Diagnostic value of brain natriuretic peptide and β-endorphin plasma concentration changes in patients with acute left heart failure and atrial fibrillation.

Abstract：

RATIONALE:This study aims to evaluate the diagnostic value of beta-endorphin (β-EP) and brain natriuretic peptid (BNP) plasma concentrations for the early diagnosis of acute left heart failure and atrial fibrillation. PATIENT CONCERNS:A total of 45 patients were included. These patients comprised 23 male and 22 female patients,and 20 healthy subjects who underwent physical examinations in the Outpatient Department during the same periodwere included and assigned to the control group. DIAGNOSES:The diagnos stand was that of the Chinese guidelines for the diagnosis and treatment of heart failure. INTERVENTIONS:Enzyme-linked immunosorbent assay was performed to detect the plasma concentration of β-EP and BNP in the treatment and control groups, and electrocardiogram targeting was performed to determine the left ventricular ejection fraction (LVEF). OUTCOMES:BNP, β-EP, and LVEF levels were higher in the treatment group (688.01 ± 305.78 ng/L, 394.06 ± 180.97 ng/L, and 70.48 ± 16.62%) compared with the control group (33.90 ± 8.50 ng/L, 76.87 ± 57.21 ng/L, and 32.11 ± 5.25%). The P-values were .015, .019, and .026, respectively, which were <.05. The difference was statistically significant. The BNP and β-EP's 4 correlations (r = 0.895, P <.001), BNP, β-EP, and the combination of BNP and β-EP for acute left heart failure diagnosis in maximizing Youden index sensitivity, specific degree, area under the ROC curve (AUC), and 95% confidence interval (CI) were respectively 93.5%, 81.3%, 0.921, 0.841, 0.921; 80.5%, 78.6%, 0.697, 0.505, 0.697; 94.1%, 83.5%, 0.604 to 0.979, and 0.604. Acute left heart failure in patients with LVEF acuity plasma BNP and β-EP 50% group was obviously lower than that in the LVEF <50% group (P <.01). BNP, β-EP, and LVEF were negatively correlated (r = -0.741, -0.635, P = .013, .018). LESSONS:β-EP and BNP have high specificity and sensitivity for detecting early acute left heart failure and atrial fibrillation in patients, which is convenient, easy to perform, and suitable for clinical applications.
