    4. Classification Group 2: Left heart failure Left atrial, ventricular or valvular disease Group 3: Hypoxemia, respiratory disease COPD, Sleep disorders, alveolar hypoventilation Group 4: Chronic thrombotic, embolic dx Group 5: inflammation, mechanical obstruction, extrinsic compression sarcoid, histoiocytosis, fibrosing mediastinitis, pulmonary venous obstruction

    5. Signs and symptoms Exertional dyspnea, lethargy and fatigue Chest pain, exertional syncope, peripheral edema due to right heart failure Anorexia, abdominal pain (RUQ) due to hepatic congestion Cough, hemoptysis, hoarseness due to compression of L recurrent laryngeal nerve
