Chinese Journal of Postgraduates of Medicine 2021;44(4):342-347
Objective:To investigate the expression of serum galectin-3 (Gal-3), cystatin-C (Cys-C) and endothelin-1 (ET-1) in elderly patients with hypertension and analyze their correlation with left ventricular hypertrophy(LVH).Methods:A total of over 65 years old 110 patients with essential hypertension in Tieling Central Hospital from July 2018 to May 2019 were selected as hypertension group, according to the LVH, patients with essential hypertension were divided into (non LVH group, 66 patients) and LVH group (44 patients). At the same time, a total of 110 healthy people in the same period were selected as control group. The expressions of serum Gal-3, Cys-C and ET-1 in each group were compared, and the correlation between left ventricular mass index (LVMI) and Gal-3, Cys-C in patients with essential hypertension were analyzed.Results:The levels of Gal-3, Cys-C and ET-3 in the hypertension group were higher than those in the control group: (132.28 ± 38.18) μg/L vs. (110.60 ± 17.51) μg/L, (1.19 ± 0.12) mg/L vs. (0.81 ± 0.06) mg/L, (21.28 ± 0.72) ng/L vs. (16.50 ± 0.68) ng/L, and the differences were statistically significant ( P<0.05). The levels of Gal-3, Cys-C and ET-1 in the LVH group were significantly higher than those in the non LVH group: (159.75 ± 36.37) μg/L vs. (113.96 ± 26.79) μg/L, (1.24 ±) mg/L vs.(1.16 ± 0.08) mg/L, (21.84 ± 0.71) ng/L vs.(20.90 ± 0.41) ng/L, and the differences were statistically significant ( P<0.05). Pearson correlation analysis showed that LVMI was positively correlated with Gal-3( r=0.650, P<0.01), Cys-C( r=0.659, P<0.01) and ET-1( r=0.858, P<0.01). The receiver operating characteristic(ROC) curve showed that the area under the curve (AUC) of Gal-3 in diagnosing hypertensive LVH was 0.821, 95% CI 0.743-0.899, the cutoff value was 148.55 μg/L, and the sensitivity and specificity were 59.10% and 89.40%. The AUC of Cys-C in diagnosing hypertensive LVH was 0.672, 95% CI 0.558-0.786, the cutoff value was 1.320 mg/L, and the sensitivity and specificity were 43.20% and 98.50%. The AUC of ET-1 in diagnosing hypertensive LVH was 0.876, 95% CI 0.811-0.941, the cutoff value was 22.275 ng/L, and the sensitivity and specificity were 65.90% and 95.50%. The AUC of combined detection was 0.948, 95% CI 0.855-0.976, and the sensitivity and specificity were 84.10%, 98.50%. Conclusions:The serum levels of Gal-3, Cys-C and ET-1 in elderly patients with hypertension are significantly increased, and there are a good correlation between them and LVH, and combined detection can be used as a sensitive index for the diagnosis of hypertensive LVH.
