动物试验显示，心钻素能增加缺血心肌的局部血流量和增加心内股与心外膜的血流比值。另外，本品还能通过减少静脉回流而降低左室舒张宋庆，对心率和心肌收缩力的影响较小。因此，本品能改善缺血区的心肌灌注而不增加心肌耗氧量。本文采用随机、双盲、交叉试验首次评价了本品对 Animal studies have shown that cardiac rhinosin can increase the local blood flow of ischemic myocardium and increase the ratio of blood flow to the epicardium. In addition, this product can reduce venous return and reduce left ventricular diastolic Song Qing, heart rate and myocardial contractility less affected. Therefore, this product can improve ischemic myocardial perfusion without increasing myocardial oxygen consumption. In this paper, a randomized, double-blind, cross-test for the first time evaluated the product pair
