Furthermore, patients with IHD (n = 66) had markedly elevated CCL21 compared to patients with DCM (n = 84) (747±66 pg/mL versus 494±46 pg/mL, p = 0.001), and notably, an opposite pattern was seen for CCL19 with the highest levels in DCM (129±10 pg/mL versus 154±97 pg/mL, p = 0.05). This evidence concerns the gene CCL21 and myocardial ischemia.
