Assessment of Clinical Values on N-terminal Pro-brain Natriuretic Peptide in Elder Patients With Heart Failure / 中国循环杂志

ABSTRACT

Objective: To assess the clinical value of serum N-terminal pro-brain natriuretic peptide (NT-ProBNP) values in elder patients with heart failure (HF). Methods: According to NYHA classiifcation, a total of 384 HF patients were divided into 4 groups as NYHA I group, n=35, NYHA II group, n=89, NYHA III group, n=163, NYHA IV group, n=97;and Control group, n=69 normal subjects. The NT-ProBNP and troponin (cTn1) levels were examined in systolic HF and diastolic HF patients, the relationship between NT-ProBNP and left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD) were studied. Results: For NT-ProBNP levels, Control group and NYHA I group were similar, P>0.05; while it was different among each HF groups, P0.05;while NYHA III group and NYHA IV group were different from other groups, P Conclusion: NT-ProBNP may better reflect the cardiac structural and functional changes in HF patients, it is important for HF early diagnosis and prognosis in clinical practice.
