CVON HBC-crossroads programme

The new CVON HBC-crossroads (HBCx) programme further builds on the central hypothesis that hemodynamic

changes are an important and potentially reversible cause of VCI, now taking a more multidimensional (i.e.

crossroads) approach to hemodynamics, also addressing flow regulation and variability and factors that

modulate the impact of hemodynamic disturbances in VCI.

We will evaluate the role of hemodynamics in VCI in:

● key cardiac conditions (atrial fibrillation, valvular disease, heart failure/venous congestion)

● vascular factors (blood pressure variability, vascular reactivity, endothelial (dys)function)

● the primary cerebral co-morbidity of VCI, amyloid pathology (i.e. assess interplay hemodynamics and

amyloid)

We will also address age, sex, and environment as modulating factors.

Our ambitions are to identify treatable targets, further improve the diagnostic protocols and analyses, translate

research tools to diagnostic applications, and provide integrated heart-brain care for patients.

The framework of HBCx includes mechanistic studies, proof of concept treatment studies targeting

hemodynamics, and the implementation of the HBC concept in heart-brain clinics in daily care. We will build

on the rich HBC1 dataset, refine the analyses and will also establish new cohorts and link up with other existing

cohort studies such as RACE-V. We foster our young talents, connect with other research consortia and

industrial partners, and involve patients and clinicians.
