Wow these are interesting comments and it really makes me wonder if this is what is wrong with me - I took Amioderone for 7 months ending with my ablation last February. In a pre-ablation echo done a few month prior to the ablation I was diagnosed with mild pulmonary hypertension. Well the EP paid no attention to this on the echo and it was not until I asked about it that the nurse said "oh they don't do anything with that here, you'll need to go to a pulmonary dr. So I self referred and this started a whole lot of lung testing, another echo which still showed PH, pulmonary rehab, trial of a Breo inhaler even tho he has ruled out asthma after testing, and blood tests. He and the new cardiologist I was referred to after the EP was done with me say they don't know what is causing the PH - now I wonder if I have lung damage from Amioderone even tho it was stopped last February? I continue to have chest tightness, SOB at times (climbing stairs, fast walking, and weird little chest pains more like pinches from time to time. I never thought that Amioderone could hang on this long or cause permanent damage.
