Hi. Thank you for your question and welcome to HCM. I carefully read your concern. Well, initially, your age would help a lot. Anyway, I will try to be thorough in my answer. My opinion is that you should not be restricted only on EKG, and further investigations should be undertaken. Angina, the chest heaviness in the midden part of it, that comes from a coronary artery atherosclerotic plaque of various severity, usually starts as episodes arising on physical effort. Although, we cannot exclude the cases that it arises even at rest. Therefore, I would recommend you to go on with an echocardiogram and a cardiac stress test, for further evaluation and confirming or excluding the coronary artery origin of this concern. I hope I was helpful. Take care.
