Overview

Randomized trial finds clonal hematopoiesis increases aortic valve calcification risk, suggesting a potential therapeutic target.

Key Points

This research investigates the role of clonal hematopoiesis in the development of aortic valve stenosis.
Meta-analysis of patients from All of Us, BioVU, and UK Biobank
Single-cell RNA sequencing of immune cells from patients with AVS and TET2 mutations
In vitro calcium deposition assays using TET2-silenced macrophages and mesenchymal cells
Patients with clonal hematopoiesis had a higher risk of aortic valve stenosis, especially with TET2 or ASXL1 mutations
Increased expression of procalcific factors like oncostatin M in macrophages with TET2 mutations
Ldlr-/- mice with Tet2-/- bone marrow transplants showed greater calcium deposition in aortic valves
