If he has heart problems, then he should be focusing on his health, a solid support system including a healthy relationship with his GF.
Instead, he is choosing to destroy the sanctity of his relationship and go stick his dick wherever he can, adding more chaos, blaming you for it, etc. etc.
Tell him to enjoy his heart attack and you might even put a daisy you picked on the side of the road on his grave when the time comes. Also, tell him you hope his whore has good insurance, which being a poacher of another woman's man likely has nothing of value to offer except her spread legs.
Sorry you are going through this. Don't let the bullshit excuses and blame shifting typical of cheaters get to you. Always step back and look at who absolutely LUDICROUS the things that come out of cheater's mouth truly are when you look at them from a distance.
Good luck to you!
