Dear Suzanne, thank you for your question. Coronary spasm is a difficult disorder to diagnose and to treat. The catheter used to do the cardiac cath can irritate the coronary artery and can cause spasm that is iatrogenic. Then, there are patients with true coronary spasm who never have spasm during the cath. However, I presume that you have no evident coronary artery stenoses on your cath. Spasm is usually treated with calcium channel blockers (Diltiazem, Norvasc, etc.) and nitrates. If these medications haven't worked for you, I'm not sure what else would. If you are having frequent PVC's, then a beta blocker may help but you already may have tried that. Also, common precipitants of PVC's (alcohol, tobacco, and caffeine) should be avoided. It sounds like your condition is quite complicated so it might help for you to get a second opinion at a tertiary medical center. Otherwise, it's difficult for me to comment on your condition in this forum since I'm unable to make diagnoses and we are only able to give general information. Good luck!
