Autologous saphenous veins are the most frequently used conduits for coronary and peripheral artery bypass grafting. However, vein graft failure rates of 40–50% within 10 years of the implantation lead to poor long-term outcomes after bypass surgery. Currently, only a few therapeutic approaches for vein graft disease have been successfully translated into clinical practice. Building on the past two decades of advanced understanding of vein graft biology and the pathophysiological mechanisms underlying vein graft disease, nanomedicine-based strategies offer promising opportunities to address this important unmet clinical need. In this Review, we provide deep insight into the latest developments in the rational design and applications of nanoparticles that have the potential to target specific cells during various pathophysiological stages of vein graft disease, including early endothelial dysfunction, intermediate intimal hyperplasia and late-stage accelerated atherosclerosis. Additionally, we underscore the convergence of nanofabricated biomaterials, with a particular focus on hydrogels, external graft support devices and cell-based therapies, alongside bypass surgery to improve local delivery efficiency and therapeutic efficacy. Finally, we provide a specific discussion on the considerations, challenges and novel perspectives for the future clinical translation of nanomedicine for the treatment of vein graft disease. In this Review, Tao and colleagues discuss the design and applications of nanoparticles and nanofabricated biomaterials, such as hydrogels, external graft support devices and cell-based therapies, for the treatment of vein graft disease and highlight the potential of using these nanofabricated biomaterials alongside bypass surgery to improve local delivery efficiency and therapeutic efficacy.
自体大隐静脉是冠状动脉和外周动脉搭桥术中最常用的导管。然而,静脉移植术后 10 年内的失败率高达 40%-50%,导致搭桥手术后的长期疗效不佳。目前,只有少数针对静脉移植疾病的治疗方法已成功应用于临床实践。过去二十年来,人们对静脉移植生物学和静脉移植疾病的病理生理机制有了更深入的了解,在此基础上,基于纳米药物的策略为解决这一尚未满足的重要临床需求提供了大有可为的机会。在本综述中,我们将深入探讨合理设计和应用纳米粒子的最新进展,这些纳米粒子有可能在静脉移植物疾病的不同病理生理阶段靶向特定细胞,包括早期内皮功能障碍、中期内膜增生和晚期加速动脉粥样硬化。此外,我们还强调了纳米加工生物材料与搭桥手术的融合,特别是水凝胶、外部移植支持装置和细胞疗法,以提高局部输送效率和疗效。最后,我们就纳米医学在未来临床应用于治疗静脉移植物疾病的注意事项、挑战和新视角进行了具体讨论。

Cardiovascular disease is the leading cause of morbidity and mortality worldwide, with a substantial amount of health-care resources targeted towards its diagnosis and management. Environmental sustainability in cardiovascular care can have an important role in reducing greenhouse gas emissions and pollution and could be beneficial for improving health metrics and societal well-being and minimizing the cost of health care. In this Review, we discuss the motivations and frameworks for sustainable cardiovascular care with an emphasis on the reduction of the climate-related and environmental effects of cardiovascular care. We also provide an overview of greenhouse gas emissions related to the provision of health care, including their measurement and quantification, carbon accounting, carbon disclosures and climate effects. The principles of life-cycle assessment, waste prevention and circular economics in health care are discussed, and the emissions associated with various sectors of cardiovascular care as well as the rationale for prevention as a powerful approach to reduce these emissions are presented. Finally, we highlight the challenges in environmental sustainability and future directions as applicable to cardiovascular practice. In this Review, Rajagopalan and colleagues summarize the sources of greenhouse gas emissions related to the provision of cardiovascular health care and suggest strategies to reduce carbon emissions and costs, including the use of renewable energy, waste reduction and disease prevention.
心血管疾病是全球发病率和死亡率的主要原因,大量的医疗资源都用于诊断和治疗。心血管病治疗中的环境可持续性可在减少温室气体排放和污染方面发挥重要作用,并有利于改善健康指标和社会福祉,最大限度地降低医疗成本。在本综述中,我们将讨论可持续心血管医疗的动机和框架,重点是减少心血管医疗对气候和环境的影响。我们还概述了与医疗服务相关的温室气体排放,包括其测量和量化、碳核算、碳披露和气候效应。我们还讨论了医疗保健中的生命周期评估、废物预防和循环经济学原则,并介绍了与心血管医疗保健各部门相关的排放量,以及将预防作为减少这些排放量的有效方法的理由。最后,我们强调了环境可持续性方面的挑战以及适用于心血管领域的未来发展方向。

