Animal models of preeclampsia are widely used to elucidate the underlying pathology and investigate the clinical utility of drugs. Although a large body of data has been generated that supports their usefulness, animal models are not necessarily suitable for all research objectives. A more thorough understanding of advantages and disadvantages of each animal model will facilitate selection of appropriate models for a given study area, thereby enabling researchers to obtain more useful research results. The metabolic domino theory offers an explanation for the time-course of increase in the risk of cardiovascular events due to complex interactions among lifestyle-related diseases, which is likened to the sequential falling of dominoes. This theory provides a valuable perspective for understanding the importance of lifestyle-related diseases, as well as the process leading to the onset of cardiovascular events. Preeclampsia has adverse effects on both pregnant women and their fetuses/infants in the short term, whereas in the long term, it also increases the frequency of cardiovascular events in patients approaching middle and old age. Therefore, from a clinical perspective, preeclampsia is considered similar to lifestyle-related diseases, and its pathology might be better understood in light of the metabolic domino theory; this, in turn, will facilitate the selection of an appropriate animal model. Various models are considered applicable for research aimed at elucidating the pathology of preeclampsia, including antiangiogenic factor overexpression models, reduced uterine perfusion pressure (RUPP) models, and risk-and regulatory-factor knock-out models. However, in light of the metabolic domino theory, these models do not accurately replicate the pathology of preeclampsia, and are thus not necessarily appropriate for the investigation of drug utility.
