Study heralds new heart treatment
Scientists believe they may have discovered a promising new way to treat heart disease in the future.
A study in rats suggests tiny protein fibres may be used to cut heart attack damage by stopping key cells, called cardiomyocytes, from dying.
A Harvard Medical School study showed injecting tiny fibres laced with a protective chemical into heart muscles kept the rats' organs working normally.
The study is published online by the Journal of Clinical Investigation.
