Calcium scoring results indicate the amount of plaque present in the coronary arteries. A score of zero means no disease, no identifiable plaque, and a very low risk of a coronary event, with a retest recommended in five years. The range of 1 to 99 reflects early-stage disease with minimal plaque, and patients in this category should follow up with their primary care physician. Results between 100 and 399 indicate early-stage disease with moderate plaque, and mild coronary artery disease is highly likely, while readings of 400 or higher signal advanced disease and may require a same-day visit if the score reaches 1000. These categories help patients understand their results so they can discuss next steps with their doctor.
