Moderate Caffeine May Not Hurt Heart

SAN FRANCISCO, March 8 (UPI) — U.S. researchers say it is unlikely moderate caffeine increases heart arrhythmia risks.

Researchers at the Kaiser Permanente Division of Research in Oakland, Calif., found those who reported drinking four or more cups of coffee daily had an 18 percent lower risk of hospitalization for heart rhythm disturbances and those drinking one to three cups each day had a 7 percent lower risk.


“Coffee drinking is related to lower risk of hospitalization for rhythm problems, but the association does not prove cause and effect, or that coffee has a protective effect,” lead author Dr. Arthur Klatsky said in a statement. “However, these data might be reassuring to people who drink moderate amounts of coffee that their habit is not likely to cause a major rhythm disturbance.”

Klatsky and colleagues looked at 130,054 men and women, ages 18-90 — with the majority age 50 and younger. About 2 percent — 3,317 participants — were hospitalized for rhythm disturbances. Fourteen percent in the study drank less than one cup of coffee a day, 42 percent drank one to three cups of coffee a day, 17 percent reported drinking four cups or more each day and about 27 percent were not coffee drinkers.

The findings were presented at a conference of the American Heart Association held in San Francisco.
