Influence of Albuminuria on Cardiovascular Risk in Patients With Stable Coronary Artery Disease
Bibliographic record
Abstract
BACKGROUND: Patients with chronic kidney disease are at increased risk for cardiovascular morbidity and mortality. We assessed the association between albuminuria and the risks for death and cardiovascular events among patients with stable coronary disease. METHODS AND RESULTS: We studied patients enrolled in the Prevention of Events with an ACE inhibitor (PEACE) trial, in which patients with chronic stable coronary disease and preserved systolic function were randomized to trandolapril or placebo and followed up for a median of 4.8 years. The urinary albumin to creatinine ratio (ACR) assessed in a core laboratory in 2977 patients at baseline and in 1339 patients at follow-up (mean 34 months) was related to estimated glomerular filtration rate and outcomes. The majority of patients (73%) had a baseline ACR within the normal range (<17 mug/mg for men and <25 mug/mg for women). Independent of the estimated glomerular filtration rate and other baseline covariates, a higher ACR, even within the normal range, was associated with increased risks for all-cause mortality (P<0.001) and cardiovascular death (P=0.01). The effect of trandolapril therapy on outcomes was not modified significantly by the level of albuminuria. Nevertheless, trandolapril therapy was associated with a significantly lower mean follow-up ACR (12.5 versus 14.6 mug/mg, P=0.0002), after adjustment for baseline ACR, time between collections, and other covariates. An increase in ACR over time was associated with increased risk of cardiovascular death (hazard ratio per log ACR 1.74, 95% CI 1.08 to 2.82). CONCLUSIONS: Albuminuria, even in low levels within the normal range, is an independent predictor of cardiovascular and all-cause mortality.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
