angiography
radiographic imaging of blood vessels (the procedure is named for the vessel to be studied, e.g., femoral angiography or coronary angiography)
angioscope
instrument used for visual examination (of the lumen) of a blood vessel
angioscopy
visual examination (of the lumen) of a blood vessel
aortogram
radiographic image of the aorta (after an injection of contrast media)
arteriogram
radiographic image of an artery (after an injection of contrast media)
blood pressure
pressure exerted by the blood against the blood vessel walls.

C-reactive protein (CRP)
a blood test to measure the amount of C-reactive protein in the blood, which, when elevated, indicates inflammation in the body
cardiac catheterization
an examination to determine the condition of the heart and surrounding blood vessels. A catheter is passed into the heart through a blood vessel and is used to record pressures and inject a contrast medium, enabling the visualization of the coronary arteries, great vessels and the heart chambers.
creatine phosphokinase (CPK)
a blood test used to measure the level of creatine phosphokinase, an enzyme of heart and skeletal muscle released into the blood after muscle injury or necrosis.
digital subtraction angiography (DSA)
a process of digital radiographic imaging of the blood vessels that “subtracts” or removes structures not being studied
Doppler ultrasound
a study that uses sound for detection of blood flow within the vessels; used to assess intermittent claudication deep vein thrombosis, and other blood flow abnormalities
echocardiogram (ECHO)
record of the heart (structure and motion) using sound (used to detect valvular disease and evaluate heart function)
electrocardiogram (ECG, EKG)
record of the electrical activity of the heart
electrocardiograph
instrument used to record the electrical activity of the heart
electrocardiography
process of recording the electrical activity of the heart
exercise stress test
a study that evaluates cardiac function during physical stress by riding a bike or walking on a treadmill. Electrocardiography, echocardiography, and nuclear medicine scanning are three types of tests performed to measure cardiac function while exercising.
homocysteine
a blood test used to measure the amount of homocysteine in the blood. Homocysteine is an amino acid that, if elevated, may indicate an increased risk if cardiovascular disease.
impedance plethysmography (IPG)
measures venous flow of the extremities with a plethysmograph to detect clots by measuring changes in blood volume and resistance (impedance) in the vein; used to detect deep vein thrombosis
lipid profile
a blood test used to measure the amount of lipids in sample of blood. This test issued to evaluate the risk of developing cardiovascular disease and to monitor therapy of existing disease.
pulse
the rhythmic expansion of an artery that can be felt with a finger. The pulse is commonly felt over the radial artery, but can be felt over a number o sites.
single-photon emission computed tomography (SPECT)
a nuclear medicine scan that visualizes the heart from several different angles. A radioactive tracer substance such as sestamibi or thallium is injected intravenously. The SPECT scanner creates images from the tracer absorbed by the body tissues. It is used to assess damage to cardiac tissue
sphygmomanometer
device used for measuring blood pressure.
thallium test
a nuclear medicine test used to diagnose coronary artery disease and assess revascularization after coronary artery bypass surgery. Thallium, a radioactive isotope, is injected into the body intravenously; a radiation detector is placed over the heart and images are recorded. Thallium is taken up by the normal myocardial cells, but not in ischemia or infarction . The areas are identified as “cold” spots on the images produced.
transesophageal echocardiogram (TEE)
an ultrasound test that examines cardiac function and structure by using an ultrasound probe placed in the esophagus which provides views of the heart structures
troponin
a blood test that measures troponin, a heart muscle enzyme The test is useful in the diagnosis of myocardial infarction
venogram
a radiographic image of a vein (after an injection of contrast media)
venography
radiographic imaging of a vein (after an injection of contrast media)
coagulation time
blood test to determine the time it takes for blood to form a clot
complete blood count and differential (CBC and Diff)
basic blood screening that measures hemoglobin, hematocrit, red blood cell number and morphology (size and shape), leukocyte count, and white blood cell differential (types of white blood cells) and platelet count.
hematocrit (HCT)
a blood test to measure the volume of red blood cells. It is used in the diagnosis and evaluation of anemic patients.
hemoglobin (Hgb)
blood test used to determine the concentration of oxygen-carrying components (hemoglobin) in red blood cells
prothrombin time
blood test used to determine certain coagulation activity defects and to monitor anticoagulation therapy for patients taking Coumadin, an oral anticoagulant medication. (Activated partial thromboplastin time [PTT] is used to monitor anticoagulation therapy for patients taking heparin, an intravenous anticoagulant medication.)
