Background: recent studies indicate that measurement of natriuretic peptides may be a valuable tool to improve the quality of the diagnosis of heart failure in general practice. Aim: the aim of the present study was to examine the relationship between the plasma level of the natriuretic peptide N‐terminal proANP and symptoms and signs of heart failure in patients from general practice in the Oslo area. Methods and Results: we undertook a survey of 499 patients consecutively enrolled from the practice of 27 practitioners. One hundred and twenty‐nine patients were classified as having possible or some degree of heart failure. The plasma concentration of N‐terminal proANP increased with severity of heart failure as judged from clinical examination. In multivariate analysis age, history of heart disease, plasma creatinine, use of beta‐blockers and digitalis, oedemas and atrial fibrillation were the main determinants of plasma N‐terminal proANP. Conclusion: while there was an overall increase in N‐terminal proANP values with increasing symptoms and degree of heart failure, no single finding was closely related to N‐terminal proANP. Treatment effects and diagnostic errors may both influence the relationship between N‐terminal proANP and clinical findings. The current study has demonstrated the feasibility of using N‐terminal proANP by general practitioners for the potentially improved diagnosis of heart failure. Further research is required to determine the precise role of this assay in clinical practice.
