Silent atherosclerosis was detectable from early maturity and confirmed sex-specific patterns of progress with age, in accordance with outcomes from the REACT research introduced in a Sizzling Line session right this moment at ESC Congress 2026 and revealed concurrently within the New England Journal of Drugs.
Throughout the globe, round 20 million individuals die from heart problems (CVD) yearly and most of those deaths are as a consequence of atherosclerosis. Atherosclerosis might start in early maturity and stay clinically silent for many years earlier than manifesting primarily as a coronary heart assault, stroke or sudden cardiac demise.
Investigating the presence of silent atherosclerosis throughout the grownup lifespan was the primary purpose of the primary a part of the possible observational research, the REACT Initiative, which is led by Professor Henning Bundgaard from Rigshospitalet – Copenhagen College Hospital, Denmark and Professor Borja Ibanez from Centro Nacional de Investigaciones Cardiovasculares (CNIC), Madrid, Spain.
“At present, an individual’s threat of growing atherosclerotic CVD is estimated in accordance with their threat components, resembling age, intercourse, smoking standing, blood stress and levels of cholesterol, and this determines whether or not major prevention methods are prescribed,” defined research presenter, Professor Bundgaard. “This method depends on an estimation – not on data of the presence of the particular illness (i.e., atherosclerotic plaques) – and we could also be lacking necessary alternatives to stop cardiovascular occasions in people in whom atherosclerosis has constructed up a few years beforehand,” he famous.
In REACT, totally different imaging modalities have been used to measure silent atherosclerosis in adults with out identified CVD aged 18 to 70 years previous from Denmark and Spain in a cross-sectional research. Three-dimensional vascular ultrasound was used to evaluate atherosclerosis in carotid arteries (within the neck) and femoral arteries (within the leg); the guts arteries (coronaries) have been imaged utilizing computed tomography (CT) angiography and calcification standing.
The research included 16,808 adults who had a imply age of 45 years. Contributors have been balanced throughout age a long time in accordance with a pre-specified plan with equal proportions of ladies and men in every age decade.
The researchers discovered silent atherosclerosis in 57.1% of individuals. It was already detectable in roughly 1 in 13 individuals aged 18–29 years and was present in 9 out of 10 individuals aged 60–70 years, with prevalence rising with age in an S-shaped curve.
Atherosclerosis prevalence elevated earlier in males, whereas ladies confirmed a later and significantly steep midlife enhance, across the typical age of menopause. As well as, rising age was related to enlargement of atherosclerosis and an exponential enhance in age-related atherosclerotic plaque quantity. Most people with silent atherosclerosis of their coronary heart had atherosclerosis of their neck and/or leg arteries.
These knowledge from a number of places assist the idea of silent atherosclerosis as a systemic, progressive illness course of with males displaying an roughly 5-to-10-year earlier atherosclerotic trajectory than ladies.”

The researchers additionally examined the extent to which typical cardiovascular threat evaluation classifies individuals with silent atherosclerosis as excessive threat. They discovered that the SCORE2 threat instrument categorised solely a small minority of individuals with silent atherosclerosis as excessive threat, with a marked lack amongst youthful individuals.
Professor Bundgaard concluded: “Figuring out and treating silent atherosclerosis as early as attainable might assist scale back the worldwide burden of CVD. Our findings assist additional potential research to research whether or not imaging-guided therapy of these with early proof of illness –detected utilizing a handheld ultrasound scanner – can enhance present requirements. If profitable, this might assist a precision medication method to atherosclerotic heart problems.” Based mostly on the introduced findings, a significant randomised trial is deliberate as a part of the second section of the REACT Initiative.
