目的探讨慢性阻塞性肺疾病对冠状动脉粥样硬化性心脏病(CHD)患者心功能的影响。方法选取2013年1月至2015年1月东莞市石碣社区卫生服务中心收治的103例CHD患者作为研究对象,按照是否合并慢性阻塞性肺疾病将其分为CHD合并慢性阻塞性肺疾病组(合并组)和单纯性CHD组(单纯组),分别为60例和43例。采用SEQUOIA512型彩色多普勒超声诊断仪检测患者的左心室舒张末期内径、左心室射血分数、右心室前壁厚度、右心室舒张期内径等。结果合并组患者的主动脉窦部内径、右心室舒张期内径均明显大于单纯组,心率明显高于单纯组,差异均有统计学意义(均P<0.05);合并组患者的左心室舒张末期容量、收缩期容量、左心室射血分数均明显低于单纯组,差异均有统计学意义(均P<0.05);合并组患者的右心房内径明显大于单纯组,差异有统计学意义(P<0.05)。结论合并患有慢性阻塞性肺疾病的CHD患者,其心室容量要比单纯CHD患者更小,整体心功能更差。
Objective To investigate the influence of chronic obstructive pulmonary disease on cardiac function in patients with coronary heart disease (CHD). Methods A total of 103 CHD patients admitted to Shijie Community Health Service Center of Dongguan City between January 2013 and January 2015 were enrolled in this study. Patients with chronic obstructive pulmonary disease (CHD) and chronic obstructive pulmonary disease Combined group) and simple CHD group (simple group), respectively, 60 cases and 43 cases. The left ventricular end-diastolic diameter, left ventricular ejection fraction, right ventricular anterior wall thickness and diastolic diameter of right ventricle were measured by SEQUOIA512 color Doppler ultrasound. Results The diameter of the aortic sinus and the diastolic diameter of the right ventricle in the combined group were significantly higher than those in the simple group, and the heart rate was significantly higher in the combined group than in the simple group (all P <0.05). The left ventricular end- Volume, systolic volume and left ventricular ejection fraction were significantly lower than those in the simple group (all P <0.05). The diameter of the right atrium in the combined group was significantly higher than that in the simple group (P <0.05). Conclusions Patients with CHD complicated with chronic obstructive pulmonary disease have a lower ventricular volume than patients with CHD alone and worse overall cardiac function.
