How Heart Disease Could Happen?
Disease can affect any part of the heart. However, most common disease is a chronic disease in which coronary artery is called atherosclerosis. 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. Cause is narrowing coronary artery, where the vessel serves to provide blood to the heart muscle. Constriction caused by a pile cholesterol or other protein derive from food that enter body. This buildup causes the coronary artery 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).
Blockage in one or more coronary artery, can cause a heart attack suddenly. The reason for asking the heart exceeds available oxygen, triggering a heart attack.
If the heart 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 accumulation and fat, 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 working 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 normal heart rhythm. This will cause the heart loses its ability to effectively pump blood to brain. Within ten minutes, brain death and cause of death ..
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 heart.(e-lifestyle.us).
