I had open heart surgery with at triple bypass & aortic valve replacement 12 years ago and am fine ever since.
However I do have very occasional and short afib, usually not longer than a minute or two. A year ago I had a 20+ afib event that was only stopped with an IV with Cardizem.
They would have let me go but my troponin levels were up and the next day they did a full heart workup on me - stress test, EKG, and much more.
Everything checked our A+++++ like I’d never had heart disease.
Troponin levels can be a false flag.
the 20+ afib events would have caused the troponin level increase.
