After a heart attack a few years ago my cholesterol (total --hdl+ldl is about 102, bp -- 115/60 --, and cardio conditioning as measured by repeated stress tests indicated no apparent problems. I exercised regularly, and then had another event happened this past winter. A few more stents later I know this can and probably will happen again. I asked my cardiologist about the positive stress tests, etc...., and he replied that a stress test is only as good as the moment you take it, so it is not necessarily an indication that all is well.
I started cycling recently as a way to do what I can do to have good cardio conditioning and hope that what ever happens in the future will be mitigated by the cycling and other exercise and diet.
Good luck!
