If you were able to fix or prevent the kind of mollecular damage that Grey mostly talks about when he talks about aging, it would probably reduce your odds of getting a heart attack in any given year, but I'm not convinced that it would eliminate it. After all, some people do get heart attacks when they're 30, it's just more rare.
Which means that for extreme longevity you would probably have to still find better ways to deal with, cure, or prevent heart attacks, even if we've already "cured aging" by the narrow definition of aging you seem to be using.
Also, in a related note, if we're talking about "longevity escape velocity" (the point where science and technology adds 1 year of lifespan for each year that passes, making it possible for you to live indefinitely), anything that treats any of the diseases of aging would help with that. Right now, heart attack and cancer are the two big killers in the first world; cure either of those, and you've extended lifespan by several years already.

Yes, of course. "Curing aging" by itself does little to help with a variety of fatal diseases. People who don't age will still die from infections, strokes, etc. etc.
Google's announcement, Time magazine rather sensationalist headline.
In any case, it's nice to know that Google set its sights to "challenge ... aging and associated diseases". Apple's Tim Cook:
For too many of our friends and family, life has been cut short or the quality of their life is too often lacking. Art is one of the crazy ones who thinks it doesn’t have to be this way.
One more step towards "world optimization".
