暴露于寒冷会促进心脏重塑,以对结构和功能的有害影响为特征,导致心血管疾病死亡率增加。与这些变化相关的机制知之甚少。这篇综述收集了与小鼠冷暴露引起的不良心脏结构和功能重塑相关的主要变化和机制的文献资料。原始研究是通过搜索PubMed确定的,Scopus,和Embase数据库从1990年1月到2022年6月。本系统评价是根据PRISMA制定的标准进行的,并在PROSPERO(CRD42022350637)中注册。偏倚风险由SYRCLE评估。合格的研究包括以英文发表的原始论文,这些论文评估了接受短期或长期冷暴露的小鼠的心脏结果,并在室温下进行了对照组。这篇评论中包含了17篇原创文章。冷暴露诱导病理性心脏重塑,以有害的结构和功能参数为特征,代谢和自噬过程的变化,氧化应激的增加,炎症,和凋亡。此外,Nppa,AT1A,Fbp3,BECN,ETA,而MT,似乎在调节心脏重塑中起着基本作用。我们建议,寻求将冷暴露的CVD风险和不利影响降至最低的策略应针对这些药物。
Exposure to cold promotes cardiac remodeling, characterized by deleterious effects on structure and function, contributing to increased mortality from cardiovascular diseases. The mechanisms associated with these changes are poorly understood. This
review gathers the literature data on the main alterations and mechanisms associated with the adverse cardiac structural and functional remodeling induced by cold exposure in mice. Original studies were identified by searching PubMed, Scopus, and Embase databases from January 1990 to June 2022. This systematic
review was conducted in accordance with the criteria established by PRISMA and registered in PROSPERO (CRD42022350637). The risk of bias was evaluated by the SYRCLE. Eligible studies included original papers published in English that evaluated cardiac outcomes in mice submitted to short- or long-time cold exposure and had a control group at room temperature. Seventeen original articles were included in this
review. Cold exposure induces pathological cardiac remodeling, characterized by detrimental structural and functional parameters, changes in metabolism and autophagy process, and increases in oxidative stress, inflammation, and apoptosis. In addition, Nppa, AT1A, Fbp3, BECN, ETA, and MT, appear to play fundamental roles in regulating cardiac remodeling. We suggest that strategies that seek to minimize the CVD risk and adverse effects of cold exposure should target these agents.
