Cardiovascular diseases are the leading cause of death globally, with cardiac arrhythmias contributing substantially to this burden. Gene therapy, which directly targets the underlying disease pathobiology, offers an appealing treatment strategy for cardiac arrhythmias owing to its potential as a one-time, curative solution. Over the past two decades, substantial efforts have been made to develop new gene therapy approaches that overcome the limitations of conventional treatments. In this Review, we describe the rationale for gene therapy to treat cardiac arrhythmias; discuss advantages and disadvantages of gene silencing, gene replacement, gene suppression-and-replacement and gene editing technologies; summarize vector modalities and delivery approaches used in the field; present examples of gene therapy strategies used for atrial and ventricular arrhythmias; and highlight the current challenges and limitations in the gene therapy field. In this Review, Ackerman and colleagues describe the rationale for gene therapy to treat cardiac arrhythmias; discuss advantages and disadvantages of gene silencing, replacement and editing technologies; summarize vector modalities and delivery approaches; present examples of gene therapy strategies used for atrial and ventricular arrhythmias; and highlight the current challenges and limitations in the gene therapy field.
心血管疾病是全球死亡的主要原因,心律失常在很大程度上加重了这一负担。基因治疗,直接针对潜在的疾病病理生物学,提供了一个有吸引力的治疗策略心律失常由于其潜在的一次性,可治愈的解决方案。在过去的二十年里,人们已经做出了巨大的努力来开发新的基因治疗方法,克服了传统治疗方法的局限性。在这篇综述中,我们描述了基因疗法治疗心律失常的基本原理;讨论了基因沉默、基因替代、基因抑制与替代和基因编辑技术的优缺点;总结在实地使用的病媒方式和交付方法;目前基因治疗策略用于心房和室性心律失常的例子;并强调当前基因治疗领域的挑战和局限性。

Endothelial cell metabolism in cardiovascular physiology and disease 内皮细胞代谢在心血管生理和疾病中的作用
IF 44.2 1区 医学 Q1 CARDIAC & CARDIOVASCULAR SYSTEMS Pub Date : 2025-05-09 DOI: 10.1038/s41569-025-01162-x

Endothelial cells are multifunctional cells that form the inner layer of blood vessels and have a crucial role in vasoreactivity, angiogenesis, immunomodulation, nutrient uptake and coagulation. Endothelial cells have unique metabolism and are metabolically heterogeneous. The microenvironment and metabolism of endothelial cells contribute to endothelial cell heterogeneity and metabolic specialization. Endothelial cell dysfunction is an early event in the development of several cardiovascular diseases and has been shown, at least to some extent, to be driven by metabolic changes preceding the manifestation of clinical symptoms. Diabetes mellitus, hypertension, obesity and chronic kidney disease are all risk factors for cardiovascular disease. Changes in endothelial cell metabolism induced by these cardiometabolic stressors accelerate the accumulation of dysfunctional endothelial cells in tissues and the development of cardiovascular disease. In this Review, we discuss the diversity of metabolic programmes that control endothelial cell function in the cardiovascular system and how these metabolic programmes are perturbed in different cardiovascular diseases in a disease-specific manner. Finally, we discuss the potential and challenges of targeting endothelial cell metabolism for the treatment of cardiovascular diseases. In this Review, the authors describe the metabolic programmes that control endothelial cell function in the cardiovascular system, discuss the role of endothelial cell metabolism in different cardiovascular diseases, and highlight the therapeutic potential and challenges of targeting endothelial cell metabolism to treat cardiovascular diseases.
内皮细胞是形成血管内层的多功能细胞,在血管反应性、血管生成、免疫调节、营养摄取和凝血等方面起着至关重要的作用。内皮细胞具有独特的代谢和代谢异质性。内皮细胞的微环境和代谢导致了内皮细胞的异质性和代谢特化。内皮细胞功能障碍是几种心血管疾病发展的早期事件,至少在某种程度上,已被证明是由临床症状表现之前的代谢变化所驱动的。糖尿病、高血压、肥胖和慢性肾脏疾病都是心血管疾病的危险因素。这些心脏代谢应激源引起的内皮细胞代谢变化加速了功能失调的内皮细胞在组织中的积累和心血管疾病的发展。在这篇综述中,我们讨论了控制心血管系统内皮细胞功能的代谢程序的多样性,以及这些代谢程序如何在不同的心血管疾病中以疾病特异性的方式受到干扰。最后,我们讨论了靶向内皮细胞代谢治疗心血管疾病的潜力和挑战。

Redefining respiratory sinus arrhythmia as respiratory heart rate variability: an international Expert Recommendation for terminological clarity 将呼吸性窦性心律失常重新定义为呼吸性心率变异性:术语清晰度的国际专家建议。

