TORONTO, Sept. 30 (UPI) -- Canadian researchers have linked a common treatment for dementia with a higher risk of hospitalization related to the heart.
Laura Park-Wyllie and colleagues at St. Michael's Hospital in Toronto looked at the health records of more than 1.4 million older adults in Ontario.
The study, published in PLoS Medicine, showed initiation of cholinesterase inhibitor therapy -- a common treatment for dementia -- was associated with a more than doubling of the risk of hospitalization for bradycardia -- a slower than normal heart rate of fewer than 60 beats per minute.
An implanted pacemaker and other treatments are used to correct bradycardia and help the heart maintain an appropriate rate.
