Hi. I am a 61 year old male. Thought i would relate my experience in the interest of information. About a year ago, I had a small episode of dizziness after a 3 mile exercise walk. Lasted about 30 seconds, but since i hadn't seen my general practitioner for a while, I decided to consult him. I was given a bank of exams including ultrasound, scans, and a stress test. ALL were negative for problems. My general practitioner, I feel, saved my life by saying he wasn't yet satisfied that my experience was a fluke. I was sent to have what is called a "calcium score", which, by the way, isn't covered by my insurance. A normal calcium score is in the 400 range. Mine was over 900. A definitive angiogram was ordered. The angiogram revealed serious blockages at the anterior and posterior areas of my heart. They required 7 1/2 stents. My cardiologist remarked that i was a heart attack waiting to happen. Given the fact that ALL of my previous tests were negative, and the calcium score was the only red flag, I find it interesting that this procedure isn't a normal routine exam. It isn't really expensive either. Mine was 99 dollars, and i understand that they can range up to 300 dollars. I hope this information is useful. Thanks.
