Abstract

To study the ventriculoarterial coupling in diabetic patients with myocardial infarction (MI), 26 diabetic and 34 nondiabetic patients were investigated using radionuclide angiography in the 3rd week after acute MI. Effective arterial elastance was nearly one half of left ventricular end-systolic elastance in nondiabetic patients. On the other hand, effective arterial elastance was twice left ventricular end-systolic elastance in diabetic patients. These data suggest that a decrease in left ventricular contractility and an increase in effective arterial elastance lead to increased potential energy and decreased work efficiency in diabetic patients.

摘要

为研究糖尿病合并心肌梗死（MI）患者的心室动脉耦联情况，在急性心肌梗死后第3周，对26例糖尿病患者和34例非糖尿病患者进行了放射性核素血管造影检查。非糖尿病患者的有效动脉弹性几乎是左心室收缩末期弹性的一半。另一方面，糖尿病患者的有效动脉弹性是左心室收缩末期弹性的两倍。这些数据表明，糖尿病患者左心室收缩力降低和有效动脉弹性增加导致势能增加和工作效率降低。
