Expert discussions with Dr. Campbell Rogers
Can a scan show whether your heart plaque is growing or shrinking?
A CT scan plus computer analysis can now measure how much plaque is in your heart arteries, and what it is made of, rather than estimating your risk from blood markers. Many people who have a heart attack had no warning symptoms beforehand, and a calcium score of zero cannot see soft plaque at all. The headline claim of a 48% reduction over 16 months is less solid than it sounds: two other analysis tools read the same scans and disagreed, including on the direction.
