“” and tips about healthy heart problems. The heart is a vital organ in the human body. Heart always beats for humans is still alive and will stop after the man died. When the heart can no longer function normally will result in very severe disease and the activity can not be run as usual. Definition of general heart is an organ that serves as a muscle that pumps blood throughout the body. In a heart attack (myocardial infarction), part of the heart muscle dies when deprived of blood. To stay healthy, the heart needs oxygen and nutrients carried by the blood. This is obtained through the artery (blood vessel) coronary, which wrap around the outside of the heart.
The disease can affect any part of the heart. However, the disease is the most common chronic disease of 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 the most frequent cause of heart attack in someone who can cause death. The cause is narrowing of the coronary arteries, which vessel serves to provide blood to the heart muscle. Narrowing caused by piles of cholesterol or other proteins derived from foods that enter the body. This buildup causes the coronary arteries become stiff. Rigidity is called atherosclerosis. Atherosclerosis occurs when there is accumulation of plaque or fatty deposits in artery walls. Over time, plaque can accumulate, harden and narrow the arteries and impede ” flow to the heart. Coronary artery disease or coronary artery disease (CAD) that sets the stage for most heart attacks.
A blockage in one or more coronary arteries can cause a heart attack suddenly. The reason for the heart for oxygen exceeds the available triggering a heart attack. Why? If the heart muscle does not receive oxygen for a long time, the surrounding tissue may be damaged. Unlike other tissues, the heart muscle does not regenerate. Even in the arteries that are not too narrow because of plaque deposits and fat, accumulation of plaque can rupture and form a blood crust or thrombus. In addition, diseased arteries are also likely to experience sudden muscle contractions. Thus, a piece of a blood crust can be formed in a contraction, release chemicals that then lead to the narrowed artery walls, triggering a heart attack. If the working system of the heart is damaged, the heartвЂ™s normal rhythm can become chaotic and the heart begins to tremble with uncertainty or experiencing fibrillation. This abnormal rhythm known as arrhythmia is a deviation from normal heart rhythm. This will cause the heartвЂ™s ability to pump blood effectively to the brain. Within ten minutes, brain death and the patient was beyond help. The longer the attack, the more damage to the heart and the greater the chance of dying. Thus a brief health information about factors that cause “.
