Validation/Evaluation of Multimodal Imaging Combining 3D Ultrasound and Stress Myocardial Scintigraphy in the Diagnosis of Coronary Artery Disease

Validation and Evaluation of Multimodal Imaging Combining Three-dimensional Ultrasound and Stress Myocardial Scintigraphy in the Diagnosis of Coronary Artery Disease

Our primary goal is to validate a new diagnostic tool for functional coronary artery stenosis that uses multimodal imaging (combining stress echocardiography and stress scintigraphy) in patients with known coronary chest pain.

Inclusion Criteria:

• The patient must have given his/her informed and signed consent
• The patient must be insured or beneficiary of a health insurance plan

Exclusion Criteria:

• The patient is participating in another study
• The patient is in an exclusion period determined by a previous study
• The patient is under judicial protection, under tutorship or curatorship
• The patient refuses to sign the consent
• It is impossible to correctly inform the patient
• The patient is pregnant
• The patient is breastfeeding
• Patients with arrhythmias, left bundle branch block on the electrocardiogram which would complicate the interpretation of examinations
• Unstable, acute coronary syndromes unstable needing emergency coronary angiography

• poorly controlled hypertension
• pre-existing severe arrhythmia
