epiglucan and Coronary-Artery-Disease

There has been recent interest in barley as a therapeutic food owing to its high content of beta-glucan (β-glucan), a viscous soluble fiber recognized for its cholesterol-lowering properties. The objective of this study was to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) investigating the cholesterol-lowering potential of barley β-glucan on low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C) and apolipoprotein B (apoB) for cardiovascular disease (CVD) risk reduction.. MEDLINE, Embase, CINAHL and the Cochrane CENTRAL were searched. We included RCTs of ⩾3-week duration assessing the effect of diets enriched with barley β-glucan compared with controlled diets on LDL-C, non-HDL-C or apoB. Two independent reviewers extracted relevant data and assessed study quality and risk of bias. Data were pooled using the generic inverse-variance method with random effects models and expressed as mean differences (MDs) with 95% confidence intervals (CIs). Heterogeneity was assessed by the Cochran Q-statistic and quantified by the I. Pooled analyses show that barley β-glucan has a lowering effect on LDL-C and non-HDL-C. Inclusion of barley-containing foods may be a strategy for achieving targets in CVD risk reduction.

There is limited information about the association between oat fiber intake and future cardiovascular events in CAD patients after coronary intervention for secondary prevention. This study enrolled 716 patients after coronary intervention in clinical stable status from the CAD cohort biosignature study. Patients were analyzed according to whether the presence of regular oat fiber intake during the follow-up period, and the association with endpoints including cardiovascular death, non-fatal myocardial infarction, non-fatal stroke and revascularization procedures were analyzed. The average follow-up period is 26.75 ± 8.11 months. Patients taking oat fiber were found to have lower serum levels of LDL, triglycerides, ratio of TC/HDL, as well as lower inflammatory markers values. After adjusting for confounders in the proportional hazard Cox model, oat fiber intake was associated with a lower risk of future revascularization (HR = 0.54, 95% CI 0.35-0.85; p = 0.007), and lower risk of major adverse cardiovascular events (HR = 0.62, 95% CI 0.43-0.88; p = 0.008), suggesting the association of oat fiber use and lower risk of future adverse event in CAD patients after coronary intervention.
