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 requires oxygen and other nutrients carried by blood. This is obtained through the artery (blood vessel) disease, which wrap the outside of the heart.-
Heart Attack
Most diseases can affect any part of the heart. However, the most common disease is a chronic disease in the coronary artery is called atherosclerosis. Therefore, heart disease commonly known and most common is coronary heart disease or coronary artery disease. The disease is 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. The narrowing is caused by a pile of cholesterol or other proteins derived from food intake in the body. This buildup causes the coronary arteries become stiff. Rigidity is referred to as atherosclerosis.
Atherosclerosis occurs when the buildup of plaque or fatty deposits in artery walls. Over 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.
Even in the arteries that are not too narrow because of plaque and fatty deposits, deposits 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 of 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 heart rhythm can become chaotic and the heart began to tremble with uncertainty 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 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, heart valve disorders, weakened heart muscle. Another cause is the bacteria that cause infections of the heart.-
Symptoms of Heart Attack
The symptoms are perceived if you have coronary heart disease include pain or pain in the chest in which 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 thing is the cold sweat, palpitations, dizziness, and felt like fainting. These symptoms are not always perceived sufferer. Another warning sign is gasping for breath during exercise. For several months before the heart attack usually people with heart disease often feel very tired. Do not assume these symptoms are caused by lack of sleep and stress of the job.
Pain or feeling of pressure in the chest, called Angina, give warning to half of those who suffer a heart attack. Some people get breathless or exhausted and feeling weak as the symptoms, indicating that the heart is not getting enough oxygen due to blockage of a coronary.
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 occur before a major attack a few days later.-
Tips for Preventing Heart Attack
To reduce risk of coronary heart attack, you can do the following things:
- Healthy diet. Avoid foods that contain lots of fat or high cholesterol. Seafood contains high cholesterol that can harm the heart. Reduce eating fried foods that contain lots of fat, otherwise the food can be processed by boiling, steaming or roasting. Apart from avoiding fatty foods, avoid foods with sugar content is also high, such as soft drinks. Do not consume too many carbohydrates, because in the body, carbohydrates are broken down into fat. In contrast, consumption of oats or wheat that can help keep the heart healthy.
- Stop smoking. Cigarette is not good for heart health, then immediately stop this practice for heart stay healthy.
- Avoid Stress. Stress is very difficult to avoid when living in big cities are known for traffic jams and daily activity is very high. When a person experiences stress, the body will release the hormone Cortisol, which causes the blood vessels become stiff. Hormone Norepinephrine produced by the body when suffering from stress, which will result in increased blood pressure. So, very good if you avoid the stress both in the office or at home.
- Hypertension. Problem hypertension or high blood pressure can also cause heart disease. Hypertension can injure the arterial wall and allows the channel to enter the arterial LDL cholesterol and increase the accumulation of plaque.
- Obesity. Overweight or obese increases the high blood pressure and abnormal fat. Avoiding or treating obesity or obesity is the main way to avoid diabetes. Diabetes accelerate coronary heart disease and increased risk of heart attack.
- Exercise regularly. You can do sports activities such as walking, brisk walking, or jogging. Sporting activities which are neither too much competition and not to strengthen the work of the heart and blood circulation throughout the body.
- Consumption of antioxidants. Air pollution, motor vehicle fumes or cigarette smoke create the emergence of free radicals in the body. Free radicals can cause ulcers or deposition of the arteries that can cause blockages. To remove the content of free radicals in the body, there needs to be an antioxidant that will catch and throw. Antioxidants can be obtained from a variety of fruits and vegetables.
- Inherited from parents. A person who is a parent or sibling had suffered a heart attack before age 60 have a greater risk of suffering from this disease. Therefore, if you have relatives who have had a heart attack, you should be more careful in keeping to your diet and your lifestyle to support a healthy heart.
