Hello kmailloux. First I congratulate you on an amazing healthy life style! Your mention of mild chest pain caught my attention. I have a 4.3 cm ascending aortic aneurysm diagnosed a few years ago. I reduced my exercise after reading through people's experiences on this blog, but I am still very regular. I never exercised to your degree. My chest pain brought me in to get studies, where the aneurysm was discovered. My aneurysm is not what is getting treated, but the chest pain is. My angina results from cardiac micro spasm (diagnosed through an ACTH challenge test during a cardiac cath) along with endothelial dysfunction. I have very opened large arteries. Stress , both physical and perceived emotional/cognitive, are the main triggers. Sometimes its spontaneous. I would recommend to you to look deeper. Your chest pain may not be aneurysm related. Mine is not but it can still be fatal.. I am treated with two forms of nitro.... one for exercise (nitrobid ointment ... which is an old resurrected medication and extremely effective to allow me to do my cardio) and the other are sublingual tabs for rescue pain. I did have to redo my life style, but I can still actively participate in numerous cool activities and sports, just scaled back. I also chose to have the gold standard cardiac cath back when I did not know what was going on. It was recommended, and I was scared. Information can reduce stress and guide our decision making. It should be empowering. I think you need more information. Clarify that chest pain. Good luck! And keep on trekking !!!
