English summary: Pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension in Finland

Background

Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are rare diseases with dismal prognosis. Treatment options for these diseases have improved over the past ten years and are totally different from the management of pulmonary hypertension due to other reasons, of which heart and lung diseases are the most common. Therefore, it is essential to distinguish between the different causes of pulmonary hypertension and this should be done according to current international guidelines.
