血管扩张疗法的理论急性心肌梗塞(AMI)伴心力衰竭(以下简称心衰)患者的血液动力学特征是,体循环血管阻力和左室充盈压(LVFP)增加,心排出量减少,导致肾血流灌注减少而加重钠和水潴留;一般伴有体、肺循环静脉张力升高.治疗的目标是:(1)在降低 LVFP 的同时增加心排出量;(2)限制心肌梗塞时的组织损伤程度,使心脏指数增加,周围营养灌注改善。
Theory of Vasodilation Therapy The hemodynamic characteristics of patients with acute myocardial infarction (AMI) with heart failure (HF) are increased systemic vascular resistance and increased left ventricular filling pressure (LVFP) and reduced cardiac output leading to renal blood flow Reduced perfusion and aggravate the sodium and water retention; generally associated with body, pulmonary venous tension increases. The goal of treatment is: (1) reduce cardiac output while reducing LVFP; (2) limit the extent of tissue damage in myocardial infarction, Increases cardiac index, improved perfusion around the nutrition.
