Lipoprotein-Associated Phospholipase A2: How Effective as a Risk Marker of Cardiovascular Disease and as a Therapeutic Target?
Bibliographic record
Abstract
Lipoprotein-associated phospholipase A2 (Lp-PLA2) has been studied extensively in terms of biology, pathophysiology, diagnostic and prognostic values. Lp-PLA2 is an enzyme produced in atherosclerotic plaque by inflammatory cells, linked to LDL, HDL and VLDL. The binding of Lp-PLA2 to a specific lipoprotein fraction renders it more atherogenic. Increasing evidence has demonstrated Lp-PLA2 as a novel "ideal" marker for CVD as of its high specificity for vascular inflammation and low biologic variability. Thus, determination of Lp-PLA2 in individuals may provide clinically relevant information about their future risk of CVD events. In addition, Lp-PLA2 has been considered as a therapeutic target, which has been acted upon indirectly (lipid lowering medications) and directly (Lp-PLA2 antagonists such as darapladib) in pharmacologic therapies. This review will provide an overview on biochemistry, biology, proatherogenic, proinflammatory and proapoptotic effects of Lp-PLA2. Clinical utility and its validity as an independent CVD biomarker as well as a diagnostic biomarker to be detected in the very early stages of atherosclerosis will be also discussed. Moreover, the role of Lp-PLA2 as a pharmacologic therapeutic target is another theme of this review.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
