The study employed comprehensive multi-omics approaches including single-cell RNA sequencing and proteomics to identify the primary mechanisms: attenuated cardiac and hepatic fibrosis and reverse lipid transport. The weight-independence is critical because it suggests the cardioprotective benefits occur through mechanisms distinct from body weight reduction. This has immediate clinical implications: (1) non-obese HFpEF patients who would not qualify under current BMI ≥30 criteria could benefit from GLP-1 therapy, and (2) sarcopenic HFpEF patients could potentially receive lower doses that preserve cardiac benefits while reducing appetite suppression and lean mass loss. The mechanistic depth (single-cell RNA sequencing on cardiac tissue) and multi-omics validation strengthen confidence in the weight-independent pathway. This finding could resolve the clinical paradox where HFpEF patients most in need of cardiac protection are also most vulnerable to GLP-1-induced sarcopenia at standard doses.
