Caffeine doesn’t cause cardiac stress, study finds
A recent study dispelled one of the longest lingering medical suspicions about caffeine, namely that it may stress the heart and cause disturbances in cardiac rhythm. Researchers from University of California at San Francisco found that coffee, tea and chocolate intake was not associated with heart palpitations, heart fluttering and other unusual heartbeat patterns. After evaluating the caffeine intake of 1,388 people with an average age of 72, they could not find any indication of premature contractions and recommend to continue regular consumption due to other health benefits of caffeinated beverages. The findings are especially meaningful since recent studies indicate that heart palpitations or fluttering may be associated with future heart failure, atrial fibrillation and other dangerous conditions.
