目的:探讨195例冠心病患者多谱勒超声心动图变化特征与脉象要素的相关性,为发展无创的脉诊检测技术提供理论支持。方法:运用M egas多谱勒彩色超声仪采集冠心病患者心脏彩色多谱勒超声心动图指标。结果:冠心病患者脉象要素-脉位、脉力、脉紧张度、脉流利度4方面与超声指标存在不同程度的相关:冠心病脉有力者表现为主动脉流速、肺动脉流速升高,二尖瓣E峰降低;脉紧张者表现为主动脉流速、肺动脉流速增大,而左室舒张末期内径、左室收缩末期内径、二尖瓣E峰、二尖瓣A峰减小;脉滑者表现为主动脉流速、肺动脉流速减低,二尖瓣A峰、射血分数增高;冠心病脉位浮者表现为心脏室间隔厚度、左室后壁厚度减小,主动脉流速、肺动脉流速、二尖瓣E峰有降低趋势。结论:结合多学科研究的手段,可寻找到冠心病患者脉象构成要素的量化指标。
Objective: To investigate the correlation between Doppler echocardiographic features and pulse components in 195 patients with coronary heart disease, and to provide theoretical support for the development of noninvasive pulse diagnostic techniques. Methods: Cardiac Doppler echocardiography was performed in patients with coronary heart disease by M egas Doppler color sonography. Results: There were some correlations between the pulsatile factors of pulse wave, pulse force, pulse tension and pulse fluency in patients with coronary heart disease and ultrasonic indexes: coronary flow in patients with coronary artery disease manifested as aortic flow velocity, pulmonary artery flow velocity increased, E-peak decreased; pulse tension showed aortic flow velocity, pulmonary artery velocity increased, while the left ventricular end-diastolic diameter, end-systolic diameter, mitral E peak, mitral A peak decreased; Aortic flow velocity, pulmonary artery velocity decreased, mitral a peak, ejection fraction increased; coronary artery pulse floating body showed ventricular septal thickness, left ventricular wall thickness decreases, aortic flow, pulmonary artery flow velocity, tip Peak E peak decreased. Conclusion: Combined with multidisciplinary research methods, quantitative indicators of pulse components in patients with coronary heart disease can be found.
