Correlation between N-terminal pro B type natriuretic peptide and cystatin C content in Kazak patients with hypertensive heart disease / 心血管康复医学杂志

ABSTRACT

Objective:To deteat N‐terminal pro B type natriuretic peptide (NT‐pro BNP) and cystatin C (Cys C) con‐tent in Kazak patients with hypertensive heart disease (HHD) complicated heart failure (HF) and analyze the corre‐lation between them .Methods:A total of 100 Kazak HHD patients were divided into hypertension complicated HF group (Complicated HF group , n=50) and pure HHD group (n=50) .Venous blood sample was taken within 24h after hospitalization for measuring serum levels of NT‐proBNP and Cys C ,then they were compared and analyzed between two groups .Results:Compared with pure HHD group ,there were significant rise in serum levels of NT‐proBNP [ (246.53 ± 165.65) ng/L vs .(4568.32 ± 2722.36) ng/L] and Cys C [ (0.82 ± 0.31) mg/L vs .(1.93 ± 2.46) mg/L] in complicated HF group , P< 0.01 both .Spearman correlation analysis indicated that serum NT‐proBNP level was positively correlated with Cys C level in complicated HF group , r=0.961 , P<0.01. Conclusion:In Kazak patients with hypertensive heart disease complicated HF ,serum NT‐proBNP and Cys C levels significantly rise and they significantly positively correlate ,so it suggest there may be slight damaged renal function also .
