Several non-invasive diagnostic imaging modalities are available for its evaluation, including coronary calcium score (CS), coronary CT angiography (AngioCT) and positron emission tomography with rubidium ( 82 Rb PET-CT), with excellent sensitivity and specificity. The integration of these methods into a hybrid examination allows delineating the anatomical and functional impact of atherosclerosis, enabling more accurate diagnoses. Objective: To evaluate coronary anatomy and myocardial perfusion of patients with suspected or known CAD with hybrid technology ( 82 Rb PET-CT and AngioCT/CS), testing the hypothesis of the greater accuracy of the hybrid method in relation to the isolated methods, correlating with myocardial infarction/cardiac death outcome after 24 months. Methods: Fifty-four consecutive patients referred from the Cardiology outpatient clinics of the Heart Institute (InCor-HCFMUSP) to perform CAD assessment in a hybrid study in the Department of Nuclear Medicine of InCor, between May and October 2013, were enrolled. The coronary atherosclerotic burden was accounted by CS; the amount of coronary lesions, stenosis severity and plaque composition were evaluated through AngioCT; 82 Rb PET-CT perfusional analysis was evaluated through the rest and dipyridamole stress summed difference score (SDS) and the coronary flow reserve (CFR) was considered impaired when < 2mL/min/g. After 24 months, the composite outcome of my...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
