The degree of hair graying in male gender as an independent risk factor for coronary artery disease, a prospective study

Grey hair has been linked with an increased risk of heart disease in men, in research presented today at EuroPrevent 2017. “Ageing is an unavoidable coronary risk factor and is associated with dermatological signs that could signal increased risk,” said Dr Irini Samuel, a cardiologist at Cairo University, Egypt. Atherosclerosis and hair greying share similar mechanisms such as impaired DNA repair, oxidative stress, inflammation, hormonal changes and senescence of functional cells. This study assessed the prevalence of grey hair in patients with coronary artery disease and whether it was an independent risk marker of disease.

This was a prospective, observational study wh...

Defensins, anti-microbial molecules essential to maintain healthy gut flora

Extra vitamin D can restore good bacteria in the gut, according to a study in mice, giving hope in the fight against risk factors for diabetes and heart disease. It is well known that a diet high in fat can trigger a metabolic syndrome, a group of symptoms that pose as risk factors for diabetes and heart disease. Scientists have now found vitamin D deficiency is necessary for this syndrome to progress in mice, with disturbances in gut bacteria.

If these findings can be validated in humans, sun bathing and vitamin D supplements may be feasible and affordable approaches to improve or even prevent metabolic syndrome...

Reductions in Atherogenic Lipids and Major Cardiovascular Events A Pooled Analysis of 10 ODYSSEY Trials Comparing Alirocumab With Control Credit: Imperial College London

Although previous studies have suggested lowering cholesterol levels may be associated with a lower risk of heart attack, recent evidence has questioned whether very low levels are beneficial.
In the latest study, led by scientists at Imperial College London, researchers analysed data from over 5,000 people taking part in cholesterol-lowering trials. These studies utilised a new therapy to reduce cholesterol to much lower levels than previously possible.

The scientists found that dropping cholesterol to the lowest level possible – to levels similar to those we were born with – reduced the risk of heart attack, stroke or fa...

Image: Carnitine, Choline, Cancer and Cholesterol: The TMAO Connection and how Resveratrol could be anti-atherosclerotic . NB. The concentration of TMAO in blood increases after consuming foods containing carnitine or lecithin if the bacteria that convert those substances to TMAO are present in the gut. High concentrations of carnitine are found in red meat, some energy drinks, and some dietary supplements; lecithin is found in soy, eggs, as an ingredient in processed food and is sold as a dietary supplement.

Resveratrol, found in red wine etc reduces the risk of heart disease by changing the gut microbiome, according to a new study by researchers from China...
