In 57 patients with stenosis or occlusion of the terminal segment of abdominal aorta the authors measured the myocardial mass and the end diastolic volume of the left ventricle before the operation and 15-20 days after it (shunting or prosthesis of bifurcation of the abdominal aorta). Prior to operation increase of the myocardial mass of the left ventricle was found in 77.2% of patients. Patients with normal blood pressure had an increase in the myocardial mass at the expense of the thickening of the ventricular wall only, in patients with increased BP there was an increase in the thickness of the ventricular wall and also in the end diastolic volume. After the operation in patients with normal BP myocardial mass of the left ventricle reverted to normal. In patients with high BP the myocardial mass and the end diastolic volume of the left ventricle decreased. Myocardial hypertrophy in the patients studied is due to the increased resistance to blood ejection from the left ventricle caused by stenosis or occlusion of the abdominal aorta.
在57例腹主动脉末段狭窄或闭塞患者中，作者测量了手术前及术后15 - 20天（行分流术或腹主动脉分叉部假体植入术）左心室的心肌质量和舒张末期容积。术前，77.2%的患者左心室心肌质量增加。血压正常的患者，心肌质量增加仅以心室壁增厚为代价；血压升高的患者，心室壁厚度增加，舒张末期容积也增加。术后，血压正常的患者左心室心肌质量恢复正常。血压高的患者，左心室心肌质量和舒张末期容积减小。所研究患者的心肌肥大是由于腹主动脉狭窄或闭塞导致左心室射血阻力增加所致。
