We've made a lot of progress in the diagnosis and treatment of heart disease, but Coronary Calcium Scores remain a wild card. I read an article recently that suggested that suggested that lifelong athletes tend to have higher CAC, but that it resides inside the artery wall so doesn't block blood flow. Who knows? There seem to be so many variables to calcium buildup, like location, dense vs spotty, soft vs hard, vessel size, collateral circulation, etc.
Bluesdoc hit the nail on the head with surgical precision by saying that we all need to chill and do our best to prevent a heart attack. As an aside, I read a book, "Heart: A History" by the cardiologist Sandeep Jauhar, that I recommend. He mentions in the book that he has a high CAC score and an increased risk due to his family history and South Asian ethnicity.
