Abstract

fetched live from OpenAlex

AIMS: The aim was to describe outcomes among patients with stable coronary artery disease (CAD) with or without a history of myocardial revascularization in a large contemporary cohort. METHODS AND RESULTS: Patients with stable CAD were selected from the Reduction of Atherothrombosis for Continued Health (REACH) registry. The cohort was divided into patients with ( n = 25 583) and without ( n = 13 133) a history of myocardial revascularization. Crude outcomes were described according to the use and type of revascularization: percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG). The primary outcome was cardiovascular (CV) death. At baseline, the non-revascularized group was older and had more CV risk factors. At 36-month median follow-up, previous revascularization was associated with a lower risk of CV death [crude incidence rate (CIR): 6.82 vs. 9.08%, hazard ratio (HR) 0.73 [95% confidence interval (CI) 0.66-0.80]; P < 0.01]. This association was seen for patients with a history of PCI (CIR 5.78 vs. 8.88%, HR 0.64 [0.58-0.71]; P ≤ 0.01), but not with CABG (HR 1.26 [1.14-1.49]; P < 0.01), and was consistent regardless of prior MI and the timing of prior revascularization. CONCLUSION: Among patients with stable CAD, a history of myocardial revascularization was associated with lower CV mortality, particularly when PCI was the mode of revascularization. Coronary artery disease patients managed non-invasively represent a high-risk group.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
