I had a mild heart attack in 2005 and was told when they did a heart cath that there are no blockages
and that my MI was probably due to coronary
spasm. I have been hospitalized repeatedly since the heart attack and have tried all the usual medications such as verapamil, cardizem, imdur, metoprolol, lisinopril, norvasc and magnesium. I do not tolerate cardizem or imdur well. The angina was not controlled until they started me on Ranexa last year because the pain was constant and severe.
