Lab Tests Flashcards
lipid tests
measurement of cholesterol and fats in a blood sample
BNP
measurement of brain natriuretic peptide in blood
lipoprotein electrophoresis
lipoproteins (combinations of fat and protein) are physically separated in a blood sample
serum enzyme tests
chemicals measured in the blood as evidence of a heart attack
angiography
x ray imaging of blood vessels after injection of contrast material
computerized tomography angiography (CTA)
3D x ray images of the heart and coronary arteries using computed tomography (CT)
digital subtraction angiography (DSA)
video equipment and a computer produce x ray images of blood vessels
electron beam computed tomography (EBCT or EBT)
electron beams and CT identify calcium deposits in and around coronary arteries to diagnose early CAD
Doppler ultrasound studies
sound waves measure movement of blood flow
echocardiography (ECHO)
echoes generated by high frequency sound waves produce images of the heart
positron emission tomography (PET) scan
images show blood flow and myocardial function following uptake of radioactive substances
technetium Tc 99n sestamibi scan
technetium Tc 99m sestamibi injected intravenously is taken up in cardiac tissue where it’s detected by scanning
thallium 201 scan
concentration of a radio active substance is measured in the myocardium
cardiac MRI
images of the heart are produced with magnetic waves
cardiac catheterization
a thin, flexible tube is guided into the heart via a vein or an artery
electrocardiography
recording of electricity flowing through the heart
holter monitoring
an ECG device is worn during a 24 hour period to detect cardiac arrhythmias
cardioversion (defibrillation)
very brief discharges of electricity applied across the chest to stop arrhythmias
coronary artery bypass grafting (CABG)
arteries and veins are anastomosed to coronary arteries to detour around blockages
endarterectomy
surgical removal of plaque from the inner layer of an artery
extracorporeal circulation
a heart lung machine diverts blood from the heart and lungs while the heart is repaired
heart transplantation
a donor heart is transferred to a recipient
percutaneous coronary intervention (PCI)
a balloon tipped catheter is inserted into a coronary artery to open the artery; stents are put into place
thrombolyctic therapy
drugs to dissolve clots are injected into the bloodstream of patients with coronary thrombosis
