People who drink at least one coffee a day (with caffeine), have a reduced risk of heart failure, according to a new major US study, which comes to dispel the widespread notion that coffee definitely hurts the heart.
Investigators, led by Assistant Professor of Cardiology David Cao of the University of Colorado School of Medicine, who made the relevant publication in the American cardiological journal “Circulation: Heart Failure», analyzed data for more than 21.000 individuals.
From research, διαπιστώθηκε ότι όσοι ανέφεραν πως έπιναν έναν ή περισσότερους καφέδες την ημέρα είχαν μικρότερο κίνδυνο να διαγνωσθούν με καρδιακή ανεπάρκεια. Ο κίνδυνος σε βάθος δεκαετιών ήταν μειωμένος κατά 5% to 12% for each above cup of coffee a day, in relation to its non-consumption.
As estimated, the risk of heart failure was approx 30% lower for those who drank at least two coffees daily. From the other side, Consumption of decaffeinated coffee seems to have the opposite effect, increasing the risk of heart failure.
"The relationship between caffeine and the risk of heart failure surprised us. Coffee and caffeine are often considered by the general population to be harmful to the heart, because people associate them with increased pulses, with hypertension etc..
Nevertheless, the clear link between increased coffee consumption and a reduced risk of heart failure comes to completely reverse this perception. ", said Dr. Cao.
«Fri.’ all these, do not exist yet - sufficiently- clear evidence leading to the recommendation to increase coffee consumption, to reduce the risk of heart failure, at least with the same clarity and certainty that exist for smoking cessation, weight loss or exercise ".
The researchers pointed out that popular coffees, with many calories due to the addition of sugar and fatty dairy products, can burden the heart. also, caffeine, despite its benefits, can become dangerous in large quantities. In addition, Children should avoid caffeine and any beverages that contain it.
Another recent Japanese study, led by Osaka University Professor of Public Health Hirogiasu Iso, which was published in the American medical journal "Stroke" (Stroke), found that people who have had a heart attack or stroke in the past can reduce their risk of a new heart attack and death by drinking green tea and coffee daily..
The study, who analyzed data for more than 46.000 people from 40 to 79 years, found that those who had lived after a first heart attack and drank a coffee a day, they had about 22% lower risk of death than those who rarely drank coffee.
People without a history of stroke or heart attack who drank one or more coffees a day, they had 14% lower risk of death, compared to those who did not drink coffee at all.
