The heart is the body's hardest-working muscle. Whether you're awake or asleep, or exercising or resting, your heart is always at work. It pumps blood through arteries to deliver oxygen to organs and ...

Sustainable engraftment of heart muscle cells (cardiomyocytes) can be achieved by implanting patches of engineered heart muscle onto the surface of the heart under immune suppression. Evidence from ...

A new RNA-based therapy aims to address one of cardiology’s most persistent challenges: the heart’s inability to regenerate after injury.

Researchers at the University of California, Irvine, have developed a polymeric biohybrid cardiac device that harnesses the ...

A new study from Columbia University reveals a promising RNA-based therapy that could help the heart repair itself after a ...

A new biomaterial delivered to the heart soon after a heart attack can heal damaged tissue from the inside out. Heart attacks kill cardiac muscle tissue, scarring the heart and leaving permanent ...

Coin-sized disks cut from the cocoon of the tasar silkworm grub provide a basic scaffold for heart muscle cells.Image: MPI for Heart and Lung Research Because damaged human-heart muscle cannot be ...

When someone suffers a heart attack, their heart is left permanently scarred and thus less capable of pumping blood. According to a new study, however, a protein injection could help undo such damage.

SCAD — strikes without warning and is often mistaken for something else because it usually affects relatively young, healthy women in their 40s and 50s. The symptoms are similar to a heart attack, but ...

Scientists develop a microneedle bandage for cardiac tissue regeneration using the mussel adhesive protein (MAP). Damaged cardiac wall is regenerated by delivering biofunctional peptides to the ...
