【摘要】 本文分析了50例冠状动脉造影病人左室造影前后左室舒张末期压力的变化与室壁运动、左室功能、冠状动脉病变程度之间的关系。发现左室舒张末期压力的变化与左室电影造影时观察到的室壁运动障碍的程度密切相关;与双维超声心动图所见的室壁节段性运动异常有一定的相关性;与冠状动脉病变无直接关系;与超声射血分数之间无正相关,本文还探讨了左室舒张末期压力改变的直接影响因素是左室收缩顺应性障碍,这可从左室dp/dt的变化得到证实。更多还原

【Abstract】 The relation of LVEDP, ventricular wall motion, LV dp/dt and extent, location and degree of the coronary occlution lesion were analyzed in 50 patients with coronary angiography and left ventriculography. The more serious of the disturbance of wall motion in ventriculography, the risen degree of LVEDP after ventriculography more remarkable.The disturbance of wall motion revealed by the 2-D echocardiography is less accurate than by ventriculography .The rise of LVEDP after ventriculography was relation to abnormall wall motion and compliance of LV. Therefor the LVEDP before and after ventriculography directly depended on LV function.The LV fuction was directly affected by strains and ischemic degree of myocadium. For this reason, the LVEDP, especially the risen degree of LVEDP after ventriculography may be used to appraise cardial function of patients with CAD,and indirectly to evaluate the degree and extent of coronary atery stenosis.更多还原
