Careful about Coffee and Heart Failure

English: A photo of a cup of coffee. Esperanto...

There is a lot in the press about coffee and and it’s effect on Heart Failure. We would ask you to tread carefully and use common sense before acting on press reports as the important word used by the clincian in the report below is “association”. Remember coffee has caffeine that is a stimulant and definitely makes your rate increase which is not what we are trying to do when we have a Heart Condition.”Drinking coffee moderately may reduce the risk of heart failure, but drinking  too much makes this benefit disappear, according to a new review.

People who drank two cups of coffee a day were 11 percent less likely to have  heart failure, compared with people who drank no coffee. Heart failure occurs  when the heart cannot pump enough blood to meet the demands of the body, and can  be caused by factors ranging from high blood pressure to pregnancy.

Constantly drinking too much coffee, however, negates this benefit: no  difference in heart failure risk was seen between non-coffee drinkers’ and those  who drank more than three cups a day.

“As with so many things, moderation appears to be the key here,” said study  author Dr. Murray Mittleman, director of the Cardiovascular Epidemiology  Research Unit at Beth Israel Deaconess Medical Center in Boston.

The study showed an association, not a cause-and-effect link.

Still, there is reason to think coffee lowers heart failure risk, the  researchers said. Moderate coffee consumption may increase drinkers’ caffeine  tolerance, which could in turn limit their susceptibility to high blood  pressure. Additionally, coffee drinking has been shown to lower the risk of type 2 diabetes.  Diabetes and hypertension are major risk factors for heart failure, Mittleman  said.

People who have already have heart failure should consume no more than one to  two cups of coffee per  day, according to the American Heart Association.

The finding “is good news for coffee drinkers,  of course, but it also may warrant changes to the current heart failure  prevention guidelines, which suggest that coffee drinking may be risky for heart  patients,” said study author Elizabeth Mostofsky, a research fellow at the  center.

The researchers looked at data collected on 140,220 people in Sweden and  Finland who participated in five previous studies. There were a total of 6,522  cases of heart failure between 2001 and 2011. The causes of heart failure often  cannot be reversed, but the condition can be treated.

The researchers took into account the differing serving sizes between Europe  and the United States (European servings are generally smaller), however, they  did not account for coffee’s strength or whether the coffee was caffeinated,  though they noted that in northern Europe, it typically is.

The study was published yesterday (June 26) in the journal Circulation Heart  Failure.
