Heart Attack

Every year, nearly 800,000 Americans are suffering from heart attacks. A heart attack occurs when blood flowing to the heart is abruptly blocked. If blood does not enter, the heart can not get oxygen. If left untreated, myocardium begins to die. However, if you get prompt treatment, you can prevent or limit your heart muscle damage. That is why it is important to know the symptoms of a heart attack. If you and others have this symptom, please call 9-1-1. Even if you do not know if it is a heart attack, you need to call

Chest discomfort. Usually it is on the center or on the left side of the chest. It usually lasts more than a few minutes. It may disappear and come back. It can feel like pressure, compression, plumpness or pain. Heartburn and indigestion may also be felt

Shortness of breath Occasionally this is your only symptom. It may develop before or during chest discomfort. This happens when you take a break or do some physical activity.

Discomfort of the upper body. You may feel pain or discomfort in one or both arms, back, shoulder, neck, chin, or upper stomach.

There may be other symptoms such as nausea, vomiting, dizziness, dizziness. You may get up for a cold sweat. Women may show different symptoms from men. For example, they are likely to feel tired without a reason.

The most common cause of heart attack is coronary artery disease (CAD). In CAD, cholesterol and other substances called plaque accumulate in the inner wall and artery. This is atherosclerosis. It can accumulate for many years. Eventually the plaque area may rupture (fracture). A thrombus forms around the plaque and may block the artery

A less common cause of heart attacks is severe coronary spasms (tightening).遮断 Block blood flow in arteries

In hospitals, healthcare workers will diagnose based on your symptoms, blood tests, and various cardiac health examinations. Treatment may include drug therapy such as coronary angioplasty and medical procedures. Cardiac recovery and lifestyle changes can help restore after a heart attack

Even though the words "heart attack" or "large-scale heart attack" are used, sudden cardiac arrest is not a heart attack. When part of the blood flow in the heart slows down or stops, one plaque of the coronary artery ruptures and usually a heart attack occurs. This can lead to myocardial death. But heart attacks do not necessarily mean that the heart stops beating. Heart attacks can lead to SCA, but the two terms do not mean the same thing. Most SCA cases are caused by a very fast heart rate (ventricular tachycardia) or a very confusing heart rate (ventricular fibrillation). These irregular heart rhythms, called arrhythmias, may stop heart beating. Another type of arrhythmia called bradycardia has a very slow heart rate and can also cause SCA.

Heart Attack When a heart attack occurs, it is usually due to severe coronary artery disease, which can cause ventricular fibrillation and cardiac arrest. In addition, heart attacks may leave areas of scar tissue. Electrical shorts around the scar tissue can cause abnormal heart rhythms. If you live with a person prone to cardiac arrest, you need to be trained in cardiopulmonary resuscitation. The American Red Cross and other organizations offer courses to the general public about cardiopulmonary resuscitation and the use of defibrillators. Getting training is helpful not only to the people you love, but also to the local people. The more people know how to deal with cardiac emergencies, the higher the survival rate of cardiac arrest.

These two different heart diseases are related. Cardiac arrest may occur after cardiac arrest or recovery. Heart attacks increase the risk of cardiac arrest. Most heart attacks do not cause cardiac arrest. However, when cardiac arrest occurs, a heart attack is a common cause. Other heart diseases can disturb the rhythm of the heart and cause cardiac arrest. These include thickened myocardium (cardiomyopathy), heart failure, arrhythmia, especially ventricular fibrillation, Q-T prolonged syndrome
