Sounds like what you're describe is coronary vasospasm
(also known as vasospastic angina
, Printzmetal's angina) and is due to abrubt occlusion of the coronary artery from smooth muscle
cell contraction within the vessel wall- not blood clot formation as is the case in most MIs. The best treatment for this are nitrates (i.e. Imdur) and calcium channel blockers (i.e. Norvasc
) because they cause smooth muscle cell relaxtion/vasodilation
. Both are once daily, well-tolerated and quite effective. Ask you doctor for a script, if this is ifact what you have.
Your cardiac prognosis is quite good even if you have this condition as you didn't have an MI and you do not have coronary artery disease (if your angiogram was normal).
