In the latest study published in the medical journal JAMA Internal Medicine, scientists found that people who regularly consume coffee have a lower risk of atrial fibrillation than those who drink less.
Accordingly, researchers surveyed the coffee consumption status of 386,000 people over three years and compared it with the rate of heart rhythm disorders (including atrial fibrillation).

Dr. Gregory Marcus - Professor of Cardiology at the University of California San Francisco said that after considering factors such as lifestyle, health status and underlying diseases that can lead to arrhythmia, the survey showed that each cup of coffee will help regular drinkers reduce the risk of heart rhythm problems by 3%.
The research team also looked at the gene segment associated with rapid heartbeat after drinking coffee. Specifically, the CYP1A2 gene, also known as the “coffee gene,” is mutated due to regular coffee consumption. People who possess this gene can drink coffee without experiencing side effects.

However, when this gene is mutated, the body's ability to convert coffee will slow down, causing "coffee hangovers" to last longer or become more pronounced.
In this study, scientists found no link between coffee conversion and the risk of arrhythmia.
The theory that coffee causes heart arrhythmias is based on small, outdated studies that focused only on men, Dr. Marcus and his team point out.

Science today has a different view on coffee. In fact, modern scientific studies show that regular coffee consumption brings more benefits to the human body than harm.
These benefits include reducing the risk of cancer, diabetes, heart disease and serious illness.
