Hi. Heart attack in medical terms is myocardial infarction (mi). Which means a permanent damage to heart muscles. Heart muscles need oxygen rich blood to function. This is done by the blood vessels which supply the heart called coronary arteries. When these blood vessels get blocked it results in loss of blood supply to heart muscles. Resulting in heart attack. During an attack. Persons feels giddy, sweats, chest pain is severe which can be felt in that left shoulder, back, jaws etc, vomitting and fluctuating blood pressure (high or low). It can present differently too. But the above are common symptoms. Thank you.
