More than a million Americans have heart attacks each year. A heart attack, or myocardial infarction (MI), heart muscle damage is permanent. "Myo" means muscle, "cardial" is from the heart, and "infarction'' means lack of blood supply to tissue death.
What happens during a heart attack?
To nourish the heart muscle of oxygen-rich blood supply requires constant. Coronary arteries supply blood to the heart, providing critical. If you have coronary artery disease, those arteries become narrow and blood can not flow as well as he. Fatty matter, calcium, protein, and inflammatory cells within arterial plaques of various sizes to construction. The plaque deposits are hard on the outside and the inside soft and mushy.
When plaque is hard, outer shell cracks (plaque rupture), platelets (disc-shaped particles in the blood that aid clotting) come in, and blood clots form around the plaque. If a blood clot completely blocks the artery, heart muscle for oxygen "deficit" is. Within a short time, a heart muscle cell death occurs, permanent damage. This is a heart attack.
Although it is unusual, heart attack, a spasm of an artery can be caused by. During a coronary spasm, coronary artery spasm or limited and closed, the heart muscle (ischemia) in the blood supply is reduced. It is at rest, and even in people without significant coronary artery disease can be.
Each coronary artery supplies blood to the heart attacks pictures is a muscle. The amount of damage to heart muscle blocked artery and time between injury and treatment provided by a region depends on the size.
Healing of the heart muscle begins soon after a heart attack and almost eight weeks. Just like a skin wound, the heart's wound heals and a scar will form in the damaged area. However, the new scar tissue does not contract. So, heart-pumping ability is lessened after a heart attack. The amount of lost pumping ability depends on size and location of signs.Article resource by :yeast infection no more scam
Heart attack symptoms
Symptoms of a heart attack include:
Pain, chest pressure, heaviness, pain or arm, or below the breastbone
Back, jaw, neck or arm discomfort radiating from
The fullness, indigestion or choking feeling (the feeling of heartburn may be like)
Sweating, nausea, vomiting, dizziness or
Extreme weakness, anxiety, or shortness of breath
Rapid or irregular heartbeat
By rest or nitroglycerin under the tongue, a heart attack, symptoms last 30 minutes or more during and are not relieved.
Some people either (a "silent" myocardial infarction) is a heart attack without symptoms. A silent MI can occur in anyone, but it is more common in people with diabetes.
