New studies from the American College of Cardiology: 2 or 3 cups of coffee a day are good for the heart | Tunisian press

According to American researchers, drinking two or three cups of coffee a day will have many benefits: it reduces the risk of cardiovascular diseases and also extends life expectancy.

Historically, coffee has long been considered an enemy of the heart by doctors. Its widespread consumption has been discouraged by heart patients, especially during arrhythmias and, in particular, atrial fibrillation (AF). But findings recently presented at a recent conference of the American College of Cardiology (ACC), that coffee is good for the heart, regardless of its form (ground, instant or even decaffeinated), contradict this belief. .

Nearly 400,000 topics Followed for 10 years

In the first study, scientists examined data on more than 380,000 people with an average age of 57 (52% of them women) without heart disease over a 10-year period to see if coffee consumption played a role in heart disease or stroke. According to published findings, drinking 2-3 cups of coffee per day was associated with the greatest benefit, resulting in a 10-15% reduction in the risk of coronary heart disease, heart failure, arrhythmia, or death, all of the causes combined. Thus, the risk of stroke or death from heart disease was lower in people who drank one cup of coffee a day. In this regard, the researchers noted a U-shaped relationship between coffee consumption and the occurrence of heart rhythm problems. The maximum benefit was observed in people who drank two to three cups a day, with less benefit for those who drank more or less. The second study included 34,279 participants with cardiovascular disease at baseline. The analysis showed that drinking 2-3 cups of coffee per day was associated with a lower risk of death, compared to no coffee. No coffee consumption was associated with an increased risk of heart rhythm disturbances.

Both studies also indicate that coffee contains more than 100 biologically active compounds. These substances can help reduce oxidative stress and inflammation, improve insulin sensitivity, increase metabolism, inhibit fat absorption from the gut, and block receptors known to be involved in heart rhythm disturbances.

Which type do you choose?

In a third study, researchers examined whether there were any differences in the relationship between coffee and cardiovascular disease depending on whether an individual drank instant or ground coffee, caffeinated or decaffeinated. And, again, they found that drinking two to three cups a day was associated with the lowest risks of arrhythmias, heart blockages, stroke, or heart failure, whether they drank ground or instant coffee. Lower mortality rates were observed for all types of coffee (ground, instant, decaffeinated, etc.). This work also indicates that caffeine is not alone in driving the benefits associated with coffee.

Thus, in conclusion, the authors of these three studies believe that drinking coffee regularly, even when you have heart disease, is not a problem. This consumption does not increase the risk of atrial fibrillation and an improvement in coffee-related survival has been found even in the case of atrial fibrillation.
