The reduction of RBP4 in the blood circulation was also found in other pathological conditions such as acute myocardial infarction, ischemic heart disease, cholesterol gallstones, stroke, liver disease, and type I diabetes (Bahr et al., 2009[5]; Cubedo et al., 2014[13]; Pullakhandam et al., 2012[31]; Wang et al., 2010[38]). This evidence concerns the gene RBP4 and myocardial infarction.
