Most acquired cardiovascular diseases are more common in older people, and the biological mechanisms and manifestations of aging provide insight into cardiovascular pathophysiology. Measuring aging within the cardiovascular system may help to better understand risk profiles for specific individuals and direct targeted preventative therapy. In this review, we explore telomere attrition, cellular senescence, epigenetic modifications, and mitochondrial dysfunction as key molecular mechanisms of aging. These phenomena are associated with cardiovascular disease through endothelial dysfunction and systemic inflammation, which are measurable in clinical practice with a variety of clinical, laboratory, and imaging techniques. Finally, we discuss that the next tools for modelling cardiovascular aging must be capable of incorporating a vast amount of diverse data from a given patient, pointing to recent developments in artificial intelligence and machine learning.

Biological sex influences the life course development of blood pressure, systemic arterial hypertension, and hypertension-associated complications through neural, hormonal, renal, and epigenetic mechanisms. Sex hormones influence blood pressure regulation through interaction with several main regulatory systems, including the autonomic nervous system, the renin-angiotensin-aldosterone system, endothelin, and renal mechanisms. The modulation of vascular function by sex hormones varies over the lifespan.

Background: Aortic structural degeneration occurs with aging; however, 3-dimensional geometric remodeling has not been well characterized in large populations.
Methods: We segmented the thoracic aorta from magnetic resonance images of 56 164 UKB (UK Biobank) participants and computed tomography images of 9417 PMBB (Penn Medicine Biobank) participants. We quantified structural measurements of elongation, dilation, tortuosity, and curvature across the thoracic aorta.

We evaluated the systemic cardiovascular and carotid baroreflex support of arterial pressure during recovery from whole-body, passive heating in young and older adults. Supine mean arterial pressure (MAP), cardiac output (Q; acetylene washin), systemic vascular conductance (SVC), heart rate (HR), and stroke volume (SV) were evaluated in 16 young (8F, 18-29 years) and nine older (6F, 61-73 years) adults at normothermic baseline and for 60-min passive heating and 120-min normothermic recovery. Externally applied neck pressure was used to evaluate HR, brachial vascular conductance, and MAP responses to carotid baroreceptor unloading.

Aging is the greatest risk factor for cardiovascular diseases (CVD) and is characterized by inflammation, oxidative stress, and cellular senescence. Cellular senescence is a state of persistent cell cycle arrest triggered by stressors such as DNA damage and telomere attrition. Senescent endothelial cells (ECs) can impair vascular function and promote inflammation, thereby contributing to CVD progression.
