From the Mayo Clinic web site:
A score of zero means no calcium is present in the heart and suggests a low likelihood to develop a heart attack in the future. When calcium is present, the higher the score, the higher the risk of attacks in the long term. A score of 100 to 300 — moderate plaque deposition — is associated with a relatively high risk of heart attack or other heart disease over the next three to five years. A score greater than 300 indicates very high to severe disease and heart attack risk.
