Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate image quality of coronary CT angiography (cCTA) after sublingual and transdermal administration of Nitroglycerin. Aim of this prospective research study is to investigate equivalence on image quality after sublingual or transdermal Nitroglycerin administration (H0).

Furthermore, the feasibility of transdermal Nitroglycerin administration will be evaluated.

Sublingual Nitroglycerin spray

Sublingual Nitroglycerin spray of 0.8 mg

Group Type ACTIVE_COMPARATOR

Nitroglycerin

Intervention Type DRUG

Patients grouped in sublingual administration (group 1 and 2) will receive Nitroglycerin during the cCTA scan by the MD after the Calcium scoring scan and 5 minutes before the actual cCTA scan. Patients categorized to transdermal administration will receive Nitroglycerin 1 hour before the CT examination. The patch will be placed on the chest or the upper arm.
