By comparison, we revealed that the latter was characterized by younger age, higher BMI, higher rate of MI, but lower DM and AF incidence, a higher iron deficiency rate, higher hemoglobin and lower SCr levels, lower FBG, TyG index, NT-proBNP, UA, LVEF, and E/e values, and higher administration rates of ACEI/ARB, beta-blockers, and aldosterone receptor blockers. Here, NR3C2 is linked to Iron deficiency anemia.
