pigment of the erythrocytesLeukocyteswhite blood cells, fight infectionNeutrophilsformed in red bone marrow, are the most common type of WBChematologista physician who specializes in diagnosing and treating abnormalities, diseases, and disorders of the blood and blood-forming tissuesAtherosclerosishardening and narrowing of the arteries caused by a buildup of cholesterol plaque on the interior walls of the arteriesAnginaa condition of episodes of severe chest pain due to inadequate blood flow to the myocardiumheart failurea chronic condition in which the heart is unable to pump out all of the blood that it receivesmyocarditisis an inflammation of the myocardium (heart muscle) that develops as a rarely seen complication of a viral infectionarrhythmiais the loss of the normal rhythm of the heartbeatAsystoleflat line, complete lack of electrical activity in the heartcardiac arrestis an event in which the heart abruptly stops beating or develops an arrhythmia that prevents it from pumping blood effectivelyBradycardiaslow heart rateTachycardiarapid heart ratepolyarteritisis a form of vasculitis involving several medium and small arteries at the same timeTemporal arteritisAlso know as giant cell arteritis is a form of vasculitis that can cause headaches, visual impairment, jaw pain, and other symptomshypoperfusiona deficiency of blood passing through an organ or body partphlebitisinflammation of a veinthrombosisthe abnormal condition of having a thrombusthrombusa blood clot attached to the interior wall of an artery or veinthrombotic occlusionis the blocking of an artery by a thrombusdeep vein thrombosisis the condition of having a thrombus attached to the interior wall of a deep veinembolismthe sudden blockage of a blood vessel by an embolusembolusis 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 bloodRaynaud's diseasea peripheral arterial occlusive disease in which intermittent attacks are triggered by cold or stressHemochromatosisa genetic disorder in which the intestines absorb too much ironLeukopeniais a decrease in the number of disease-fighting white blood cells circulating in the bloodPolycythemiais an abnormal increase in the number of red cells in the blood due to excess production of these cells by the bone marrowThrombocytopeniaa condition in which there is an abnormally small number of platelets circulating in the bloodthrombocytosisan abnormal increase in the number of platelets in the circulating bloodLeukemiaa 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 bloodAnemiaa lower than normal number of erythrocytes in the bloodaplastic anemiaabsence of all formed blood elements caused by the failure of blood cell production in the bone marrowmegaloblastic anemiaa blood disorder characterized by anemia in which the red blood cells are larger than normalpernicious anemiacaused by a lack of the protein intrinsic factor that helps the body absorb vitamin B-12 from the gastrointestinal tracthemolytic anemiacharacterized by an inadequate number of circulating red blood cells due to the premature destruction of red blood cells by the spleensickle cell anemiaa genetic disorder that causes abnormal hemoglobin, resulting in some red blood cells assuming an abnormal sickle shapeThalassemiainherited blood disorder that causes mild or severe anemia due to reduced hemoglobin and fewer red blood cells than normalorthostatic hypotensionlow blood pressure that occurs upon standing upduplex ultrasounda diagnostic procedure to image the structures of the blood vessels and the flow of blood through these vesselselectrocardiographythe noninvasive process of recording the electrical activity of the myocardiumHolter monitora portable electrocardiograph that is worn by an ambulatory patient to continuously monitor the heart rates and rhythms over a 24-48 hour periodACE inhibitorblocks the action of the enzyme that causes the blood vessels to contract resulting in hypertensionantiarrhythmica medication administered to control irregularities of the heartbeatCoumadinan anticoagulant administered to prevent blood clots from forming or growing largerAspirintaken in a very small daily dose, such as 81 mg, which is commonly known as baby aspirin, may be recommended to reduce the risk of a heart attack or stroke by reducing the ability of the blood to clot.Digitalisstrengthens the contraction of the heart muscle, slows the heart rate, and helps eliminate fluid from body tissuesthrombolyticdissolves or causes a thrombus to break uptissue plasminogen activator (tPA)a thrombolytic
