Ask the doctor: Are there radiation-free tests for checking my arteries?

Are there any noninvasive, radiation-free tests that can give the same information about possible blockages in my coronary arteries as a nuclear stress test? I’ve had so many CT scans for other conditions that I’d prefer to go non-nuclear for a while.

Ask the doctor: How could I have a heart attack after a normal exercise test?

I had a nuclear exercise test last fall, and it was perfectly normal. Imagine my surprise this spring when I developed burning chest pain that turned out to be a heart attack on the bottom part of my heart. Did the doctors mess up the reading of my test?

Ask the doctor: How did my blood pressure suddenly become normal?

I was taking diltiazem and Atacand, which gave me an average blood pressure of 110/65. Recently while in the hospital, my blood pressure got so low I was told to stop taking these medications. My blood pressure has remained at 105/65. How can this be?
