Many patients given beta blockers after a heart attack may not benefit from being on the drugs, suggesting they may be being over-prescribed, researchers said.

UK medical guidelines recommend all people who have had a heart attack should be put on beta blockers, which are medicines that reduce the activity of the heart and lower blood pressure.
