A problem that prevents the heart from working normally. This problem can be with the heart's shape or how the heart works, or with the blood vessels supplying the heart.

Heart disease is any disorder that affects the heart's ability to function normally. The most common cause of heart disease is narrowing or blockage of the coronary arteries, which supply blood to the heart.

Heart disease takes many forms. Usually, heart disease occurs due to inadequate blood flow to the hear muscle. This occurs when the arteries that supply the heart muscle (the coronary arteries) become partially or completely blocked. Obese people are at increased risk of heart disease due to their higher rates of hypercholesterolemia, diabetes and hypertension.

any affliction that impairs the structure or function of the heart (e.g., atherosclerotic and hypertensive diseases, congenital heart disease, rheumatic heart disease, and cardiomyopathies).

also known as atherosclerosis, or hardening of the arteries, characterized by fat, cholesterol, and calcium deposits and blockages of the blood vessels.

Progressive damage to the heart and the blood vessels that supply it, caused by disease processes that are associated with poor diet and a sedentary lifestyle.

caused by a range of factors, from controllable ones like diet, activity and smoking to age, gender, ethnicity and heredity. It's likely to produce angina pectoris (chest pain), heart attack or both.

see Coronary heart disease

Coronary artery disease, the most common type of heart disease, happens when the heart doesn't get enough blood.

Diseases of the heart. These include conditions that affect the heart's valves and muscle. (Read about " The Heart & Cardiovascular System" " The Heart and Its Valves")

Heart disease refers to any disease or condition of the heart, including coronary heart disease, heart failure, hypertensive heart disease, congenital heart disease, disorders of the heart valves, infections of the heart, cardiomyopathy, conduction disorders, and rhythm disorders.

a condition in which the heart cannot efficiently pump blood. Coronary artery disease is the most com­ mon form of heart disease. It occurs when the arteries that nourish the heart muscle narrow or become blocked. People with diabetes have a higher risk than the gener­al population of developing heart disease. Hyperglycemia: a condition in which blood glucose levels are too high. Symp­ toms include frequent urination, increased thirst, and weight loss. Hypoglycemia: (or insulin reaction) a condition in which blood glucose levels drop too low (generally, below 70 mg/dl). Symptoms include moodiness, numbness in the arms and hands, confusion, and shakiness or dizziness. When left untreat­ ed, this condition can become severe and lead to unconsciousness.

Also called coronary artery disease (CAD). A condition in which the arteries that service the heart are narrowed by LDL-deposited plaques. When an artery becomes blocked and bloodflow is impeded, the heart muscle is deprived of oxygen. Blocked bloodflow can cause chest pain (also called angina) and/or heart attack. High levels of LDL cholesterol can indicate heart disease.

Heart Disease is a structural or functional abnormality of the heart, or of the blood vessels supplying the heart, that impairs its normal functioning. Heart disease describes a variety of disorders and conditions that can affect the heart. The most common type of heart disease is coronary heart disease (CHD), also called coronary artery disease (from WebMD).

Any disorder that affects the heart. Sometimes the term "heart disease" is used narrowly and incorrectly as a synonym for coronary artery disease. Heart disease is synonymous with cardiac disease but not with cardiovascular disease which is any disease of the heart or blood vessels. Among the many types of heart disease, see, for example: Angina; Arrhythmia; Congenital heart disease; Coronary artery disease ( CAD); Dilated cardiomyopathy; Heart attack ( myocardial infarction); Heart failure; Hypertrophic cardiomyopathy; Mitral regurgitation; Mitral valve prolapse; and Pulmonary stenosis.

heart disease - malignant pleural mesothelioma.

A type of arteriosclerosis involves deposits of fatty substances, calcium, and fibrin in the inner lining of the coronary artery.

Any of a number of diseases related to the heart and blood vessels. Also known as coronary artery disease. When grouped together, these diseases are the leading cause of death in the United States.

A condition that affects the heart muscle or the blood vessels of the heart.

Generally, injury to heart muscle and/or conducting system due to decreased blood flow from coronary artery disease.

A general term for high blood pressure and/or the narrowing of arteries supplying blood to the heart; the most common cause of death in the United States.

Heart disease is an umbrella term for a number of different diseases which affect the heart.
