Overview

Retrospective analysis links hematopoietic JAK2V617F mutation to increased atrial fibrillation risk, highlighting macrophage inflammation role and ruxolitinib's potential benefits.

Key Points

This research explores how the hematopoietic JAK2V617F mutation is linked to atrial fibrillation (AF), focusing on the role of inflammation in macrophages.
Retrospective analysis of 1331 patients with myeloid malignancies using Fine-Gray multivariable models.
Development of JAK2V617F knock-in mouse model for in vivo and ex vivo studies.
Single-cell RNA sequencing of left atrial tissues to assess cellular phenotypes and interactions.
JAK2V617F mutation identified as an independent risk factor for new-onset AF (HR=2.20).
Mediation analysis showed IL-1β significantly mediates JAK2V617F's effect on AF.
JAK2V617F mice exhibited higher AF induction rates, enlarged left atria, and increased fibrosis versus wild-types.
