Scientists have answered whether the popular belief that coffee is harmful to the cardiovascular system (in particular, the risk of arrhythmia) is justified.
Coffee is beneficial in the prevention of arrhythmia, a heart rhythm disorder. This is reported by the specialized portal JAMA Network. Scientists from the University of California came to this conclusion after examining the effect of coffee on heart rhythm. They analyzed data on the health, genetic characteristics, and consumption of the drink of about 390 thousand people.
As a result of the study, experts found that the popular opinion about the harm of coffee to the cardiovascular system (in particular, the risk of arrhythmia) is unfounded.
Experts have found that each additional cup of coffee during the day reduces the risk of arrhythmia by three percent. In particular, the drink helps fight heart rhythm disorders such as atrial fibrillation and supraventricular tachycardia.
