Group IIA Secretory Phospholipase A <sub>2</sub> , Vascular Inflammation, and Incident Cardiovascular Disease
Bibliographic record
Abstract
Objective— Inflammation is a causal risk factor for cardiovascular disease (CVD). sPLA 2 -IIA (group IIA secretory phospholipase A 2 ) plays an integral role in regulating vascular inflammation. Although studies investigated sPLA 2 -IIA in secondary prevention, we prospectively evaluated sPLA 2 -IIA mass and genetic variants with CVD events in a primary prevention population with chronic inflammation. Approach and Results— The JUPITER trial (Justification for the Use of Statins in Prevention: An Intervention Trial Evaluating Rosuvastatin) randomized participants with LDL (low-density lipoprotein) <130 mg/dL and hsCRP (high-sensitivity C-reactive protein) ≥2 mg/L to high-intensity rosuvastatin versus placebo. Baseline and 1-year plasma sPLA 2 -IIA mass was measured (N=11 269 baseline; N=9620 1 year). We also identified genetic variants influencing sPLA 2 -IIA using genome-wide association and examined them with CVD. Three hundred thirteen incident CVD events occurred during follow-up. Baseline sPLA 2 -IIA mass (median, 25th–75th percentile: 3.81, 2.49–6.03 ng/mL) was associated with increased risk of CVD: risk factor–adjusted hazard ratio (95% CI; P ) per SD increment: 1.22 (1.08–1.38; P =0.002). This remained significant (1.18; 1.04–1.35; P =0.01) after incrementally adjusting for hsCRP. Similar estimates were observed in rosuvastatin and placebo groups ( P treatment interaction>0.05). The rs11573156C variant in PLA2G2A (encoding sPLA 2 -IIA) had the strongest effect on sPLA 2 -II: median (25th–75th percentile, ng/mL) for CC and GG genotypes: 2.79 (1.97–4.01) and 7.38 (5.38–10.19), respectively; and had nonsignificant trend for higher CVD risk (hazard ratio, 1.11; 95% CI, 0.89–1.38; P =0.34). Conclusions— In the JUPITER population recruited on chronic inflammation, sPLA 2 -IIA mass was associated with CVD risk relating to vascular inflammation not fully reflected by hsCRP. Additional studies, including larger functional genetic and clinical studies, are needed to determine whether sPLA 2 -IIA may be a potential pharmacological target for primary prevention of CVD.

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.
