Tiny vsd.cardiac workup shows possible past heart attack.having heart cath 4 constant chest pressure/shortness of breath.possible discomfort causes?

Chest pain not from : Chest pain possibly from ASHD or blocked coronary arteries. What showed possible old heart attack if this was an ekg this is not that accurate. If it was and echocardiogram or cardiac sonogram that showed prior heart muscle damage that is probable accurate. Cardiac cath should tell you if you have blocked arteries and how significant they are. If borderline blockages are found a wire can be passed.
