Magnesium supports heart health by regulating electrical signals that control heart rate and rhythm, while also aiding the function of heart muscles and blood vessels.

A team of researchers have discovered that a mutation in a ribosomal protein found specifically in heart and skeletal muscle leads to impaired cardiac contractility in mice. The mutation was found to ...

Researchers find that deficiency in RPL3L, a ribosome expressed in heart and skeletal muscle, impairs cardiac contractility due to delayed mRNA translation Fukuoka, Japan—A team of researchers have ...

A new study provides evidence that COVID-19 patients' heart damage is caused by the virus invading and replicating inside heart muscle cells, leading to cell death and interfering with heart muscle ...

Since early in the pandemic, COVID-19 has been associated with heart problems, including reduced ability to pump blood and abnormal heart rhythms. But it's been an open question whether these problems ...

More than 300,000 people suffer a heart attack in Germany every year. The heart muscle is then no longer supplied with sufficient blood and oxygen, and part of the tissue dies and scars. Unlike the ...
