In vivo models for heart failure research

Area of Science:

• Cardiology
• Translational Medicine
• Animal Models

Background:

• Heart failure (HF) presents a significant mortality challenge, with a 5-year survival rate of only 50% despite medical treatment.
• Effective therapies for HF necessitate a deep understanding of its underlying pathophysiology.
• Animal models are indispensable tools for advancing HF research and developing novel therapeutic strategies.

Purpose of the Study:

• To review common in vivo animal models used in cardiology research, specifically for studying heart failure (HF) remodeling.
• To highlight the critical role of animal models in evaluating new HF treatments, including gene therapy, mechanical devices, and surgical approaches.
• To emphasize the importance of considering species, strain, and gender when selecting and utilizing animal models in HF research.

Main Methods:

• Review of existing literature on in vivo animal models for heart failure (HF) research.
• Analysis of the advantages and limitations of various animal models in the context of HF pathophysiology and remodeling.
• Discussion of factors influencing model suitability, including technical determinants, species, strain, and gender.

Main Results:

• Identified common in vivo models utilized in cardiology for studying heart failure (HF) remodeling.
• Acknowledged that no single animal model is universally suitable for all aspects of HF research.
• Highlighted the impact of species, strain, and gender on HF pathogenesis within animal models.

Conclusions:

• The selection of appropriate animal models is essential for advancing the understanding and treatment of heart failure (HF).
• Careful consideration of model-specific factors (species, strain, gender) is critical for accurate and reproducible research outcomes in HF.
• Continued development and refinement of in vivo HF models are vital for the evaluation of innovative therapeutic interventions.
