UCSF researchers share good news for coffee drinkers
In the largest study of its kind, an investigation by UC San Francisco has found no evidence that moderate coffee consumption can cause cardiac arrhythmia.
In fact, each additional daily cup of coffee consumed among several hundred thousand individuals was associated with a 3 percent lower risk of any arrhythmia occurring, including atrial fibrillation, premature ventricular contractions, or other common heart conditions, the researchers report. The study included a four-year follow up.
“Our population-based study provides reassurance that common prohibitions against caffeine to reduce arrhythmia risk are likely unwarranted,” says senior and corresponding author Gregory Marcus, M.D., professor of medicine in the Division of Cardiology at UCSF.
