141例中年期阻塞性睡眠呼吸暂停低通气综合征合并高血压患者的睡眠监测分析

目的分析中年期阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea-hypopnea syndrome, OSAHS) 合并高血压患者的多导睡眠监测特点。方法对中年期OSAHS患者141例中并高血压者69例（高血压组）、血压正常者72例（对照组），进行两组间多导睡眠监测(polysomnography,PSG)资料的比较。结果高血压组患者体块指数(body mass index,BMI)平均(30.67±3.46)kg/m2，与对照组差异有统计学意义(P＜0.05)；高血压组呼吸暂停低通气指数 (apnea-hypopnea index，AHI)平均(54.59±26.48)，明显高于对照组(P＜0.05)；高血压组最低血氧饱和度明显低于对照组(P＜0.05)。睡眠结构比较显示，高血压组和对照组间差异无统计学意义(P＞0.05)。结论中年期高血压OSAHS患者呼吸暂停指数及最低血氧饱和度明显重于血压正常OSAHS患者，但睡眠结构紊乱的程度基本接近。

Polysomnography analyses of obstructive sleep apnea-hypopnea syndrome with hypertension in middle-age patients

To analyze the characteristics of polysomnography in middle-age patients with obstructive sleep apnea hypopnea syndrome(OSAHS) and hypertension. Methods32-polysomnography was performed on 141 middle-age OSAHS patients. Of them, 69 iad hypertension (the hypertension group) and 72 did not (the control group). ResultsThe BMI level was significantly higher in the hypertension group than in the control group ［(30.7±3.5)kg/m2 vs (28.2±3.0)kg/m2, P＜0.05］, also the apnea-hypopnea index of the hypertension group was higher than that of the control group ［(54.6±26.5) vs (42.2±26.3), P＜0.05］. The structure of NREM and REM was not significantly different between the hypertension group and the control group. ConclusionThe sleep structure disorder is similar in the two groups. The low oxygen saturation of blood and apnea-hypopnea index are more serious in middle-age OSAHS patients with hypertension than in patients without hypertension.
