Purpose:The objective of this study was to explore the relationship among serum levels
of the growth-stimulating expressed gene 2 protein (ST2), Galectin-3(GAL-3), N-terminal pro-B-type
natriuretic peptide (NT-proBNP) in elderly hypertensive patients and heart failure with preserved
ejection fraction (HFpEF).Materials and Methods:Eighty-five elderly hypertensive patients with HFpEF were registered as the
HFpEF group, and 46 hypertensive patients without HF were registered as the Non-HF group. The
levels of serum sST2 (soluble ST2), Galectin-3, and NT-proBNP were measured, and related indexes
of heart function were performed with echocardiography in two groups, respectively.The obtained
variables were applied to statistical software for analysis.Results:Age, BMI, SBP, DBP, TC, LDL-C, HCY, sST2, Galectin-3, NT- proBNP, LVEDD, IVSD,
LVEF, and E/A were obviously different between the two groups (p < 0.05). The levels of sST2, Galectin-
3 and NT- proBNP in the HFpEF group were higher than in the Non-HF group (P < 0.05).
ANOVA results indicated that sST2, Galectin-3, and NT- proBNP levels increased gradually with the
increasing NYHA grades (P<0.05). BMI, SBP, DBP, TC, LDL-C, FBG,UA, HCY, LVEDD, IVSD,
LVEF, and E/A were significant differences in patients with different NYHA classes (P < 0.05).
Spearman indicated that sST2, Galectin-3, and NT-proBNP were positively correlated with BMI,
SDP, DBP, LDL-C, FBG, and HCY (P < 0.05). Logistic analysis indicated that BMI, SBP, DBP,
FBG, HCY,sST2, Galectin-3, NT-proBNP, LVEDD, LVEF, and E/A were risk factors for hypertension
with HFpEF. (P < 0.05). ROC indicated that the AUC of the diagnostic performance of sST2,
Galectin-3, and NT-proBNP were all above 0.7, which may have some forecasting value for elderly
hypertensive patients with HFpEF.Conclusion:The levels of sST2, Galectin-3, and NT-proBNP were closely related to cardiac function
grades. sST2, Galectin-3, and NT-proBNP have similar diagnostic performance and predictive value
for elderly hypertensive patients with HFpEF. sST2 was more sensitive than NT-proBNP. It is recommended
that measurements of sST2, Galectin-3 and NT-proBNP levels in elderly hypertensive
patients may be useful in classifying early HFpEF.
