摘　　要：目的应用二尖瓣环自动追踪技术评价冠状动脉粥样硬化性心脏病(以下简称冠心病)病人左心室收缩功能。并研究二尖瓣环自动追踪技术与改良Simpson法及左室造影法对测量左心室收缩功能间的相关性。方法受试者共110例,其中健康志愿者47例,冠心病病人63例。所有受试者取心尖四腔心,应用改良Simpson法测量左室舒张末容积、收缩末容积、每搏量、心输出量、左室射血分数、每搏指数、心排指数,转换二尖瓣环自动追踪技术模式分别测量以上指标。采用相关分析,比较二尖瓣环自动追踪技术与改良Simpson法测量左室功能的相关性。并且比较2种方法对于左室指标的测量有无差异。30例冠心病病人进行左室造影,并与二尖瓣环自动追踪技术测量指标进行相关分析,且比较左室造影、二尖瓣环自动追踪技术、改良Simpson法对于左室指标测量有无差异。结果在正常人中2种方法测量指标相关系数分别为:左室舒张末容积0.838、收缩末容积0.917、每搏量0.611、心输出量0.579、左室射血分数0.648、每搏指数0.514、心排指数0.541。在冠心病病人中2种方法测量指标相关系数分别为:左室舒张末容积0.875、收缩末容积0.912、每搏量0.693、心输出量0.664、左室射血分数0.725、每搏指数0.688、心排指数0.684。所有受试者2种方法测量指标相关系数分别为:左室舒张末容积0.850、收缩末容积0.920、每搏量0.627、心输出量0.604、左室射血分数0.711、每搏指数0.617、心排指数0.631。二尖瓣环自动追踪技术与左室造影法对左室收缩功能指标的相关系数分别为:左室舒张末容积0.842、收缩末容积0.892、每搏量0.651、心输出量0.614、左室射血分数0.709、每搏指数0.616、心排指数0.630。二尖瓣环自动追踪技术与改良Simpson法及左室造影法对于左室功能指标测量差异无统计学意义。结论二尖瓣环自动追踪技术与�Objective To examine the clinical application of automated mitral annular tracking for assessing left ventricular systolic function in coronary atherosclerotic heart disease （CAD）. The automated mitral annular tracking technology and improved Simpson method and left ventricular angiography method measured the correlation between left ventricular systolic function. Methods The subjects were 110 cases include 47 healthy volunteers and 63 cases of patients with coronary heart disease. End-diastolic volume （EDV）, end-systolic volume （ESV）, stroke volume （SV）, cardiac output （CO）, left ventricular ejection fraction （LVEF）, stroke index （SI） and cardiac index （CI） were detected by automated mitral annular tracking and modified Simpson method in the apical window at 4-chamber, respectively. All parameters were compared between the two ways and were determined with the correlation analysis. Thirty cases of CAD patients with left ventricular angiography were associated with automated mitral annular tracking measure for analysis. The left ventricular angiography, automated mitral annular tracking, modified Simpson method were used to measure the difference between left ventricular indicators. Results The r of EDV, ESV, SV, CO, LVEF, SI and CI were 0.838, 0.917, 0.611, 0.579, 0.648, 0.514 and 0.541 between automated mitral annular tracking and modified Simpson method in normal subjects. The r of EDV, ESV, SV, CO, LVEF, SI and CI were 0.875, 0.912, 0.693, 0.664, 0.725, 0.688 and 0.684 between automated mitral annular tracking and modified Simpson method in CAD. The r of EDV, ESV, SV, CO, LVEF, SI and CI were 0.850, 0.920, 0.627, 0.604, 0.711, 0.617 and 0.631 between automated mitral annular tracking and modified Simpson method in all subjects. The r of EDV, ESV, SV, CO, LVEF, SI and CI were 0.842, 0.892, 0.651, 0.614, 0.709, 0.616 and 0.630 between automated mitral annular tracking and left ventricular angiography in 30 CAD.
