Implication
Randomized trial develops models predicting all-cause mortality in asymptomatic individuals, indicating the value of coronary calcium screening.
Key Points
- To assess the prognostic value of cardiac risk factors and coronary calcium scores for predicting all-cause mortality.
- Cohort of 10,377 asymptomatic individuals undergoing cardiac risk factor evaluation and coronary calcium screening.
- Risk-adjusted multivariable Cox proportional hazards models were developed.
- Follow-up duration averaged 5.0 years.
- Death rate was 2.4% during follow-up.
- Coronary calcium scores were independently predictive of mortality (P <.001).
- Five-year survival was 99.0% for scores of 10 or less vs. 95.0% for scores greater than 1,000 (P <.001).
