睡眠呼吸障碍与运动时血压变化关系的研究

The relationship between sleep apnea-hypopnea syndrome and the variation of blood pressure in exercise

目的 阻塞性睡眠呼吸暂停综合征的程度与运动时血压反应的相关分析。方法 将未服用降压药的阻塞性睡眠呼吸暂停综合征患者 49例作为对象 ,用自行车式测量计进行运动试验 ,测量血压、脉搏、血中乳酸值及血气。再将安静时血压、运动负荷时各血压变化量与肥胖指数、临床症状、睡眠多导监测仪检测的夜间血氧饱和度最低值的平均值等数值进行分析。结果 运动负荷时的血压变化量与临床症状、夜间血氧饱和度最低值平均值间显示有相关性 ,而与体重指数无相关性。

Objective To investigate the relative relationship between the degrees of seriousness of obstructive sleep apnea hypopnea syndrome and the variation of blood pressure in exercise Methods 49 patients with obstructive sleep apnea hypopnea syndrome without using anti hypertension drugs, were used as our objectives We performed the exercise test with bicycle like instrument During the test, we measured the blood pressure, plasma lactic acid and arterial blood gases Then we analysed the blood pressure in exercise, BMI, clinical symptoms and the mean of the lowest SpO2 measured by over night polysomnography Results The variation of blood pressure in exercise was related to the clinical symptoms and the mean of the lowest SpO2, but not to the BMI Conclusion The degrees of seriousness of obstructive sleep apnea hypopnea syndrome may be related to the elevation of blood pressure
