“Coffee Is Generally Heart-Friendly”
But it may be linked to a slight rise in high blood pressure, researchers say Coffee drinkers can take heart from a series of studies presented this week at
American Heart Association conferences in San Francisco. For example, coffee drinkers appear to have a lower risk of hospitalization for abnormal heart rhythms. And there's no indication that having a few cups every day increases the risk of atherosclerosis, the thickening of blood vessel walls that can lead to heart attacks and other problems. What's more, something in coffee other than caffeine might be responsible for a reduced risk of diabetes for women who regularly imbibe java. But it may be linked to a slight rise in high blood pressure The heart rhythm research looked at the rate at which 130,054 members of the
Kaiser Permanente Medical Care Program were hospitalized for heart rhythm disturbances. About 2 percent of them had hospital stays because of such abnormalities, the most common being atrial fibrillation. But the risk was 18 percent lower for those who reported drinking four or more cups of coffee a day, compared to those who didn't drink coffee, said Dr. Arthur Klatsky, a senior consultant in cardiology for the program, who led the study.
"It might be a surprise, because coffee does give some people the jitters,"
Klatsky said. "And I don't think we're ready to tell people they should drink coffee to prevent heart rhythm problems."
The study didn't offer any reason why coffee might reduce heart rhythm problems, Klatsky said. "It could be that coffee drinkers have better diets or exercise more. We can't say for sure that it might not be related to minor heart rhythm problems that don't require hospitalization."
The bottom line: "Coffee drinkers don't have to quit because they have heart rhythm problems," Klatsky said.
