Having one or more cups of caffeinated coffee a day may reduce the risk of heart failure, new research by the University Of Colorado School Of Medicine in Aurora suggests.

There was one caveat, however: Decaffeinated coffee doesn't appear to provide the same protection as caffeine-rich blends.
Researchers in their study, analysed data from more than 21,000 U.S. adults who took part in three major studies: The Framingham Heart Study, The Atherosclerosis Risk in Communities Study and The Cardiovascular Health Study. Participants were followed for at least 10 years.

In all three studies, drinking one or more cups of caffeinated coffee a day was associated with decreased long-term risk of heart failure.

In the Framingham Heart and the Cardiovascular Health studies, the risk of heart failure fell by 5%-12% per cup of coffee each day, compared with having no coffee.

The Atherosclerosis Risk in Communities Study found that the risk of heart failure didn't change with 0 to 1 cup of coffee per day, but was about 30% lower in people who had at least 2 cups a day.

The findings for decaffeinated coffee were different. The Cardiovascular Health Study found no link between decaf and heart failure risk, while the Framingham Heart Study found that decaf was associated with a significantly higher risk of heart failure.

Further analysis showed that caffeine from any source appeared to be associated with decreased heart failure risk, and that caffeine played at least some role in coffee's apparent heart benefit.

Still, the findings can't prove cause and effect, and they also don't mean that coffee is any substitute for healthy living when it comes to your heart, the researchers said. “It is intriguing that these three studies suggest that drinking coffee is associated with a decreased risk of heart failure and that coffee can be part of a healthy dietary pattern if consumed plain, without added sugar and high fat dairy products such as cream.”

"There is not yet enough clear evidence to recommend increasing coffee consumption to decrease risk of heart disease with the same strength and certainty as stopping smoking, losing weight or exercising," they added.
