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.<\/p>\n
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).<\/p>\n
AFib is the most common heart rhythm disorder, causes the heart to beat rapidly and skip beats, and if left untreated, can cause strokes.<\/p>\n
The results suggest that caffeine intake of up to 300 mg per day may be safe for arrhythmic patients.<\/p>\n
“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.<\/p>\n
But, “caffeinated beverages such as coffee and tea have long-term anti-arrhythmic properties mediated by antioxidant effects and antagonism of adenosine,” he added.<\/p>\n
For the review, published in the journal JACC: Clinical Electrophysiology, the team analysed multiple population-based studies.<\/p>\n
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.<\/p>\n
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.<\/p>\n
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.<\/p>\n","protected":false},"excerpt":{"rendered":"
