Figure 4 CTA Event-Free Survival

Risk-adjusted event-free survival by computed tomographic angiography (CTA)-diagnosed coronary artery disease (CAD) stratified by severity of disease and number of diseased coronary arteries. Risk adjustment included the following variables: age, gender, hypercholesterolemia, diabetes mellitus, smoking, hypertension, family history of premature coronary heart disease, and coronary artery calcium score. All-cause mortality increased significantly by increasing severity of CTA-diagnosed CAD and number of diseased coronary arteries.
