Nurse Specialising Consultation in Heart Failure: Impact on Drug Titration and Cardiovascular Events in Patients with Heart Failure and Reduced Ejection Fraction.

Introduction: The increasingly active role of nurses in the management of heart failure (HF) has become important in HF units (HCUs). This study aims to determine the effect of opening a specialised HF nursing (NSHF) consultation in a tertiary hospital on drug titration, and its subsequent impact on cardiac remodelling and prognosis. Methods: A retrospective cohort study was conducted on patients with HF with reduced ejection fraction (HFrEF) who were treated between 2017 and 2020. Patients who were followed by the NSHF were compared with those who underwent conventional clinical follow-up (non-NSHF), focusing on drug optimisation, echocardiographic parameters, biomarkers, and clinical outcomes in terms of mortality and hospital readmissions for HF. Results: A total of 411 patients were analysed, 85 of whom (20.7%) were treated with NSHF. There were hardly any differences in baseline characteristics. At the end of follow-up, the NSHF group had a higher prescription rate of angiotensin receptor-neprilysin inhibitor (+31.7% vs. +23.3%; p < 0.001), beta-blockers (+2.4% vs. -5.8%; p < 0.001), and sodium glucose co-transporter type 2 inhibitors (+24.7% vs. +17.8%; p < 0.001). There was also a higher rate of loop diuretic withdrawal (-16.7% vs. -6.7%; p < 0.001). However, no improvement in reverse remodelling or neurohormonal response was observed. Patients treated with NSHF had a lower probability of dying from HF (88.6% vs. 63.3%; p = 0.006), but this did not reduce hospital admissions for HF. Conclusions: Patients with HFrEF who are cared for through NSHF are more likely to be prescribed drugs that modify the prognosis of the disease. This has an impact on their mortality.
