Clinical Information

• A pulmonary embolism is a sudden blockage in a lung artery. The cause is usually a blood clot in the leg called a deep vein thrombosis that breaks loose and travels through the bloodstream to the lung. Pulmonary embolism is a serious condition that can cause
  • permanent damage to the affected lung
  • low oxygen levels in your blood
  • damage to other organs in your body from not getting enough oxygen
  if a clot is large, or if there are many clots, pulmonary embolism can cause death. Half the people who have pulmonary embolism have no symptoms. If you do have symptoms, they can include shortness of breath, chest pain or coughing up blood. Symptoms of a blood clot include warmth, swelling, pain, tenderness and redness of the leg. The goal of treatment is to break up clots and help keep other clots from forming.
• Blocking of the pulmonary artery or one of its branches by an embolus.
• The closure of the pulmonary artery or one of its branches by an embolus, sometimes associated with infarction of the lung.
• The obstruction of the pulmonary artery or one of its branches by an embolus, sometimes associated with infarction of the lung.

Approximate Synonyms

• Right heart failure due to pulmonary hypertension
• Secondary pulmonary hypertension
• Secondary pulmonary hypertension (htn)

Clinical Information

• A disorder characterized by an increase in pressure within the pulmonary circulation due to lung or heart disorder.
• Increased pressure with the pulmonary circulation, usually secondary to cardiac or pulmonary disease.
• Increased pressure within the pulmonary circulation due to lung or heart disorder.
• Increased vascular resistance in the pulmonary circulation, usually secondary to heart diseases or lung diseases.
• Pulmonary hypertension is high blood pressure in the arteries to your lungs. It is a serious condition for which there are treatments but no cure. If you have it, the blood vessels that carry oxygen-poor blood from your heart to your lungs become hard and narrow. Your heart has to work harder to pump the blood through. Over time, your heart weakens and cannot do its job and you can develop heart failure. There are two main kinds of pulmonary hypertension. One runs in families or appears for no known reason. The other kind is related to another condition, usually heart or lung disease. Treating pulmonary hypertension involves treating the heart or lung disease, medicines, oxygen and sometimes lung transplantation.

This complex is characterized by progressive pulmonary hypertension; hypertrophy of the right ventricle; cyanosis; and erythrocytosis.
• A syndrome characterized by the reversal of a septal defect-associated left-to-right shunt due to the resulting secondary pulmonary hypertension. The presence of the pulmonary hypertension causes increased pressure in the right heart chambers resulting in the reversal of the shunt into a right-to-left shunt. Signs and symptoms include cyanosis, pulmonary hypertension, heart failure, and high red blood cell count.

Clinical Information

• Heart disease due to pulmonary hypertension secondary to disease of the lungs, or its blood vessels, with hypertrophy of the right ventricle.
• Heart disease which occurs as a result of a primary pulmonary disease. Cor pulmonale most often manifests as right ventricular hypertrophy; it can also lead to right ventricular failure.
• Hypertrophy and dilation of the right ventricle of the heart that is caused by pulmonary hypertension. This condition is often associated with pulmonary parenchymal or vascular diseases, such as chronic obstructive pulmonary disease and pulmonary embolism.
