Angina is chest pain or discomfort that occurs when an area of your heart muscle doesn't get enough oxygen-rich blood. Angina is usually a symptom of coronary artery disease, the most common type of heart disease.
Heart Valve Disease is a condition in which one or more of your heart valves do not work properly. The heart has four valves: the tricuspid, pulmonary, mitral, and aortic valves. These valves have tissue flaps that open and close with each heartbeat. The flaps make sure blood flows in the right direction through your heart's four chambers and to the rest of your body.
An Arrhythmia is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. Atrial fibrillation is the most common type of arrhythmia.
Atrial fibrillation is the most common type of arrhythmia.
Cardiomyopathy refers to diseases of the heart muscle. These diseases have a variety of causes, symptoms, and treatments. In cardiomyopathy, the heart muscle becomes enlarged, thick, or rigid. In rare cases, the muscle tissue in the heart is replaced with scar tissue.
Congenital Heart Defects are problems with the heart's structure that are present at birth. These defects can involve:
Congenital heart defects change the normal flow of blood through the heart.
Coronary Artery Disease, also called coronary heart disease, is a condition in which plaque builds up inside the coronary arteries. These arteries supply your heart muscle with oxygen-rich blood. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. When plaque builds up in the arteries, the condition is called atherosclerosis.
Heart Failure is a condition in which the heart cannot pump blood the way it should. In some cases, the heart can’t fill with enough blood. In other cases, the heart can’t send blood to the rest of the body with enough force. Some people have both problems.
Inherited Cardiovascular Disease – If you or someone in your family has a history of coronary artery disease, diabetes, hypertension, or obesity, you could be prone to cardiovascular disease.
Pulmonary Hypertension (PH) is increased pressure in the pulmonary arteries. These arteries carry blood from your heart to your lungs to pick up oxygen. PH causes symptoms such as shortness of breath during routine activity (for example, climbing two flights of stairs), tiredness, chest pain, and a racing heartbeat.
