Component

Coronary heart disease

Coronary heart disease. Species, exposure and limitations are retained in each linked claim.

4 recorded relationships. Experimental role, claim status and evidence remain attached to each record.

How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What acts on it

  1. Carriers of the ADH1B rs1229984 A-allele consumed 17.2% fewer units per week, had lower systolic blood pressure, interleukin-6, waist circumference and body mass index, and had lower odds of coronary heart disease (odds ratio 0.90), with the protective association the same across all categories of alcohol consumption.

  1. A median dose of 3.5 grams per day of oat beta-glucan significantly lowered LDL-cholesterol by -0.19 with 95% CI -0.23 to -0.14 mmol/l, non-HDL-cholesterol by -0.20 with 95% CI -0.26 to -0.15 mmol/l and apoB by -0.03 with 95% CI -0.05 to -0.02 g/l compared with control interventions, and there was evidence for considerable unexplained heterogeneity in the analysis of LDL-cholesterol with I-squared of 79% and non-HDL-cholesterol with I-squared of 99%.

  2. The applicant identified a total of 22 references which included three meta-analyses and 19 randomised controlled trials as being pertinent to the health claim, in weighing the evidence the Panel took into account that most of the trials investigating the effects of oat beta-glucan at doses of at least 3 grams per day have shown a statistically significant decrease in LDL-cholesterol concentrations and that there was strong evidence supporting the biological plausibility of the effect, and the Panel concludes that a cause and effect relationship has been established between the consumption of oat beta-glucan and lowering of blood LDL-cholesterol concentrations, considering that in order to bear the claim foods should provide at least 3 grams of oat beta-glucan per day.

  3. In haemodynamic studies sildenafil produced small decreases in systemic and pulmonary blood pressure but caused no adverse cardiovascular effects in specific populations of men with coronary heart disease, and it caused no significant changes in coronary blood flow but had a positive effect on coronary flow reserve in men with severe coronary artery disease, suggesting that PDE5 may play an important role in the regulation of coronary blood flow in the healthy and diseased heart, while in retrospective analyses of extensive clinical trials treatment was not associated with any increase in cardiac risk in patients not receiving organic nitrates or nitrate donor drugs.
