A Danish study has shown that damage in people having a heart attack can be prevented by temporarily stopping blood flow in the arm. According to researchers, the procedure "kick-starts" natural mechanisms in the heart to counter the lack of oxygen.
In The Lancet study of around 150 patients, those who were treated this way in the ambulance on the way to hospital sustained less damage to heart tissue, reports the BBC.
