Cardiac arrhythmia not necessarily triggered by coffee consumption, research reports
The idea that drinking coffee increases the risk of developing an irregular heartbeat has been discredited in a new study.
Researchers at the University of California, San Francisco have found that people are 3% less likely to develop forms of arrhythmia or heart complications after drinking a cup of coffee.
Senior scholar Dr Gregory Marcus said, âCoffee is the primary source of caffeine for most people, and it has a reputation for causing or exacerbating arrhythmias.
“But we haven’t found any evidence that caffeine consumption carries a greater risk of arrhythmia.”
He added: “Our population-based study is reassuring that the current caffeine bans to reduce the risk of arrhythmia are probably unwarranted.”
Healthcare professionals often advise patients to reduce their caffeine intake to prevent severe arrhythmias – however, this advice has not been supported by evidence.
As part of the investigation, the team of researchers analyzed 386,258 people to see if there was a link between moderate coffee consumption and a higher risk of arrhythmia by studying the impact of genetic variations on the body. caffeine metabolism.
According to the results, coffee consumption does not increase the risk of arrhythmia, with only four percent of participants developing an arrhythmia.
Instead, it has been revealed that drinking coffee can protect you against developing a heart arrhythmia.
Dr Marcus said: âOnly a randomized clinical trial can demonstrate with certainty the clear effects of consuming coffee or caffeine.
“But our study found no evidence that consuming caffeinated beverages increased the risk of arrhythmia.”
He added, âThe antioxidant and anti-inflammatory properties of coffee may play a role, and certain properties of caffeine may protect against certain arrhythmias. “
All the results of the study are now available in the journal JAMA Internal Medicine.
