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.

Consumption of Coffee May Reduce MetS: Study

Drinking coffee may reduce heart disease risk

Coffee consumption is associated with reduced risk of metabolic syndrome (Mets), say researchers adding that MetS increases the risk of cardiovascular problems, including coronary heart disease and stroke.

According the study, Assistant Professor Giuseppe Grosso from the University of Catania, Italy, reviewed his own scientific research on the association between coffee consumption and MetS in Polish and Italian cohorts and explored the potential mechanistic perspectives behind the inverse association.

His research suggests that polyphenols contained in coffee may be involved in the inverse association, specifically phenolic acids and flavonoids.

He also reviewed research that suggests that moderate coffee consumption is associated with a reduction of CVD, cancer, all-cause mortality and type 2 diabetes.

For the findings, Associate Professor Estefania from Toledo University of Navarra, Spain, reviewed meta-analyses considering associations between coffee consumption and MetS and discussed work in a Mediterranean cohort.

Her research involved 22,000 people and specifically considered caffeinated and decaffeinated coffee.

The study concluded that moderate coffee consumption (one to four cups per day) was associated with reduced risk of MetS, whilst higher intakes were not.

This was reported for both regular and decaffeinated coffee.

The inverse association between coffee consumption and metabolic syndrome was shown in both men and women, said the study.

Meta-analyses also found that a moderate consumption of both caffeinated and decaffeinated coffee may be associated with a reduced risk of metabolic syndrome.

The study was presented at the 13th European Nutrition Conference organised by the Federation of European Nutrition Societies (FENS) in Dublin, Ireland. (IANS)
