The heart is a muscle that pumps blood throughout the body. In a heart attack (myocardial infarction), part of the heart muscle to die while not getting blood. To stay healthy, the heart needs 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 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. The stiffness is referred to as aterosklerosis. Aterosklerosis occurs if there is a buildup 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.
However, heart disease is one of the many diseases that are harmful and cause death to the sufferer. Not infrequently, the patient is out too late that he was suffering from heart disease so it is too late for diatasai. Therefore, knowing the symptoms of heart disease or trait you need to know in order to follow the treatment be done as soon as possible.
Symptoms of heart disease
1. Pain. If the muscle is not getting enough blood (a condition called ischemia), then the oxygen is inadequate and excessive metabolic cause cramps or spasms. Angina is a feeling of tightness in the chest or squeezing chest feeling, which arises when the heart muscle not getting enough blood. The type and severity of pain or discomfort varies in each person. Some people experience a lack of blood flow could not feel any pain at all (a condition called silent ischemia).
2. Shortness of breath is a common symptom in heart failure. Congested as a result of the influx of fluid into the air cavity in the lungs (pulmonary congestion or pulmonary edema).
3. Fatigue or exhaustion. If the heart is not pumping effectively, blood flow to the muscles during activity is reduced, causing the patient to feel weak and tired. These symptoms are often mild. To overcome this, the patient usually is gradually reducing its activity or thought these symptoms as part of aging.
4. Palpitations (heart palpitations)
5. dizziness and fainting. Decreased blood flow due to rate or abnormal heart rhythm or because of poor pumping ability, can cause dizziness and fainting.
