Background: The usual diagnostic work-up of chest pain patients includes clinical risk profiling and exercise-ECG, possibly followed by additional tests. Recently cardiac computed tomographic angiography (CCTA) has been employed. We evaluated the prognostic value of the combined use of exercise-ECG and CCTA for the development of cardiovascular endpoints. Methods: In 283 patients (143 male, mean age 54 +/- 10 years) with intermediate pre-test probability for coronary artery disease presenting with stable chest pain, exercise-ECG, CCTA and calcium score were performed. Patients were followed-up for combined endpoint of acute coronary syndrome (ACS) and revascularization. Results: After a median follow-up of 769 days (interquartile range 644-1007), 6 ACS and 9 revascularizations were recorded. A positive exercise-ECG predicted for the combined endpoint, [hazard ratio (HR) 5.14 (95% confidence interval (CI) 1.64-16.13), p = 0.005], as well as a positive calcium score [HR 4.59 (95% CI 1.30-16.28), p = 0.02] and a >= 50% stenosis on CCTA [HR 45.82 (95% CI 6.02-348.54), p
