Blueprint: Brain-heart Interaction in Coronary Plaque Stability and Cardiovascular Events
Study Details
Study Description
Brief 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.

Detailed 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.

Outcome Measures
Primary Outcome Measures
- Correlation Between amygdalar activity (neurobiological activity) and bone marrow hematopoiesis (hematopoietic activity) [at the index imaging]
Amygdalar target-to-background ratio (TBR) = Amygdalar standardized uptake value (SUV) / Temporal lobe SUV Bone marrow TBR = Bone marrow SUV / Jugular vein SUV Correlation between amygdalar activity (neurobiological activity) and bone marrow hematopoiesis (hematopoietic activity) will be assessed
- Correlation Between amygdalar activity (neurobiological activity) and high-risk plaque [at the index imaging]
High-risk plaque features will be assessed by CCTA including positive remodeling (PR, defined as lesion diameter/reference diameter ≥1.1), low attenuation plaque (LAP, defined as a focal central area of plaque with an attenuation density of <30 Hounsfield Units), spotty calcification (SC, defined as focal calcification within the coronary artery wall <3mm in maximum diameter), and the "napkin ring" sign (defined as a central area of low attenuation plaque that had a peripheral rim of high attenuation). Correlation Between amygdalar activity and number of high-risk plaque features will be assessed.
- Correlation Between amygdalar activity (neurobiological activity) and coronary inflammation [at the index imaging]
Coronary inflammation will be assessed by FAI. Correlation Between amygdalar activity and FAI will be assessed
- Major adverse cardiac events [5 years after index imaging]
Death from coronary heart disease, nonfatal myocardial infarction or hospitalization for unstable angina.
Secondary Outcome Measures
- Cardiovascular death, or nonfatal myocardial infarction [5 years after index imaging]
Cardiovascular death, or nonfatal myocardial infarction
