Vitamin B6 prevents heart failure with preserved ejection fraction through downstream of kinase 3 in a mouse model

There is an urgent need to develop an efficient therapeutic strategy for heart failure with preserved ejection fraction (HFpEF), which is mediated by phenotypic changes in cardiac macrophages. We previously reported that vitamin B6 (VB6) inhibits macrophage-mediated inflammasome activation OBJECTIVE: We sought to examine whether the prophylactic use of VB6 prevents HFpEF METHODS: HFpEF model was elicited by a combination of high fat diet and N
