RESUMEN
Objective: To determine plasma levels of soluble tumor necrosis factor-related apoptosis inducing ligand (sTRAIL) and its soluble death receptor (sDR4, sDR5) in essential hypertension (EH) patients with left ventricular hypertrophy (LVH). Methods: Enzyme linked immunosorbent assay (ELISA) was used to measure plasma levels of sTRAIL, sDR4 and sDR5 in 50 EH + LVH patients (EH + LVH group), 50 EH patients without LVH (EH group) and 50 healthy subjects (healthy control group), and the results were compared and analyzed among three groups. Results: ① Compared with healthy control group and EH group, there were significant increase in plasma levels of sTRAIL [(0.95±0.11) ng/ml vs. (1.12±0.86) ng/ml vs. (1.74±1.19) ng/ml], sDR4[(2.38±0.32) pg/ml vs. (5.63±1.05) pg/ml vs. (8.72±1.14) pg/ml] and sDR5[(0.05); ② Pearson correlation analysis indicated that there were significant positive correlation among levels of sTRAIL, sDR4 and sDR5 in EH + LVH patients (r=0.325~0.410, P<0.05 or <0.01). Conclusion: Plasma levels of sTRAIL, sDR4 and sDR5 may be valuable indexes for prediction of left ventricular hypertrophy in patients with hypertension.
