Vitamin D Helps A Diseased Heart

A trial on 163 heart failure patients found that supplements of the vitamin, which is made in the skin when exposed to sunlight, Vitamin D, improved their hearts' ability to pump blood around the body.

The Leeds Teaching Hospitals team, who presented at a meeting of the American College of Cardiology, described the results as "stunning".

Patients were given either a 100 microgram vitamin D tablet or a sugar pill placebo each day for a year.

Researchers measured the impact on heart failure - a condition in which the heart becomes too weak to pump blood properly.

The key measure was the ejection fraction, the amount of blood pumped out of the chambers of the heart with each beat.

In a healthy adult the figure is between 60% and 70%, but only a quarter of the blood in the heart was being successfully pumped out in the heart failure patients.

But in those taking the vitamin pills, the ejection fraction increased from 26% to 34%.

Dr Witte told the BBC News website: "It's quite a big deal, that's as big as you'd expect from other more expensive treatments that we use, it's a stunning effect."

The study also showed the patients hearts became smaller - a suggestion they are becoming more powerful and efficient.
