It doesn't work that way. RBC/HCT being under control reduces your chances of a stroke or clotting. Blood pressure pressure being in a healthy range reduces the risks of organ damage and venous destruction.
As these are connected to the heart, of course they're factors by association alone.
Medicine doesn't even know fully what causes LVH beyond strain on the left ventricle, causing an imbalance. Hell, read the risk factors some time; they're the exact same as everything else that will kill you: age, obesity, diabetes, cardiovascular health, smoking, et cetera.
I'd love to look into my crystal ball and tell you how you're going to die, but unfortunately I'm not a psychic or time traveler - so you're just going to have to try to live healthy like the rest of us.
Just don't go pushing ideas on others without being able to show definitive proof. There is a member on here that I have the utmost respect for, and he DOES believe it to be a potential risk - but he is waiting (like me) for it to become fact before stating AAS adds to the risk.
