BNP test
measurement of brain natriuretic peptide in the blood. elevated in patients with heart failure.
cardiac biomarkers
chemicals measured in the blood as evidence of a heart attack. damaged heart muscle releases chemicals into the bloodstream. the substances tested for are troponin-I and troponin-T
lipid tests (lipid profile)
measurement of cholesterol and triglycerides in a blood sample
saturated fats
animal origin, such as milk, butter, and meats; increase blood cholesterol
polyunsaturated fats
vegetable origin, such as corn and safflower oil; decrease blood cholesterol
lipoprotein electrophoresis
lipoproteins (combinations of fat and protein) are physically separated and measured in a blood sample
angiography
x ray imaging of blood vessels after injection of contrast material
CTA
computed tomography angiography; 3-D x-ray images of the heart and coronary arteries using computed tomography
DSA
digital subtraction angiography; electron beams and CT identify calcium deposits in and around coronary arteries to diagnose early CAD
doppler ultrasound studies
sound waves measure blood flow within blood vessels
ECHO
echocardiography; echoes generated by high-frequency sound waves produce images of the heart
TEE
transesophageal echocardiography; trasducer is placed in the esophagus and provides ultrasound and doppler information
PET scan
positron emission tomography scan; images show blood flow and myocaridal function following uptake of radioactive glucose
technetium Tc 99m sestamibi scan
Technectium Tc 99m sestamibi injected iintravenously is taken up in cardiac tissue, where it is detected by scanning
thallium 201 scan
concentration of radioactive thallium is measured to give information about blood supply to the heart muscle
cardiac MRI
images of the heart are produced using radiowave energy in a magnetic field
cardiac catheterization
thin, flexible tube is guided into the heart via a vein or an artery
ECG/EKG
electrocardiography; recording of electricity flowing through the heart
Holter monitoring
an ECG device is worn during a 24 hour period to detect cardiac arrhythmias
stress test
exercise tolerance test (ETT) determines the heart's response to physical exertion (stress)
catheter ablation
brief dellivery of radiofrequency or cryosurgery to destroy areas of heart tissue that may be causing arrhythmias
CABG
coronary artery bypass grafting; arteries and veins are anastomosed to coronary arteries to detour around blockages
defibrillation
brief discharge of electricity are applied across the chest to stop dysrhythmias (v-fib)
endarterectomy
surgical removal of plaque from the inner layer of an artery
extracorporeal circulation
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
PCI
percutaneous coronary intervention
thrombolytic therapy
drugs to dissolve clots are injected into the bloodstream of patients with coronary thrombosis
AAA
