PAH: pulmonary arterial hypertension; HIV: human immunodeficiency virus; PVOD: pulmonary veno-occlusive disease; PCH: pulmonary capillary haemangiomatosis; PH: pulmonary hypertension.
* Patients with heritable PAH or PAH associated with drugs and toxins might be acute responders.
¶ Left ventricular ejection fraction for heart failure with reduced ejection fraction: ≤40%; for heart failure with mildly reduced ejection fraction: 41 to 49%.
Δ Other causes of pulmonary artery obstructions include: sarcomas (high or intermediate grade or angiosarcoma), other malignant tumours (eg, renal carcinoma, uterine carcinoma, germ-cell tumours of the testis), non-malignant tumours (eg, uterine leiomyoma), arteritis without connective tissue disease, congenital pulmonary arterial stenoses, and hydatidosis.
◊ Including inherited and acquired chronic haemolytic anaemia and chronic myeloproliferative disorders.
§ Including sarcoidosis, pulmonary Langerhans's cell histiocytosis, and neurofibromatosis type 1.
¥ Including glycogen storage diseases and Gaucher disease.Do you want to add Medilib to your home screen?
