乌拉地尔对风心病肺动脉高压的急性降压效应

Effects of Urapidil on Pulmonary Artery Pressure in Rheumatic Heart Disease With Pulmonary Hypertension

目的 :观察乌拉地尔对合并有肺动脉高压的风心病患者右心血流动力学的影响。方法 :以风心病继发肺动脉高压的34例患者为研究对象 ,观察静脉注射0 4mg/kg乌拉地尔后10、40、60min右心血流动力学参数及体循环血压的变化。结果 :乌拉地尔能显著降低风心病患者的肺动脉压、肺循环阻力、肺毛细血管楔嵌压及体循环血压 ,但对肺循环的影响要明显强于体循环 ,且几乎不引起心率及心输出量的改变。未见严重不良反应发生。结论

OBJECTIVE:To investigate the effects of urapidil on the hemodynamics of the right heart in patients with rheumatic heart disease and secondary pulmonary hypertension METHODS:34 patients with rheumatic heart disease and varying degrees of secondary pulmonary hypertension were included in the study In all patients,the hemodynamic parameters and pressure of systemic circulation were determined before and 20,40,60 min after urapidil intraverous injection in a dose of 0 4mg/kg RESULTS:Pulmonary artery pressure,pulmonary vascular resistance,pulmonary capillary wedge pressure and systemic artery pressure were decreased after urapidil injection The reduction of resistance in the pulmonary vascular bed was greater than that in the systemic circulation There were no significant alterations in heart rate and cardic output No serious side-effects were observed in the study CONCLUSION:Urapidil may be a promising drug in the treatment of patients with pulmonary hypertension due to rheumatic heart disease
