Damage from heart attacks is permanent, at least for now--but at least for now. But researchers are hoping to fix that by coaxing stem cells to turn into heart muscle cells that can essentially repair ...

Unlike humans, zebrafish can completely regenerate their hearts after injury. They owe this ability to the interaction between their nervous and immune systems, as researchers led by Suphansa ...

Every year, more than 200,000 people in Germany suffer a heart attack. This is caused by blocked coronary arteries. As a result, part of the heart muscle is no longer supplied with sufficient blood ...

* Discovery of macrophages guiding scar tissue control after heart attack * New insights pave the way for advanced heart //regeneration therapies Over the course of evolution, the human heart has lost ...

Owen Monroe was 18 days old when he made history, becoming the first person in the world to receive a partial heart transplant. His groundbreaking surgery, performed in 2022, even captured the ...

WASHINGTON -- One of medicine's greatest triumphs is hitting a snag: Up to 1 million people born with once-lethal heart defects now have grown up, a pioneering generation largely unaware that heart ...

A team of scientists from Harvard Medical School and Duke University has created a new kind of tissue that can change heart activity using only light—no wires, no surgery, no harm. This groundbreaking ...

Researchers at Hannover Medical School have gained new insights into the cytokine meteorin-like (METRNL) and its role in promoting heart repair after myocardial infarction. The team showed that in ...

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

Scientists have engineered dual-membrane nanoparticles that home in on heart tissue after a heart attack, delivering regenerative molecules while evading the body’s immune defences. Image Credit: tong ...

Immune response and the lymphatic system are central to cardiac repair after a heart attack, according to a new study. These insights into the basic mechanisms of cardiac repair are the first step ...
