It is relevant in exactly the way that I said: we would be going broke more slowly, because we would be spending less on health care.

However, to address your question directly, look at debt to GDP ratios:

The US is in the middle of the pack. Countries with more sane health care systems and better levels of debt include Ireland, the Netherlands, Spain, Germany, Finland, Denmark, Canada, Sweden, and Australia. I don't see any reason to believe that they're being driven bankrupt by their health care systems.
