I've had eec but i don't think i improved much. what other treatment options are available?

R u on max meds?: If you are on a maximal medical program such as nitrates , beta blockers and anti platelets and your already on the newer agent Ranexa (ranolazine) then eecp is a nice option . If no other revascularization options are available such as angioplasty or bypass then( if a candidate qualifies) then transplant may be an option for refractory angina.

EECP?: I assume you mean external counter-pulsation? If you're maxed out on medication and not a candidate for further revascularization, either percutaneously or by surgery, than there's no other treatment except transplant.
