Chabner Ch11- Tests
Cardiovascular System - Laboratory Tests & Clinical Procedures
| Question | Answer |
|---|---|
| BNP | measurement of BNP (brain natriuretic peptide) in blood. |
| cardiac biomarkers | chemicals are measured in the blood as evidence of a heart attack. |
| lipid tests (lipid profile) | measurement of cholesterol and triglycerides (fats) in a blood sample. |
| 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. |
| computed tomogaphy angiography (CTA) | three-dimensional x-ray images of the heart and coronary arteries using computed tomography (CT) (64-slice CT scanner). |
| 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 blood flow within blood vessels. |
| 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 glucose. |
| technetium Tc 99m sestamibi scan | technetium Tc 99m sestamibi injected intravenously 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. |
| electrocardiography (ECG) | recording of electricity flowing through the heart. |
| Holten monitoring | an ECG 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 delivery of radiofrequency or cryosurgery to destroy areas of heart tissue that may be causing arrhythmias. |
| coronary artery bypass grafting (CABG) | arteries and veins are anastomosed to coronary arteries to detour around blockages. |
| defibrillation | brief discharges of electricity are applied across the chest to stop dysrhythmias (ventricular fibrillation). |
| extracorporeal circulation | heart-lung machine diverts blood from the heart and lungs while the heart is repaired. |
| heart transplantaion | a donor heart is transferred to a recipient. |
| percutaneous coronary intervention (PCI) | balloon-tipped catheter is inserted into a coronary artery to open the artery. stents are put in place. |
| throbolytic therapy | drugs to dissolve clots are injected into the bloodstream of patients with coronary thrombosis. |
