Ibuprofen claimed to raise cardiac arrest risk by a third

"Taking common painkillers like ibuprofen 'increases your risk of cardiac arrest by a THIRD'," The Sun reports.
Researchers found a link between the potentially fatal heart problem and ibuprofen use, as well as another type of non-steroidal anti-inflammatory drug (NSAID) called diclofenac.
 A cardiac arrest is a serious emergency where the heart stops pumping blood around the body.
The Danish study looked at 29,000 people who experienced a cardiac arrest, and then at whether these people had taken NSAIDs.
The researchers found the risk of a cardiac arrest was increased by a third for those who took ibuprofen in the 30 days leading up to cardiac arrest.
The risk was doubled for those taking diclofenac, which is only available on prescription in the UK. There was no evidence of an increased risk for other NSAIDs.
But the underlying biological reasons for this link weren't discussed in the study, so it's not clear what might cause this increased risk of cardiac arrest.
It's also possible some people were taking NSAIDs because they had symptoms of a pre-existing (possibly undiagnosed) condition that could increase the risk of cardiac arrest, such as heart disease.
An alternative painkiller to try is paracetamol, or you could try physiotherapy for things like joint and muscle pain. Get advice from your pharmacist or GP on the most suitable treatment for your symptoms.
