Viagra might help muscular dystrophy patients

Researchers say the drug seems to ward of heart failure in patients with MD.

Muscular dystrophy is genetic condition causing wasting of the muscles. That means it also weakens the muscles which keep the heart pumping strongly.

Viagra prevents the loss of a molecule that helps keep blood vessels dilated. This ensures the heart receives a proper supply of blood and remains healthy and strong.

Researchers say keeping the heart strong helps it withstand the impact of weakened muscles.

There's more on this study in The Proceedings of the National Academy of Sciences.
