As I attempted to suggest earlier, I doubt that it would be possible to rule all aspects of various conditions that any of us have, including Yahoo, in terms of genetics, which kind of seem to suggest that there is nothing that we did or that we could have done to have had improved our situation, whether it is clean lifestyle in terms of eating, sleep and exercise or whether there might have been some things that doctors could have done in terms of detecting issue, medicines and or surgeries in order to nip the situation in the bud or to perhaps mitigate aspects of the problem getting worse.

I would think that with something like the heart, if possible, we would prefer to live with our original parts, even if there may well be some denigration of performance, and even if we might be suffering from less than 30% ejection fraction.. which can be quite detrimental to our lives and even cause us to not be able to do a lot of things that others can do.. and also that if our heart function (and ejection fraction) is so low, we may well be better served by making sure that we are more rigorous in following healthy living practices - even when any of us could have short periods of deviation from healthy living practices and those will likely not kill us but in the larger sense, we might be able to stave off deterioration in our condition.. or even possibly to improve some aspects of our condition (even if never really being able to get back to "normal") but some tradeoffs may well be preferable, such as keeping our original heart, if that is possible..

Yahoo had already described that his ability to keep his ejection fraction up to 30% was only for a limited time, and largely it is seeming that he is not even able to keep his ejection fraction above 20% on his own with whatever he is doing - so it becomes almost impossible to imagine being able to survive for very long when unable to keep or maintain left ventricle ejection fraction at those kinds of already hampered levels.
