"Is curing patients a sustainable business model?"

No, obviously not.
The better question is: "Should health care be left to capitalism?"
Capitalism is driven by profit over ethics. So the answer is again: no obviously not.
Any area where ethics should supersede profits, should not be run by capitalism... obviously.
Now keep that in mind next time you get to vote please. If you're still that lucky.
