| anemia | a disorder characterized by lower than normal levels of red blood cells in the blood |
| aneurysm | a localized weak spot or balloon-like enlargement of the wall of an artery |
| angina | a condition of episodes of severe chest pain due to inadequate blood flow to the myocardium |
| angioplasty | mechanically widening a narrowed or obstructed blood vessel |
| anticoagulant | medication that slows coagulation and prevents new clots from forming |
| aplastic anemia | a condition marked by the absence of all formed blood elements |
| arrhythmia | the loss of the normal rhythm of the heartbeat |
| atherectomy | surgical removal of plaque buildup from the interior lining of an artery |
| atheroma | a deposit of plaque on or within the arterial wall |
| atherosclerosis | hardening and narrowing of the arteries caused by a buildup of cholesterol plaque on the interior walls of the arteries |
| atrial fibrillation | rapid irregular twitching of the muscular wall of the atria |
| automated external defibrillator (AED) | electronic equipment that externally shocks the heart to restore a normal cardiac rhythm |
| beta-blocker | medications administered to reduce the workload of the heart by slowing the heartbeat |
| blood dyscrasia | any pathologic condition of the cellular elements of the blood |
| bradycardia | an abnormally slow resting heart rate, usually at a rate of less than 60 beats per minute |
| cardiac arrest | an event in which the heart abruptly stops beating or develops an arrhythmia that prevents it from pumping blood effectively |
| cardiac catheterization | a diagnostic procedure in which a catheter is passed into a vein or artery and then guided into the heart |
| cardiomyopathy | all diseases of the heart muscle |
| carotid endarterectomy | the surgical removal of the lining of a portion of a clogged carotid artery |
| cholesterol | a fatty substance that travels through the blood and is found in all parts of the body |
| chronic venous insufficiency | a condition in which venous circulation is inadequate due to partial vein blockage or leakage of venous valves |
| coronary artery disease | atherosclerosis of the coronary arteries that reduces the blood supply to the heart muscle |
| coronary thombosis | damage to the heart muscle caused by a thrombus blocking a coronary artery |
| defibrillation | The use of electrical shock to restore the hearts normal rhythm |
| diuretic | medications administered to increase urine secretion to rid the body of excess salt and water |
| electrocardiogram | Noninvasive process of recording the electrical activity of the myocardium |
| embolism | the sudden blockage of a blood vessel by an embolus |
| embolus | a foreign object, such as a blood clot, quantity of air or gas, or a bit of tissue or tumor that is circulating in the blood |
| endocarditis | inflammation of the inner lining of the heart |
| erythrocytes | red blood cells |
| hemoglobin | The protein in red blood cells that carries oxygen from the lungs to the rest of the body |
| hemolytic anemia | condition characterized by an inadequate number of circulating red blood cells due to their premature destruction by the spleen |
| hemostasis | to stop or control bleeding |
| leukemia | a type of cancer characterized by a progressive increase in the number of abnormal leukocytes found in blood forming tissues, other organs, and in the circulating blood |
| leukocytes | white blood cells |
| leukopenia | a decrease in the number of white blood cells circulating in the blood |
| megaloblastic anemia | a blood disorder characterized by anemia in which the red blood cells are larger than normal |
| myelodysplastic syndrome | a type of cancer in which there is insufficient production of one or more types of blood cells due to dysfunction of the bone marrow |
| myocardial infarction | the occlusion of one or more coronary arteries caused by plaque buildup (heart attack) |
| orthostatic hypotension | low blood pressure that occurs upon standing up |
| pericardium | Double-layered membrane surrounding the heart. |
| pernicious anemia | anemia caused by a lack of a protein that helps the body absorb vitamin B12 from the gastrointestinal tract |
| phlebitis | inflammation of a vein |
| Raynaud's Disease | a peripheral arterial occlusive disease in which intermittent attacks are triggered by cold or stress |
| sepsis | Infection that results from bacteria or other infectious organisms entering the bloodstream |
