Background Cardiac remodelling is an adverse phenomenon linked to heart failure progression. Cardiac remodelling could represent the real therapeutic goal in the treatment of patients with heart failure with reduced ejection fraction (HFrEF), being potentially reversed through different pharmacotherapies. Currently, there are well-established drugs such as angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers and β-blockers with anti-remodelling effects; recently, angiotensin receptor neprilysin inhibitor effects on inhibiting cardiac remodelling were demonstrated. Benefits of gliflozins on left ventricular hypertrophy, dilation, and systolic and diastolic function were also described. Aim of study to evaluate possible echocardiographic differences between patients with HFrEF in treatment with ARNI or SGLT2I and patients with HFrEF in therapy with ARNI plus SGLT2i. Materials Between June 2021 and April 2022, consecutive patients with HFrEF underwent to conventional and advanced echocardography (TDI, 2DSTE). After 3 month, these patients underwent to echocardiographic follow-up. Results 76 patients (68 male, 66,51±9,68 years old) with HFrEF were enrolled in the study. After 3 month of therapy, there was an inverse relation between number of HFrEF drugs (0, 1 or 2) and echocardiographic parameters [E/E’ (r: -0,28; p: 0,036) and E/A (r: -0,37; p: 0,012)]. Conclusions About cardiac remodelling, there are not significant echocardiographic differeces but a better trend for the diastolic dysfunction in patients with HFrEF in treatment with ARNI plus SGLT2i vs HFrEF patients in therapy with ARNI or SGLT2i was showed.

Aims Observational studies have demonstrated that treatment with sacubitril/valsartan may improve left ventricular (LV) systolic and diastolic function in subjects with reduced LV ejection fraction (LVEF) in real-world studies. Subjects with heart failure and reduced EF (HFrEF), however, are also characterized by an impaired right ventricular (RV) function. We therefore aimed to evaluate whether also RV function may improve after S/V therapy and possible predictors of RV improvement could be identified at echocardiography and tissue Doppler imaging. Methods Fifty consecutive patients (67 ± 8 years, LVEF 28 ± 6%, male 86%) with chronic HFrEF and NYHA Classes II–III were followed up for 6 months after therapy with S/V. LV&RV function was assessed at baseline and after 6 months of therapy. Results After 6-month therapy with S/V a significant improvement was shown in the following echocardiography parameters assessing RV function: PAsP (31 ± 11 vs. 35 ± 10 mmHg, P Conclusions In a real-world scenario, 6-month therapy with S/V was associated with an improved RV function in HFrEF. RV function improvement may be predicted by assessing baseline RV S’ and right atrial volume values.
