Patients in the IHD group presented a significantly higher concentration of IGFBP7 than those in the population group (1.76 ± 1 ng/mL vs. 1.43 ± 0.44 ng/mL, respectively, p = 0.019), as well as a significantly higher concentration of creatinine, urea, glucose, insulin, TnT and NTproBNP (detailed characteristics of the studied group are presented in Table 1). The gene discussed is INS; the disease is myocardial ischemia.
