Aortic calcification links metabolic and inflammatory damage to increased CV mortality and neurocognitive decline.
Why the study?
Much understanding of the causes, characterization, and consequences of aortic calcium deposition has emerged only within the past decade, motivating a review of recent clinical and discovery science advances.
This review highlights recent advances in understanding the biology of calcific aortopathy, including innate immunity, senescence, and osteogenic mechanisms, pointing toward future medical treatments.

“We are starting to appreciate that CAVS is not simply a passive degenerative process associated with aging but that it involves active mechanisms that may be amenable to intervention.”
“Our blood is saturated with calcium and phosphate. Calcification of collagen and growth of nodules is inevitable given our blood chemistry, biology and composition. However, the silver lining to all of this is that we also found that our body has evolved these incredibly intricate and effective processes to fight mineralization. It can't stop it, but it can slow it down dramatically.”
“This hardening, or biomineralisation, is essential for the production of bone, but in arteries it underlies a lot of cardiovascular disease and other diseases associated with ageing like dementia.”
Shifts aortic calcification to active modifiable disease; extends research into innate immunity, senescence, and osteogenesis for future therapies.
The arterial vasculature is the second most frequently calcified structure in the human body after the skeleton.Calcification of the aorta and aortic valves occurs in most individuals in westernized societies with advancing age, with abdominal aortic calcification generally preceding ascending thoracic aortic disease.In cardiac valves and the thoracic aorta, however, calcification often arises earlier in common disease contexts characterized by metabolic, mechanical, or inflammatory injury (eg, metabolic syndrome, chronic kidney disease, irradiation).In these settings, calcification frequently involves the arterial media as a histoanatomic feature, and is associated with accelerated neurocognitive decline and increased cardiovascular mortality, reflecting a form of precocious aging.The term arteriosclerosis was coined nearly 2 centuries ago to describe the calcium-mediated hardening of the aorta and conduit arteries observed at autopsy with aging.However, much of our understanding of the causes, characterization, and consequences of aortic calcium deposition has emerged only within the past decade.Features of disease biology, including engagement of innate immunity, senescence (inflammaging), and ectopic activation of osteogenic mechanisms, are consistently revealed.In this article, we briefly review the burgeoning literature, highlighting recent advances in clinical and discovery science with translational implications.Given the current trajectory, after 2 centuries of disease recognition, the next decade of innovation promises meaningful progress toward effective medical treatments to prevent and treat the clinical consequences of calcific aortopathy.

Towler et al. (2026) conducted a review in Calcific aortopathy. Recent advances in the study of calcific aortopathy reveal the involvement of innate immunity, senescence, and osteogenic mechanisms in response to aging and injury.
