Chest Pain and Heart Arrhytmias

I have had 5 heart caths and 7 stents placed  starting Feb. 2005, 4 stents, July 2005, 2 stents,  Nov. 2006 ,(Non-Qwave myocardial Infarction) 1 stent. A blockage occured in a previously placed stent. I have heart arrhytmias and chest pain several times weekly. Had a cath done in Oct. 2007 and it was clear no blockage found. What could be causing the constant angina and heart palpitations? This really scares me and my family.

Sometimes when you have stents placed (you have had quite a few) small branches from the main blood vessels can get occluded and may cause angina even if the stent is open. You could also be having a fast heart rate from an "arrhythmia" a kind of electrical abnormality , discuss it with your cardiologist.

Since I do have 7 stents and am having angina attacks, I had a heart cath in Oct.07, heart was fine at that time , are these 100% accurate? My last visit to cardiolgist 4-16-08, I had an angina attack in the office visit and I am told I will need a stress test and I have taken these before and they showed nothing and 2 weeks later I'm rushed in emergency getting stents.Why did this not show on he stress test? They are very expensive. Thank you for your help! Jo
