PURPOSE: Sleep apnea hypopnea syndrome (SAHS) is associated with cardiovascular complication including pulmonary circulation and systemic circulation. This study was to evaluate the impact of SAHS on pulmonary hypertension (PH) and right heart function.

METHODS: There were 72 patients with SAHS and 23 snoring subjects who were qualified to inclusion for study after determined by polysomnography (PSG) and echocardiograph to evaluate heart structure, hemodynamic parameters and pulmonary hypertension.

RESULTS: The 72 patients with SAHS detected by echocardiograph in which there were 28 patients (38.89%) with PH (PASP≥40mmHg). There were only 4 subjects (17.39%) with PH in the 23 snoring subjects. The incidence of PH in patients with SAHS was significantly higher than that of snoring subjects (P < 0.05). The right cardiac structure changed in PH group was significantly higher than that in non PH group (P < 0.05 or P < 0.01). The level of PH and right heart structure and hemodynamic changed in SAHS patients with PH were correlated well with severity of SAHS

CONCLUSIONS: The incidence of SAHS patients with PH was higher and severity of PH and impairment of right heart structure in SAHS was associated with the severity of OSAHS.

CLINICAL IMPLICATIONS: The findings remind us to pay attention to detect PH in SAHS.
