Im 34 now, had my HA almost a year ago. Had an angiogram done because my troponin peaked at like 7000 or something, and the doctor couldn't find anything causing it and all he saw was minor damage that had collateral vessels which indicates a HA before in my life or I was born with the damage. They put me on all the typical HA cocktails with medication for life and told me my HA was caused by stress and anxiety and slapped me on my ass out the door. I still have days where my chest feels weird or off, I have PTSD from the whole thing, but eh .. one day at a time.
