title: Analysis of coronary calcifications versus Framingham and PROCAM risk assessment in patients with a first myocardial infarction.
abstract: We compared the extent of coronary calcifications as quantified by electron beam tomography (EBT) to the predicted 10-year cardiovascular event risk based on Framingham and PROCAM algorithms in patients with a first myocardial infarction (MI).
  
  
  METHODS
  In 156 patients (56.7 +/- 22 years), EBT was performed <4 weeks after MI. Coronary calcifications were quantified using the "Agatston Score" and age-related calcium percentiles were determined. The predicted 10-year event risk was determined using Framingham and PROCAM algorithms.
  
  
  RESULTS
  Coronary calcifications were present in 148 patients with a mean "Agatston Score" of 589.2 +/- 976. The "Agatston Score" was >400 in 44% and >90th percentile in 42% of the patients. Framingham risk was >20% in 32% and PROCAM risk was >20% in 28%.
  
  
  CONCLUSIONS
  Coronary calcifications were detected in the vast majority of patients with a first MI, independent from the patient's age. The determination of age-related percentiles was superior to the Framingham or PROCAM algorithm.
