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
