High coffee consumption is not linked to the risk of having irregular heartbeat, new research says.
Earlier studies have put forward that increased coffee intake may elevate the possibility of having cardiac arrhythmias, specifically atrial fibrillation. According to Medical News Today, a new study, which was either conducted in the United States or in Sweden, determined the associations between high coffee consumption and the risk of having atrial fibrillation.
The trial involved about 250,000 people coming from either of the two countries.
The first part of the trial consisted of 76,745 men and women. In 1997, the participants reported the number of cups of coffee they had per day and they were followed up for a decade and two months. The findings revealed that the median daily coffee consumption was three cups.
Meanwhile, the second part of the trial involved a follow-up meta-analysis that consisted of four prospective studies. In this study, the population went up to 248,910 participants.
The research findings revealed that even though there were 10,406 cases of atrial fibrillation diagnosed, the study team found out that coffee intake was not linked to the incidence rate of the irregular heart rhythm. Also, boosted levels of coffee intake did not factor in to the presence of atrial fibrillation.
With regard to gender, the results of the specific analysis revealed that coffee consumption was linked with a higher risk of atrial fibrillation in men while there was a lower risk of having the arrhythmia in women. While the findings indicate that men have higher level of sensitivity to increased coffee consumption than women, further research has yet to be taken into account.
Over the last few decades, coffee consumption has significantly doubled, from about 3.5 million tonnes in a global scale in the 1970s to 7 million tonnes today. With the figures doubling, doing this sort of trials are now viewed as important.
Lead author Susanna Larsson said that with coffee intake having no direct detrimental associations to cardiovascular health, people who love drinking coffee can continue consuming it in moderation without any worries of developing a risk of having atrial fibrillation.
Meanwhile, the researchers claim that the trial does not indicate that increased coffee intake is not related to other kinds of irregular heart rhythm, as there were reports of decreasing coffee intake among participants with atrial fibrillation during study baseline after it elicited arryhtmia.
Researchers keep an eye on coffee consumption because of its content caffeine, according to Web MD. University of California, San Francisco cardiologist Tony Chou said that one cup of coffee contains about 100 milligrams of caffeine, which is sufficient to pose a potent “kick” to occasional coffee drinkers. In fact, 30 minutes after drinking coffee, the person’s metabolic rate goes up to 10 percent, along with an increase in blood pressure, heart rate, and respiratory rate.
While caffeine in coffee was previously linked to having arrhythmias like atrial fibrillation, the substance also has a number of benefits. Wright State University Ohio neurology professor Michael Bonnet said that caffeine allows people to stay alert. In addition, caffeine boosts calcium, a mineral that is vital to memory.
People may have been scared of drinking coffee due to its previous links to heart problems; however, with the new research information, they may no longer fear to sip in their favorite cup of coffee.
