Daily dose of vitamin D ‘can improve function in damaged hearts’ – Telegraph.co.uk

A healthy person’s ejection fraction is usually between 60 per centĀ and 70 per cent.

Among the heart failure patients taking part in the study it averaged 26 per cent, but increased to 34 per centĀ for those taking vitamin D.

For some patients, regularly taking vitamin D might reduce the need for an implantable cardioverter defibrillator (ICD), a device that corrects abnormal heart rhythms, said the scientists whose findings were presented at an American College of Cardiology meeting in Chicago.

Heart failure, which can lead to shortness of breath and exhaustion, affects about 900,000 people in the UK and more than 23 million worldwide.

Vitamin D levels are boosted by exposing the skin to sunlight. It is often lacking in heart failure patients because they tend to be older and less likely to engage in outdoor activities.
