射血分数保留的高脂血症诱导心力衰竭小鼠模型

Executive Industry Relevance

Hyperlipidemia-induced murine models of HFpEF provide a translational platform for dissecting the metabolic and lipotoxic drivers of diastolic dysfunction. This model enables mechanistic de-risking and target validation for cardiometabolic pathways implicated in heart failure with preserved ejection fraction. Its predictive value supports early-stage portfolio decisions and informs preclinical strategy for metabolic syndrome-related cardiac disease.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables interrogation of lipotoxicity and metabolic syndrome as drivers of HFpEF pathogenesis.
• Supports functional target validation for lipid handling and cardiac metabolism pathways.
• Facilitates mechanistic de-risking by modeling human-relevant cardiac phenotypes.
• Provides a platform for hypothesis testing on metabolic and inflammatory contributors to HFpEF.

Screening & Assay Development

• Establishes a validated in vivo system for quantitative assessment of cardiac function and metabolic biomarkers.
• Supports reproducible measurement of diastolic dysfunction and preserved ejection fraction via echocardiography.
• Enables standardized evaluation of candidate interventions targeting lipid metabolism and cardiac remodeling.
• Prepares the groundwork for scalable compound screening in disease-relevant models.

Translational & Preclinical Research

• Aligns with disease-relevant endpoints such as fibrosis, cardiac ischemia, and sudden death observed in HFpEF patients.
• Provides continuity from discovery to preclinical validation for metabolic and inflammatory targets.
• Supports risk-adjusted advancement of therapeutic candidates addressing lipotoxicity-driven cardiac dysfunction.
• Facilitates biomarker alignment for translational studies in larger animal models.
