Scientists from the University of California in San Francisco found that regular coffee drinking is linked to a much lower risk for arrhythmias.

The research was conducted by Eun-Jeong Kim et al.

Arrhythmia is a fault in the heart’s electrical system, which affects your heart’s pumping rhythm.

The abnormal electrical activity makes the heart muscle beat too fast, slow or in an irregular way. In a healthy heart, you don’t feel your heartbeat.

In the study, the team examined the link between caffeine drinking and the risk for arrhythmia among 357,022 people in the U.K. Biobank.

The researchers found that during 5 years of follow-up, there were 8,159 incident arrhythmias diagnosed (6,999 atrial fibrillation or atrial flutter, 890 supraventricular tachycardia, 459 ventricular tachycardia, and 385 premature ventricular complex).

Coffee drinking was linked to a much lower risk for arrhythmia compared with no coffee drinking.

The team also found that each additional daily cup of coffee was linked to a lower incidence of arrhythmia.

Except for premature ventricular complexes, there was a reduction in arrhythmia risk observed for each subtype of the disease.

The team says the findings should reassure patients and doctors of the low risks linked to regular coffee drinking.

They hope it will encourage providers to work directly with patients to determine and personalize their specific lifestyle factors, including caffeine consumption.