The variation of heart rate in phase with breathing, known as ‘respiratory sinus arrhythmia’ (RSA), is a physiological phenomenon present in all air-breathing vertebrates. RSA arises from the interaction of several physiological mechanisms but is primarily mediated by rhythmic changes in cardiac parasympathetic (vagal) activity, increasing heart rate during inspiration and decreasing heart rate during expiration. RSA amplitude is an indicator of autonomic and cardiac health; RSA is diminished or absent in common pathological conditions such as chronic heart failure and hypertension. In this Expert Recommendation, we argue that the term ‘RSA’, although historically important, is semantically inaccurate and carries misleading pathological connotations, contributing to misunderstanding and misinterpretation of the origin and the physiological importance of the phenomenon. We propose replacing ‘RSA’ with the term ‘respiratory heart rate variability’ (RespHRV), which avoids pathological connotations and emphasizes the specific respiratory contribution to heart rate variability. We clarify that RespHRV encompasses respiratory-related heart rate variations in both the low-frequency and high-frequency bands traditionally defined in heart rate variability analysis, and that its amplitude should not be misconstrued as a measure of vagal tone. Adopting the proposed term ‘RespHRV’ is expected to unify understanding and stimulate further experimental and clinical research into the physiological mechanisms and functional importance of this phenomenon. The physiological phenomenon whereby heart rate varies in phase with breathing in vertebrates has been known as ‘respiratory sinus arrhythmia’. In this Expert Recommendation, the authors argue that this terminology is potentially misleading and propose replacing it with the term ‘respiratory heart rate variability’, which avoids pathological connotations.
心率随呼吸同步变化,被称为“呼吸性窦性心律失常”(RSA),是所有呼吸空气的脊椎动物都存在的一种生理现象。RSA产生于多种生理机制的相互作用,但主要是由心脏副交感神经(迷走神经)活动的节律性变化介导的,吸气时心率增加,呼气时心率降低。RSA振幅是自主神经和心脏健康的指标;在常见的病理条件下,如慢性心力衰竭和高血压,RSA减少或不存在。在本专家建议中,我们认为术语“RSA”虽然具有重要的历史意义,但在语义上是不准确的,并且带有误导性的病理内涵,导致对该现象的起源和生理重要性的误解和误解。我们建议用术语“呼吸性心率变异性”(RespHRV)代替“RSA”,这避免了病理内涵,并强调了呼吸对心率变异性的特定贡献。我们澄清,RespHRV包括低频和高频呼吸相关的心率变化,其振幅不应被误解为迷走神经张力的测量。采用拟议的术语“RespHRV”有望统一认识,并促进对该现象的生理机制和功能重要性的进一步实验和临床研究。

Decongestion in heart failure: medical and device therapies 心力衰竭的去充血:医疗和器械疗法
IF 44.2 1区 医学 Q1 CARDIAC & CARDIOVASCULAR SYSTEMS Pub Date : 2025-04-28 DOI: 10.1038/s41569-025-01152-z

Heart failure is a leading cause of hospitalization worldwide, and congestion is the predominant cause of heart failure symptoms and hospitalization. The primary therapy used to treat and prevent congestion has historically been loop diuretics. However, many patients are discharged from hospital with residual congestion, which is associated with persistent heart failure symptoms, adverse outcomes and hospital readmission. Multiple medical strategies and devices have been and are being investigated with the aim of improving decongestion and subsequent heart failure outcomes. Numerous questions exist about the design of clinical trials to test emerging medical and device therapies, including the magnitude of benefit on congestive, kidney and post-discharge outcomes relative to conventional decongestion practices, and how best to implement novel therapies. In this Review, we discuss emerging medical and device strategies targeting congestion in patients with heart failure. Congestion is the predominant cause of heart failure symptoms and hospitalization. In this Review, Testani and colleagues discuss established and emerging medical and device strategies to treat congestion and improve outcomes in patients with heart failure.
心力衰竭是世界范围内住院的主要原因,而充血是心力衰竭症状和住院的主要原因。用于治疗和预防充血的主要疗法历来是循环利尿剂。然而,许多患者出院时伴有残余充血,这与持续的心力衰竭症状、不良后果和再入院有关。多种医疗策略和设备已经并且正在被研究,目的是改善去充血和随后的心力衰竭结果。关于测试新兴医疗和设备疗法的临床试验设计存在许多问题,包括相对于传统的去充血做法对充血性、肾脏和出院后结果的益处程度,以及如何最好地实施新疗法。在这篇综述中,我们讨论了针对心力衰竭患者充血的新兴医疗和设备策略。
