The goal of this clinical trial is to learn the effectiveness of remote home-based exercise rehabilitation using mobile Internet technology for patients with pulmonary hypertension，especically providing early and mid-term results of its effectiveness. The main questions it aims to answer are:

Dose tele-rehabilitation training improves prognostic function and quality of life in patients with pulmonary hypertension？ Researchers will compare tele-rehabilitation training group to a control group (receive health propaganda and education, and then follow their daily routine after discharge from the hospital) to see if tele-rehabilitation training works to improve prognosis.

Participants will:

During their stay in the hospital, the patients of tele-rehabilitation training group were accompanied by a rehabilitation trainer and a psychotherapist for a complete cycle of (7 days ± 3 days 1 week/times) standardized training. The scheme of rehabilitation is impedance training. A specialized professional team including cardiologists, rehabilitation trainers, psychotherapists and radiologists were involved. After discharge from the hospital, patients in the rehabilitation group underwent 3-5 weekly daily training sessions and intensive supervision and management by the online community at least once a week.

Visit the clinic at the 3rd month of the study. Extended follow-up up to 6 months may be considered if patients are cooperative and could complete the training program in the first 3 months.
