Elevated heart rate tied to a greater risk of dementia

Older adults with a high resting heart rate may face an increased risk of dementia, according to new findings published in Alzheimer’s & Dementia.

The study included data from more than 2,100 participants who were 60 years old and older. All participants lived in Stockholm, Sweden, and they were followed for up to 12 years.

Overall, participants with a resting heart rate of 80 bpm or higher were found to have a 55% higher risk of dementia than those who had a resting heart rate of 60 to 69 bpm. The association remained even after making adjustments for different factors, including cardiovascular health.

The study’s authors emphasized that they could not establish a causal relationship between resting heart rate and dementia, but they did say their findings could potentially help patients receive the care they need much earlier in life.

“We believe it would be valuable to explore if resting heart rate could identify patients with high dementia risk,” lead author Yume Imahori, a researcher at the Karolinska Institutet in Sweden, said in a prepared statement. “If we follow such patients’ cognitive function carefully and intervene early, the onset of dementia might be delayed, which can have a substantial impact on their quality of life.”

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
