The advent of newly available medical therapies for heart failure with reduced ejection fraction (HFrEF) has resulted in many potential therapeutic combinations, increasing treatment complexity. Publication of expert consensus guidelines and initiatives aimed to improve implementation of treatment has emphasized sequential stepwise initiation and titration of medical therapy, which is labour intensive. Data taken from heart failure registries show suboptimal use of medications, prolonged titration times, and consequently little change in dose intensity, all of which indicate therapeutic inertia. Recently published evidence indicates that 4 medication classes-renin-angiotensin-neprilysin inhibitors, β-blockers, mineralocorticoid antagonists, and sodium-glucose cotransporter inhibitors-which we refer to as Foundational Therapy, confer rapid and robust reduction in both morbidity and mortality in most patients with HFrEF and that they work in additive fashion. Additional morbidity and mortality may be observed following addition of several personalized therapies in specific subgroups of patients. In this review, we discuss mechanisms of action of these therapies and propose a framework for their implementation, based on several principles. These include the critical importance of rapid initiation of all 4 Foundational Therapies followed by their titration to target doses, emphasis on multiple simultaneous drug changes with each patient encounter, attention to patient-specific factors in choice of medication class, leveraging inpatient care, use of the entire health care team, and alternative (ie, virtual visits) modes of care. We have incorporated these principles into a Cluster Scheme designed to facilitate timely and optimal medical treatment for patients with HFrEF.
新型心力衰竭射血分数降低型(HFrEF)治疗方法的出现导致了许多潜在的治疗组合,增加了治疗的复杂性。专家共识指南和旨在改善治疗实施的倡议的发布强调了医学治疗的序贯逐步启动和滴定,这是劳动密集型的。来自心力衰竭登记处的数据表明,药物的使用不理想,滴定时间延长,因此剂量强度变化不大,所有这些都表明存在治疗惰性。最近发表的证据表明,我们称之为基础治疗的 4 类药物——肾素-血管紧张素-脑啡肽酶抑制剂、β 受体阻滞剂、盐皮质激素受体拮抗剂和钠-葡萄糖共转运蛋白抑制剂,可使大多数 HFrEF 患者的发病率和死亡率迅速而显著降低,并且它们具有相加作用。在特定的患者亚组中添加几种个性化治疗后,可能会观察到额外的发病率和死亡率。在这篇综述中,我们讨论了这些治疗方法的作用机制,并根据几个原则提出了实施这些治疗方法的框架。这些原则包括迅速启动所有 4 种基础治疗方法并将其滴定至目标剂量的重要性、强调每位患者同时进行多次药物调整、在选择药物类别时关注患者的具体因素、利用住院护理、使用整个医疗团队以及替代(即虚拟就诊)护理模式。我们已经将这些原则纳入了一个聚类方案中,旨在为 HFrEF 患者提供及时和最佳的医疗治疗。
