Cardiac ageing: extrinsic and intrinsic factors in cellular renewal and senescence
Various intrinsic and extrinsic factors influence the balance between cellular renewal and senescence in the ageing heart. In this Review, Gude and colleagues discuss these factors, including environment, lifestyle, genetics and epigenetics, inflammation, and oxidative stress, and how they might be therapeutically targeted.

Mitochondrial quality control mechanisms as molecular targets in cardiac ageing
Alterations in mitochondrial function, which are amplified by defective mitochondrial quality control (MQC) mechanisms, are major contributing factors to cardiac senescence. In this Review, the authors discuss the mechanisms linking defective MQC to organelle dysfunction in the context of cardiac ageing and consider how these pathways might be targeted for the prevention and treatment of age-related heart dysfunction.

The roles of senescence and telomere shortening in cardiovascular disease
Telomere shortening, along with various other endogenous and environmental factors, can drive cells into senescence, which is involved in the complex process of biological ageing. In this Review, Fyhrquist and colleagues discuss the associations between cardiovascular risk factors and telomere shortening, and whether cellular senescence has a causal role in conditions such as atherosclerosis, heart failure, and hypertension.
