Risk prediction of early-onset myocardial infarction using plasma proteomics, conventional risk factors, and polygenic risk score.

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
BACKGROUND AND
objectivesEpidemiological trends indicate a concerning rise in early-onset cases of myocardial infarction (MI). We aimed to assess and compare the ability of plasma proteomics, conventional risk factors, and polygenic risk score (PRS) for the risk prediction of early-onset myocardial infarction (EOMI).
methodsIncluded were 13,097 participants aged 50 or younger, without prevalent cardiovascular diseases. The participants were randomly divided into training and validation sets. EOMI was defined as MI diagnosed before age 55. In the training set, 2,093 plasma proteins were assessed for the associations with incident EOMI using Cox proportional hazards regression models. Important proteins were selected by the least absolute shrinkage and selection operator (LASSO) regression to develop protein-based models. The predictive performance of protein-based models, conventional risk factors, and PRS, either alone or as combinations, was assessed in the validation set.
resultsTwo protein-based models were constructed using 22 key proteins selected by LASSO. Each standard-deviation increment of a weighted protein score was associated with a 2.57-fold higher risk of EOMI. Incorporating this protein score (ΔC-index = 0.125; 95% CI: 0.040, 0.213), a protein panel (ΔC-index = 0.189; 95% CI: 0.065, 0.276), or other conventional risk factors (ΔC-index = 0.158; 95% CI: 0.039, 0.239) each significantly improved the predictive performance over a basic model including age, sex, and race/ethnicity, whereas adding PRS did not. The combination of the protein panel and conventional risk factors demonstrated the best discrimination ability (C-index = 0.875; 95% CI: 0.814, 0.935).
conclusionsPlasma proteomics enhanced the risk prediction for EOMI beyond conventional risk factors and PRS. These findings may have implications for risk stratification and personalized prevention which prevent or delay the onset of myocardial infarction among relatively younger population.
