I could NOT agree more. Privately, cardiologists have expressed to me their concerns over the ubiquitous use of proton pump inhibitors (PPIs) , for example, which first were prescription, now over-the-counter - for GERD, hearburn, reflux (Nexium, Aciphex, many, many brands - all these drugs have "...prazole" at the end, like omeprazole). Not only do they significantly raise the risk of heart attack but can cause low magnesium, producing heart arrhythmia. Yet, docs often don't know this, don't have time to read all the literature and, frankly, PPIs make patients shuttup about their heartburn and reflux and stop complaining - but at what cost? It was thought for years PPIs would reduce the risk of gastroesophageal cancer in those with Barrett's - that is now questionable, too. Anyway, my point is that there is much that can be done with lifestyle changes and critical thinking about what might have precipitated arrhythmia, including a-fib.
