What is pulmonary vascular disease? The definition of pulmonary vascular disease is easy; it is any condition that affects the blood vessels is the route between the lungs and the heart. Blood will travel from the heart to the lungs, and then back to the heart. This is a very important process because the lungs continually load the blood with oxygen, and exhales carbon dioxide. So if there is a disease present with this vasculature, it goes without saying that this is a serious problem for the patient.

Pulmonary Vascular Disease Practice Questions:

1. Deep Vein Thrombosis (D.V.T.): Blood clot forming in the deep veins, usually the legs

2. How can you detect a Pulmonary Embolism in patients?: Pulmonary embolism is detected by chest x-ray, pulmonary angiography, and radio scanning of the lung fields

3. IPAH is a rare disease but it normally affects what group of people?: Young Adults

4. Name some pharmacologic choices for prophylaxis of venous thromboembolism?: Low-dose subcutaneous heparin, Warfarin, low-molecular-weight heparin (enoxaparin) and dextran. These would be considered anticoagulation drug therapy.

5. Name the 5 categories Pulmonary Hypertension is classified as according to the Fourth World Symposium on Pulmonary Hypertension in 2008?: 1. Pulmonary Artery Hypertension (PAH), 2. Pulmonary Hypertension owing to left heart disease, 3. Pulmonary hypertension owing to lung diseases or hypoxia or both, 4. Chronic thromboembolic pulmonary hypertension, 5. Pulmonary hypertension with unclear multifactorial mechanism.

6. Pulmonary Embolism (P.E.): Blockage of a pulmonary artery by foreign matter. The obstruction may be fat, air, tumor tissue, or a thrombosis that usually arises from a peripheral vein (most frequently arising from the deep veins of the legs)

7. Pulmonary Hypertension: Condition characterized by abnormally high pulmonary artery pressures. (i.e., mean pulmonary artery pressure greater than 25mm Hg at rest)

8. What do hospitalized patients who are immobile need for the prevention of thromboembolism?: Prophylaxis

9. What is Pulmonary Hypertension called in patients with no underlying etiology that can be identified?: Idiopathic Pulmonary Artery Hypertension (I.P.A.H.)

10. Why is early recognition and treatment of DVT and PE essential?: Because 1/3rd of deaths occur within 1 hour of symptom onset. Mortality rates in patients with PE undiagnosed is 30%; if venous thrombosis is recognized and managed, the mortality rate is less than 8%