Translation of pathophysiological mechanisms of atrial fibrosis into new diagnostic and therapeutic approaches 将心房纤维化的病理生理机制转化为新的诊断和治疗方法
IF 41.7 1区 医学 Q1 CARDIAC & CARDIOVASCULAR SYSTEMS Pub Date : 2024-10-23 DOI: 10.1038/s41569-024-01088-w

Atrial fibrosis is one of the main manifestations of atrial cardiomyopathy, an array of electrical, mechanical and structural alterations associated with atrial fibrillation (AF), stroke and heart failure. Atrial fibrosis can be both a cause and a consequence of AF and, once present, it accelerates the progression of AF. The pathophysiological mechanisms leading to atrial fibrosis are diverse and include stretch-induced activation of fibroblasts, systemic inflammatory processes, activation of coagulation factors and fibrofatty infiltrations. Importantly, atrial fibrosis can occur in different forms, such as reactive and replacement fibrosis. The diversity of atrial fibrosis mechanisms and patterns depends on sex, age and comorbidity profile, hampering the development of therapeutic strategies. In addition, the presence and severity of comorbidities often change over time, potentially causing temporal changes in the mechanisms underlying atrial fibrosis development. This Review summarizes the latest knowledge on the molecular and cellular mechanisms of atrial fibrosis, its association with comorbidities and the sex-related differences. We describe how the various patterns of atrial fibrosis translate into electrophysiological mechanisms that promote AF, and critically appraise the clinical applicability and limitations of diagnostic tools to quantify atrial fibrosis. Finally, we provide an overview of the newest therapeutic interventions under development and discuss relevant knowledge gaps related to the association between clinical manifestations and pathological mechanisms of atrial fibrosis and to the translation of this knowledge to a clinical setting. In this Review, Schotten and colleagues summarize the latest knowledge on the molecular and cellular mechanisms of atrial fibrosis, describe the electrophysiological manifestations of atrial fibrosis, critically appraise the diagnostic tools to quantify atrial fibrosis, discuss emerging therapeutic interventions, and highlight knowledge gaps and future research directions.
心房纤维化是心房心肌病的主要表现之一,心房心肌病是与心房颤动(房颤)、中风和心力衰竭相关的一系列电气、机械和结构改变。心房纤维化既可能是心房颤动的原因,也可能是心房颤动的结果,一旦出现,就会加速心房颤动的发展。导致心房纤维化的病理生理机制多种多样,包括拉伸引起的成纤维细胞激活、全身炎症过程、凝血因子激活和纤维脂肪浸润。重要的是,心房纤维化可以以不同的形式出现,如反应性纤维化和替代性纤维化。心房纤维化机制和模式的多样性取决于性别、年龄和合并症情况,这阻碍了治疗策略的开发。此外,合并症的存在和严重程度往往会随着时间的推移而发生变化,从而可能导致心房纤维化发生机制的时空变化。本综述总结了有关心房纤维化的分子和细胞机制、其与合并症的关系以及性别差异的最新知识。我们描述了心房纤维化的各种模式如何转化为促进房颤的电生理机制,并对量化心房纤维化的诊断工具的临床适用性和局限性进行了批判性评估。最后,我们概述了正在开发的最新治疗干预措施,并讨论了与心房纤维化的临床表现和病理机制之间的关联以及将这些知识转化到临床环境中的相关知识差距。

Consumption of a high-fat diet leads to the progressive growth of atherosclerotic lesions. Two new studies document that, despite similar overall exposure to high-fat diet over a lifetime, an intermittent consumption of high-fat diet early in life accelerates atherosclerosis compared with continuous consumption of a high-fat diet. The mechanisms for accelerated atherosclerosis include reprogramming of macrophages and neutrophils.

