Scientists have found that a stem cell injection could repair damaged hearts in humans.
And they hope the injection could even prevent heart attacks from occurring in the first place.
The new study shows that re-injected stem cells naturally home in on damaged regions of the heart to repair them.
Heart failure — when the heart is unable to pump blood around the body adequately — affects more than 750,000 people in the UK, causing breathlessness and impeding daily activities. Current treatments are aimed at treating the underlying causes, such as coronary heart disease, heart attack and blood pressure through lifestyle changes, medicines and in severe cases, surgery. These treatments are sometimes successful in preventing or delaying heart failure. However, once heart failure develops the only curative treatment is heart transplantation.
