Abstract:
Objective:To investigate the relationship between peripheral blood sST2 level and prognosis in patients with heart failure (HFpEF) complicated with hypertension with ejection fraction preservation.Methods:A total of 122 patients with HFpEF hospitalized in Teda International Cardiovascular Hospital and Baoding First Central Hospital from May 5, 2021 to March 9, 2023 were selected. According to whether they were combined with hypertension, they were divided into HFpEF combined with hypertension group (73 cases, 32 males, (67.56±12.06) years old). There were 41 females (70.61±9.95 years old) and 49 males (67.00±11.64 years old) in the HFpEF group alone. There were 24 female patients (70.12±7.49 years old). sST2 levels in peripheral blood were compared between the two groups.HFpEF patients with hypertension were grouped by hypertension grade and prognosis, and the difference of sST2 in different groups was compared. Logistic regression was used for multivariate analysis. ROC curve to evaluate the diagnostic value of sST2 in the poor prognosis of HFpEF patients with hypertension. Patients were followed up regularly and major adverse cardiac events were recorded within 6 months after discharge, including cardiogenic death and heart failure re-hospitalization. The critical value of poor prognosis diagnosed by sST2 was divided into two groups, survival analysis was performed by Kaplan-Meier,and the Log Rank test was performed. Cox regression analysis was performed to determine whether high levels of sST2 were a risk factor for poor prognosis after 6 months of follow-up.Results:There was no significant difference in sST2 in HFpEF combined with hypertension and HFpEF alone ( P>0.05). sST2 was higher in grade 2 and 3 than in grade 1 hypertension (23.83 ng/ml vs. 12.68 ng/ml, Z=-2.778, P=0.005; 22.54 ng/ml vs. 12.68 ng/ml, Z=-2.865, P=0.004); BNP was higher in grade 3 hypertension than in grade 1 hypertension (582.95 pg/ml vs. 154.50 pg/ml, Z=-2.101, P<0.05). sST2 and BNP were higher in the poor prognosis group than in the good prognosis group (30.10 ng/ml vs. 18.95 ng/ml, Z=-2.803; 685.00 pg/ml vs. 347.50 pg/ml, Z=-2.385), all P<0.05. Logistic regression analysis showed that sST2 was a risk factor for poor prognosis ( OR=1.045, P=0.013). The auxiliary diagnostic value of sST2 level in HFpEF patients with hypertension was analyzed by ROC curve (AUC was 0.721, P<0.05). The incidence of cardiac adverse events in sST2>29.12 group was higher than that in sST2≤29.12 group (44.00% vs. 14.58%), and the difference was statistically significant (χ 2=7.657, P=0.006). Kaplan-Meier survival analysis showed that the percentage of patients with no endpoint event in the sST2≤29.12 group was higher than that in the sST2>29.12 group ( P=0.003).Cox regression analysis showed that the risk of endpoint event in sST2>29.12 group was 3.879 times that in sST2≤29.12 group ( OR=3.879, P=0.011). Conclusions:sST2 level can be used as an indicator of poor prognosis in HFpEF patients with hypertension, and can be used to stratify the risk of HFpEF patients. High levels of sST2 are associated with major adverse cardiac events.
