Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Over half of chronic obstructive pulmonary disease (COPD) patients develop pulmonary hypertension. The current therapy focuses only on the basic disease and there are a lot of controversies about the use of PAH target therapy in group 3 pulmonary hypertension. Our study is to explore whether sildenafil, a pulmonary arterial hypertension (PAH) target drug, could be efficient and safe in improving symptoms and survival of severe pulmonary hypertension caused by COPD.
