Symptoms of a heart attack

A heart attack can cause chest pain, shortness of breath, anxiety, light-headedness, and pain in one or both of your arms, neck, jaw and back.More than a million Americans have heart attacks each year. Heart attacks are also called myocardial infarctions (MI). "Myo" means muscle, "cardial" refers to the heart, and "infarction" means death of tissue because of a lack of blood supply. This tissue death can cause lasting damage to your heart muscle..

When the plaque is hard, the outer shell cracks. This is called a rupture. Platelets (disc-shaped things in your blood that help it clot) come to the area, and blood clots form around the plaque. If a blood clot blocks your artery, your heart muscle becomes starved for oxygen. The muscle cells soon die, causing permanent damage. Limit alcohol: If you don't drink already, don't start. If you do drink, limit how much you drink. The recommendation is no more than one drink a day if you are a woman and no more than two a day if you are a man. Drinking raises your heart rate and blood pressure. It also increases the level of fat in your blood and can cause weight gain.

A myocardial infarction (commonly called a heart attack) is an extremely dangerous condition caused by a lack of blood flow to your heart muscle. The lack of blood flow can occur because of many different factors but is usually related to a blockage in one or more of your heart’s arteries. Without blood flow, the affected heart muscle will begin to die. If blood flow isn’t restored quickly, a heart attack can cause permanent heart damage and death. When a heart attack happens, blood flow to a part of your heart stops or is far below normal, which causes that part of your heart muscle to die. When a part of your heart can’t pump because it’s dying from lack of blood flow, it can disrupt the pumping sequence for the entire heart. That reduces or even stops blood flow to the rest of your body, which can be deadly if it isn’t corrected quickly. (Source: my.clevelandclinic.org)
