Heart Disease

A new algorithm has been developed to detect coronary artery disease solely from patient facial photos. The algorithm needs more refinement but experts suggest there are ethical considerations to resolve before a system like this can be deployed.

Scientists have created the first-ever functional miniature human hearts in the lab. Grown from stem cells, these heart “organoids” are made up of all primary heart cell types, and could help build better models for treating disease.

A pair of new studies highlight the potential for long-term heart complications in recovered COVID-19 patients. The research suggests the virus can damage cardiovascular muscles with inflammation detectable months after recovery, even in mild cases.

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.
