anemia
pathological decrease of red cells, causes weakness and fatigue
aneurysm
widening of blood vessels and weakening of the vessel wall
angina pectoris
chest pain caused by insufficient blood flow to heart muscle
antibody
substance produced by body due to presence of an antigen
antigen
substances that causes the body to produce antibodies
aortic regurgitation
backflow of blood from aorta into heart; cause by weak heart valve
arrhythmia
abnormal rate or rhythm of heart beat
atherosclerosis
narrowing of arteries due to buildup of fatty plaques
atrial fibrillation
quivering or spontaneous contraction of atria, aka a-fib
autoimmune disease
when immune system attacks normal body cells/tissues
automatic external defibrillator
portable electronic device, automatically diagnoses life-threatening arrhythmia’s, delivers electrical chock to restore normal rhythm
bradycardia
abnormally slow heart rate
cardiac arrest
cessation of heart contraction and blood circulation
coagulopathy
impaired ability of blood to clot
congestive cardiomyopathy, congestive heart failure
heart chambers inability to fill/empty adequately, heart wall becomes stretched/weak
coronary artery bypass graft
borrowed piece of blood vessel to bypass narrowed or blocked coronary artery and improve blood supply to heart muscle
coronary artery disease
atherosclerosis of coronary arteries, insufficient oxygen to heart muscle, cause angina pectoris
cyanosis
bluish color to skin/mucus membrane caused by insufficient blood flow or insufficient oxygen in blood
deep vein thrombosis
formation of blood clot located in deep veins of the body, usually in lower extremity
ecchymosis
discoloration of skin caused by bruising
embolism
an embolus that lodges in and blocks a blood vessel
embolus
any matter that forms in circulation (air bubble, blood clot, plaque, fat)
hemophilia
blood doesn’t clot due to hereditary lack of blood clotting factor(s)
hypertension
abnormally high blood pressure
immunocompromised
an immune system that does not respond normally or completely to a pathogen or disease
ischemia
insufficient blood flow to any body part/tissue/organ
leukemia
cancer of blood flow or marrow, marked increase of white blood cells
malaise
vague feeling of general body discomfort, may be first indication of infection or disease
mononucleosis
disease caused by Epstein-Barre virus, transmitted through saliva, characterized by fatigue, rash, swollen glands
murmur
abnormal heart sound due to inability of heart valves to close completely during contractions
myocardial infarction
death of heart muscle area due to lack of blood flow, aka heart attack
cardiopulmonary bypass
temporarily circulation/oxygenation of patient’s blood by machine during open heart surgery
cardiopulmonary resuscitation
basic life support
cardiotonic
medication that increases strength of heart contractions
cardioversion
return heart to normal cardiac rhythm by delivering brief electrical discharge across chest
coronary circulation
circulation of blood from heart to itself via coronary arteries
diastolic pressure
pressure exertion on blood vessels that binds oxygen and gives red blood cells red color
immunoblobulin
protein produced by white cells to fight invaders, aka antibody
leukocyte
white blood cell
lymph node
clusters of lymphatic tissue, filter pathogens, and cancer cells from lymphatic, full of white blood (immune) cells
percutaneous coronary intervention
treatment for coronary artery disease, passes instruments up patient’s blood vessel into heart, aka angioplasty
phagocytosis
when phagocyte (white blood cells) “eats” (engulfs) something
phelbotomy
surgically open/puncture vein to withdraw blood or introduce tx
platelet
cell fragment involved in blood clotting
sclerotherapy
varicose vein treatment; chemical injection into varicose vein to cause inflammation, form fibrosis tissue, and close vein
sphygmomanometer
equipment used to measure blood pressure
stress electrocardiogram
image of heart produced by sound waves while patient increases physical stress during exercise
stroke volume
volume of blood ejected from heart with each contraction
systolic pressure
pressure exerted on blood vessels when heart is contracted
