These diseases can affect any part of the heart. However, the most common disease is a chronic disease in the coronary arteries is called atherosclerosis. Therefore, heart disease commonly known and most common is coronary heart disease or coronary artery disease. The disease is most common cause of 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. Narrowing caused by a stack of cholesterol or other proteins from the food that enters the body.This buildup causes the coronary arteries become stiff. Stiffness is called atherosclerosis.
Atherosclerosis occurs when there is accumulation of plaque or fatty deposits on artery walls. Over time, plaque can build up, harden and narrow arteries and block 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 heart attack suddenly. The reason for the heart for oxygen exceeds that available to trigger a heart attack. Why? If the heart muscle does not receive oxygen for a long time, the surrounding tissue can be damaged. Unlike other tissues, the heart muscle does not regenerate. The longer the attack, the more damage to the heart and the more likely to die.
Even in the arteries that are not too narrow because of plaque and fatty timbungan, the accumulation of plaque can break off and form a crust of blood or thrombus. In addition, the diseased arteries are also likely to experience sudden muscle contractions.Thus, a piece of crust in the blood can form a contraction, releasing chemicals that later resulted in narrowing the artery wall, triggering a heart attack.
If the working system of the heart is damaged, the heart’s normal rhythm can become chaotic and the heart began to tremble with uncertainty or fibrillate. This abnormal rhythm known as arrhythmia is a deviation from normal heart rhythm. This will cause the heart loses its ability to pump blood effectively to the brain. Within ten minutes, brain death and the patient was beyond 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. For example, an imperfect heart, abnormal heart valves, heart muscle weakness. Another cause is the bacteria that cause infections of the heart.
