Cardiovascular Disease Is Related to Hypertension in Patients with Rheumatoid Arthritis: A Greek Cohort Study
Bibliographic record
Abstract
OBJECTIVE: To evaluate the incidence of cardiovascular disease (CVD) among Greek patients with rheumatoid arthritis (RA) under medical followup, and to assess the contribution of traditional CVD and RA-specific factors associated with CVD development. METHODS: This is a historic cohort study; information was collected from medical records of patients who had > 2 years' followup. Sociodemographic, clinical, laboratory, and therapeutic variables were evaluated for association with development of CVD. RESULTS: A total of 325 RA patients were studied: 250 women, mean age at RA onset 44 ± 15 years, and 75 men, mean age at RA onset 51 ± 15 years; median followup was 10 years. Fourteen women (5.6%) and 12 men (16%) developed CVD (p = 0.004). Multi-adjusted analysis revealed that hypertension (hazard ratio 3.76, 95% CI 0.99-15.06) was associated with incidence of CVD; late age at disease onset (HR 1.07, 95% CI 1.04-1.11), elevated C-reactive protein (CRP) level 1 year after start of followup (HR 1.03, 95% CI 1.00-1.05), and leflunomide treatment (HR per 1 year of treatment = 1.02, 95% CI 1.00-1.05) were also positively associated with CVD development. CONCLUSION: Hypertension was an important risk factor for CVD development in patients with RA. Late RA onset and inadequate early control of disease activity (as attested by CRP) remain additional risk factors. Leflunomide treatment may have a contributing effect. Early and effective treatment of RA and strict control of hypertension may modify the burden of CVD in RA patients.

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.
