Cellular senescence, classically defined as stable cell cycle arrest, is implicated in biological processes such as embryogenesis, wound healing and ageing. Senescent cells have a complex senescence-associated secretory phenotype (SASP), involving a range of pro-inflammatory factors with important paracrine and autocrine effects on cell and tissue biology. Clinical evidence and experimental studies link cellular senescence, senescent cell accumulation, and the production and release of SASP components with age-related cardiac pathologies such as heart failure, myocardial ischaemia and infarction, and cancer chemotherapy-related cardiotoxicity. However, the precise role of senescent cells in these conditions is unclear and, in some instances, both detrimental and beneficial effects have been reported. The involvement of cellular senescence in other important entities, such as cardiac arrhythmias and remodelling, is poorly understood. In this Review, we summarize the basic biology of cellular senescence and discuss what is known about the role of cellular senescence and the SASP in heart disease. We then consider the various approaches that are being developed to prevent the accumulation of senescent cells and their consequences. Many of these strategies are applicable in vivo and some are being investigated for non-cardiac indications in clinical trials. We end by considering important knowledge gaps, directions for future research and the potential implications for improving the management of patients with heart disease.

细胞衰老在心脏病中的作用:基础生物学和临床相关性

细胞衰老,通常被定义为稳定的细胞周期停滞,与胚胎发生、伤口愈合和衰老等生物过程有关。衰老细胞具有复杂的衰老相关分泌表型 (SASP),涉及一系列对细胞和组织生物学具有重要旁分泌和自分泌作用的促炎因子。临床证据和实验研究将细胞衰老、衰老细胞积累以及 SASP 成分的产生和释放与年龄相关的心脏病理联系起来,例如心力衰竭、心肌缺血和梗塞,以及癌症化疗相关的心脏毒性。然而,衰老细胞在这些情况下的确切作用尚不清楚,在某些情况下,有害和有益的影响都有报道。人们对细胞衰老在其他重要实体(如心律失常和重塑)中的参与知之甚少。在这篇综述中,我们总结了细胞衰老的基础生物学,并讨论了关于细胞衰老和 SASP 在心脏病中的作用的已知信息。然后我们考虑正在开发的各种方法来防止衰老细胞的积累及其后果。许多这些策略都适用于体内,并且一些正在临床试验中针对非心脏适应症进行研究。最后,我们考虑了重要的知识差距、未来研究的方向以及对改善心脏病患者管理的潜在影响。我们总结了细胞衰老的基础生物学,并讨论了关于细胞衰老和 SASP 在心脏病中的作用的已知信息。然后我们考虑正在开发的各种方法来防止衰老细胞的积累及其后果。许多这些策略都适用于体内,并且一些正在临床试验中针对非心脏适应症进行研究。最后,我们考虑了重要的知识差距、未来研究的方向以及对改善心脏病患者管理的潜在影响。我们总结了细胞衰老的基础生物学,并讨论了关于细胞衰老和 SASP 在心脏病中的作用的已知信息。然后我们考虑正在开发的各种方法来防止衰老细胞的积累及其后果。许多这些策略都适用于体内,并且一些正在临床试验中针对非心脏适应症进行研究。最后,我们考虑了重要的知识差距、未来研究的方向以及对改善心脏病患者管理的潜在影响。许多这些策略都适用于体内,并且一些正在临床试验中针对非心脏适应症进行研究。最后,我们考虑了重要的知识差距、未来研究的方向以及对改善心脏病患者管理的潜在影响。许多这些策略都适用于体内,并且一些正在临床试验中针对非心脏适应症进行研究。最后,我们考虑了重要的知识差距、未来研究的方向以及对改善心脏病患者管理的潜在影响。
