Substained abnormally high blood pressure.

A form of CVD in which the inner layers of artery wlls are made thick and irregular by plaque deposits; arteries become narrow and blood supply is reduced.

Blood fat that transports cholesterol from the liver to organs and tissues; excess is deposited on artery walls, where it can eventually block the flow of blood to the heart and brain; "bad" cholesterol

A test to detect abnormalities by evaluating the electrical activty in the heart.

An impeded blood supply to some part of the brain resulting in the destruction of brain cells; also called cerebrovascular accident.

Impeded blood supply to some part of the btain caused by the obstruction of a blood vessel by a clot.

impeded blood supplt to the brain to the brain caused by the rupture of a blood vessel.

A bloof clot in a blood bessel that usually occurs at the point of its formation.

A blood clot that breaks off from its place of origin in a blood vessel and travels through the bloodstream.

A sac formed by a distention or dilation of the artery wall.

A small stroke; usually a temporary interruption of blood supply to the brain, causing numbness or difficulty with speech.

The use of computerized X ray impages to create a cross-sectional depiction(scan) of tissue density.

A condition resulting fomr the heart's inability to pump out all the blood that returns to it; blood backs upin the veins leasing to the heart, causing an accumulation of fluid in various parts of the body.

A defect or malformation of the heart or its major bloodvessels present at birth.

An inherited condition in which there is an enlargement of the heart muscle, especially between the two ventricles.

A disease, mainly of children, characterized by fever, inflammation, and pain in the joints; often damages the heart muscle

A condition in which the miltral valve "billows' out during ventricular contraction, possibly allowing leakage of blood from the left ventricle into the left atrium; often asymptomatic and usually requiring treatment only in cases of significant leakage.

Abnormal, uncontrolled cellular growth.

A tumor that is cancerous and capable of spreading.

A tumor that is not cancerous

A system of vessels that returns proteins, lipids, and other substances form fluid in the tissue to the circulatory system.

The removal and examination of a small piece of body tissue.

The spread of cancer cells from one part of the body to another.

Any substance that cause cancer.

The treatment of cancer with chemicals that selectively destroy cancerous cells.

A period during the course of cancer in which there are no symptoms or other evidence of disease.

A section of a chromosome that contains the cucleotide base sequence for making a particular proteinl the base unit of heredity

A gene involved in the transformation of a normal cell into a cancer cell.

Any of a group of yellow-to-red plant pigments that can be converted to vitamin A by the liverl many act as antioxidants or have other anti-cancer effects.

A substance that can be lessen the breakdown of food or body constituents; actions include binding oxygen and donating electrons to free radicals
