Perfusion myocardique à l'effort CT, réserve de débit fractionnaire et angiographie chez les patients présentant des syndromes de douleur thoracique stables (DYNAMITE)
DYnamic CT Stress PerfusioN myocardial, CT Fractional Flow Reserve et Coronary CT Angiography for Optimized Treatment Strategy Chez les patients présentant des syndromes de douleur thoracique stables
The purpose of the DYNAMITE trial (Dynamic CT stress myocardial perfusion, CT fractional flow reserve (FFR-CT) and coronary CT angiography for optimized treatment strategy in patients with chest pain syndromes) is to determine the ability of combined anatomical and functional cardiac CT imaging to improve morbidity and mortality in patients with suspected or known ischemic heart disease.

Description détaillée
Trial design
The DYNAMITE trial is an investigator-initiated, randomised controlled, open-labelled trial conducted in the Capital Region of Copenhagen, Denmark
The following hypothesis will be tested:
- First primary hypothesis: A treatment strategy guided by combined dynamic CT myocardial stress perfusion, FFR-CT and CT coronary angiography improves clinical outcome compared with a conventional management strategy in patients with chronic chest pain syndromes
- Second primary hypothesis: A treatment strategy guided by combined dynamic CT stress myocardial perfusion, FFR-CT and CT coronary angiography results in improved symptom relief compared with a conventional management strategy in patients with chronic chest pain syndromes

CT angiography, FFR-CT and dynamic CT stress myocardial perfusion guided treatment strategy |
The study intervention team consists of a specialist in Cardiac CT imaging, an invasive cardiologist, a thoracic surgeon and a cardiology nurse specialist. Treatment strategy defined by the study team based on CT findings involve referral for percutaneous coronary intervention, Coronary Artery Bypass surgery and/or initiation of optimal medical therapy, in addition to potential supplementary diagnostic procedures. |
