Clinical Trial Summary

SUSPECT is a prospective, single-center, cohort study of 250 military aircrew at the Center for Man in Aviation, Royal Netherlands Air Force. All asymptomatic aircrew (≥40 years) are asked to undergo a coronary CT scan on a voluntary basis, following the exercise electrocardiograms performed at their routine aeromedical examination. Coronary Artery Calcium score (CACS) and CCTA findings are reported.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Determine the prevalence and severity of CAD in asymptomatic air crew using CCTA as a primary screening tool		8 Years
Secondary	Determine the diagnostic accuracy of clinically relevant CAD of the exercise stress test versus CCTA	Both modalities are used to track down clinically relevant CAD. Clinically relevant CAD is defined as a stenosis of >50%.	8 Years
Secondary	Compare the incidence of Major Adverse Cardiac Events (MACE) and all-cause mortality in populations screened between primary and secondary screening after 12 months		8 Years
Secondary	Compare the incidence of coronary angiograms and revascularization procedures in the population screened with CTA compared to a historical population using CTA as a secondary screening tool		8 Years
Secondary	Establish the additive value of coronary artery calcium score (CACS) in addition to clinical risk scores as a predictor of CAD on CCTA		8 Years
