Both the total number of CD68(+) macrophages and the number of CD68(+) cells directly adhered correlated negatively with cTnT in the serum of DCM patients (Spearman’s rho, r = −0.45, P < 0.001 and r = −0.31, P = 0.009, respectively). The gene discussed is CD68; the disease is familial dilated cardiomyopathy.
