Information On Heart Disease

Heart disease is a broad term that includes several more specific heart conditions. The most common heart condition in the United States is coronary heart disease, which can lead to heart attack and other serious conditions.

Information on Heart Disease:

Coronary Heart Disease (CHD)

CHD is the most common type of heart disease. CHD occurs when the coronary arteries, that supply blood to the heart muscle, become hardened and narrowed due to the plaque buildup. The plaque buildup and the narrowing and hardening of the arteries is called atherosclerosis. Plaques are a mixture of fatty substances including cholesterol and other lipids. Blood flow and oxygen supply to the heart can be reduced or even fully blocked with a growing plaque. Plaques may also rupture and cause blood clots that block arteries.

CHD can lead to a heart attack. Angina can also occur. Angina is chest pain or discomfort that occurs when the heart muscle is not getting enough blood. Over time, CHD can weaken the heart muscle and lead to heart failure, a serious problem where the heart cannot pump blood the way that it should. Also, irregular heart beats, called arrhythmias, can develop.

The most common symptom of CHD is angina. In some people the first sign of CHD is a heart attack.

Heart Attack

A heart attack is also called a myocardial infarction. If the blood supply to the heart is severely reduced or completely blocked, heart muscle cells may not receive enough oxygen and begin to die. The more time that passes without treatment to restore blood flow, the greater the damage to the heart. This damage can cause irregular heart rhythms or even sudden cardiac arrest or stopping of the heart beat. Death can result. Coronary artery disease is the chief underlying cause of a heart attack. A less common cause of a heart attack is a severe spasm of a coronary artery that reduces the blood supply to the heart.

When a person is having a heart attack, emergency care is needed that may include cardiopulmonary resuscitation (CPR), electrical shock (called defibrillation), and other advanced emergency medical care. Emergency medical personnel and doctors can quickly perform emergency treatment and transport the person to the hospital. Bystanders might also be trained to perform CPR and to use an automated external defibrillator, if one is available, until emergency medical personnel arrive. Once at the hospital, doctors can perform several tests to quickly determine if the person is having or has had a heart attack and the best course of action to restore blood flow.

Other Conditions and Information On Heart Disease:

  • Angina
  • Acute Coronary Syndrome
  • Aortic Aneurysm and Dissection
  • Arrhythmias
  • Cardiomyopathy
  • Congenital Heart Disease
  • Heart Failure
  • Peripheral Arterial Disease (PAD)
  • Rheumatic Heart Disease
