Death of the heart muscle often causes chest pain and electrical instability of the heart muscle tissue. A heart undergoing ventricular fibrillation simply quivers, and cannot pump or deliver oxygenated blood to the brain. Permanent brain damage and death can occur unless oxygenated blood flow is restored within five minutes. A heart attack is when part of the muscle dies off, due to lack of a blood source. This loss of blood occurs when there is blockage by clots.
Clots are little ball-looking groups that store blood.
They are very harmful when in they are in the heart or and major organ. An artery carries nutrients as well as blood into the heart. When muscle in the heart dies, it causes pain often called a heart attack. A heart that is suffering from a heart attack usually does not beat correctly, causing blood containing the needed oxygen to not get throughout the body. This lack of oxygen can do permanent damage to the brain if the person that is stricken by the heart attack refuses treatment immediately.
