I just had a stent put in my right coronary arteries, in reading the report it says , when they in flared the balloon up to 9atmospheres for 30 sec. The patient had chest pain when it was inflated it , it disappeared when it was deflated no Moore EKGchanges. There was spasm prier to the stent in the first marginal branch. After 200 mcg fo Nitroglycerin the spasm in the superior artery appeared normal in appearance with 0% residual stenosis
