Ibuprofen and other painkillers may trigger a heart condition which affects almost a million Britons, a major study has shown.
Patients who regularly take the pills are up to 20 per cent more likely to develop heart failure.
Long-term use of the medication causes chemical reactions in the body which place extra strain on the heart, research suggests.
This can lead to heart failure in patients who have a history of previous heart attacks or high blood pressure. An estimated 900,000 adults in Britain have heart failure which occurs when the muscle becomes too weak to pump blood around the body.
