Glossary for Pulmonary embolism

  • Anoxia: Lack of oxygen to the body's tissues.
  • Antiphospholipid syndrome: An autoimmune disorder characterized by blood clots and pregnancy losses.
  • Antithrombin III deficiency, congenital: A rare blood disorder where a congenital deficiency of antithrombin III causes excessive blood coagulation which results in blood clot formation.
  • Aortic dissection: A tear in the inner layer of the aorta (major artery in the body) which allows blood to escape into outer layers of the artery.
  • Artery conditions: Any conditions affecting arteries
  • Asthma: Repeated attacks of breathing difficulty.
  • Asthma in Adults:
  • Asthma in Children:
  • Behcet's Disease: Recurring inflammation of small blood vessels affecting various areas.
  • Bleeding and coagulation conditions:
  • Blood conditions: Conditions that affect the blood
  • Blue lips: Blueness or discoloration of the lips
  • Breathing difficulties: Various types of breathing difficulty (dyspnea).
  • COPD: Severe obstruction of bronchial air flow typically from bronchitis and/or emphysema.
  • Cardiac arrest: Stoppage of the heart, usually caused by heart attack
  • Cardiac tamponade: Symptoms caused by compression of the heart due to the accumulation of blood or fluid in the space between the heart muscle and the membrane covering the heart.
  • Cardiogenic shock: an inadequate circulation of blood due to primary failure of the ventricles of the heart to function effectively
  • Chest conditions: Any condition affecting the chest
  • Chest pain: Pain in the chest area.
  • Childbirth: Delivery of a fetus by a pregnant woman.
  • Circulatory system conditions: Medical conditions affecting the heart and the circulatory system.
  • Clotting disorders: Disorder with excessive clotting
  • Collapse: Physical or mental process shutdown
  • Coma: Prolonged unconsciousness
  • Congenital thrombotic disease due to protein C deficiency: A rare blood disorder where deficiency of protein C (anticoagulation agent) results in a predisposition for the formation of blood clots. The severity of the condition is variable. Homozygotes tend to have more severe symptoms while most heterozygotes are asymptomatic. Deficiency of protein C can be an inherited trait or may be acquired through liver disease and after surgery.
  • Congestive Heart Failure: Inadequate pumping and decline of heart function common in the elderly.
  • Cor pulmonale: Enlarged heart due to respiratory difficulty.
  • Corticobasal Degeneration: A rare progressive neurological disorder where parts of the brain deteriorate.
  • Cough: The noise produced from the sudden expulsion of air from the lungs
  • Cyanosis: Blueness or purple coloring of skin.
  • Death: The cessation of life
  • Deep vein thrombosis: Blood clot in vein, often in calf muscle vein in the leg.
  • Embolism: Blockage of an artery or blood vessel
  • Emphysema: Emphysema is a type of chronic obstructive pulmonary disease (COPD). It is defined as an abnormal, permanent enlargement of the air spaces distal to the terminal bronchioles accompanied by destruction of their walls and without obvious fibrosis.
  • Essential thrombocytosis -- same as essential thrombocythemia: A rare blood disorder where the blood contains too many platelets due to excessive megakaryocytes (platelet-producing cells). Platelets are essential for blood clotting but in essential thrombocythemia excessive platelets can cause the blood to form abnormal clots. If the platelets are defective as well then bleeding problems can occur. The severity of the condition is variable.
  • Factor V Leiden mutation: A rare genetic condition where a abnormalities in the factor V protein prevent it from being inactivated by protein C which causes the blood to clot. The normal processes which regulate the blood coagulation process is impaired. The homozygous form of the condition carries a greater risk of blood clotting than the heterozygous form.
  • Fractures: Fracture of a bone; also "broken bone".
  • Heart attack: Serious and often fatal acute heart condition
  • Heart failure: Slow failure of the heart (cardiac insufficiency).
