James P. Crowley and Professor Erwin Loh About Caffeine and It’s Positive Effects
James P. Crowley, Professor of Medicine emeritus at Brown University, reposted Professor Erwin Loh’s post on LinkedIn:
“Caffeine appears to do the opposite of what you might think when it comes to the heart. Scientists have found that a cup of coffee a day actually protects the heart from atrial fibrillation – a condition that can lead to stroke and heart failure.
In the DECAF (Does Eliminating Coffee Avoid Fibrillation) trial, the researchers found that caffeine resulted in a 39% lower risk of recurrent AF events, compared to those who abstained – and they have a few theories as to why this might be the case.
“Coffee increases physical activity which is known to reduce AF,” said senior author Professor Gregory Marcus from the Division of Cardiology at UCSF.
“Caffeine is also a diuretic which could potentially reduce blood pressure and in turn lessen AF risk.
Several other ingredients in coffee also have anti-inflammatory properties that could have positive effects.””
