Cardiovascular Health Indicators in Aging Populations
Summary
Aging is accompanied by complex alterations in vascular structure and function, reflected in a range of clinical and biological indicators. Structural measures such as carotid intima-media thickness and plaque burden track progression of atherosclerosis, while functional assays of endothelial health and arterial stiffness signal early impairments. Circulating biomarkers, notably CD34-positive progenitor cells, reveal the capacity for endothelial repair and angiogenesis. Anthropometric changes, in particular height loss, serve as integrative markers of microvascular integrity. Serum proteins, including the anti-aging factor klotho, alongside standard metrics of cardiovascular health, offer further insight into the interplay between lifestyle, genetic predisposition and tissue resilience. Together, these indicators inform risk stratification, guide preventive strategies and underscore the global challenge of maintaining cardiovascular well-being in older adults.
Research from Nature Portfolio
Recent studies have deepened understanding of how endothelial repair dynamics influence vascular ageing. A 2024 analysis of individuals aged 60–89 demonstrated that those with carotid atherosclerosis experienced more rapid height loss, suggesting stature diminution as a non-invasive index of microcirculatory decline. Two cohort investigations in Japanese men aged 60–69 further linked circulating CD34-positive cell counts to divergent vascular outcomes. One prospective study showed that higher CD34-positive levels predict active arterial wall thickening in non-hypertensive subjects, whereas lower counts associate with impaired microvascular maintenance. A complementary follow-up emphasised that individuals with fewer CD34-positive cells are more prone to height loss over two years, implicating stem-cell scarcity in microvascular deterioration. A wider synthesis of these epidemiological findings has proposed a dual model whereby vigorous endothelial repair drives both functional and structural markers of atherosclerosis, while deficient repair leads to hypertension without overt arterial thickening.

The graph below shows the total number of articles in cardiovascular health indicators in aging populations across all publications each year (not limited to Nature Index journals).
Technical terms
Carotid intima-media thickness (CIMT): Ultrasonographic measure of arterial wall thickness used as a surrogate marker for structural atherosclerosis.
CD34-positive cells: Circulating haematopoietic stem and progenitor cells that contribute to endothelial repair and angiogenesis.
Endothelial repair: Biological process by which vascular integrity is restored through recruitment of progenitor cells and remodelling of the vessel lining.
Atherosclerosis: Chronic disease characterised by lipid-laden plaque formation within arterial walls, leading to stenosis and ischaemic events.
Life’s Essential 8: Composite metrics defined by the American Heart Association encompassing behavioural and health factors to assess overall cardiovascular health.
Klotho: Circulating protein with anti-aging properties that modulates vascular function and mineral metabolism.
Forced vital capacity (FVC): Maximum volume of air exhaled after full inspiration, serving as an indicator of pulmonary function linked to cardiovascular outcomes.
