本文观察20例肺心病患者经川芎嗪治疗后,其肺血液动力学和右心功能的即时(用药后30、60分钟,停药后1小时)变化。结果:用川芎嗪后30分钟肺动脉平均压(AP)和肺血管阻力(PVR)即开始降低,心率变慢,心输出量(CO)增加。除HR变慢的作用可持续至停药后60分钟外,AP和PVR均在停药后60分钟内回升,其值与用药前相比无显著性差异(P>0.05)。肺血流图除B-YI用药前后和B-Y间期用药后
In this paper, 20 patients with pulmonary heart disease after tetramethylpyrazine treatment of pulmonary hemodynamics and right heart function (30,60 minutes after treatment, 1 hour after stopping change) changes. Results: Pulmonary arterial pressure (AP) and pulmonary vascular resistance (PVR) decreased with ligustrazine 30 minutes after the infusion of ligustrazine, the heart rate slowed and the cardiac output (CO) increased. In addition to the role of HR slowed down to 60 minutes after stopping the drug, both AP and PVR rose within 60 minutes after stopping the drug. The values were not significantly different from those before treatment (P> 0.05). Pulmonary blood flow in addition to B-YI before and after treatment and B-Y interval after treatment
