Distinct clinical profiles and outcomes in young versus older adults with acute coronary syndrome: a comparative cohort study.
Article in Journal of cardiothoracic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAcute coronary syndrome (ACS) in young adults (≤ 40 years) exhibits distinct characteristics compared with older populations, yet detailed comparative data in Chinese cohorts remain limited.
methodsThis comparative retrospective cohort study analyzed 112 consecutive ACS patients aged ≤ 40 years (Young Group) and 112 matched non-young ACS patients (age > 40 years, Non-Young Group) undergoing coronary angiography at a tertiary center between September 2018 and November 2024. We evaluated clinical profiles, angiographic features, revascularization strategies, and 12-month major adverse cardiac events (MACE).
resultsCompared with the Non-Young Group, young patients exhibited a higher male predominance (p < 0.001) and a lifestyle related risk profile characterized by significantly higher rates of current smoking (p < 0.001) and obesity (p < 0.001). Young patients more frequently presented with STEMI (p = 0.009) and single vessel disease (p = 0.011), with thrombotic lesions being the dominant etiology (p = 0.005). Regarding treatment, the Young Group had a significantly higher utilization of drug coated balloons (p < 0.001) and lower stent implantation rates (p < 0.001). At 12 months, the MACE rate was significantly lower in the Young Group (p = 0.038). Within the young cohort, multivessel disease (aHR 2.89), LVEF < 50% (aHR 3.25), and stent non-implantation (aHR 2.30) were independent MACE predictors. Clustering of ≥ 2 key modifiable risk factors (dyslipidemia, obesity, smoking) conferred a 3 to 5 fold higher MACE risk in young adults (p < 0.001).
conclusionsYoung ACS patients possess a distinct clinical and angiographic profile characterized by a higher thrombotic burden and lifestyle related risk factors compared with older patients. While they exhibit more favorable short term survival and respond well to stent-less revascularization strategies, their long term prognosis is heavily dependent on the aggressive modification of synergistic modifiable risk factors.
