My husband had a heart attack when he was 26!
But his symptoms were different to yours,
He had really bad central crushing chest pain that would not go away,and he looked grey in the face!
I stress that this is rare, so don't worry!
Also why would your husband use your weakness against you?
I don't know him but it sounds like he needs a good talking to!!
You need support, not hubby making you feel worse!
Keep your chin up!
