Hi there @irishpeaks , that was good to hear you don't have an issue with elevation. I live literally 500 feet above sea level, and every time I went to higher elevations for hikes to Mt. Lassen, Mt. Shasta or Mt. Anything I suffered! Short of breath, dizzy, gasping for air...I knew something was wrong, and it kept getting wronger! There are so many forms and causes of cardiomyopathy, it is like a catch-all phrase. Hypertrophic Obstructed Cardiomyopathy is a bit different than non-ischemic cardiomyopathy, but I am glad to hear you do not have issues with elevation. I feel bad you have a 'full block', that has to be limiting and always in the back of your mind. Hopefully the meds you are on are helpful. Colorado has some BIG mountains. Like the real deal mountains. Are you able to get out and enjoy their beauty? 8500 ft., I bet you got some snow this year!
