Is a catheteriization necessary

I am 48 year old female, have had high cholestrol for which I have been on Zetia & Tricor for several years, now is almost normal. I had a bad reaction to the statins- ended up in the hospital with very high liver enzymes.  Recently, I have been getting very lightheaded and experiencing pain in my upper arms. My doctor refered me to a cardiologist who performed the heart ultrasound and the holter which came back normal. The stress test however was abnormal- 1 millimeter st segment depression.  My cardiologist would like to a heart cathetrization and possibly insert stents.  Is this appropriate for a 1 millimeter difference?

A 64 slice CT scan can produce an excellent image of your coronary arteries.  It is almost as good as an angiogram, noninvasive, and a whole lot cheaper.