  • Hemoptysis: A condition which is characterized by the coughing up of blood or blood stained sputum
  • Heparin-induced thrombocytopenia: A blood disorder triggered by the use of the drug called heparin which is an anticoagulant. The severity of the condition is variable.
  • Hyperventilation: Excessively rapid breathing causing blood gas imbalances
  • Idiopathic Pulmonary Fibrosis: Lung fibrosis from unknown causes.
  • Injury: Any damage inflicted in the body
  • Leg injury: Any injury that occurs to ones legs
  • Legionnaires' disease: A severe respiratory disease which is caused by the Legionella pneumophila bacteria. The condition can result in pneumonia and can be life-threatening.
  • Lung conditions: Various conditions affecting the lungs or related airways.
  • Meadows syndrome: A rare condition that affects pregnant women during the last trimester or within two months after birth. It is characterized by breathing difficult, chest pain, congestive heart failure, heart rhythm abnormalities, high blood pressure, gastrointestinal symptoms and embolisms.
  • Neuroleptic Malignant Syndrome: A severe, potentially fatal reaction to antipsychotic drugs.
  • Pericarditis: Inflammation of the membrane surrounding the heart
  • Pleurisy: Inflammation of the pleural membrane
  • Pneumocystic carinii pneumonia: An infectious disease caused by the fungus called Pneumocystitis carinii which causes pneumonia. It primarily occurs in people with a poor immune system.
  • Pneumonia: Infection of the lung by bacteria, viruses or fungus.
  • Pneumothorax: Air in the pleural spaces around the lungs.
  • Pregnancy: The condition of supporting a fetus from conception till birth.
  • Primary pulmonary hypertension: Primary pulmonary hypertension refers to high blood pressure in the arteries that carry blood to the lungs for no apparent reason. Blood pressure in other parts of the body is normal or sometimes even low.
  • Protein C deficiency: A genetic condition where a person faces an increased risk of blood clot formation. It is characterized by a deficiency of functioning protein C which is a protein needed to regulate the blood clotting process. The homozygous form of the condition carries a much higher risk of thrombosis with severe thrombosis often occurring at birth.
  • Protein S acquired deficiency: A rare disorder involving a deficiency of a blood protein called protein S. Protein S prevents blood from clotting in the veins. A deficiency of protein S can be acquired through liver disease, chemotherapy, lack of vitamin K or through the use of oral anticoagulants or L-asparaginase.
  • Protein S deficiency: A genetic condition where a person faces an increased risk of blood clot formation. It is characterized by a deficiency of functioning protein S which is a protein needed to regulate the blood clotting process. The homozygous form of the condition carries a much higher risk of thrombosis with severe thrombosis often occurring at birth.
  • Pulmonary embolus: Blood clot lodges in the arteries supplying the lungs, causing decreased blood flow and air exchange
  • Pulmonary hypertension: Pulmonary hypertension refers to high blood pressure in the blood vessels that carry blood to the lungs. Blood pressure in other parts of the body is normal or sometimes even low. The condition may be caused by such things as lung conditions (e.g. emphysema, chronic bronchitis), heart conditions (e.g. congestive heart failure, birth defects involving heart), AIDS or medications such as fenfluramine (a diet drug). Sometimes it occurs for no apparent reason and is called primary pulmonary hypertension.
  • Respiratory conditions: Any condition that affects the respiratory system
  • Respiratory failure: Failure of the respiratory system
  • Right heart failure: Heart failure of the right side of the heart
  • Shock: Severe condition from reduced blood circulation
  • Shortness of breath: The feeling of being short of breath
  • Surgical errors/complications: Any error or complication that arises from surgery
  • Thromboembolism: Lodgement of a blood clot causing blockage
  • Thrombomodulin anomalies, familial: A defect in a protein involved with anticoagulation which results in an increased risk of developing blood clots which can result in death.
  • Thrombosis: Blood clot occurring in a blood vessel
  • Wheezing: A whistling like continuous sound that is caused by the respiratory system
