  • Distribution of diagnostics and therapeutics during follow-up in patients with a CT-first strategy and the population without a CT-first strategy. Anatomical imaging comprises cardiac CT and coronary angiography. Perfusion imaging includes cardiac PET, SPECT and MRI. Coronary interventions are coronary artery bypass grafts and percutaneous coronary interventions.
