结果表明，应用波生坦后，尽管收缩期和舒张期血压没有变化，收缩末期和舒张期心室体积比例明显升高。
Peak systolic and diastolic strain rates also increased significantly after bosentan treatment, the results indicate, although systolic and diastolic blood pressures were not affected.
方法采用高分辨力超声无创性检测血管内皮依赖性舒张功能的方法比较收缩期和舒张期高血压（SDH）与正常血压组血流介导性舒张（FMD）与反应性充血的血管内皮依赖性舒张功能。
Methods A non-invasive high-resolution ultrasound was used to detect the flow-mediated dilatation (FMD) and the change of blood flow volume of reactive hyperaemia in SDH and the control.
它包括心率储备、舒张期储备和收缩期储备等。
It includes the heart rate reserve, diastolic and systolic reserve and other reserves.
