本文对69例症状限制性平板运动试验的收缩压变化与近期超声心动图心脏收缩和舒张功能的检查进行了比较。根据平板运动试验的结果和收缩压的变化,将病人分为三组:阳性组、血压改变组和血压无改变组。结果表明:三组的收缩功能均无差异。阳性组和血压改变组的舒张早期最大血流速度/舒张晚期最大血流速度(Ev/Av)值明显小于血压无改变组。故认为将收缩压改变达一定程度和Ev/Av值的减小作为心脏功能受损或不同程度心肌缺血的参考依据,可提高判断心功能受损的准确性。 This article compared the changes in systolic blood pressure in 69 patients with symptomatic restrictive treadmill exercise tests with recent echocardiographic cardiac contractility and diastolic function. According to the results of treadmill exercise test and the change of systolic pressure, the patients were divided into three groups: positive group, blood pressure change group and no change of blood pressure group. The results showed that there was no difference in systolic function between the three groups. In the positive group and the group with the change of blood pressure, the maximum diastolic velocity / maximum diastolic velocity (Ev / Av) of the early diastolic phase was significantly lower than that of the no-change blood pressure group. Therefore, it is believed that changing the systolic blood pressure to a certain extent and decreasing the Ev / Av value can serve as the reference basis for impaired cardiac function or myocardial ischemia, which can improve the accuracy of determining the impaired cardiac function.
