Am I interpreting my CT angio score correctly?

Had a CT calcium scan & since I live out of town, results were sent to me. Family history of coronary artery disease. See Coronary Doctor this coming Wednesday, but need to know. Everything I read says it is not good. Score was 880, top 90 percentile. Am I interpreting it correctly?

CT Angio for coronaries only tells you exactly what you see – calcium. Everything needs a clinical correlation which your doctor should provide.
