Damn, sorry to hear your having problems, sounds like the discussion I had many many years back with an x saying AAS is the same as Cocaine, no bitch it ain't! It can be a mental addiction but hell, so can many other things. And people are fine with smoking cigs and booze, and popping pain pills to no end, but oh AAS to enhance your physic and your the devil. It's out of sheer ignorance. My wife knew as soon as we met, I made no excuses, just this is who I am, this is what I do, like it or leave it, either way. She stayed, even pins me when I need it.
As far as an enlarged heart... Left sided hypertrophy, the bigger the left side of the heart ( the side that pumps out oxygenated blood) gets the less effective it becomes as a pump, the myocardial (heart muscle) wall gets thick and causes a stiff squeeze, so the EF (ejection fracture) how much blood is pumped out with one stroke decreases, this leads to less circulation, less blood through the kidneys and that means less toxins are filtered along with fluids= CHF or congestive heart failure.
