A management programme for suspected heart failure in primary care in cooperation with specialists in cardiology

Background: The diagnosis of new onset congestive heart failure (CHF) is often difficult as symptoms and signs are non-specific. Proper diagnostic investigations and treatments are underused in primary care. Objective: To describe a management programme for patients with suspected CHF in primary care in cooperation with specialists in cardiology. Methods: Prospective study of 102 consecutive primary care patients with suspected new onset CHF referred to an easily accessible hospital-based cardiology outpatient clinic management programme. Following clinical examination, ECG, echocardiography, blood chemistry including NT-proBNP, and assessment of NYHA class and quality of life (EQ5D), patients with a confirmed diagnosis of CHF were prescribed medication with advice on titration and target doses. Trained CHF nurses gave Information on CHF and provided follow up. Results: Half (47%) of the referred patients had the diagnosis of CHF confirmed. Low NT-proBNP values (<300 ng/l) provided a negative predictive value of 73%. Respiratory tract diseases were common differential diagnoses. At one year of follow-up, medication in the CHF group was 86% ACE-inhibitors/angiotensin receptor blockers, 61% beta-blocking agents, and 81% diuretics (P < 0.001 for the increase in ACE-inhibitors/angiotensin receptor blockers from baseline). NYHA class improved from baseline (median 2, range: 1-3) to one year (P < 0.05), whereas NT-proBNP (1491-1261 ng/l), and quality of life (EQ5D; 67-67) were unchanged. Conclusion: A management programme to optimize quality of care for patients with suspected new onset CHF in primary care, with referral to a hospital-based specialist team, can be applied successfully.
