Abstract:
Objective:To explore the judging value of brain natriuretic peptide (BNP) on patient's condition of male patients with senile degenerated heart valvular disease (SDHVD) complicated heart failure (HF) .Methods :A total of 67 SDHVD + HF male patients were regarded as SHDVD group ,another 43 male HF patients ,who accepted treatment during the same period with corresponding age and without valvular heart disease ,were enrolled as pure HF group .Cardiac function indexes and plasma BNP level were measured and compared between two groups ,the correlation between BNP and left ventricular end -diastolic dimension (LVEDd) was analyzed ,and the cutoff point of BNP level for judging severity of SDHVD + HF was also calculated .Results:Compared with pure HF group , there were significant rise in LVEDd [ (49.79 ± 4.31) mm vs .(53.04 ± 7.10) mm] and plasma BNP level [ (214.43 ± 237.71) pg/ml vs . (682.06 ± 981.15 ) pg/ml ] , and significant reduction in left ventricular ejection fraction [LVEF ,(64.84 ± 5.83)% vs .(58.24 ± 7.99)% ] , P<0.05 or <0.01;percentage of moderate -severe heart dys‐function (NYHA class Ⅲ + Ⅳ) in SDHVD group was significantly higher than that of pure HF group (56.72% vs . 37.21% ) ,χ2 =3.988 , P=0.046. Spearman correlation analysis indicated that BNP level was positively correlated with LVEDd (r=0.588 ,P= 0.001) .The area under ROC (AUC) of BNP was 0.975 ,and the critical point of BNP level judging severity of male SDHVD complicated HF was 312 pg/ml ,and its sensitivity and specificity was 86.8% and 96.6% respectively .Conclusion:The SDHVD patient's condition is more severe compared with patients without valvular heart disease ,and BNP level is help to judging patient's condition .
