以往只是研究单一血流动力学参数和左室充盈的关系,而本研究评估了心梗患者和正常人群各血流动力学参数对左室充盈的相对影响。 方法 心梗患者15例,对照组10例。除短效硝酸酯外,其他心脏活性药物在研究前三天停用,经心导管作左室造影,采用电影照相技术获取图像,配以同步高精度左室压力 In the past, only the relationship between single hemodynamic parameters and left ventricular filling was studied. However, this study evaluated the relative effects of hemodynamic parameters on left ventricular filling in patients with myocardial infarction and normal controls. Methods 15 cases of myocardial infarction patients, control group of 10 cases. In addition to short-acting nitrates, other cardioactive drugs were discontinued three days prior to the study, transcatheter catheterization for left ventricular angiography, and acquisition of images using cine photographic techniques with simultaneous high-precision left ventricular pressure
