Heart attack can occur when the blood supply cannot reach the heart due to narrowed heart arteries, commonly known as ischemic heart disease. If blood flow isn’t restored quickly, the section of heart muscle begins to die.

After  muscle die a person experiences chest pain and electrical instability of the heart muscle tissue. If the blockage isn’t treated quickly, the portion of heart muscle fed by the artery begins to die. Healthy heart tissue is replaced with scar tissue. This heart damage may not be obvious, or it may cause severe or long-lasting problems.

The risk of a heart attack increases when a man is over 45 and a woman is over 55. One of 5 heart attacks is silent—the damage is done, but the person is not aware of it.

About one-fifth of all heart attacks are silent, that is, the victim does not know one has occurred. Although the victim feels no pain, silent heart attacks still can damage the heart.

The outcome of a heart attack also depends on where the blockage is, whether the heart rhythm is disturbed, and whether another coronary artery supplies blood to that part of the heart. Blockages in the left coronary artery usually are more serious than in the right coronary artery. Blockages that cause an arrhythmia, an irregular heartbeat, can cause sudden death.

Plaque is covered in a solid fibrous cap on the outside but its inside is soft due to its fatty contents.7 If the plaque in your coronary artery is ruptured, the fatty substances become exposed. Platelets rush to the plaque, forming a blood clot after that Your heart becomes starved of oxygen-rich blood, and your nervous system immediately sends signal to your brain about what’s going on. You will start sweating and your heart rate will speed up. You will also feel nauseous and weak.

Heart failure is a condition in which the heart can’t pump enough blood to meet the body’s needs. Arrhythmias are irregular heartbeats. Ventricular fibrillation is a life-threatening arrhythmia that can cause death if not treated right away.
