Inotropes aim at increasing cardiac output by enhancing cardiac contractility. They constitute the third pharmacological pillar in the treatment of patients with decompensated heart failure, the other two being diuretics and vasodilators. Three classes of parenterally administered inotropes are currently indicated for decompensated heart failure, (i) the beta adrenergic agonists, including dopamine and dobutamine and also the catecholamines epinephrine and norepinephrine, (ii) the phosphodiesterase III inhibitor milrinone and (iii) the calcium sensitizer levosimendan. These three families of drugs share some pharmacologic traits, but differ profoundly in many of their pleiotropic effects. Identifying the patients in need of inotropic support and selecting the proper inotrope in each case remain challenging. The present consensus, derived by a panel meeting of experts from 21 countries, aims at addressing this very issue in the setting of both acute and advanced heart failure.
正性肌力药物通过增强心肌收缩力来增加心输出量。它们构成了治疗失代偿性心力衰竭的第三个药理学支柱,另外两个是利尿剂和血管扩张剂。目前有三类静脉内给予的正性肌力药物可用于治疗失代偿性心力衰竭:(i)β肾上腺素能激动剂,包括多巴胺和多巴酚丁胺,以及儿茶酚胺肾上腺素和去甲肾上腺素,(ii)磷酸二酯酶 III 抑制剂米力农,(iii)钙增敏剂左西孟旦。这三类药物具有一些药理学特征,但在许多多效性作用方面存在显著差异。确定需要正性肌力支持的患者,并在每种情况下选择合适的正性肌力药物仍然具有挑战性。本共识是由来自 21 个国家的专家小组会议制定的,旨在解决急性和晚期心力衰竭患者的这一问题。
