Coronary artery calcium in a 20-year-old South Asian patient - pushing the limits of detecting "early disease".
Article in American journal of preventive cardiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Coronary artery calcium (CAC) assessment has long been reserved for intermediate-risk individuals in mid- to older-adult populations. However, a growing body of evidence supports expanding CAC measurement to younger adults who exhibit multiple risk factors or other risk-enhancing features. We describe a case of a very young, 20-year-old, South Asian man with a CAC score of 15.7 Agatston Units. Despite his age and lack of overt symptoms, his CAC score placed him at the 99th percentile for his age and sex, underscoring the limitations of relying solely on traditional risk algorithms. Early CAC detection in such patients has potential for significant clinical impact, allowing timely implementation of intensive lifestyle modification and the most aggressive possible pharmacotherapy for cardiovascular risk reduction. Evidence indicates that even minimal CAC in very young individuals can progress exponentially, markedly increasing the risk of future atherosclerotic cardiovascular disease. Nonetheless, current guidelines do not recommend CAC testing in this population, creating a missed opportunity to detect and intervene in high-risk individuals during early adulthood. These observations underscore the need for more precise risk stratification strategies in select high-risk populations. Incorporating CAC measurements into care for young, high-risk individuals-alongside newer tools such as polygenic risk scores and low-radiation coronary CT angiography-could revolutionize preventive cardiology. Further research is needed to refine the cost-effectiveness and implementation strategies for early CAC measurement, develop more inclusive guidelines, and ensure a specialized workforce capable of delivering comprehensive preventive care.
