Cardiovascular Disease Medical disorders that affects the heart and blood vessels. The heart and blood vessels are two key parts of the Circulatory system.
Blood Pressure The force of blood against the walls of the blood vessels as bood flows through the circulatory system.
Hypertension If a person's blood pressure stays above his/her normal range, they have Hypertension (High Blood Pressure). Hypertension is known as the "Silent Killer".
Arteriosclerosis A condition in which the walls of the arteries become thick and lose their elasticity. Also known as "Hardening of the Arteries". Caused by poor food choices. Hypertension is a factor as well.
Athersclerosis When fatty deposits, called plaque, develop blood vessels narrow, and this can also block the arteries. HIgh fat foods and high cholesterol foods cause this.
Angina Pectoris A pain and tightness in the chest caused by the lack of oxygen to the heart.
Fibrillation The rapid ineffective beating of the heart in one of the two chambers called ventricles. Ventricular fibrillation is also known as "Cardiac Arrest".
Cardiopulmonary Resuscitation (CPR) A manual pump (Compressions) to revive the heart.
Homocysteine A potentially deadly amino acid seen in the blood in people with heart disease.
Congestive Heart Failure A slow, gradual weakening of the heart muscle from overwork.
Stroke An arterial blockage in the brain. An interruption of the flow of blood to any part of the brain.
Thrombus The blocking of a cerebral artery by a blood clot.
Cerebral Hemorrhage When a diseased artery in the brain bursts and floods the surrounding brain tissue with blood.
Electrogardiogram (EKG) Produces a graph of the electrical activity of the heart's rhythm.
Radionuclide Imaging Injection of substances called radionuclides into the blood so Technicians can check for heart damage.
Phonocardiography A process that involves placing a microphone on a person's chest to record heart sounds and signals, which are transferred through photography to graph paper.
Coronary Angiography A procedure that is used to help evaluate the extent of coronary artery disease. A catheter with dye is used to create motion X rays to detect heart blockage.
Artificial Pacemaker Something that is implanted into the chest and wired to the heart when the natural heart fails.
Magnetic Resonance Imaging (MRI) A test that uses powerful magnets to look inside the heart muscle so that technicians can look at a computer and identify heart damage.
Heart transplant A replaced damaged heart, with a healthy one from someone who recently passed away.
Coronary Bypass Surgery Creates detours around the obstructed or narrowed coronary arteries so that more blood can reach the heart using a large vein from the patient's leg.
Ballon Angioplasty A process that involves threading a balloon-tipped catheter through the body to the site of the blockage. As the balloon is inflated, it clears a path for the blood to flow through.
Heart valve surgery A surgical procedure that replaces a defective valve with an artificial one made of metal or plastic.
Tumors Masses of tissue. Not all Tumors are Cancer.

Carcinogen A cancer-causing substance in the environment.
Carcinomas Cancer that begins in the epithelial tissue, skin and tissue that line the body's organs.
Sarcomas Cancers that develop in connective and supportive tissue such as bones, muscles, and tendons.
Lymphomas Cancers that develop in the Lymphatic System, the system that drains tissue fluid back into the bloodstream and it also fights infection.
Biopsy A lab analysis of a section of tissue is taken from where abnormal growth is suspected. Ultrasound, which uses sound waves, can locate abnormal growths.
Surgery Used to remove tumors and affected surrounding areas.
Radiation Energy from cobalt or radium can penetrate a tumor. The energy destroys the tumor cells by damaging the DNA (genetic material) in the nuclei.
Chemotherapy Use of anti-cancer medications in the treatment of cancer. The goal is to destroy malignant cells without excessive destruction of normal cells.
Disability Any physical or mental impairment that limits normal activities including: seeing, hearing, walking, and speaking.
Profound deafness A hearing loss so severe that a person affected cannot benefit from a hearing aid.
Mental Retardation A below average intellectual ability present from birth or early childhood and associated with learning and social difficulties.
