I recently had a Calcium Scoring Screening mainly because I have been experiencing some shortnes of breath and "heaviness" in my chest mainly when lying down. Total score came back at 306 with almost all in the left anterior. My cholesterol is only slightly elevated so my doc said the problem is mainly genetic. He gave me a prescription for Simvastatin. After researching and reading a lot of users comments about the side effects, I don't know if I want to start taking it. I also realize that people usually only post on the net when their experience is a negative one.
