Abstract:
Objective: To explore the relationships between blood levels of osteopontin (OPN), brain natriuretic peptide (BNP) and cardiac function in patient with degenerative heart valve disease (DHVD). Methods: Our research included in 2 groups: DHVD group,n=120 relevant patients treated in our hospital from 2013-12 to 2015-02 and Control group,n=30 healthy subjects from physical examination in the same period of time. Based on blood levels of OPN, DHVD patients were further divided into 2 sub-groups as Normal OPN sub-group, the patients with 18.8 ng/ml ≤OPN≤ 30.0 ng/ml,n=35 and High OPN sub-group, the patients with OPN>30.0 ng/ml,n=85. OPN levels at prior treatment (T0) and 3 days (T1), 1 week (T2), 2 weeks (T3) after treatment were compared between DHVD group and Control group; BNP levels, cardiac outcome (CO), cardiac index (CI) and left ventricular ejection fraction (LVEF) were also compared. The relationships between blood levels of OPN, BNP and cardiac function in DHVD patients were studied by Pearson correlation analysis. Results: Compared with Control group at T0 time point, High OPN sub-group showed increased blood levels of OPN and BNP, while decreased CO, CI and LVEF. Compared with Normal OPN sub-group, High OPN sub-group had the higher levels of OPN and BNP at all 4 time points, while lower levels of CO, CI and LVEF. In DHVD group, compared with T0 time point, OPN and BNP levels were decreased at T2 and T3 time points, while CO, CI and LVEF were increased, allP<0.05. Pearson correlation analysis presented that in DHVD patients, blood levels of OPN were positively related to BNP (r=0.936,P=0.00) and negatively related to CO, CI and LVEF (r=-0.869,r=-0.884 andr=-0.858 respectively, allP=0.00). Conclusion: DHVD patients had increased blood level of OPN which is related to BNP level and cardiac function; this might be because of OPN promoting heart valve calciifcation, inlfammatory reaction and myocardial injury. OPN could be used as a reference index for evaluating the cardiac function in DHVD patients.
