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

-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
