目的应用改进的解剖M型超声心动图技术测量和计算的参数(速度、加速度、相对力)评价冠心病左心室短轴局部心肌运动功能.方法接受经皮冠状动脉介入治疗(PCI)的冠心病(CHD)患者16例,分为A组:单支主要血管狭窄(n=8);B组:多支主要血管狭窄(n=8).经PCI治疗前后采集左心室短轴二尖瓣平面、心尖平面、乳头肌水平各节段(前壁、前间隔、后间隔、后壁、侧壁、下壁)的解剖M型曲线,应用改进的解剖M型超声心动图系统后处理工作站,分别测量3个时相(收缩期、舒张早期、舒张晚期)的峰值速度、加速度、相对力,并进行比较.结果治疗前后速度和加速度的变化收缩期比舒张期明显,B组治疗前后速度和加速度的变化率较A组明显.结论改进的解剖M型超声参数能够反映CHD心肌缺血PCI治疗后舒缩功能的改善情况.

Objective To evaluate the movement function of the left ventricular short-axis with parameters (velocity, acceleration and relatively force) measured with improved anatomical M-mode ultrasound. Methods Sixteen patients with myocardial ischemia coronary heart disease who had taken percutaneous transluminal coronary intervention (PCI) were enrolled. All patients were divided into two groups: group A, single major vascular stenosis (n=8);group B, more major vascular stenosis (n=8). M-mode curves of short-axis sections at mitral valve level, papillary level and apical level were recorded, then the peak myocardial velocities, acceleration and force of the systolic phase, early-diastole phase and end-diastole phase were measured at the post processing station. Results The variety ranges of average velocity and acceleration of the three levels during systolic phase were higher than that during diastole phase. The changing rate of velocity and acceleration in group B was higher than that in group A. Conclusion The new parameters that are measured and calculated with anatomical M-mode ultrasound can reflect the movement functions of coronary heart disease patients taken PCI.
