Australian scientists from the Baker Institute found that frequent coffee consumption is not dangerous to the heart and can even reduce the frequency of arrhythmias. This is reported in a press release on the site EurekAlert! . Scientists have analyzed the results of studies on the search for a link between caffeine and atrial and ventricular arrhythmias. In one of the scientific works with the participation of 228 465 people it was shown that with the use of coffee, the risk of atrial fibrillation decreases. Another study, in which 115,993 patients participated, demonstrated a reduction in the incidence of fibrillation by 13 percent. According to experts, only a few cases indicate the harm of coffee. Caffeine acts as a stimulant of the nervous system and blocks the action of adenosine, which promotes atrial fibrillation. In addition, a dose of caffeine, equal to 500 milligrams per day, does not affect ventricular arrhythmia. In patients who underwent myocardial infarction and received an average of 353 milligrams of caffeine per day, the heart rate was normalized. The risk of gastric arrhythmias was increased only in those people who drank 9-10 cups of coffee a day. In general, the daily safe dose is 300 milligrams, but some people may be more susceptible to it. More important news in the Telegram channel «The ribbon of the day» . Subscribe!
