If you have atrial fibrillation, have another cup of coffee. In fact, have five.
“It is known that regular coffee consumption benefits cognitive performance among healthy people. The most frequent cardiac arrhythmia, atrial fibrillation, is known to independently increase the risk of dementia,” said Massimo Barbagallo, M.D., lead author of the study and a resident in the neuro intensive care unit at the University Hospital Zürich. “Thus, the question is whether coffee might offset the increased risk of cognitive impairment in people with AFib.”
“Many myths are around, but our study found no reason to discourage or forbid a patient with AFib from drinking coffee. Instead, say, ‘Enjoy, it may even be good for you!’” said Jürg H. Beer, M.D., senior author of the study and professor of medicine and hematology at the University of Zürich in Switzerland.
The study found:
- Overall, higher cognitive test scores were associated with higher coffee consumption.
- Specifically, scores for processing speed, visuomotor coordination and attention improved significantly by 11% among coffee consumers compared to non-consumers.
- Cognitive age was calculated to be 6.7 years younger among those who drank the most coffee compared to those who drank the least.
- Inflammatory markers were more than 20% lower in participants drinking five cups daily than in participants drinking less than one cup daily.
- Researchers did not find any interaction between age, sex and coffee consumption."