Over the past 50 years, the number and invasiveness of percutaneous cardiovascular procedures globally have increased substantially. However, cardiovascular interventions are inherently associated with a risk of acute brain injury, both periprocedurally and postprocedurally, which impairs medical outcomes and increases health-care costs. Current international clinical guidelines generally do not cover the area of acute brain injury related to cardiovascular invasive procedures. In this international Consensus Statement, we compile the available knowledge (including data on prevalence, pathophysiology, risk factors, clinical presentation and management) to formulate consensus recommendations on the prevention, diagnosis and treatment of acute brain injury caused by cardiovascular interventions. We also identify knowledge gaps and possible future directions in clinical research into acute brain injury related to cardiovascular interventions. Invasive cardiovascular procedures are inherently associated with a risk of acute brain injury, both during and after the intervention. In this international Consensus Statement, the authors provide consensus recommendations on the prevention, diagnosis and treatment of acute brain injury caused by cardiovascular interventions.

Pathophysiology of dilated cardiomyopathy: from mechanisms to precision medicine 扩张型心肌病的病理生理学:从机制到精准医学
IF 41.7 1区 医学 Q1 CARDIAC & CARDIOVASCULAR SYSTEMS Pub Date : 2024-10-11 DOI: 10.1038/s41569-024-01074-2

Dilated cardiomyopathy (DCM) is a complex disease with multiple causes and various pathogenic mechanisms. Despite improvements in the prognosis of patients with DCM in the past decade, this condition remains a leading cause of heart failure and premature death. Conventional treatment for DCM is based on the foundational therapies for heart failure with reduced ejection fraction. However, increasingly, attention is being directed towards individualized treatments and precision medicine. The ability to confirm genetic causality is gradually being complemented by an increased understanding of genotype–phenotype correlations. Non-genetic factors also influence the onset of DCM, and growing evidence links genetic background with concomitant non-genetic triggers or precipitating factors, increasing the extreme complexity of the pathophysiology of DCM. This Review covers the spectrum of pathophysiological mechanisms in DCM, from monogenic causes to the coexistence of genetic abnormalities and triggering environmental factors (the ‘two-hit’ hypothesis). The roles of common genetic variants in the general population and of gene modifiers in disease onset and progression are also discussed. Finally, areas for future research are highlighted, particularly novel therapies, such as small molecules, RNA and gene therapy, and measures for the prevention of arrhythmic death. In this Review, Mestroni and colleagues provide an overview of the pathophysiological mechanisms underlying dilated cardiomyopathy, including both genetic and non-genetic causes, and discuss the development of novel therapies, such as small molecules and gene therapy.
扩张型心肌病(DCM)是一种病因复杂、致病机制多样的疾病。尽管在过去十年中,DCM 患者的预后有所改善,但这种疾病仍然是导致心力衰竭和过早死亡的主要原因。DCM 的传统治疗以射血分数降低型心力衰竭的基础疗法为基础。然而,人们越来越关注个体化治疗和精准医疗。对基因型与表型相关性的进一步了解,逐渐补充了确认遗传因果关系的能力。非遗传因素也会影响 DCM 的发病,越来越多的证据表明,遗传背景与伴随的非遗传诱因或促发因素有关,从而增加了 DCM 病理生理学的极端复杂性。本综述涵盖了 DCM 的各种病理生理学机制,从单基因病因到基因异常与诱发环境因素并存("双击 "假说)。此外,还讨论了普通人群中常见的基因变异以及基因修饰在疾病发生和发展中的作用。最后,强调了未来的研究领域,特别是新型疗法,如小分子、RNA 和基因疗法,以及预防心律失常死亡的措施。

β-blockers after MI: does ABYSS confirm REDUCEd use after all? 心肌梗死后使用 β 受体阻滞剂:ABYSS 是否证实了 REDUCEd 的使用?

