Abstract:
Objective:To investigate the serum levels of soluble growth stimulation expression gene 2 protein (sST2) and inflammatory factors in patients with acute left ventricular ejection fraction reduction heart failure (HFrEF) treated with sacubitril/valsartan.Methods:Ninety six patients with acute HFrEF admitted in The Affiliated Hospital of Qingdao University from March 2020 to March 2021 were enrolled. The patients were treated with sacubitril/valsartan,the dose was gradually increased from 50 mg b.i.d to the target dose of 200 mg b.i.d according to hemodynamics. After 12 weeks, the target dose was achieved in 72 cases (compliance group), and did not achieved in 24 cases (non-compliance group). The serum levels of sST2, IL-1β, IL-6, TNF-αand IL-10 were measured and compared between the two groups. The changes in left atrial anteroposterial diameter (LA), left ventricular end-diastolic diameter (LVDd) and left ventricular ejection fraction (LVEF) values were assessed with echocardiography. The adverse reactions, readmission rate and all-cause death within 3 months after discharge were compared between the two groups.Results:A total of 96 patients with acute HFrEF completed the follow-up, including 72 patients (75.0%) in the compliance group and 24 (25.0%) in the non-compliance group; aged 50-75 (66.1±6.7) years old, and 68 (70.8%) males. After treatment, the serum levels of sST2, IL-1β, IL-6 and TNF-α were decreased, and the IL-10 level was increased in both groups ( P<0.05); while the improvement of serum indicators in the compliance group was more marked ( P<0.05). Echocardiography showed that the LA, LVDd, and LVEF were significantly increased after treatment ( P<0.05) in compliance group, while there was no significant changes before and after treatment in the non-compliance group. SST2, inflammatory factors and echocardiographic measurements of patients in the standard group had statistical significance before and after treatment ( P<0.05), and the difference showed a downward trend. No deterioration of renal function and angioedema were observed in both groups, and there was no significant difference in hyperkalemia (two in compliance group and one in non-compliance group), symptom hypotension (each in two groups) between the two groups (χ 2=0.12, 0.68; P>0.05). In the non-compliance group, 10 patients (41.7%) were readmitted due to heart failure, and 6 patients (25.0%) died; while there were no readmitted cases or fatal cases in compliance group (χ 2=33.49, 19.20; P<0.05). Conclusion:Early application of sacubitril and valsartan sodium in patients with acute HFrEF after hemodynamic stabilization can significantly improve left ventricular remodeling, for those with earlier escalation to the target dose, it is more beneficial. The changes of serum sST2 and inflammatory factor level after treatment may predict the efficacy of sacubitril/valsartan therapy.
