very interesting. Now have some questions for my cardiologist. I am having a ct scan with contrast next week. Will be my second scan in last 6 months. I feel better about myself as i gain knowledge. I have cut my weight lifting to 20 pounds and do a lot of reps. Waiting for weather to improve so biking and gardening can begin. Last scan showed 4.8 even though three people read it and one said 4.0, the cardiologist said 4.2 and the surgeon said 4.8. They all measured differently. Now i wait for the next results. Ifeel knowledge helps to reduce anxiety and my BP.
