The Correlation Between Obstructive Sleep Apnea-Hypopnea Syndrome and Pulmonary Hypertension

Objective To evaluate obstructive sleep apnea hypopnea syndrom (OSAHS) on pulmonary hypertension (PH)and right heart function.Methods Seventy-two patients with OSAHS and 23 snoring patients were determined by polysomnography and echocardiographic to evaluate heart structure,hemodynamic parameters measurement and pulmonary hypertension PH.Results Seventy-two patients with OSAHS in the incidence of PH,right heart structure and hemodynamic changes were significantly higher than that of 23 snoring patients (P <0.05 or P <0.01),OSAHS patients with PH, right heart structure and hemodynamic changed good correlation with OSAHS severity.Conclusions The incidence of OSAHS patients with PH was higher,patients with OSAHS combined PH at the same time whose right heart structure changed was obvious.Severity of PH and right heart structure was changed with the severity of OSAHS.
