41
ather/oma
tumor of fatty plaque
42
arteri/o/stenosis
narrowing or stricture of an artery
43
cardi/o/logist
medical specialist in the heart (disease)
44
cardi/o/megaly
enlargement of the heart
45
electr/o/cardi/o/graphy
process of recording electrical activity of the heart
46
embol/ectomy
excision of an embolus
47
deep vein thrombosis (DVT)
formation of a thrombus, usually in calf or thigh muscle, partial or complete block of blood flow, may cause pain but often asymptomatic
48
anticoagulants
prevent future thrombi formation
49
thrombolytics
dissolve blood clots
50
coronary artery disease (CAD)
angina, shortness of breath (SOB), accumulation of plaque in arterial walls causing them to harden
51
electrocardiogram (ECG), electrocardiography (ECG)
diagnostic test to record electrical activity of the heart
52
percutaneous transluminal coronary angioplasty (PTCA)
balloon angioplasty to crush fatty deposits in the coronary vessel and improve blood flow
53
aneurysm
local dilation of an artery or chamber of the heart caused by weakening of its walls, may cause thrombus formation, hemorrhage from rupture, or ischemia
54
fusiform
dilation of entire circumference of artery spindle-shaped aneurysm
55
saccular
shaped like a sac, bulging on only one side of arterial wall
56
dissecting
inner layer tear (dissection) causes a cavity to form that fills with blood with each heartbeat
57
hypotension
low blood pressure
58
aneurys/mec/tomy
surgical procedure to excise an aneurysm
59
varicose veins
defective or incompetent valves in veins prevent blood from flowing freely toward the heart, buildup of pressure in superficial veins causes varicosities
60
sclerotherapy
a chemical injection into the varicosities to destroy and close the veins
61
pulmonary embolism
blood clot (embolism) lodges in and occludes and artery in the pulmonary vasculature
62
hemo/ptysis
spitting up blood with sputum
63
arrhythmia, dysrhythmia
irregularity or loss of rhythm of the heartbeat
64
bruit
soft blowing sound heard on auscultation caused by turbulent blood flow
65
heart block
interference with normal transmission of electrical impulses through the conducting system of the heart
66
heart failure (hf)
inability of the heart to circulate blood to meet the body's metabolic needs effectively
67
hypertension
consistently elevated blood pressure that is higher than 140/90 mm Hg causing damage to the blood vessels and ultimately the heart
68
ischemia
inadequate supply of oxygenated blood to a body part as a results of an interruption of blood flow
69
cardiac catheterization
catheter is guided into the heart via a vein or artery
70
cardiac enzymes
test to measure levels of enzymes released into the blood during a myocardial infarction (MI)
71
holter monitor
records ecg readings, usually for 24 hours, on portable tape recorder to document arrhythmias and link them to activities or to symptoms such as chest pain
72
stress test
exercise tolerance test to determine the heart's response to physical exertion (stress)
73
doppler ultrasonography (us)
used to assess blood flow through blood vessels and the heart
74
troponin 1
blood test that measures levels of proteins released into the blood when myocardial cells die (damaged heart muscle)
75
ekg ecg
recording of electrical activity of the heart
76
electrocardiogram
record of electrical (activity) of the heart
77
ather/oma
tumor (composed of) fatty plaque
78
venography, phlebography
process of recording (radiography) a vein
79
thromb/o/lysis
separation or destruction of a blood clot
80
aort/o/graphy
process of recording (radiography) the aorta
81
arteri/o/scler/osis
abnormal condition of arterial (walls) hardening
82
angi/o/graphy
process of recording (radiography) vessels (after injection of a contrast dye)
83
automatic implantable cardioverter-defibrillator (AICD)
device implanted in a patient who is at high risk for developing a serious arrhythmia
84
angi/o/plasty
any endovascular procedure that reopens narrowed blood vessels, restores blood flow, usually using balloon dilation
85
coronary artery bypass graft (CABG)
vein taken from leg or other part of the body is grafted onto the heart to circumvent an obstruction in a coronary artery
86
valv/ulo/plasty
surgical repair or replacement of a valve
87
beta blockers
decrease heart rate and dilate arteries by blocking beta receptors, treat angina pectoris and hypertension
88
nitrates
treat angina pectoris (chest pain), dilate veins, which decreases the amount of work the heart must do, dilate arteries to decrease blood pressure
89
statins
lower cholesterols levels in the blood, reduce cholesterol production the the liver, block the enzyme that produces cholesterol
