BNP test
|
measurement of the brain natriuretic peptide in blood, elevated in patients with heart failure - quickly diagnoses CHF
|
|
cardiac biomarkers
|
chemicals troponin-I(cTnI) and troponin-T (cTnT) are measured in the blood as evidence of a heart attack.
|
|
lipid tests (lipid profile)
|
measurement of cholesterol of triglycerides (fats) in a blood sample. High levels associated with atherosclerosis
|
|
lipoprotein electrophoresis
|
combinations of fat and protein are physically separated and measured in a blood sample.
|
|
LDL
|
low-density lipoprotein - high levels are associated with atherosclerosis
|
|
HDL
|
high-density lipoprotein - high levels protect adults from atherosclerosis. levels increased by estrogen, exercise and alcohol in moderation
|
|
angiography
|
xray of blood vessels after injection of contrast material
|
|
arteriography
|
x-ray imaging of arteries after injection of contract via catheter into the aorta or an artery
|
|
CTA
|
computed tomography angiography - 3D xray images of the heart and coronary arteries
|
|
DSA
|
digital subtraction angiography - video equipment and a computer produce x-ray images of blood vessels before and after contrast is injected - difference image is created
|
|
EBCT or EBT
|
electron beam computed tomography
|
|
EBCT or EBT (def.)
|
electron beams and CT identify calcium deposits in and around coronary arteries to diagnose early CAD
|
|
coronary artery calcium score
|
ultrafast CT takes a clear picture of coronary arteries wile the heart is beating. Over 400 is high risk, over 100 is intermediate risk.
|
|
Doppler ultrasound studies of the cardiovascular system
|
sound waves measure blood flow within blood vessels
|
|
Duplex ultrasound
|
combines doppler and conventional ultrasound to allow for image and bloodflow exam - shows artery disorders (occlusion, vericose, aneurysm)
|
|
ECHO
|
echocardiography
|
|
echocardiography
|
echoes generated by high-frequency sound waves produce images of the heart, show structure and movement of heart
|
|
TEE
|
transesophageal echocardiography
|
|
transesophageal echocardiography
|
a transducer placed in the esophagus provides ultrasound and doppler info, detects cardiac masses, prosthetic valve function, aneurysms, and pericardial fluid
|
|
PET
|
positron emission tomography scan
|
|
PET scan
|
images show blood flow and myocardial function following uptke of radioactive glucose. dectects CAD, myocardial function, ischemic heart disease and cardiomyopathy
|
|
technetium Tc 99m sestamibi scan
|
radioactive tracer compound is taken up in heart muscle, then scanned to show damaged tissue after MI
|
|
thallium 201 scan
|
concentration of radioactive __________ is measured to give information about blood supply to the heart
|
|
Name 4 lab cardiovascular tab tests
|
BNP test
cardiac biomarkers lipid tests (lipid profile) lipoprotein electrophoresis |
|
Name 4 x-rary and electron beam tests for the cardiovascular system
|
angiography; computed tomography angiography; digital subtraction angiography; electron beam computed tomography
|
|
Name 4 ultrasound examinations of the heart
|
doppler ultrasound studies; duplex ultrasound; echocardiography; transesophageal echocardiography
|
|
name 3 nuclear cardiology tests
|
positron emission tomography scan; technetium Tc 99m sestamibi scan; thallium 201 scan
|
|
Name 6 Diagnostic procedures
|
cardiac MRI; cardiac MRA; cardiac catheterization; electrocardiography; Holter monitoring; stress test
|
|
cardiac MRI
|
images of the heart are produced using radiowave energy in a magnetic field - shows aneurysms, cardiac output and patency of arteries
|
|
cardiac MRA
|
cardiac magnetic resonance angiography - gives highly detailed images of blood vessels - shows blockage inside arteries
|
|
cardiac catheterization
|
thin, flexible tube is guided into the heart via blood vessel, for detecting pressures and patterns of blood flow - used in PCI
|
|
electrocardiography
|
recording of electricity flowing through the heart
|
|
telemetry
|
electronic transmission of data
|
|
Holter monitoring
|
An ECG device is worn during a 24 hour period to detect cardiac arrhythmias
|
|
stress test
|
exercise tolerance test determines the heart's response to physical exertion
|
|
ETT
|
exercise tolerance test
|
