The CT Scan came back with this assessment:

Total coronary calcium score is 330. Total calcium volume is 265. Total number of coronary artery calcifications is 5. For a Male patient aged 74 years, this corresponds to between the 50th and 75th percentile, that is, 25% of patients this age have a higher score. By Rumberger criteria, this corresponds to a moderately high cardiovascular risk. 

Still waiting to hear from my cardiologist.
