My diagnosis of A-Fib was June, 2021 & the 1st med. Prescribed was Warfarin. That was Toxic Poison to me & Yes, it caused muscle weakness. After a lot of "Pushing", my Dr. switched to Eliquis. That worked for +- 6 months, then Side Effects popped up. After MORE "rankling", the Cardiologist changed me to Xeralto ...but within a Very Short period of time MORE terrible side effects. Finally (the 3rd Cardiologist consulted) I was told to Stop Everything, & see a Cardio-Surgeon. I'd been seeing an MD who believes if you take as Few Pharmaceuticals as possible, eat a Healthy Diet, & live an Active lifestyle, you should be healthy. He did blood tests & ordered a scan of my Carotid Artery. When we looked at it he said, "People Would KILL to have Arteries like yours. They are almost Plaque-Free. You Absolutely Don't Need Blood Thinners! I took this to my Cardiologist, She looked at the scan & said, "That doesn't mean A Thing" ... (My 'Common sense' Disputed her statement so I scheduled an Appt. with a Cardiologist (Who had been written up as one of The Best in the Area) 100 miles from my home, and saw him. He'd spent time looking thru my files (Lots of EKG's, test results, & Physicians emails) - Most Importantly the Carotid Artery Scan & Said, "Actually, the Only thing I could recommend is to take a small-dose aspirin every-other Day, eat a healthy diet - which it looks like you Already do, & get Exercise. I Wish More Patients like you could come visit me. I'd Really like to see you again in 6 months or a year, I'd Like to follow your health, potentially you could live to be 100".
After reading my story, I hope you'll listen to your 'inner voice' & exercise your Good Common Sense. When Dr.'s tell you something that Just Doesn't seem Right, Keep Asking Questions, even it it means consulting Another Doctor. Sooner or later one will come up with A Right Answer FOR YOU! (It's been said for Centuries: "Doctors Practice Medicine". Like Great Musicians they practice & Practice & PRACTICE 'till they finally Get It Right, & We're their Violins, or Pianos, or Trombones or Whatever! For Men: "It Takes A Lot of Practice to get Yankee Stadium!)
I am glad you are doing well, despite having AFib. But it is my understanding that the prescription of blood thinners for AFib has to do with the LAA, the left atrial appendage of the heart where, when you have AFib, it is most likely to form a blood clot there. That is because blood collects there during an AFib episode and pools, with more likelihood of a clot that can lead to a stroke. This has nothing to do with your diet, your arteries being plaque free, etc. It has to do with blood collecting in that part of the heart because during the irregular AFib or flutter beats, it can't pump it out.
I too want to get off the Eliquis. In fact, I had a Watchman device implanted May 1 in the LAA precisely to enable me to do that, but my doc wants me to stay on it until November because he believes that one needs to wait six months after the Watchman to make sure it is completely healed and sealed off. But now I mave weak leg muscles, anemia, and intestinal upset plus fatigue. I told my cardio nurse I can't be on his drug for three more months and need to switch to the baby aspirin. And she said, "it's your choice."
