摘要
目的探讨阻塞性睡眠呼吸暂停综合征(OSAS)与左室舒张功能的关系。方法对20例新诊断为OSAS的患者(OS-AS组)及15名健康人(正常对照组)行超声心动图检查。结果与正常对照组相比,OSAS组左室等容舒张时间延长(P<0.05),E/A下降(P<0.05),E峰减速时间延长(P<0.05);两组受检者左室内径(LVSD、LVDD)、室间隔厚度、左室后壁厚度等指标无显著性差异。结论OSAS与左室舒张功能下降有关。
Objective To explore the relationship between obstructive sleep apnea syndrome（OSAS）and the left ventricular diastolic dysfunction.Methods 20 consecutive newly diagnosed middle-aged OSAS patients（OSAS group）with neither controllable factors nor conditions affecting left ventricular diastolic function and 15 healthy control subjects（control group）were examined with echocardiography.Results The OSAS group exhibited left ventricular diastolic dysfunction compared with the control group,including increase of isovolumic relaxation time（P〈0.05）and mitral deceleration time（P〈0.05）,decrease of E/A.There was no difference between tow groups in interventricular systolic thickness,posterior wall thickness,left ventricular systolic diameter,left ventricular diastolic diameter and others.Conclusion OSAS may be related with the left ventricular diastolic dysfunction.
