Caffeine May Be Good For Your Heart Too, Research Says
According to a new study from the University of California, San Francisco, caffeinated drinks may be not so bad for our heart. In fact, it can actually bring us cardiovascular health benefits.
It has long been believed that downing on a strong coffee in the morning can trigger dangerous heart palpitations. But the new study suggests that it can deliver a much needed boost without setting the heart racing. The researchers found that consuming caffeine does not lead to extra heartbeats, which although common, can lead occasionally lead to heart or stroke-related deaths.
As a matter of fact, people are missing out on some of the potential health benefits of caffeinated food and drinks, such as chocolate and tea - researchers suggest.
’Clinical recommendations advising against the regular consumption of caffeinated products to prevent disturbances of the heart’s cardiac rhythm should be reconsidered, as we may unnecessarily be discouraging consumption of items like chocolate, coffee and tea that might actually have cardiovascular benefits.’, says Dr Gregory Marcus - the lead author of the study.
’Given our recent work demonstrating that extra heartbeats can be dangerous, this finding is especially relevant.’
One of the most common symptoms is heart palpitations or someone having an unusual awareness of heartbeats and have been linked to stroke and death. Premature ventricular contractions, where the heart skips a beat, (PVCs) have been linked to an increase in heart failure, coronary artery disease and death.
While both abnormalities have been tied to coffee consumption in past studies, Marcus and his team note that past research did not use PACs and PVCs as a primary outcome.
But health guidelines state that if a patient’s history is consistent with premature extra beats, potential exacerbating factors - such as caffeine, alcohol and nicotine - should be eliminated.
A growing body of research suggests that caffeinated products like coffee, tea and chocolate have cardiovascular benefits. In the current study, frequent consumption of these products was not associated with extra heartbeats.
The study, published in the Journal of the American Heart Association, still requires further investigation, the researchers add.
