Myocardial infarction (MI), commonly called as heart attack, causes death of, or damage to, part of the heart muscle due to severe reduction or stoppage of blood supply to the heart muscle. If a blood clot totally blocks the artery, the heart muscle becomes ‘hungry’ for oxygen. Within a short time, heart muscle cells die, causing permanent damage. Do you know that heart attack and heart blockage are not the same?
Although heart attacks are common above 45 years of age in males and 55 years of age in females, the symptoms of heart attack in females are slightly different than in males. Heart attacks can be fatal, if medical care isn’t received quickly. Also, first-aid for a heart attack can be a live-saver for a person suffering from a chest pain, a key symptom of heart attack.
A person experiences numerous changes in the body during a heart attack.

Additionally, lifestyle changes, exercise and diet plays a key role in the prevention of a second attack.
