Hi Guys, I'm new to the thread. I'm 56 and workout every day, having done major triathlons and crossfit, now just a gym rat with low body fat, eat well and hardly drink. Just had a CT scan yesterday and a 2,854 CAC score plus a 4.3cm Ascending Aortic Thoracic Aneurysm (AATA). I do have pectus excavatum (indenting of the chest) a birth defect that I've always considered a badge of honor but it does affect normal heart function / circulatory function. But f**k them if they can't take a joke. Dr. ordered a stress test and an echo. I'm thinking the CAC score is helpful but doesn't tell the whole picture. CAC with AATA is a bit disconcerting but I'm also hoping it can all just be managed. PS, I love weight lifting and running high intensity, both blood pressure inducing. Wondering if anyone feels the same.
