Ven/o Vein
ACE Inhibitor (Angiotensin-converting Enzyme) Blocks the action of the enzyme that causes the blood vessels to contract, resulting in hypertension
Anemia Lower-than-normal number of erythrocytes
Aneurysm Localized weak spot or balloon-like enlargement of the wall of an artery
Angina (Angina Pectoris) Severe episodes of chest pain occur due to an inadequate blood flow to the myocardium
Angioplasty Technique of mechanically widening a narrowed or obstructed blood vessel
Anticoagulant Slows coagulation and prevents new clots from forming
Aplastic Anemia Absence of all formed blood elements caused by the failure of blood cell production in the bone marrow
Arrhythmia Loss of the normal rhythm of the heartbeat
Atherectomy Surgical removal of plaque buildup from the interior of an artery
Atheroma Characteristic of atherosclerosis, is 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 (A-fib) Occurs when the normal rhythmic contractions of the atria are replaced by rapid, irregular twitching of the muscular heart wall
Automated External Defibrillator (AED) Designed for nonprofessionals. It automatically samples the electrical rhythms of the heart and shocks if necessary
Beta-Blocker Reduces the workload of the heart by slowing the rate of the heart
Blood Dyscrasia Any pathologic condition of the cellular elements of the blood
Bradycardia Abnormally slow resting heart rate
Cardiac Arrest Event in which the heart abruptly stops beating or develops an arrhythmia that prevents it from pumping blood effectively
Cardiac Catheterization Diagnostic procedure in which a catheter is passed into a vein or artery and then guided into the heart
Cardiomyopathy Describes all disease of the heart muscle
Carotid Endarterectomy Surgical removal of the lining of a portion of a clogged carotid artery leading to the brain
Cholesterol Fatty substance that travels through the blood and is found in all parts of the body
Chronic Venous Insufficiency (Venous Insufficiency) Condition in which venous circulation is inadequate due to partial vein blockage or to the leakage of venous valves
Coronary Thrombosis Damage to the heart muscle caused by a thrombus blocking a coronary artery
Defibrillation (Cardioversion) Use of electrical shock to restore the heart's normal rhythm
Diuretic Stimulates the kidneys to increase the secretion of urine to rid the body of excess sodium and water
Electrocardiogram Record of the electrical activity of the myocardium
Embolism Sudden blockage of a blood vessel by an embolus
Embolus A foreign object, such as a blood clot, a 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 (RBC's) Mature red blood cells produced by the red bone marrow
Hemoglobin Oxygen-carrying blood protein pigment of the erythrocytes
Hemolytic Anemia Inadequate number of circulating red blood cells due to the premature destruction of red blood cells by the spleen
Hemostasis Means to stop or control bleeding
Ischemic Heart Disease Group of cardiac disabilities resulting from an insufficient supply of oxygenated blood to the heart
Leukemia Type of cancer characterized by a progressive increase in the number of abnormal leukocytes
Leukocytes (WBC's) Blood cells involved in defending the body against infective organisms and foreign substances
Leukopenia Decrease in the number of disease-fighting white blood cells circulating in the blood
Megaloblastic Anemia Anemia in which the red blood cells are larger than normal
Myelodysplastic Syndrome Group of bone marrow disorders that are characterized by the insufficient production of one or more types of blood cells due to dysfunction of the bone marrow
Myocardial Infarction (Heart Attack) Occlusion of one or more coronary arteries caused by plaque buildup
Orthostatic Hypotension (Postural hypotension) Low blood pressure that occurs upon standing up
Pericardium (Pericardial sac) Double-walled membranous sac that encloses the heart
Pernicious Anemia Caused by a lack of the protein Intrinsic Factor that helps the body absorb vitamin B12 from the gastrointestinal tract
Phlebitis Inflammation of a vein
Raynaud's Disease Peripheral arterial occlusive disease in which intermittent attacks are triggered by cold or stress
Septicemia Associated with severe infections caused by the presence of bacteria in the blood
Sickle Cell Anemia Genetic disorder that causes abnormal hemoglobin, resulting in some red blood cells assuming an abnormal sickle shape
Tachycardia Abnormally rapid resting heart rate
Temporal Arteritis (Giant cell arteritis) Form of vasculitis that can cause headaches, visual impairment, jaw pain, and other symptoms
Thallium Stress test Evaluate how well blood flows through the coronary arteries of the heart muscle during exercise by injection a small amount of thallium into the bloodstream
Thrombocytopenia Condition in which there is an abnormally small number of platelets circulating in the blood
Thrombolytic (Clot-busting drug) Dissolves or causes a thrombus to break up
Thrombosis Abnormal conditions of having a thrombus
Thrombotic Occlusion Blocking of an artery by a thrombus
Thrombus Blood clot attached to the interior wall of an artery or vein
Transfusion reaction Serious and potentially fatal complication of a blood transfusion in which a severe immune response occurs because the patient's blood and the donated blood do not match
Valvulitis Inflammation of a heart valve
Varicose Veins Abnormally swollen veins that usually occur in the superficial veins of the legs
Ventricular Fibrillation (V-fib) Rapid, irregular, and useless contractions of the ventricles which can cause sudden cardiac death
Ventricular Tachycardia (V-tach) Very rapid heartbeat that begins within the ventricles and the heart is beating so rapidly it is unable to adequately pump blood through the body
Capillaries One cell in thickness and the smallest blood vessels in the body
Pulmonary Arteries Carry deoxygenated blood from the right ventricles to the lungs
Plaque Fatty deposit that can be found on an artery wall
Systolic Blood Pressure Highest pressure against the artery walls when the ventricles contract in the heart
Holter Monitor Portable electrocardiograph that is worn by an ambulatory patient to continuously monitor heart rate and rhythm over a 24 - 48 hour period
Heart failure chronic condition in which the heart is unable to pump out all of the blood is receives
Cardiopulmonary Resuscitation Consists of artificial respiration and manual external cardiac compressions
Myocarditis Inflammation of the heart muscle
