Cardiovascular System
| Term | Definition |
|---|---|
| heart | propels blood for the transport of respiratory gases, nutrients, wastes, and immune substances in the body |
| endocardium | inner lining of the heart |
| myocardium | heart muscle |
| epicardium | top layer of the heart |
| pericardium | sac holding the heart |
| Right and Left atria | receive blood |
| ventricles | pump blood from the heart |
| valves | prevent back flow of blood |
| arteries | carry blood away from the heart |
| capillaries | join the arterial system with the venous system |
| veins | carry blood to the heart |
| aneurysm/o | aneurysm |
| angi/o, vascul/o | vessel |
| aort/o | aorta |
| arteri/o | artery |
| arteriol/o | arteriole |
| atri/o | atrium |
| ather/o | fatty plaque |
| cardi/o, coron/o | heart |
| electr/o | electricity |
| embol/o | embolus |
| hemangi/o | blood vessel |
| my/o | muscle |
| phleb/o, ven/o | vein |
| scler/o | hardening |
| sept/o | septum |
| sphygm/o | pulse |
| sten/o | narrowing, stricture |
| thromb/o | blood clot |
| valv/o, valvul/o | valve |
| ventricul/o | ventricle |
| -cardia | heart condition |
| arteriosclerosis | degenerative disease of the arteries caused by buildup of fatty plaque (atheroma) |
| coronary artery disease (CAD) | any disorder of the coronary arteries that affects their ability to deliver blood to the myocardium |
| aneurysm | local dilation of an artery which may cause thrombus formation, hemorrhage from rupture, or ischemia |
| varicose veins | twisted, enlarged veins caused by blood pooling in the veins, especially in the legs |
| coronary artery bypass graft (CABG) | grafted vessel anastomosed around a locked segment of the coronary artery (indicated for CAD) |
| percutaneous transluminal coronary angioplasty (PTCA) | Stent placed at site of plaque via balloon catheter |
| carotid artery ultrasound | ultrasound probe passed over the carotid to identify blockages in the artery |
| endarterectomy | removes atheromatous plaque from the inner lining of the carotid artery |
| electrocardiography (ECG/EKG) | records electrical impulses of the heart using electrodes places strategically on the body |
| Holter monitor | ECG that records electrical activity for 24-48 hours |
| Stress test | ECG that evaluates heart function under stressful conditions |
| Implantable cardioverter-defibrilator | implanted in patients at risk for arrhythmias. monitors heart rate and corrects tachycardia, bradycardia, and delivers electricity to restart the heart if it stops |
| cardiac catheterization | catheter guided into the heart for diagnostic purposes |
| coronary angiography | cardiac cath under fluoroscopic guidance |
| ACE inhibitors | lower blood pressure |
| ARBs | lower blood pressure |
| antiarrhythmics | prevent, alleviate, or correct arrhythmias |
| anticoagulants | inhibit coagulation to prevent formation of clots |
| beta blockers | block the affect of adrenaline |
| calcium channel blockers | block movement of calcium |
| diuretics | reduce fluid buildup |
| nitrates | dilate blood vessels of the heart |
| statins | lower cholesterol |
