Clinical Trial Summary

The effect of brain-heart interaction remains unclear. The study aims to investigate the biological interconnection between brain neural activity and coronary plaque morphological and inflammatory features, as well as their connection with clinical outcomes.


Clinical Trial Description

Brain neural activity assessed by resting amygdalar activity (AmygA) can predict cardiovascular events. However, its biological interconnection with plaque vulnerability i is not fully understood. Coronary computed tomographic angiography (CCTA) is a non-invasive technique that enables comprehensive assessment of morphological characteristics of coronary atheroma and estimates the level of plaque instability. Recently, perivascular fat attenuation index (FAI) enables assessment of coronary inflammation by analyzing changes of perivascular adipose tissue attenuation in CCTA. 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT) enables simultaneous estimation of multi-system activities including brain neural activity and hematopoiesis. The present study aims to use ¹⁸F-FDG PET/CT to assess the AmygA, and to investigate its association with CCTA assessed plaque morphological and inflammatory features as well as their ability in predicting future cardiovascular disease events. ;
