A study conducted at Beth Israel Deaconess Medical Center, USA, indicates that risk of heart failure is 11% lower in coffee drinkers
"Our results showed a possible benefit, but as with so many other things we consume, it really depends on how much coffee you drink," says study author Elizabeth Mostofsky. According to her, compared with no consumption, the protection was strongest among people who drank their portions of approximately 236 ml of coffee per day, equivalent to about two American cups (250ml).
Data were analyzed from five previous studies - four in Sweden and Finland - which examined the association between coffee consumption and heart failure. The data refer to reports of 140.220 participants and involved 6522 heart failure events.
In summary of the published literature, the authors found a "statistically significant - J-shaped -" between habitual coffee consumption and heart failure, in which the protective benefits begin to increase until the consumption of approximately two American cups per day ( 472ml). Results indicate that the protection factor is beginning to show slow decline as consumption increases beyond two cups daily. The consumption of about five cups Americans have is not related to any protection against heart failure and may lead to health hazards.
It is not clear why the moderate coffee consumption provides protection against heart failure, but researchers say that part of the answer may lie in the intersection between regular consumption of coffee and two risk factors for heart failure - diabetes and high blood pressure.
"There's a good amount of research showing that drinking coffee reduces the risk of type 2 diabetes," says the study's senior author Murray Mittleman. "Of course, if you reduce the risk of diabetes, you also reduce the risk of heart failure . "
There may also be a benefit in blood pressure. Studies have consistently shown that light consumption of coffee and caffeine increases blood pressure. "But that moderate scale of consumption, people tend to develop a tolerance where coffee drinking is not a risk and may even protect against high blood pressure," says Mittleman.
Second, Mostofsky more research is needed to identify more claramento the effects of coffee on heart failure. "But in the short term, these data may justify a change to the guidelines to reflect the consumption of coffee, in moderation, can provide some protection against heart failure," concludes the researcher.
