Thanks for the good article on heart attack,Iread that also oxygen and morphine are parts of treating infarction. I am quiring the role of calcium and thyroid hormones.???????.it seems you mean calcium channel blockers not calcium per se.and no role for thyroid hormones .there is a tablet called angiotensin converting enzyme inhibitor which proved to be useful in heart failure. thanks alot for your goog information..Are you a
