Abstract

OBJECTIVE:

The objective was to study the association between B-type natriuretic peptide (BNP) and tumour markers and heart failure (HF) to evaluate the value of BNP and carbohydrate antigen 125 (CA125) in HF patients.

DESIGN AND SETTING:

A university hospital-based cross-over study of 285 subjects (157 men and 128 women) in HF, chronic obstructive pulmonary disease (COPD), mild-mid pulmonary hypertension patients and control subjects.

RESULTS:

CA125 and BNP were significantly higher in the HF group than in the non-HF group and in severe HF than in mild HF (P < 0.01). No changes were observed in other tumour markers. CA125 and BNP decreased obviously after clinical improvement by aggressive treatment (P < 0.01). Left ventricular ejection fraction correlated positively with CA125 (r = 0.789, P < 0.01) and BNP (r = 0.730, P < 0.01) in left heart failure patients, but not in other patients. BNP and CA125 had better accuracy and positive predictive value in diagnosing HF from the characteristic receiver-operator curve.

CONCLUSIONS:

CA125 and BNP are markedly elevated in heart failure and closely reflect heart function. They are better markers in evaluating the efficiency of short-term therapy. Detecting BNP combined with CA125 may be more valuable than only detecting BNP or CA125 for diagnosing HF and evaluating the efficiency of treatment.
