Cardiovascular benefits of probiotics: a review of experimental and clinical studies
Bibliographic record
Abstract
The microbiota inhabiting the human gastro-intestinal tract is reported to have a significant impact on the health of an individual. Recent findings suggest that the microbial imbalance of the gut may play a role in pathogenesis of cardiovascular diseases (CVD). Therefore, several studies have delved into the aspect of altering gut microbiota with probiotics as an approach to prevent and/or treat CVD. The World Health Organization defines probiotics as live microorganisms that, when consumed in adequate amounts, have a positive influence on the individual's health. The present review focuses on strategies of human dietary intervention with probiotic strains and their impact on cardiovascular risk factors like hypercholesterolemia, hypertension, obesity and type-2 diabetes. Accumulating evidence shows probiotics to lower low density lipoproteins (LDL)-cholesterol and improve the LDL/high density lipoproteins (HDL) ratio, as well as lower blood pressure, inflammatory mediators, blood glucose levels and body mass index. Thus, probiotics have the scope to be developed as dietary supplements with potential cardiovascular health benefits. However, there is not only ambiguity regarding the exact strains and dosages of the probiotics that will bring about positive health effects, but also factors like immunity and genetics of the individual that might influence the efficacy of probiotics. Therefore, further studies are required not only to understand the mechanisms by which probiotics may beneficially affect the cardiovascular system, but also to rule out any of their probable negative effects on health. The present review aims to critically appraise the complexity of the available data with regard to the cardiovascular benefits of probiotics.

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.
