Heart Disease

New research has discovered a distinct circadian mechanism within heart cells that influences how cardiac activity shifts across 24-hour periods. The findings offer clues to why shift workers are at higher risk of heart problems.

A team of scientists in the US investigating the relationship between metabolic syndrome and a key hormone have demonstrated how a promising new drug could play an important preventative role in a variety of conditions, including obesity and diabetes.

Cardiovascular diseases are the leading cause of death worldwide, but numbers could be reduced with better early warning systems. A new study has outlined just such a system, using nanoparticles that make atherosclerotic plaques emit ultrasound waves.

New research has revealed a microbial mechanism connecting obesity with heart disease. The study describes how a high-fat diet damages intestinal cells, leading to more bad bacteria that produce metabolites known to contribute to cardiovascular disease.

A study is offering the most detailed investigation to date into the relationship between breast cancer survival and statins – common cholesterol-lowering drugs. The study saw a 58 percent greater survival rate in breast cancer patients taking statins.

Scientists at Oxford have uncovered a mechanism behind why people with diabetes have an increased risk of cardiovascular diseases. High blood sugar levels seem to “reprogram” stem cells so that the immune cells they produce become more inflammatory.

Does it contain EPA or DHA? A new meta-analysis of 38 randomized controlled trials is suggesting the key to beneficial cardiovascular outcomes from omega-3 supplements could come down to the specific kind of fatty acid being consumed.

Accumulation of fat around the heart has long been linked to cardiovascular and metabolic disease but until now there hasn’t been a simple way to measure this. A new AI tool has been developed that can quantify these fat deposits from regular MRI images.

The heart has a limited capacity to heal itself, so heart attack survivors often have further episodes. Now, scientists have grown heart cells from stem cells, embedded them onto microspheres and injected them into damaged hearts to help repair them.

Introducing the concept of “microbiome architectures”, a new study has detected robust associations between several human diseases, including diabetes and liver cirrhosis, and patterns of bacterial genes.

Two new studies investigating the relationship between fasting and the microbiome are offering fresh insights into the way our gut bacteria composition can be remodeled by short-term dietary alterations, and how this can benefit cardiovascular health.

A robust new study has demonstrated how SARS-CoV-2, the coronavirus that causes COVID-19, can infect and directly damage heart tissue, suggesting heart damage in patients is not due to inflammation but the virus itself interfering with heart muscles.
