|severe disease variably characterized by anemia, weight loss, exercise intolerance, tachypnea at rest, severe or persistent coughing, dyspnea, hemoptysis, syncope, and ascites. Severely abnormal radiographs may show right ventricular hypertrophy, enlargement of the main pulmonary artery, and diffuse pulmonary densities. Laboratory results indicate marked anemia, thrombocytopenia, and proteinuria. Electrocardiographic evidence of right ventricular hypertrophy is often present.

Radiographs appear abnormal: right ventricular hypertrophy, enlargement of the main pulmonary artery, and diffuse pulmonary densities. ECG often shows right ventricular hypertrophy. Aneamia, thrombocytopenia, and proteinuria are seen.</center>
