Pulmonary Venous Hypertension
Monday, March 14, 2011
What is pulmonary venous hypertension, it is term of incrieasing in blood pressure in the pulmonary artery pulmonary vein, or pulmonary capillaries, together known as the lung vasculature, leading to shortness of breath, dizziness, fainting, and other symptoms,
Due to the fact indicators may develop very slowly, patients may delay seeing a physician for a long time. Common symptoms are shortness of breath, fatigue, non-productive ugg, angina pectoris, fainting or syncope, peripheral edema (swelling across the ankles and feet), and seldom hemoptysis (coughing up blood).
Pulmonary venous hypertension usually presents having shortness of breath while lying flat or sleeping (orthopnea or paroxysmal nocturnal dyspnea), while pulmonary arterial hypertension (PAH) typically does not.
A detailed genealogy is organized to determine whether the disease might be familial. A record of exposure to drugs including cocaine, methamphetamine, alcohol resulting cirrhosis, and smoking cigarettes leading to emphysema are usually considered considerable. A physical examination is definitely performed to discover typical indicators of pulmonary hypertension, as well as a loud S2 (pulmonic valve drawing a line under sound), (para)sternal heave, jugular venous distension, pedal edema, ascites, hepatojugular reflux, clubbing etc. Evidence of tricuspid insufficiency is also sought and also, in the event present, is definitely consistent with the profile of pulmonary hypertension.
[edit]Diagnosis
Because pulmonary hypertension can be of five major forms, a series of lab tests must be done to distinguish pulmonary arterial hypertension from venous, hypoxic, thromboembolic, or miscellaneous varieties.
A NEW physical examination is done to look for typical signs of pulmonary hypertension. These include altered heart sounds, say for example widely split S2 or second heart sound, a loud P2 or pulmonic valve closure sound (part of the 2nd heart sound), (para)sternal heave, possible S3 or third heart sound, and pulmonary regurgitation. Other signs include an elevated jugular venous pressure, peripheral edema (swelling of the ankles and feet), ascites (abdominal swelling due to the accumulation of fluid), hepatojugular reflux, and clubbing.
Further procedures are required to confirm the presence of pulmonary hypertension and exclude other possible diagnoses. These generally include pulmonary function tests; blood tests to exclude HIV, autoimmune diseases, and liver disease; electrocardiography (ECG); arterial blood gas measurements; X-rays of the chest (followed by high-resolution CT scanning if interstitial lung disease is suspected); and ventilation-perfusion or V/Q scanning to exclude.
