ACE inhibitor
Blocks the action of an enzyme that causes the blood vessels to contract, resulting in hypertension.
anemia
A lower-than-normal number of erythrocytes (red blood cells) in the blood.
aneurysm
A localized weak spot or balloon-like enlargement of the wall of an artery.
angina
A condition of episodes of severe chest pain due to inadequate blood flow to the myocardium.
angioplasty
The technique of mechanically widening a narrowed or obstructed blood vessel.
anticoagulant
Medication that slows coagulation and prevents new clots from forming.
aplastic anemia
A condition characterized by the absence of all formed blood elements caused by the failure of blood cell production in the bone marrow.
arrhythmia
The loss of the rhythm of the heartbeat.
atherectomy
Surgical removal of plaque buildup from the interior lining of an artery.
atheroma
A deposit of plaque on or within the arterial wall.
atherosclerosis
Hardening and narrowing of the arteries due to a buildup of cholesterol plaque on the interior walls of the arteries.
atrial fibrillation
When the normal rhythmic contractions of the atria are replaced by rapid, uncontrolled twitching of the muscular heart wall.
automated external defibrillator
Electronic equipment that automatically samples the heart’s electrical rhythms and when necessary, externally shocks the heart to restore a normal cardiac rhythm.
beta-blocker
A medication that reduces the workload of the heart by slowing the heart rate of the heartbeat.
blood dyscrasia
Any pathologic condition of the cellular elements of the blood.
bradycardia
An abnormally slow resting heart rate.
cardiac arrest
An event in which the heart abruptly stops beating or develops arrhythmia that prevents it from pumping blood effectively.
cardiac catheterization
A diagnostic and treatment procedure in which a catheter is passed into a vein or an artery and is guided into the heart.
cardiomyopathy
The term used to describe all diseases of the heart muscle.
carotid endarterectomy
Surgical removal of the lining of a portion of a clogged carotid artery leading to the brain.
cholesterol
A fatty substance that travels through the blood and is found in all parts of the body.
chronic venous insufficiency
A condition in which venous circulation is inadequate due to partial vein blockage or leakage of venous valves.
coronary artery disease
Atherosclerosis of the coronary arteries that reduces blood supply to the heart muscle.
coronary thrombosis
Damage to the heart muscle caused by a thrombus blocking a coronary artery.
defibrillation
The use of electrical shock to restore the heart’s normal rhythm; also known as cardioversion.
diuretic
Medication administered to stimulate the kidneys to increase the secretion of urine to rid the body of excess sodium and water.
electrocardiogram
A record of electrical activity of the myocardium.
embolism
The sudden blockage of a blood vessel by an embolus.
embolus
A foreign object, such as a blood clot, quantity of air or gas, or a bit of tissue or tumor, that is circulating in the blood.
endocarditis
Inflammation of the inner lining of the heart.
erythrocytes
Mature red blood cells produced by the red bone marrow.
hemoglobin
The oxygen-carrying blood protein pigment of the erythrocytes.
hemolytic anemia
A condition of an inadequate number of circulating red blood cells due to the premature destruction of these cells by the spleen.
hemostasis
To stop or control bleeding.
leukemia
A type of cancer characterized by a progressive increase in the number of abnormal leukocytes (white blood cells) found in blood-forming tissues, other organs, and in the circulating blood.
leukocytes
White blood cells that are involved in defending the body against infective organisms and foreign substances.
leukopenia
A decrease in the number of disease-fighting white blood cells circulating in the blood.
megaloblastic anemia
A blood disorder characterized by anemia in which red blood cells are larger than normal.
myelodysplastic syndrome
A type of cancer in which there is insufficient production of one or more types of blood cells due to dysfunction of the bone marrow.
myocardial infarction
The occlusion (blockage) of one or more coronary arteries caused by plaque buildup; commonly known as a heart attack.
orthostatic hypotension
Low blood pressure that occurs upon standing up; also knwon as postural hypotension.
pericardium
The double-walled membranous sac that encloses the heart.
pernicious anemia
A form of anemia by a lack of the protein that helps the body absorb vitamin B12, which is necessary for thr formation of red blood cells.
phlebitis
Inflammation of a vein.
Raynaud’s disease
A peripheral arterial occlusive disease in which intermittent attacks are triggered by cold or stress.
sepsis
A potentially life-threatening infection that results from bacteria or other infectious organisms entering the bloodstream.
sickle cell anemia
A genetic disorder that causes abnormal hemoglobin, resulting in some red blood cells assuming an abnormal sickle shape that interferes with normal blood flow.
tachycardia
An abnormally rapid resting heart rate.
temporal arteritis
A form of vasculitis that can cause headaches, visual impairment, jaw pain, and other symptoms.
thallium stress test
A diagnostic test performed to evaluate how well blood flows through the coronary arteries of the heart muscle during exercise.
thrombocytopenia
A condition in which there is an abnormally small number of platelets circulating in the blood.
thrombolytic
Medication that dissolves or causes a thrombus to break up; also known as a clot-busting drug.
thrombosis
The abnormal condition of having a thrombus.
thrombotic occlusion
The blocking of an artery by a thrombus.
thrombus
A blood clot attached to the interior wall of a vein or artery.
transfusion reaction
A serious and potentially fatal complication of a blood transfusion in which a severe immune response occurs because the patient’s blood and the donated blood do not match.
valvulitis
Inflammation of a heart valve.
varicose veins
Abnormally swollen veins, usually occurring in the superficial veins of the legs.
ventricular fibrillation
The rapid, irregular, and useless contractions of the ventricles.
ventricular tachycardia
A very rapid heartbeat that begins within the ventricles.
