Coffee Consumption Associated With Decreased Risk of Heart Failure

Coffee is the third most consumed beverage worldwide. It contains a number of useful nutrients such as vitamin B-2, magnesium, potassium, and antioxidants. A new study suggests that drinking one or more cups of caffeinated coffee per day may help decrease the risk of heart failure.

The researchers used data from the Framingham Heart Study, the Atherosclerosis Risk in Communities Study, and the Cardiovascular Health Study for their study. Participants in the studies included 21,000 adults and each study had at least a 10-year follow-up period. Participants were grouped according to number of cups of coffee consumed per day and all incidences of heart failure were recorded.

Participants who reported consuming one or more cups of caffeinated coffee per day saw a long-term decreased risk in heart failure. The Framingham Heart and the Cardiovascular Health studies showed that the risk of heart failure decreased by 5-12% per cup of coffee consumed daily. Participants in the Atherosclerosis Risk in Communities Study who drank at least 2 cups of coffee per day had a 30% decreased risk of heart failure. No decrease in heart failure risk was seen for decaffeinated coffee.

The study was conducted by researchers from the University of Colorado School of Medicine.It was published online ahead of print on February 9, 2021 in the journal Circulation: Heart Failure.
