Coffee lowers risk of heart failure, stroke drastically

Another team of researchers found that increasing coffee consumption by one cup per week reduced the risk of heart failure by seven per cent and stroke by eight per cent.

The findings were presented at the American Heart Association's Scientific Sessions meeting in Anaheim, California. Carsten Görg and David Kao, who both conducted this study, used machine learning alongside traditional data analysis techniques to uncover an inverse relationship between how much coffee we drink per week and how exposed we are to heart failure and stroke.

The machine result also pointed to red meat being a risk factor in heart failure and stroke, but due to differing definitions of red meat, they could not draw the same conclusion across all three studies.

Following the machine learning data analysis, Stevens and colleagues found that an extra cup of coffee every week is associated with a 7 percent lower risk of heart failure and an 8 percent lower risk of stroke.

Researchers at the University of Colorado studied how certain foods impact heart health andfound coffee is key to a healthier heart. "The risk assessment tools we now use for predicting whether someone might develop heart disease, particularly heart failure or stroke, are very good but they are not 100 percent accurate", said Laura M. Stevens, B.S., first author of the study and a doctoral student at the University of Colorado School of Medicine in Aurora, Colorado and Data Scientist for the Precision Medicine Institute at the American Heart Association in Dallas, Texas.

The findings about coffee consumption came about after re-analysing data from the Framingham Heart Study, a long-running USA investigation of heart disease risk factors involving thousands of participants.

The new study was observational, meaning it can identify an association, but cannot prove cause and effect.

Another potential risk factor identified by machine-learning analysis was red-meat consumption, although the association between red meat consumption and heart failure or stroke was less clear.

While many risk factors for heart failure and stroke are well known, the researchers believe it is likely that there are as-yet unidentified risk factors.

The findings are supported by two other studies published earlier this year that found that coffee-drinking seems to significantly reduce the chance of dying from heart disease. "Ultimately, our key goals are to determine whether coffee consumption is a clinically useful part of cardiovascular disease risk assessment", she says, "and whether changing coffee or caffeine consumption may be a way of altering that risk".
