The Cardiovascular System (Lab Tests & Clinical Procedures)

Angiography (x-ray) X-ray imaging of blood vessels after injection of contrast material.
BNP test (laboratory test) Measurement of BNP (brain natriuetic peptide) in blood.
Cardiac biomarkers (laboratory test) Chemicals are measured in the blood as evidence of a heart attack.
Cardiac catherization (clinical procedure) Thin, flexible is guided into the heart via a vein or an artery.
Cardiac MRI Images of the heart are produced using radiowave energy in a magnetic field.
Catheter ablation (clinical procedures-treatment) Brief delivery of radiofrequency or cryosurgery to destroy areas of heart tissue that may be causing arrhythmias.
Coronary artery bypass grafting (CABG) (clinical procedures-treatment) Arteries and veins are anastomodes to coronary arteries to detour around blockages.
Computed tomography angiography (CTA) (x-ray) Three-dimensional x-ray images of the heart and coronary arteries using computed tomography (CT) (64-slice CT scanner).
Defibrillation (clinical procedures-treatment) Brief discharges of electricity are applied across the chest to stop dysrhythmias (ventricular fibrillation).
Digital subtraction angiography (DSA) (x-ray) Video equipment and a computer produce x-ray images of blood vessels.
Doppler ultrasound studies (ultrasound) Sound waves measure blood flow within blood vessels.
Echocardiography (ECHO) (ultrasound) Echoes generated by high-frequency sound waves produce images of the heart.
Electrocardiography (ECG) Recording of electricity flowing through the heart.
Electron beam computed tomography (EBCT or EBT) (x-ray) Electron beams and CT identify calcium deposits in and around coronary arteries in diagnose early CAD.
Endarterectomy (clinical procedures-treatment) Surgical removal of plaque from the inner layer of an artery.
Extracorporeal circulation (clinical procedures-treatment) Heart-lung machine divers blood from the heart and lungs while the heart is repaired.
Heart transplantation (clinical procedureS-treatment) A donor heart is transferred to a recipient.
Holter monitoring An ECG device is worn during a 24-hour period to detect cardiac arrhythmias.
Lipid tests (lipid profile) (laboratory test) Measurement of cholesterol and triglycerides (fats) in a blood sample.
Lipoprotein electrophoresis (laboratory test) Lipoproteins (combinations of fat and protein) are physically separated and measured in a blood sample.
Percutaneous coronary intervention (PCI) (clinical procedures-treatment) Balloon-tipped catheter is inserted into a coronary artery to open the artery; stents are put in place.
Positron emission tomography (PET) scan (nuclear cardiology) Images show blood flow and myocardial function following uptake of radioactive glucose.
Stress test (clinical procedure) Exercise tolerance test (ETT) determines the heart's response to physical exertion (stress).
Technetium Tc 99m sestamibi scan (nuclear cardiology) Technetium Tc 99m sestamibi injected intravenously is taken up in cardiac tissue, where it is detected by scanning.
Thallium 201 scan (nuclear cardiology) Concentration of radioactive thallium is measured to give information about blood supply to the heart muscle.
Thrombolytic therapy (clinical procedures-treatment) Drugs to dissolve clots are injected into the bloodatream of patients with coronary thrombosis.
