|---|
Background: Heart failure has a poor prognosis, yet drugs known to improve outcomes are either not prescribed, or prescribed at sub-therapeutic doses. The National Service Framework (NSF) for coronary heart disease recommended specialist heart failure clinics to address this problem but their efficacy has not been evaluated.
Objectives: To determine the effectiveness of a protocol-driven heart failure clinic staffed by nurse and pharmacist specialists for improving symptoms and optimising treatment with key therapeutic agents, without adversely affecting renal function.
Results: Of the 234 patients with at least one follow-up visit, 127 (57%) were receiving none or only one key therapeutic agent when first seen, this was reduced to 25 patients (11%) at most recent follow-up. The improvement in prescription rates was accompanied by significant up-titration of dose, the proportion of patients on "medium" or "high" doses rising from 43 (18%) to 134 (57%) for beta-blockers, and from 129 (55%) to 201 (86%) for ACE-inhibitors/angiotensin receptor blockers. Clinical improvement was reflected in reductions in patients with NYHA functional classes III and IV (93 (40%) to 53 (23%)), and in patients with moderate or severe symptoms. Significant reductions in alcohol consumption and cigarette smoking were recorded. Up-titration of treatment was associated with reductions in heart rate and systolic blood pressure; increases in serum potassium and creatinine concentrations were small.
Conclusion: In a heart failure clinic staffed by nurse and pharmacist specialists, it is possible to achieve target doses of key therapeutic agents and improve symptoms without adversely affecting electrolytes or renal function.
