目的探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)与高血压的关系。方法对确诊患者行多导睡眠图(PSG)监测,观察呼吸暂停低通气指数(AHI)、夜间最低血氧饱和度(SaO2)、减氧次数、睡前、醒后血压等指标进行分析。结果 OSAHS患者醒后血压较睡前血压增高(P<0.05)并与SaO2成负相关(P<0.05),SaO2与AHI呈负相关(P<0.05),体质量指数与SaO2成负相关(P<0.05)。结论 OSAHS患者肥胖及反复睡眠呼吸暂停与高血压具有相关性,早期对OSAHS进行评估、干预,可为预防和治疗心脑血管疾病提供依据。
Objective To investigate the relationship between obstructive sleep apnea-hypopnea syndrome (OSAHS) and hypertension. Methods The polysomnography (PSG) monitoring was performed on the confirmed patients. The AHI, night oxygen saturation (SaO2), the number of hypoxia, the bedtime and waking blood pressure were analyzed. Results The blood pressure of OSAHS patients was significantly higher than that before bedtime (P <0.05), negatively correlated with SaO2 (P <0.05), SaO2 was negatively correlated with AHI (P <0.05), and body mass index was negatively correlated with SaO2 <0.05). Conclusion OSAHS patients with obesity and recurrent sleep apnea and hypertension are related to the early assessment of OSAHS intervention, may provide a basis for the prevention and treatment of cardiovascular and cerebrovascular diseases.
