摘要:
Objective: To explore assessment value of change of brain natriuretic peptide (BNP) level for cardiac function and prognosis judgment in patients with acute heart failure (AHF).Methods: After standard medicinal treatment, according to whether BNP level after treatment reduced <30% or rose compared with at hospitalization, a total of 91 AHF inpatients were divided into BNP reduction ≥30% group (n=67) and BNP reduction <30% or rise group (n=24).Left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDd) and 6min walking distance (6MWD) at discharge were compared between two groups.All patients were followed up for 12 months.Multi-factor Logistic regression analysis was used to analyze risk factors for cardiogenic death.and adverse cardiac events were recorded.Results: Compared with BNP reduction ≥30% group, there were significant reductions in LVEF [(46.00±5.46)% vs.(34.54±5.32)%] and 6MWD [(392.64±153.02)m vs.(136.75±56.25)m], and significant rise in LVEDd [(56.33±4.40)mm vs.(65.96±6.13)mm] in BNP reduction <30% group, P<0.01 all.Multi-factor Logistic regression analysis indicated BNP reduction <30% or rise was the only one independent risk factor for cardiogenic death (OR=2.714, P=0.039).Compared with BNP reduction ≥30% group, there was significant rise in incidence rate of adverse cardiac events (40.3% vs.62.5%) in BNP<30% group, and the Log-rank value was 30.264 (P=0.001).Conclusion: Change of plasma BNP level can be used as an important reference index for the evaluation of cardiac function and prognosis in patients with acute heart failure.
