Background: Worsening heart failure (WFH) includes heart failure (HF) hospitalisation, representing a strong predictor of mortality in patients with heart failure with reduced ejection fraction (HFrEF). However, there is little evidence analysing the impact of the number of previous HF admissions. Our main objective was to analyse the clinical profile according to the number of previous admissions for HF and its prognostic impact in the medium and long term. Methods: A retrospective study of a cohort of patients with HFrEF, classified according to previous admissions: cohort-1 (0–1 previous admission) and cohort-2 (≥2 previous admissions). Clinical, echocardiographic and therapeutic variables were analysed, and the medium- and long-term impacts in terms of hospital readmissions and cardiovascular mortality were assessed. A total of 406 patients were analysed. Results: The mean age was 67.3 ± 12.6 years, with male predominance (73.9%). Some 88.9% (361 patients) were included in cohort-1, and 45 patients (11.1%) were included in cohort-2. Cohort-2 had a higher proportion of atrial fibrillation (49.9% vs. 73.3%; p = 0.003), chronic kidney disease (36.3% vs. 82.2%; p < 0.001), and anaemia (28.8% vs. 53.3%; p = 0.001). Despite having similar baseline ventricular structural parameters, cohort-1 showed better reverse remodelling. With a median follow-up of 60 months, cohort-1 had longer survival free of hospital readmissions for HF (37.5% vs. 92%; p < 0.001) and cardiovascular mortality (26.2% vs. 71.9%; p < 0.001), with differences from the first month. Conclusions: Patients with HFrEF and ≥2 previous admissions for HF have a higher proportion of comorbidities. These patients are associated with worse reverse remodelling and worse medium- and long-term prognoses from the early stages, wherein early identification is essential for close follow-up and optimal intensive treatment.

Background: Heart failure (HF) is one of the mayor contributors to cardiovascular morbidity and mortality in patients with diabetes. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have demonstrated to reduce the risk of hospitalization for HF in patients with type 2 diabetes mellitus (T2D). We aimed to assess the risk for re-hospitalization in a cohort of patients hospitalized for HF according to whether or not they received canagliflozin at discharge, as well as changes in N-terminal pro–B-type natriuretic peptide (NT-ProBNP) concentration during follow-up. Methods: We conducted a retrospective longitudinal study at a tertiary centre including 102 consecutive T2D patients discharged for acute HF without contraindication for SGLT2 inhibitors. We compared adverse clinical events (HF rehospitalization and cardiovascular death) and NT-ProBNP changes according to canagliflozin prescription at discharge. Results: Among the 102 patients included, 45 patients (44.1%) were prescribed canagliflozin and the remaining 57 (55.9%) were not prescribed any SGLT2 inhibitors (control group). After a median follow-up of 22 months, 45 patients (44.1%) were hospitalized for HF. Most of the rehospitalizations occurred during the first year (37.3%). HF readmission at first year occurred in 10 patients (22.2%) in the canagliflozin group and 29 patients (49.1%) in the control group (hazard ratio (HR): 0.45; 95% confidence interval (CI): 0.21–0.96; p < 0.039). A composite outcome of hospitalization for HF or death from cardiovascular causes was lower in the canagliflozin group (37.8%) than in the control group (70.2%) (HR: 0.51; 95% CI: 0.27–0.95; p < 0.035). Analysis of NT-ProBNP concentration showed an interaction between canagliflozin therapy and follow-up time (p = 0.002). Conclusions: Canagliflozin therapy at discharge was associated with a lower risk of readmission for HF and a reduction in NT-ProBNP concentration in patients with diabetes after hospitalization for HF.

Background: The therapeutic management of patients with multivessel disease and severe left ventricular dysfunction is complex and controversial.Aims: The aim of this study was to analyze the clinical outcomes and the changes in left ventricular ejection fraction (LVEF) in patients with severe left ventricular dysfunction and at least one chronic total occlusion (CTO) undergoing percutaneous coronary intervention (PCI) with hemodynamic support provided by Impella.Methods: Retrospective, multicenter study enrolling patients with severe left ventricular dysfunction and severe coronary artery disease with at least one CTO who required percutaneous mechanical circulatory support with Impella, from January 2019 to December 2023. The primary endpoints were the incidence of MACE (composite of cardiovascular death, acute myocardial infarct, and target lesion revascularization) at 90 days. The secondary endpoint was changes in LVEF and functional class during the same period.Results: A total of 27 patients (34 CTOs) were included in the study. The mean SYNTAX score was 35 ± 11. The median J‐CTO score of 2 (1–3). At 90 day of follow‐up, there were three MACE (11%), two cardiovascular deaths and one TLR; three vascular complications were related to access for the Impella device (only one required invasive treatment); and LVEF improved significantly after revascularization (delta LVEF: 10% [CI 95% 6, 15]). A total of 81% of patients improved their angina or dyspnea status at 90 days.Conclusions: In high‐risk patients with severe left ventricular dysfunction with complex coronary disease including CTO, PCI with mechanical circulatory support using the Impella device is associated with favorable safety and efficacy outcomes at short‐term follow‐up.

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.
