A new study has found that there is no relation between drinking coffee and an increased risk of atrial fibrillation, according to research published in the open access journal BMC Medicine.
The research includes a meta-analysis of four other studies, making it the largest study its kind, involving nearly 250,000 individuals over the course of 12 years to investigate a possible link between a common irregular-heartbeat condition and drinking coffee.
Lead author Susanna Larsson, PhD, Associate professor at the Institute of Environmental medicine said, “The results of the study says It is safe to consume Coffee, at least in moderation, without the risk of developing this condition.”
Moderate coffee consumption has been associated with a reduced risk of coronary heart disease and stroke. The current study revealed that 41,881 men and 34,594 women in 1997, reported how many cups of coffee they consumed and were followed up for 12 years. There were 4,311 and 2,730 incident AF cases in men and women, respectively, in the two cohorts. The median daily coffee consumption was three cups among both men and women.
The authors says in sex-specific analyses, coffee consumption was associated with a non-significant increased risk of AF in men, but a non-significant decreased risk of AF in women. Whether men may be more sensitive to a high coffee or caffeine intake warrants further study.
Although available evidence does not indicate that coffee consumption increases the risk of developing AF specifically, coffee may still trigger other forms of irregular heartbeat.
Coffee or Tea?
As long as sugar and cream are avoided with these beverages, ill-effects can be reduced radically, suggest numerous studies leaving us to decide how to economize our habit of drinking these beverages. Both have been serving humans for thousands of years and they remain so for few more.
The latest finding was by the Kangbuk Samsung Hospital, Seoul in South Korea, which examined the link between coffee consumption and the presence of coronary artery calcium (CAC) which is an early indicator of coronary atherosclerosis, when arteries get clogged, leading to heart attack or a stroke. The team studied a group of 25,138 men and women aged in mid-40s had no signs of heart disease.
The calcium ratios were 0.77 for people who had less than one cup per day, 0.66 for those having one to three cups every day, 0.59 for those consuming three to five cups per day, and 0.81 for people having at least five cups or more every day compared with non-coffee drinkers.
Essentially both beverages — coffee and tea — gained popularity in Asia before the Europeans arrived in the 17th century to make these beverages truly global.
