Hidden Artery Plaque Detected in 1 in 13 Adults Under 30
Advanced imaging of 16,808 adults found artery plaque in 57.1% with no known heart disease, and in about 1 in 13 people under 30, far earlier than routine screening typically catches.

In brief
- 57.1% of 16,808 adults with no known cardiovascular disease showed artery plaque on advanced scans
- About 1 in 13 adults under 30 — roughly 7.7% — had hidden plaque on imaging
- The international study used advanced imaging rather than standard blood pressure and cholesterol checks
- Routine cardiovascular risk assessments do not directly visualize plaque in artery walls
- The study is observational and cannot prove that treating silent plaques prevents future heart attacks
In an international scan study covering 16,808 adults, researchers found silent plaque buildup in the arteries of roughly 1 in 13 people younger than 30 — a rate far higher than standard cardiovascular risk screens predict.
The finding, reported using advanced imaging on adults with no known heart disease, showed plaque in 57.1% of participants across all age groups. That number challenges the long-standing assumption that atherosclerosis is primarily a problem of middle and old age.
What did the scans actually look for?
The study used advanced imaging to detect atherosclerotic plaque in artery walls. Atherosclerosis is the slow buildup of fatty deposits, cholesterol, calcium, and other material on the inner lining of arteries. Over time, these deposits harden and narrow the vessels. A ruptured plaque can trigger a blood clot, causing a heart attack or stroke.
Most participants had no prior diagnosis of cardiovascular disease, meaning routine clinical exams had not flagged them as at risk.
How common was plaque in younger adults?
Among adults under 30, roughly 7.7% — about 1 in 13 — showed hidden plaque on imaging. The result points to a far earlier onset of a condition typically associated with later life.
The finding suggests atherosclerosis can take root decades before symptoms appear. By the time chest pain or other warning signs emerge, artery walls may already carry years of silent damage.
Why do standard checkups miss it?
Routine cardiovascular risk assessments rely on blood pressure readings, cholesterol panels, age, smoking status, and lifestyle questionnaires. These tools estimate the probability of a future event but cannot directly see what is already lodged in artery walls.
Imaging techniques such as CT angiography or carotid ultrasound can visualize plaque directly. Yet these scans are not part of standard screening guidelines for young adults who feel healthy and show no symptoms.
What does this mean for screening?
The authors argue that silent atherosclerosis is far more common than symptoms or routine risk scores suggest. Detecting plaque early could, in theory, allow clinicians to prescribe statins, blood pressure medication, or targeted lifestyle changes before a heart attack occurs.
Whether broad screening of all young adults would save more lives than it costs remains an open question. Imaging carries radiation exposure, the risk of false positives, and downstream costs from follow-up testing and patient anxiety.
What are the study's limits?
The source describes an international observational study. Observational designs can show association but cannot prove that treating these silent plaques would prevent future cardiovascular events. The 16,808 participants came from multiple countries, but the report does not specify how representative that sample is of the global population.
Researchers note that further work is needed to confirm whether early imaging changes outcomes, and which subgroups benefit most from earlier screening.
Key numbers at a glance
- 16,808 adults scanned internationally
- 57.1% of participants with no known cardiovascular disease showed plaque
- About 1 in 13 adults under 30 (roughly 7.7%) had hidden plaque
The bottom line: artery disease can begin silently in young adulthood, and the tools used to catch it today are mostly designed for people already considered at risk.
