Recent research indicates that atherosclerosis—the buildup of fat and cholesterol in arteries—often begins much earlier than previously assumed. A major 2026 international study of over 16,800 healthy adults revealed that approximately 1 in 13 individuals aged 18 to 29 already possess detectable arterial plaque ^{[11] [12] [13]}.

Silent Progression

Atherosclerosis typically develops without symptoms for decades ^{[14] [15]}. Traditional risk calculators, which estimate probability based on cholesterol or blood pressure, often fail to identify these early-stage, "silent" plaques in younger populations ^{[3] [5] [7]}.

Why Early Detection Matters

• Shift in Screening: Experts are exploring portable ultrasound to identify plaque before it impacts the heart, moving beyond mere estimations to direct imaging ^{[3] [12] [14]}.
• Gender Disparities: Research shows that atherosclerosis progression often accelerates 5 to 10 years earlier in men than in women, with women experiencing a sharp increase post-menopause ^[13].
• Systemic Nature: Evidence suggests plaque often manifests in carotid (neck) or femoral (leg) arteries before appearing in coronary (heart) arteries ^[15].

While these findings do not imply inevitable heart failure, they highlight that cardiovascular health monitoring should begin well before middle age ^{[7] [13] [14]}.
