充血性心力衰竭是一种常见病,也是医学上的难题。虽然总体上心血管疾病的死亡率在下降,但由心衰引起的死亡率却在不断增加。充血性心力衰竭的治疗,除了使用增强心肌收缩力的药物强心药外,还趋向使用血管舒张药来减少血管的阻力以及使用利尿药来减少循环血容量。强心甙是应用多年合成的的强心药,但其安全范围小,而数千种合成的强心甙类似物疗效没有显著的改善,故人们致力于寻找 Congestive heart failure is a common disease, but also medical problems. Although the overall cardiovascular mortality rate is declining, the rate of death from heart failure is on the rise. Treatment of congestive heart failure, in addition to the use of drugs to enhance myocardial contractility cardiac medicine, but also tend to use vasodilators to reduce vascular resistance and the use of diuretics to reduce circulating blood volume. Cardiac glycosides are cardigenics that have been used for many years in their synthesis but their safety profile is small, while the efficacy of thousands of synthetic cardiac glycosides has not been significantly improved, so people are looking for ways to find
