man you are very very lucky. they say the aortic anurism(sp) is what boston lyod dropped dead from. it's like a ticking time bomb and can rupture at any time and 9 out of 10 times it is fatal. if you had a bypass done as well i would be leary of pushing hefty doses anymore and would probably opt for more of a hrt plus at most. since you already have plaque build up going on then you are already at risk so that's just my thoughts but glad you got that fixed and are back on the mends
