Objective  To investigate the possible association between serum level of hepatocyte growth factor( HGF) and obstructive sleep apnea hypopnea syndrome( OSAHS) with hypertension.Methods  58 cases of OSAHS without hypertension, 61 cases of OSAHS with hypertension, and 50 normal controls were enrolled. Serum level of HGF was measured by enzyme-linked immunosorbent assay( ELISA) , and the relationships between the serum HGF level and blood pressure( BP) , apnea hypopnea index( AHI) , lowest SaO2 ( LSaO2 ) were analyzed by linear correlation analysis. Results  The serum HGF level ( pg/mL) was 761. 46 ±60. 18, 970. 87 ±60. 94, and 487. 34 ±45. 52 in the OSAHS patients without hypertention, OSAHS patients with hypertention, and normal subjects, respectively. Which was significantly higher in the OSAHS
patients than the normal subjects, and highest in the OSAHS patients with hypertension( P  lt; 0. 05) . The serum HGF level was positively related to AHI( r = 0. 452, P  lt;0. 05) and negatively related to LSaO2 ( r =- 0. 328, P  lt;0. 05) in the OSAHS patients without hypertention, positively related to AHI, SBP, DBP( r =0. 670, P  lt;0. 01; r =0. 535, P  lt;0. 05; r =0. 424, P  lt;0. 05) and negatively related to LSaO2 ( r = - 0. 572,P  lt;0. 01) in the OSAHS patients with hypertension. Conclusions  SerumHGF level increases significantly in patients with OSAHS especialy in OSAHS patients with hypertension, and positively correlates with the severity of OSAHS and hypertension.
