Heart Disease

The human heart lacks the ability to replenish cells. But now, researchers at the University of Texas Southwestern have uncovered a suite of proteins in mice that could be switched off to induce heart cells to begin replicating again temporarily.

Heart cells don’t naturally replenish, so after a heart attack it stays permanently damaged. Cambridge researchers have now stumbled onto genes that appear to trigger heart cell regeneration – and they did so by accident, while researching cancer.

It was just last year when a study concluded that a warm bath before bed should indeed help you to sleep. Now, a new study suggests that regular hot soaks may also lower the risk of death from cardiovascular disease.

Triglycerides are a form of fat that circulates through the bloodstream, and high levels can lead to obesity and related illnesses. Now, researchers have found a way to efficiently produce a protein that clears these fats from the bloodstream.

A newly published study from researchers at Brigham and Women’s Hospital in Boston is suggesting irregular sleep patterns, such as inconsistent bedtimes from day to day, can potentially double a person’s risk of developing cardiovascular disease.

Two new systematic reviews have concluded omega-3 supplements confer little protective benefit against either cardiovascular disease or cancer. The research builds on prior study suggesting fish oil is mostly useless if taken by healthy individuals.

A new study has found a plaque-identifying toothpaste can potentially lower levels of systemic inflammation – which has been linked to cardiovascular disease, stroke and hypertension – by improving a person’s brushing efficacy.

Two new studies are offering insights into diet, gut bacteria, and health. One finds a Mediterranean diet can reconfigure gut bacteria to promote healthy aging, while another finds gut bacteria producing a metabolite that increases heart disease risk.

Atherosclerosis is a disease where fatty plaques build up in the arteries, increasing risk of heart attack or stroke. But now, researchers at Oxford have found a protein that could be targeted in new prevention drugs for these deadly buildups.

A study is suggesting alterations to a dairy cow’s diet can result in milk lower in saturated fat and a clinical trial in humans demonstrates these natural “healthier” dairy products may lead to positive heart health effects.

A Phase 3 clinical trial into the efficacy of a fish-oil-derived drug called Epanova has been discontinued. The trial was designed to establish the use of the drug, a formulation of two omega-3 fatty acids, as an adjunct to statins for heart disease.

A large study out of China has found drinking green tea at least three times a week can be linked to longer lifespan and lower rates of heart disease and stroke. The same association was not seen in black tea drinkers.
