Thanks for asking HCM i think by now you know what is ischemic cardiac myopathy...its hardeneing of arteries..due to plagues...which accumulated due to excess consumption of fat. If we got to treat you... 1. you should change your life style avoid alcohol strictly no even a 10 ml of wine incase if you take . 2.drink healthy food cooked in less oil/boiled or steamed food. 3 avoid caffeine less fat food And coming through treatment process seeing you ejection fraction and age consideration we cant perform surgery.after 3 to 4 weeks of observation in your health you may needed a pace maker to control your heart rate. and also myopathy leads to hearts failure to control you need metaprolol drug. digoxin etc.as these are prescribed drug i suggest you to go and meet a cardiologist for these medicines and coming to your adrenal gland hyper function which you clearly didn t mention which levels r elevated like cortisol or aldosterone the elevated levels are the cause leading to itching you may need steroid treatment for management under supervision
