It is common knowledge that the symptoms of heart attack can be identified before the attack (myocardial infarction) take place. This attack is usually sudden and occurs without prior warning. This is one of the major reasons for deaths relating to this medical situation.
Only a few persons are enlightened about the few less obvious signs of an impending heart attack and these signs manifest days before the real attack.
One main reason for heart attacks is the accumulation of plaque in the coronary artery. This disrupts the normal blood supply in the system and moments later the attack will take place.
A tissue dies during a heart attack. This is due to improper circulation of blood and the patient will experience excruciating pains and strong pressure in the heart. If the individual is alone and there is no presence of medical personnel, the dead tissue may lead to death.
