Silent Atherosclerosis Found in Young Adults
2 Oct
Summary
- Plaque buildup detected in 1 in 13 adults aged 18-29.
- Cardiovascular disease process can begin in childhood.
- Early detection and risk factor control are crucial.
A study published in The New England Journal of Medicine has revealed a concerning trend: silent atherosclerosis, characterized by plaque buildup in arteries, is detectable in about 8.7% of men and 6.7% of women aged 18 to 29. This indicates that the underlying processes of cardiovascular disease can commence in young adulthood, long before symptoms appear. The study examined over 16,000 adults, finding plaque in over half of participants aged 18 to 70.
The gradual development of atherosclerosis means that arteries can accommodate changes without immediate impact on blood flow. However, this silent phase poses a significant risk, as plaques can rupture and lead to heart attacks or strokes. Experts stress that identifying and managing risk factors such as high cholesterol, blood pressure, and family history from a young age is key to altering the lifetime trajectory of heart health.
This early onset is particularly relevant for South Asian populations, who have a predisposition to earlier cardiometabolic diseases. Factors like genetics, body composition, diet, and lifestyle contribute to this increased risk. While routine artery imaging for all young people is not recommended, maintaining a healthy lifestyle—including a balanced diet, regular exercise, and avoiding tobacco—remains the foundation for cardiovascular prevention throughout life.
