Signs and symptoms
Because symptoms may develop very gradually, patients may delay seeing a physician for years. Common symptoms are shortness of breath, fatigue, non-productive cough, angina pectoris, fainting or syncope, peripheral edema (swelling of the limbs which commonly manifests around the ankles and feet), and rarely hemoptysis (coughing up blood). Pulmonary arterial hypertension (PAH) typically does not present with orthopnea or paroxysmal nocturnal dyspnea, while pulmonary venous hypertension typically does.
In order to establish the cause, the physician will conduct a thorough medical history followed by a physical examination. A detailed family history is established to determine whether the disease might be hereditaryfamilial. A history of exposure to drugs such as cocaine, methamphetamine, alcohol leading to cirrhosis, and smoking leading to emphysema are considered significant. A physical examination is performed to look for typical signs of pulmonary hypertension, including a loud P2 (pulmonic valve closure sound), (para)sternal heave, jugular venous distension, pedal edema, ascites, hepatojugular reflux, clubbing etc. Evidence of tricuspid insufficiency is also sought and, if present, is consistent with the presence of pulmonary hypertension.
