I have confirmed Coronary Artery Spasm(CAS also know as Prinzmetal, variant angina) at Mayo with heart cath with intracoronary acetylcholine. I reporduced multiple vessels one one of the caths no EKG changes at all but the flow deviations was apparent. First see if you can determine your triggers. Some that are often triggers are chocolate, coffee, cold, hypoxia, hypertension, hypotension. Tachycardia & bradycardia. I also trigger with Dicyclomine, Nebivolol(Bystolic), Methacholine,ergonivine. When I have an attack they have me break a capsule of Nifedipine under my tongue, do 3 nitel sprays if keeps coming back then follw with another Nifedipine if BP over 100. If that does not work I have to go to Emergency for Nitro drip. Riht now I have sever hypoxia so I fight stayiing outof ER all day & Night it is 1:49 am my time & am sitting her taking the meds for it. I haave treachoBonchoplasy 22nd to correct the hypoxia. Then we wil try to get me back off this horrible routine of meds I am on.
Here is my med regime trying to get me to the 22nd to saty or of ER
6 am Imdur 120, Nicardipine 60, omeprazole, L-arginine
before I get out of bed Nitro spray & isosorbide dinitrate 20
10 am Verapamil , Diltiaziam 120, POTASSIUM , pyridoxine, multivitamin, magnesium, Prednisone
2 pm niCARdipine 60, Imdur 30 L-arginine (if BP running lower 50 Nacradipine instead of 60)
10 pm isosorbide dinitrate 40,, niCARdipine 50
The meds are all aimed at stopping the Spasm or slowingmy heart down because I have Tachycardia as well. Now I am the only patient they have had to throw all these at. At 41 Cardizem (diltiazem) held me for years. Then I started having issues 2010 and they switched me to Verapimil. that worked until 2012 when thye hypoxia & tachycardia took off. MY EKG when no spams is 100% normal. During spasms I no loner get high ST sue to be on all the meds. They see ST invert then swithc back, ST flatten,it will indicate variious past MI's, heat blocks of variosu kinds etc. all thes eare indicative of Ischemia. Does your nitro lessen the pain at all? Mine the pain goes down soem then wil come back up. At tiems I have beeen in ICU up to 1 week on NIRO drip at 65 to keep me pain free until it calmed down enough to take me off the drip. As the spams saty spasming the worse the endothelial dysfunction gets. Yhe L-argien is an over the counter supplement that can help the endothelial dysfunction which is what causes the Spasms.
