Natriuretic Peptide Testing in Primary Care: The Evidence is Settled, Implementation is Not

Key Points

• The aim is to assess the role of natriuretic peptide testing in diagnosing heart failure within primary care settings.
• Randomized trial with primary care practitioners
• Evaluation of natriuretic peptide levels in patients with heart failure symptoms
• Assessment of diagnostic accuracy and implementation strategies
• Natriuretic peptide testing improved the diagnostic accuracy of heart failure in primary care (p<0.01).
• Increased identification of heart failure cases when natriuretic peptides were utilized (30% detection rate).
• Implementation challenges noted despite evidence of effectiveness.
