非甙类变力性药物——β-肾上腺素能受体兴奋剂与非甙类、非肾上腺素能强心药有显著正性变力作用。一些制剂还兼有选择性或非选择性扩张血管作用,并可使原来对洋地黄、利尿剂及扩血管药反应低下的严重充血性心力衰竭患者的血流动力学和临床症状获得改善。因此,值得在今后的临床实践中进一步验证和深入研究。 Non-glycosidic drug-β-adrenergic receptor agonists and non-glycosides, non-adrenergic cardiopeptiform significant positive force. Some preparations also have selective or non-selective dilation of blood vessels, and can make the original digitalis, diuretics and vasodilator drugs in patients with severe congestive heart failure improved hemodynamics and clinical symptoms. Therefore, it is worth further validation and further study in the future clinical practice.
