目的 探讨鼾症对老年退行性心脏瓣膜病 (DCVD)的影响和对心脏瓣膜结构和功能损害的特征。方法 对 4 5 2例老年鼾症患者与 4 5 2例非鼾症老人进行队列研究 ,采用彩色多普勒超声心动图检查心脏瓣膜的结构与功能。结果 老年鼾症组DCVD的发病率及严重程度与非鼾症组DCVD的发病率及严重程度相比 ,差别有非常显著性意义(P <0 0 1)。结论 鼾症可能是导致DCVD的原因之一 ,是加重心脏瓣膜结构损害与功能障碍的因素
Objective To investigate the effect of snoring on senile degenerative heart valve disease (DCVD) and the characteristics of cardiac valve structure and dysfunction. Methods A cohort study was conducted in 452 elderly snoring patients and 452 non-snoring elderly patients. Color Doppler echocardiography was used to examine the structure and function of heart valves. Results The incidence and severity of DCVD in elderly snoring group were significantly different from the incidence and severity of DCVD in non-snoring group (P <0.01). Conclusion Snoring may be one of the reasons leading to DCVD, which is the factor that aggravates the damage and dysfunction of heart valve structure
