The use of large animals in research provides a unique bridge between preclinical findings and clinical relevance, offering a valuable perspective for advancing our understanding of the complexities of heart failure. Multiple models of heart failure have been established with advantages and limitations of each model. Many insights have been gained from these models for understanding both pathophysiological mechanisms and therapeutic interventions for heart failure.
