A heart attack is an obstruction to the blood supply to the heart's own tissues. In the brain this is a stroke and in the lungs it is a pulmonary embolism. Depending on the severity of the blockage, and how long before treated, the tissues without blood supply will die.
The systemic cells will be in immediate peril should the heart stop working or start working improperly. The cells need a constant supply of oxygen to function and stay living. Blood carries this oxygen to the cells, but it cannot move without the heart pumping. In other words, no pumping of the heart, no movement of the blood, no oxygen delivery to the cells, cells start dying.
Some cells, like muscle cells, will be able to withstand a temporary lack of oxygen due to the alternate pathway of respiration, lactic acid fermentation, it can utilize. However, the cells that need the most oxygen are those in the brain; without a supply of oxygen for even a short period of time, temporary or even permanent neurological damage can result.

They are both blockages in the arteries that supply oxygen and nutrients to the tissues, that ultimately cause irreversible damage to either the heart or brain.
Yes the human heart has nerve tissues that help the brain send messages to th the heart
I believe that its spelled Epinephrine and its just adrenaline thst is used in relation to a heart attack because Epinephrine binds to beta-adrenergic receptors on the heart muscle cells therefore that causes the contraction rate of the heart to increase and it then gets more blood-flow to the tissues in the body hope this helps!!! :)
Yes, it does. It makes you have pain in your joints, feet , or/and back while walking.
heart attack is the dead of cardiac tissues due to insufficent supply of blood.
well, a heart attack can affect you in sport because of your face.
Heart attacks (myocardial infractions) cause tissues and the cells in part pf the heart to die. They actually block blood flow and that loss of blood will cause the cells and tissues to die. Some of these MIs are not large and scar tissue will form. But some are very large and the heart muscle will actually break apart causing death.
When coronary circulation is prevented in humans the result is a heart attack. The function of the coronary circulation is to nourish tissues of the heart.
olol
your heart can stop all together

A heart attack can kill people. Sometimes people are not allowed to do certain things invade they have another heart attack. Sent from my iPad.

How the hell should i know
Normally a number of heart cells die, if enough die then the organism dies.
the heart acts like a motor for circlation
