You don't want to have too much hypertrophy in the heart for sure. My understanding though is that it's very hard (almost impossible?) for it to be a problem without exogenous hormones, or some other condition that allows you to accrue an abnormal amount of muscle mass (e.g. myostatin defficiency).
Edit: I mean someone with a healthy fat percentage body composition. Of course having to pump blood to a 300lb-140kg body is problematic for the heart, be it a mostly fat or mostly muscle body composition. My point is it's just much easier to be fat enough for it to be a problem than muscular enough without exogenous hormones or an abnormal condition.
Telmisartan, an ARB generally used for BP management, can actually reverse LVH to a significant degree over time, though. Popular for bodybuilders on large quantities of AAS for that reason.
