I had 2 stents March 2023 (thru arm), I had 1 more stent August 2023 (arm). I was still having issues - fatigue, feeling I would pass out often (almost daily), general weakness. So in November, cardiologist ordered another angio to take another look at the stents - this time thru groin, because my arm artery was not completely healed. (I guess sometimes, not often, a stent can move or a side artery can be partially blocked by a stent). Everything checked out good. The 3rd angio, before I even realized they were starting the cardiologist was leaning over telling me all was good - it's not your heart. The longest part of the whole process was the prep - maybe 15 minutes. The angio itself took maybe 2-3 minutes. I felt nothing, and I didn't/couldn't see anything. Bottom line - nothing to worry about. I didn't even know he was doing it. Groin entry is a little more invasive then the arm. They prefer to go thru arm. I think recovery takes a little bit longer thru groin and I felt some fatigue afterwards for maybe 2-3 days. Really, the only way to know for sure if there is a block or not is to take a look, angio.
