Every year, millions of people in the area of the world experienced a heart attack. Not all heart attacks result in death. However, generally every patient who had suffered a heart attack suffered some impact follows. While the rest did not help.The heart is a muscle that pumps blood throughout the body. In a heart attack (myocardial infarction), part of the muscle to die while not getting blood. To stay healthy, the heart requires oxygen and other nutrients carried by blood. This is obtained through the artery (blood vessel) disease, which wrap the outside of the heart.
These diseases can affect any part of the heart. However, the most common disease is a chronic disease in which coronary artery is called atherosclerosis. Therefore, heart disease commonly known and most common is coronary heart disease or coronary artery disease. This disease most often causes a heart attack in someone who can cause death. The cause is narrowing of the coronary arteries, where the vessel serves to provide blood to the heart muscle. Constriction caused by a pile of cholesterol or other proteins derived from food that enters the body. This buildup causes the coronary arteries become stiff. Stiffness is called atherosclerosis.
Atherosclerosis occurs if there is plaque buildup or deposition of fat on artery walls. After a time, plaque can accumulate, harden and narrow the arteries, and inhibit blood flow to the heart. Coronary artery disease or Coronary Artery Disease (CAD) is that basically leads to most heart attacks.
Blockage in one or more coronary arteries can cause a heart attack suddenly. The reason for asking the heart exceeds the available oxygen so that trigger heart attacks. Why? If the muscle does not receive oxygen for a long time, can damage surrounding tissue. Unlike other networks, the heart muscle does not regenerate. The longer the attack, the more damage to the heart and the more likely dead.
Even in the arteries that are not too narrow because of plaque and fatty timbungan, accumulation of plaque can rupture and form a crust of blood or thrombus. In addition, the diseased arteries also tend to experience sudden muscle contractions. Thus, a piece of crust in the blood can form a contraction, releasing chemicals which then result in narrowing the artery wall, triggering a heart attack.
If the work system of the heart is damaged, the normal rhythm of the heart can become chaotic and the heart began to tremble with erratic or experiencing fibrillation. This abnormal rhythm known as arrhythmia is a deviation from a normal heart rhythm. This will cause the heart loses its ability to effectively pump blood to the brain. Within ten minutes, the patient is brain dead and did not help.
In addition to coronary heart disease due to fat deposition in the arterial wall, there are also other heart diseases caused by abnormalities at birth. Example of an imperfect heart, heart valve disorders, weakened heart muscle. Other causes are bacteria that cause infections of the heart.
Symptoms of Heart Disease :
The symptoms are perceived if you have coronary heart disease include pain or pain in the chest where most people thought it was just as indigestion. Then other symptoms of feeling depressed in the middle of the chest for 30 seconds to 5 minutes. Another was a cold sweat, pounding, dizziness, and felt like fainting. These symptoms are not always felt by the sufferer. Another warning sign is gasping for breath when exercising.
For several months before the heart attack patients with cardiovascular disease usually often feel very tired. Do not consider these symptoms caused by lack of sleep and stress from work.
Suppressed pain or numbness in the chest, called angina, giving a warning to half of those who suffer a heart attack. Some people get breathless or exhausted and feeling limp as the symptoms, indicating that the heart is not getting enough oxygen because of coronary blockage.
Usually a few days before having a massive heart attack, a person will experience muscle contractions suddenly in the chest which is a small attack or a mild heart attack. Generally mild heart attack occurred before the big attack several days later.
