Anti-ageing interventions for the treatment of cardiovascular disease

As the global demographic landscape continues to shift towards an aged population, so does the medical and socioeconomic burden of cardiovascular diseases. Indeed, ageing is one of, if not, the key risk factor for the development of cardiovascular diseases. However, there are currently no approved cardiovascular therapeutics that primarily target the molecular and cellular mechanisms underlying the ageing process itself. In this review, we present the potential of emerging anti-ageing strategies, including epigenetic rejuvenation, metabolic reprogramming, autophagy(definition) activation, as well as senolytic and anti-inflammatory therapies, in delaying or reversing the development of age-related cardiovascular disorders, while considering potential sex differences. In doing so, we implicate cellular ageing processes in the pathogenesis of several prevalent cardiovascular diseases, such as atherosclerosis, hypertension, various types of cardiomyopathies (including its hypertrophic, ischaemic, dilated, diabetic, and arrhythmogenic forms) and heart failure, particularly that with preserved ejection fraction. Finally, we outline future challenges and steps needed for the implementation of these novel anti-ageing strategies in the clinical setting, with the aim of challenging the long-held notion of ageing as a 'non-modifiable' risk factor for cardiovascular diseases.
