles.
If an area of the heart musculature receives insufficient supply of blood,the oxygen supply to this area becomes deficient. Due to deficient supply of oxygen of oxygen, the cardiac muscles, which are extremely sensitive, will die and this will result in a heart attack.Heart attack may also be caused by a narrowing or clot in coronary blood vessels.
ANGINA PECTORIS as a mild type of heart attack. It is also caused due to insufficient supply of blood to the cardiac muscles due to the narrowing of the coronary blood vessels.The symptoms of angina pectoris are the same as those of the heart attack i.e. chest pain and shooting pain in the left arm and shoulder.
