目的应用彩色多普勒超声心动图无创性评价阻塞性睡眠呼吸暂停综合征(OSAS)患者的心脏受累与心功能变化的程度,强调OSAS对心血管功能的影响应引起人们的关注。方法选择经全夜多导睡眠监测仪确诊为OSAS患者68例为病变组,正常对照组20例,对比两组超声心动图心脏结构与血流动力学变化参数。结果OSAS患者心脏结构与心电图异常发生率、舒张末期右室前壁厚度、肺动脉和左(右)肺动脉分支内径、肺动脉血流加速时间、三尖瓣反流程度、三尖瓣反流法估测肺动脉收缩压均明显高于对照组(P<0.01)。结论对常规超声心动图检查显示孤立性右室肥厚而其他检查找不到基础疾病者,应予以高度重视,结合临床考虑到OSAS的可能,及时转专科做出明确诊断,以达到对该病的早期诊断与治疗。
Objective To evaluate the extent of cardiac involvement and cardiac function in patients with obstructive sleep apnea syndrome (OSAS) by color Doppler echocardiography. It is emphasized that the influence of OSAS on cardiovascular function should be of concern. Methods Sixty-eight OSAS patients diagnosed by overnight polysomnography were selected as pathological group and 20 normal control subjects. The cardiac structure and hemodynamic parameters of echocardiography were compared between the two groups. Results The incidence of abnormal cardiac structure and electrocardiogram, the anterior wall thickness of the right ventricular end-diastole, the diameter of the pulmonary artery and left (right) pulmonary artery branches, the acceleration time of pulmonary blood flow, the degree of tricuspid regurgitation, tricuspid regurgitation Pulmonary systolic pressure were significantly higher than the control group (P <0.01). Conclusion Conventional echocardiography showed isolated right ventricular hypertrophy and other tests can not find the underlying diseases, should be highly valued, combined with the clinical consideration of the possibility of OSAS, timely transfer specialist to make a clear diagnosis in order to achieve the disease Early diagnosis and treatment.
