ABSTRACT
Objective To explore the clinical characteristic,level of plasma renin angiotensin (PRA),plas-ma angiotensin Ⅱ(Ang Ⅱ)and plasma aldosterone(Aldo)in the sleep apnea hypopnea syndrome (SAHS)patients, and to investigate the association between SAHS and hypertension.Methods The patients were selected for the study who were monitored with polysomnography.They were divided into SAHS group and non-SAHS group according to apea-hypopnea index(AHI),and there were 180 patients in the SAHS group,175 patients in the non-SAHS group. The systolic blood pressure(SBP),diastolic blood pressure(DBP)and the level of PRA,plasma Ang II and plasma Aldo were compared by variance analysis.Results The gender composition was different between the two groups,and had statistically significant difference(χ2 =16.30,P <0.01).The data of age,body mass index,neck circumference, waistline,DBP,SBP in SAHS group were significantly higher than those in non-SAHS group,and the differences were statistically significant(t =6.84,8.19,9.84,6.63,7.08,5.45,all P <0.01 ).The prevalence of hypertension in SAHS group was 46.58%,which was higher than 18.20% in non-SAHS group,and the difference had statistically significant(χ2 =46.71,P <0.01).The AHI had positive correlation with SBP,DBP,and they had statistically signifi-cant differences (rs =0.162,0.228,all P <0.01).The levels of PRA and plasma Ang Ⅱ were lower in SAHS group than those in non-SAHS group,while the level of plasma Aldo was higher in SAHS group than that in non-SAHS group,and had statistically significant differences(F =15.41,14.21,17.67,all P <0.01).In the SAHS group,the levels of PRA and plasma Ang Ⅱ were lower in hypertension group than those in non-hypertension group,while the level of plasma Aldo was higher in hypertension group than that in non-hypertension group,and had statistically signif-icant differences (F =15.41,14.21,17.67,all P <0.01).Also,the levels of PRA and plasma Ang Ⅱ were lower in SAHS group with hypertension than those in non-SAHS group with hypertension,while the level of plasma Aldo was higher in SAHS group with hypertension than that in non-SAHS group with hypertension,and the differences were sta-tistically significant(F =15.41,14.21,17.67,all P <0.01).Conclusion The occurrence of SAHS is correlated with the gender composition,age,body mass index,neck circumference,waistline,DBP and SBP.In SAHS complica-tions in each system,the highest incidence is hypertension.And the AHI has positive correlation with SBP,DBP,and the difference is significant.In the SAHS group,if the AHI is higher,the risk of hypertension is greater.In the SAHS patients with hypertension,the level of plasma Aldo is significantly elevated,while the levels of PRA and plasma AngⅡ are decreased significantly.
ABSTRACT
father′s hypertension. Conclusion In addition to mother′s menses irregularity and father′s premature balding, father′s hypertension may also be an independent phenotype in families of women with PCOS.
