TUESDAY, July 5 (HealthDay News) -- A new study finds that painkillers widely used to treat inflammation are associated with an increased risk of atrial fibrillation, a heart rhythm disorder connected with a raised risk of stroke, heart failure and death.
Previous research has linked non-steroidal anti-inflammatory drugs (NSAIDs) and newer anti-inflammatory medications known as cox-2 inhibitors to an increased risk for heart attacks and strokes, but this is the first study to link the painkillers with atrial fibrillation.
Danish researchers looked at 32,602 patients who had a first diagnosis of atrial fibrillation between 1999 and 2008. Each of those patients was compared with 10 age and gender-matched controls from the general population in Denmark.
The results showed that use of these medications was associated with an increased risk of atrial fibrillation. The link was strongest among new users of the drugs, with a 70 percent increased risk for cox-2 inhibitors and a 40 percent increase in risk for non-selective NSAIDs.
The increased risk is equal to about seven extra cases of atrial fibrillation per 1,000 new users of cox-2 inhibitors and about four extra cases per 1,000 new users of non-selective NSAIDs, according to the researchers at Aarhus University Hospital.
They also found that the risk when starting treatment with cox-2 inhibitors seemed highest in older people and patients with chronic kidney disease or rheumatoid arthritis.
"Our study thus adds evidence that atrial fibrillation or flutter need to be added to the cardiovascular risks under consideration when prescribing NSAIDs," the researchers concluded.
"There is evidence that these medicines affected the heart, but [we] did not have evidence that it affected the rhythm of the heart. This study sheds light on another problem that we did not know with these medicines," Dr. Furqan Tejani, director of advanced cardiovascular imagin
