white blood cells
leukocytes
hardening and narrowing of arteries caused by buildup of plaque
arthrosclerosis
inadequate blood flow to myocardium
angina
occlusion of one or more coronary arteries due to plaque build up
myocardial infarction
inflammation of inner lining of heart
endocarditis
term to describe all diseases of myocardium
cardiomyopathy
loss of normal rhythm of heartbeat
arrhythmia
heart abruptly stops beating
cardiac arrest
contractions of atria become rapid and uncontrolled
atrial fibrillation
rapid, irregular contractions of ventricles
ventricular fibrillation
heartbeat below 60bpm
bradycardia
heart rate above 100bpm
tachycardia
localized weak spot or balloon like enlargement of wall of an artery
aneurysms
inflammation of temporal arteries
temporal arteritis
inflammation of a vein
phlebitis
abnormally swollen veins due to improper functioning of valves
varicose veins
having a thrombus
thrombosis
may be a blood clot, quantity of air or gas, or in piece of tissue or tumor
embolus
peripheral occlusive disease triggered by cold or stress
Raynaud’s disease
decrease in number of disease-fighting white blood cells
leukopenia
abnormally small number of circulating platelets
thrombocytopenia
loss of large amount of blood
hemorrhage
infection in blood stream
sepsis
cancer due to insufficient production of one or more types of blood cells
myelodyplastic syndrome
cancer characterized by progressive number of abnormal leukocytes in tissues, organs, and blood
leukemia
decreased number of erythrocytes
anemia
absence of all formed blood elements
aplastic anemia
larger than normal red blood cells
megaloblastic anemia
due to body’s inability to absorb vitamin B12
pernicious anemia
inadequate number of circulating red blood cells
hemolytic anemia
abnormal hemoglobin resulting in some red blood cells assuming sickle shape
sickle cell anemia
catheter passed into vein or artery and guided into heart
cardio catheterization
record electrical activity or myocardium
electrocardiogram
injecting thallium and assessing blood flow through coronary arteries during exercise
thallium stress test
block enzyme that causes vessels to contract
ACE inhibitor
slows heart beat
beta-blocker
increase secretion of urine to rid body of excess sodium and water
diuretic
dissolves thrombi
thrombolytic
slows coagulation
anticoagulant
surgical removal of plaque
artherectomy
removal of portion of clogged artery
carotid endarterectomy
mechanically widen obstructed vessel
angioplasty
electrical shock to restore normal rhythm
defibrillation
automatically samples rhythm and externally shocks heart if needed
automated external defibrillator
a fatty substance that travels through blood and found in all parts of the body
cholesterol
venous circulation is inadequate due to partial vein blockage or leakage of venous valves
chronic venous insufficiency
a therosclerosis of coronary arteries that reduces blood supply to the heart muscle
coronary artery disease
sudden blockage of blood vessel by an embolus
embolism
oxygen-carrying blood protein pigment in erythrocytes
hemoglobin
abnormal protrusion of a heart valve that results in inability of the valve to close completely
mitral valve prolapse
blocking of an artery by a thrombus
thrombotic occlusion
abnormal condition of having a thrombus
thrombus
serious and potentially fatal complication of blood transfusion in which severe immune response occurs because the patient’s blood and donated blood do not match
tranfusion reaction
a blood clot that originates in a vein
venous thromboembolism
very rapid heart bear that begins within the ventricles
ventricular tachycardia