In contrast to the ABYSS investigators’ interpretation of the primary results of their trial, we believe that β-blockers can be safely discontinued in the majority of patients after an uncomplicated myocardial infarction. However, in individuals developing symptoms of angina or heart failure, β-blocker treatment remains one of several guideline-recommended therapies.
与 ABYSS 研究人员对其试验主要结果的解释不同,我们认为大多数患者在无并发症的心肌梗死后可以安全地停用 β 受体阻滞剂。不过,对于出现心绞痛或心力衰竭症状的患者,β 受体阻滞剂治疗仍是指南推荐的几种疗法之一。

The burden of atrial fibrillation (AF) is increasing worldwide; however, most existing data on AF epidemiology are from Western regions. According to our analyses, the estimated absolute prevalence of AF in the Asia–Pacific region in 2023 was approximately 80 million, which is much higher than has been calculated for other global regions.
心房颤动(房颤)的负担在全球范围内日益加重;然而,有关房颤流行病学的现有数据大多来自西方地区。根据我们的分析,估计 2023 年亚太地区心房颤动的绝对发病率约为 8000 万,远高于全球其他地区的计算值。

Soil and water pollution and cardiovascular disease 土壤和水污染与心血管疾病
IF 41.7 1区 医学 Q1 CARDIAC & CARDIOVASCULAR SYSTEMS Pub Date : 2024-09-25 DOI: 10.1038/s41569-024-01068-0

Healthy, uncontaminated soils and clean water support all life on Earth and are essential for human health. Chemical pollution of soil, water, air and food is a major environmental threat, leading to an estimated 9 million premature deaths worldwide. The Global Burden of Disease study estimated that pollution was responsible for 5.5 million deaths related to cardiovascular disease (CVD) in 2019. Robust evidence has linked multiple pollutants, including heavy metals, pesticides, dioxins and toxic synthetic chemicals, with increased risk of CVD, and some reports suggest an association between microplastic and nanoplastic particles and CVD. Pollutants in soil diminish its capacity to produce food, leading to crop impurities, malnutrition and disease, and they can seep into rivers, worsening water pollution. Deforestation, wildfires and climate change exacerbate pollution by triggering soil erosion and releasing sequestered pollutants into the air and water. Despite their varied chemical makeup, pollutants induce CVD through common pathophysiological mechanisms involving oxidative stress and inflammation. In this Review, we provide an overview of the relationship between soil and water pollution and human health and pathology, and discuss the prevalence of soil and water pollutants and how they contribute to adverse health effects, focusing on CVD. In this Review, Münzel and colleagues describe the adverse effects of soil and water pollution, including heavy metal, pesticide, and microplastic and nanoplastic pollution, on cardiovascular health and provide an overview of the eco-disruptive causes of this pollution.
健康、无污染的土壤和清洁的水支持着地球上的所有生命,对人类健康至关重要。土壤、水、空气和食物的化学污染是一个主要的环境威胁,估计导致全球 900 万人过早死亡。据全球疾病负担研究估计,2019 年有 550 万人因污染而死于心血管疾病(CVD)。大量证据表明,包括重金属、杀虫剂、二恶英和有毒合成化学品在内的多种污染物与心血管疾病风险增加有关,一些报告还表明微塑料和纳米塑料微粒与心血管疾病有关。土壤中的污染物会削弱其生产粮食的能力,导致作物杂质、营养不良和疾病,而且污染物会渗入河流,加剧水污染。砍伐森林、野火和气候变化会引发土壤侵蚀,并将螯合污染物释放到空气和水中,从而加剧污染。尽管污染物的化学构成各不相同,但它们通过涉及氧化应激和炎症的共同病理生理机制诱发心血管疾病。在本综述中,我们将概述土壤和水污染与人类健康和病理学之间的关系,并讨论土壤和水污染物的普遍性及其如何对健康产生不良影响,重点关注心血管疾病。
