Silent Artery Disease May Already Affect Adults Under 30, Study Finds

An international study suggests that around one in 13 adults aged 18 to 29 already have silent atherosclerosis, highlighting a cardiovascular risk in an age group often considered healthy.

Atherosclerosis develops when fatty deposits, known as plaque, build up inside arteries. Over time, this buildup can narrow blood vessels and restrict blood flow.

The condition is described as “silent” because it may develop without noticeable symptoms. Feeling well does not necessarily mean that arteries are free of disease.

Atherosclerosis can increase the risk of serious cardiovascular problems, including heart attacks and strokes. The finding does not mean that every young adult with early artery changes faces an immediate cardiac emergency.

The summary did not provide details about the study’s participants, screening methods or locations. Those details would be needed to assess how broadly the estimate applies to young adults.
