Heart failure (HF), the terminal state of different heart diseases, imposed a significant health care burden worldwide. It is the last battlefield in dealing with cardiovascular diseases. HF with preserved ejection fraction (HFpEF) is a type of HF in which the symptoms and signs of HF are mainly ascribed to diastolic dysfunction of left ventricle, whereas systolic function is normal or near-normal. Compared to HF with reduced ejection fraction (HFrEF), the diagnosis and treatment of HFpEF have made limited progress, partly due to the lack of suitable animal models for translational studies in the past. Given metabolic disturbance and inflammatory burden contribute to HFpEF pathogenesis, recent years have witnessed emerging studies focusing on construction of animal models with HFpEF phenotype by mimicking metabolic disorders. These models prefer to recapitulate the metabolic disorders and endothelial dysfunction, leading to the more detailed understanding of the entity. In this review, we summarize the currently available animal models of HFpEF with metabolic disorders, as well as their advantages and disadvantages as tools for translational studies.
心力衰竭(HF)是不同心脏病的终末期状态,在全球范围内造成了沉重的医疗负担。它是心血管疾病治疗的最后战场。射血分数保留的心力衰竭(HFpEF)是一种心力衰竭,其心力衰竭的症状和体征主要归因于左心室舒张功能障碍,而收缩功能正常或接近正常。与射血分数降低的心力衰竭(HFrEF)相比,HFpEF的诊断和治疗进展有限,部分原因是过去缺乏适合转化研究的动物模型。鉴于代谢紊乱和炎症负担促成了HFpEF的发病机制,近年来出现了一些研究,专注于通过模拟代谢紊乱构建具有HFpEF表型的动物模型。这些模型倾向于重现代谢紊乱和内皮功能障碍,从而更详细地了解该疾病实体。在这篇综述中,我们总结了目前可用的伴有代谢紊乱的HFpEF动物模型,以及它们作为转化研究工具的优缺点。
