Are you an ardent coffee or tea lover, but advised to avoid caffeinated beverages due to your heart conditions Cheer up, drinking upto three cups of coffee or tea a day is safe as well as reduce irregular heartbeat and stroke risk, a study says.

A single cup of coffee contains about 95 mg of caffeine. It acts as a stimulant to the central nervous system and works to block the effects of adenosine — a chemical that causes atrial fibrillation (AFib).

AFib is the most common heart rhythm disorder, causes the heart to beat rapidly and skip beats, and if left untreated, can cause strokes.

The results suggest that caffeine intake of up to 300 mg per day may be safe for arrhythmic patients.

“There is a public perception, often based on anecdotal experience, that caffeine is a common acute trigger for heart rhythm problems,” said lead author Peter Kistler, Director at Melbourne’s Alfred Hospital.

But, “caffeinated beverages such as coffee and tea have long-term anti-arrhythmic properties mediated by antioxidant effects and antagonism of adenosine,” he added.

For the review, published in the journal JACC: Clinical Electrophysiology, the team analysed multiple population-based studies.

A meta-analysis of 228,465 participants showed that AFib frequency decreasing by 6 per cent in regular coffee drinkers, and an analysis of 115,993 patients showed a 13 per cent reduced risk.

Another study of 103 post-heart attack patients who received an average of 353 mg of caffeine a day showed improvement in heart rate and no significant arrhythmias — or abnormal heart rhythms, that cause the heart to beat too fast, slow or unevenly.

However, in two studies, where patients drank at least 10 cups and nine cups of coffee per day, showed an increased risk for ventricular arrhythmias (VAs) — a condition in which the lower chambers of the heart (ventricles) beat very quickly.

Are you expecting? If so, refrain from drinking coffee, as babies born to women who drank coffee during pregnancy were found to be at a higher risk of being overweight, claims a study.

Consumption of even one or two cups of coffee per day by expectant mothers can put their babies into a higher risk of being obese at school age.

“There may be good cause to increase the restriction of the recommended maximum of three cups of coffee per day. Caffeine is not a medicine that needs to be consumed,” said Verena Sengpiel, Associate Professor at the University of Gothenburg’s Sahlgrenska Academy in Sweden.

However, the clear link between caffeine and the cause of obesity is not yet proved, the study showed.

Published in BMJ Open Journal, the team included 50,943 expectant mothers. The children born to women who had consumed caffeine during pregnancy were studied till they were eight years old.

During the study, children aged five years old, who were overweight or obese were five per cent greater in the group whose mothers had the highest caffeine consumption in the study, compared to those whose mothers had the lowest caffeine consumption.

The risk of child obesity due to prenatal caffeine consumption was also seen among women who followed the recommended amount as according to the National Food Agency, i.e. three cups of coffee every day.

Even though further studies are needed, it is better to reduce the consumption or completely refrain from caffeine intake during pregnancy, Sengpiel advised. (IANS)
