减少左心室喷血阻抗可以改善左心衰竭的血液动力学。血管扩张药能减低左室充盈压(LVFP)和增加心排出量,仅略降低动脉血压。文献报道用血管扩张药物治疗高血压或急性心肌梗塞并发的急性左心衰竭和缺血性、原发性心肌病或二尖瓣关闭不全所引起
Reduce left ventricular splat impedance can improve hemodynamics of left ventricular failure. Vasodilators reduce left ventricular filling pressure (LVFP) and increase cardiac output, with only a slight decrease in arterial blood pressure. Reported in the literature with vasodilator drugs for the treatment of hypertension or acute myocardial infarction complicated by acute left heart failure and ischemic, primary cardiomyopathy or mitral regurgitation caused
