HEART ATTACK AND SYMPTOMS

Coronary Heart Disease:

• A heart attack happens when blood flow to oxygen-rich parts of the heart muscle suddenly becomes blocked. Most heart attacks occur due to coronary heart disease (CHD).

• CHD is a condition in which the waxy substance called plaque builds inside the coronary arteries. These arteries supply oxygen-rich blood to the heart.

• When the plates builds up in arteries, this condition is called miażdżyca.W buildup of plaque occurs over many years.

• In the end, the plate surface can rupture (break) inside the artery. This causes a blood clot to form on the surface of the plate. If the clot becomes large enough, it can mostly or completely block blood flow through the coronary artery.

• If the blockage is not treated quickly, part of the 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 serious or long-term problems.

• Heart attack or myocardial infarction (MI), is permanent damage to heart muscle. "Myo" means muscle, "heart" refers to the heart and "infarction" means death of tissue due to lack of blood supply.

• Heart muscle requires a constant supply of oxygen-rich blood to the heart to provide coronary odżywiać.Tętnic with this critical blood supply. If you have coronary artery disease, those arteries become narrow and blood can not flow as they should. Fatty substances, calcium, protein and inflammatory cells build up in arteries to form tiles of different rozmiarach.Depozytów board are hard on the outside and soft and mushy on the inside. 

Coronary Artery Contraction:

• Less often cause a heart attack is a serious contraction (tightening) wieńcowej.Skurcz artery cuts off blood flow through the artery. Cramps may occur in the coronary arteries that are not affected by atherosclerosis.

What causes coronary artery spasm is not always the jasne.Skurcze may be associated with:

•       The use of certain drugs such as cocaine

•       Stress or pain

•       Exposure to extreme cold

•       cigarette smoking

When the table is hard, outer shell cracks (plaque rupture), platelets (disc-shaped particles in the blood that aid clotting) come from the area, and blood clots form around the table. If the clot completely blocks the artery, the heart muscle becomes "hungry" for oxygen. In a short time, the death of heart muscle cells, causing permanent damage. It is a heart attack.

• Although it is unusual, a heart attack can also be caused by coronary artery spasm. During coronary spasm, coronary arteries restrict or spasm on and off, reducing blood flow to the heart muscle (ischemia). It may occur at rest, and may even occur in patients without significant coronary artery disease.

• Each coronary artery supplies blood to the muscle area. sercowego.Stopień myocardial damage depends on the size of the area supplied by the blocked artery, and the time between injury and treatment.

Healing the heart muscle begins soon after a heart attack and takes about eight weeks. Just as skin wounds, the heart heals wounds and scars will form in the damaged area. But the new scar tissue does not contract. Yes, the heart pumping ability is lessened after a heart attack. The amount of lost pumping ability depends on the size and location of the scar.

HEART ATTACK SYMPTOMS:

1.  Discomfort pressure,heaviness,pain in the chest,shoulders or below sternum.
2.  Discomfort radiating to the back jaw, thorat, arm.
3.  Feeling of fulleness,indestion,chocking(may feel hear burn)
4  Dizziness
5  Extreme weakness
6.  Anxiety
7.  Sweating, nausea, vomiting
8.  Fast(or)irregular heart beat
9. Tension

• Some people have heart attack without symptoms silent mycoridal infarction may occur in any one and this quite common among patients with diabetes
