Scientists from the USA made conclusions about the effect of coffee on the heart rate

1 < p>For a long time it was believed that people with heart rhythm disorders should avoid drinking coffee because caffeine can trigger arrhythmias. They were recommended to drink as little as possible of this drink or even to give it up altogether.

However, a study by American scientists proves that coffee probably does not pose a danger to such patients.

To understand whether caffeine can really cause an accelerated or irregular heartbeat, employees of the cardiology department of research at the University of California in San Francisco analyzed data from more than 386,000 people who participated in a long-term health study. Of this large group, approximately 17,000 people developed heart rhythm disorders, which occurred in an average of 4.5 years.

Participants were asked about the frequency of coffee consumption. “We couldn't find evidence that those who drank more coffee experienced an increased risk of heart rhythm disturbances,” said Dr. Gregory Marcus, associate director of cardiology research at the University of California.

Also, according to according to scientists, drinking an extra cup of coffee every day can even reduce the risk of arrhythmia by an average of 3%. According to Marcus, further research is needed to find out exactly how coffee affects the heart and why it can protect against arrhythmia, as his colleagues believe.

The expert notes: some inflammation can contribute to heart rhythm disturbances, and coffee has an anti-inflammatory effect. It may also be that caffeine encourages some people to be more physically active, which also reduces the risk of cardiovascular problems.

However, Dr. Zachary Goldberger, associate professor of cardiovascular medicine at the University of Wisconsin-Madison, cautions against rushing. conclusions, writes HealthDay. Both experts also admit that there are probably people who do not react well to coffee.
