Coronary Spasm
|
|
Coronary SpasmDuring coronary spasm, the coronary arteries restrict or spasm on and off, causing lack of blood supply to the heart muscle. It may occur at rest and can even occur in people without significant coronary artery disease.
RELATED TERMS--------------------------------------
Spasm
A condition in which a muscle or group of muscles involuntarily contract.
Arteries
Blood vessels that carry blood away from the heart to the arms, legs, head, body and organs.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.
Muscle
Tissue made up of bundles of long, slender cells that contract when stimulated.
Artery
A blood vessel that carries blood from the heart to the body.
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.

Corona Regional Medical Center
The Corona Regional Medical Center is a hospital in Corona, California, United States.
Coronal
A coronal plane through the body is a vertical plane from head to foot and parallel to the shoulders.
Coronary angiography
"The most accurate method (the ""gold standard"") for evaluating and defining coronary artery disease (CAD). Coronary angiography is used to identify the exact location and severity of CAD. "
Coronary Angiography (Cardiac Catheterization)
A procedure that allows picture to be taken of the arteries supplying the heart with blood (the coronary arteries). Angiography shows blockages in the arteries.
Coronary arteries
Two arteries that come from the aorta to provide blood to the heart muscle.
Coronary Arteries
Network of blood vessels that branch off the aorta to supply the heart muscle with oxygen-rich blood. There are two main coronary arteries: the right and the left. The left splits into two arteries called the circumflex and the left anterior descending (LAD) arteries, thus, the heart is often considered to have three major coronary arteries.
Coronary artery brachytherapy
Local radiation treatment within an artery to the heart. Coronary artery brachytherapy has been used to reduce the recurrence of blockage (obstruction) of a coronary artery after successful treatment of a blockage of a stent. A stent is a tubular structure that is implanted inside of a coronary artery to keep it open, thereby preventing a heart attack.
Coronary artery bypass graft
Abbreviated CABG. A form of bypass surgery that can create new routes around narrowed and blocked coronary arteries, permitting increased blood flow to deliver oxygen and nutrients to the heart muscle. CABG is an option for selected groups of patients with significant narrowings and blockages of the heart arteries. The bypass graft for a CABG can be a vein from the leg or an inner chest-wall artery. CABG surgery is one of the most commonly performed major operations. Coronary artery disease develops because of hardening of the arteries (atherosclerosis) that supply blood to the heart muscle. Diagnostic tests prior to (and after) CABG include the electrocardiogram (EKG), stress test, echocardiogram, and coronary angiography.
Coronary artery bypass graft (CAB or CABG)
A surgical procedure in which a healthy blood vessel is transplanted from another part of the body into the heart to replace or bypass a diseased vessel.
Coronary artery disease
A major cause of illness and death, coronary artery disease (CAD) begins when hard cholesterol substances (plaques) are deposited within a coronary artery.
Coronary Artery Disease (atherosclerosis)
A build-up of fatty material in the wall of the coronary artery that causes narrowing of the artery.
Coronary artery spasm
A sudden closing of an artery, which cuts off blood flow to the heart and causes symptom of angina or heart attack.
Coronary bypass
A bypass of a plaque within a coronary artery using part of a vein as a graft.
Coronary Disease
Damage to the heart. Not enough blood flows through the vessels because they are blocked with fat or have become thick and hard; this harms the muscles of the heart. People with diabetes are at a higher risk of coronary disease.
Coronary heart disease
A condition in which the coronary arteries narrow from an accumulation of plaque (atherosclerosis) and cause a decrease in blood flow.
Coronary insufficiency
Insufficient blood flow through one or more coronary arteries.
Coronary occlusion
An obstruction of one of the coronary arteries that decreases flow to the heart muscle.
Coronary thrombosis
Thrombosis is the formation of a clot or thrombus inside a blood vessel, obstructing the flow of blood through the circulatory system. Thromboembolism is a general term describing both thrombosis and its main complication: dislodgement of a clot and embolisation.
Coronary thrombosis
The formation of a clot in one of the arteries that carry blood to the heart muscle.
Coronation Hospital and Care Centre
The Coronation Hospital and Care Centre is a hospital in Oyen, Alberta, Canada.
Coronavirus
One of a group of RNA viruses, so named because they look like a corona or halo when viewed under the electron microscope. The corona or halo is due to an array of surface projections on the viral envelope.
PREVIOUS AND NEXT TERMS--------------------------------------
Connective Tissue Disease
Disease caused by problem with collagen (the elastic support system in the body); can have a vascular component. Examples include Systemic Lupus Erythematosus (SLE), rheumatoid arthritis (RA). Can also be referred to mixed connective tissue diseases (MCTD)
Constrictive Pericarditis
The pericardium is the sac around the heart. In some patients, this sac can become inflamed and scarred. If this scarring process produces a contracture or shrinkage of the pericardium, it can prevent the heart from filling to its full extent. This disease is known as constrictive pericarditis.

Coronary Spasm
Cyclosporine Level Test
A blood test that measures the amount of cyclosporine in the blood. Based on the amount of cyclosporine measured, a physician decides what dose of cyclosporine is appropriate for a patient.
C (cytosine)
C stands for cytosine, a DNA nucleotide that which is one member of the base pair in DNA consisting of guanine and cytosine. This base pair is conventionally abbreviated G-C (or GC).
C-IBS
Constipation-predominant IBS (irritable bowel syndrome).
C-peptide
A byproduct of insulin production, usually by the pancreas. The level of C-peptide is a gauge of how much insulin is being produced in the body.
C-section
Short for Caesarian section, a procedure in which a baby, rather than being born vaginally, is surgically extracted (removed) from the uterus.
