Background: Type 2 sodium-glucose cotransporter inhibitors (SGLT2i) are among the main therapeutic options for patients with chronic heart failure with reduced ejection fraction (HFrEF). The aim of this study was to evaluate the effects of SGLT2i on the echocardiographic parameters of left (LV) and right (RV) ventricular function among outpatients with a long history of HFrEF, in optimized therapy. Methods: We evaluated consecutive patients affected by HFrEF in whom the SGLT2i therapy was prescribed. Following a baseline evaluation (T0), in which SGLT2i was prescribed, patients were re-evaluated at 3 (T3), 6 (T6), and 12 (T12) months. Results: We considered 60 patients for the analysis with a median history of HFrEF of more than seven years in optimal medical and electrical therapy. After SGLT2i therapy, LV ejection fraction and LV global longitudinal strain improved from baseline at T3, T6, and T12. Analogously, RV global and free wall longitudinal strain improved at T3 and T6. Conclusions: Our study shows that the addition of SGLT2i to the optimized therapy for HFrEF was associated with a significant improvement in both LV and RV function, thus highlighting a possible mechanism responsible for the benefit obtained with this class of drugs.

Background: Spontaneous coronary artery dissection (SCAD) is a relatively rare condition affecting predominantly young adults, with a prevalence of female sex. The best management of SCAD is still unclear and not adequately evidence-based both in the acute phase but especially over the long-term. We therefore aimed to evaluate the impact of medical therapy usually adopted for coronary artery disease on long-term outcome in SCAD patients. Methods: We performed a meta-regression analysis including all the studies evaluating the long-term outcome of patients affected by SCAD. We used long-term mortality, recurrent SCAD, admission for angina and major adverse cardio-vascular events (MACE) as dependent variables and the rates of discharge drug rates (beta-blockers, statins, renin-angiotensin-aldosterone system inhibitors, aspirin, dual antiplatelet therapy (DAPT)) as independent variables. Results: Fourteen observational studies were included with a long-term follow-up of 3.5 ± 1.7 years. No statistically significant correlations between drug therapy (beta-blockers, statins, calcium channel blockers, nitrates, renin-angiotensin-aldosterone inhibitors) and mortality, MACE, admission for angina, and SCAD recurrence were found. Higher aspirin use rates were significantly correlated with lower admission rates for angina (p < 0.05); DAPT, however, showed a borderline correlation with higher rates of SCAD recurrence (p = 0.068). Conclusions: In a meta-regression analysis including observational studies aspirin use rates correlated with lower long-term rates of admission for angina, while a borderline correlation between DAPT and rates of SCAD recurrence was found. Other drugs usually used for the treatment of coronary artery disease do not seem to impact long-term outcome of SCAD patients.

Background: The sodium–glucose cotransporter-2 inhibitors (SGLT2i) have emerged as a crucial therapeutic option for patients with chronic heart failure with reduced ejection fraction (HFrEF). The aim of this study was to evaluate, in a real-world population from a single centre, the feasibility of introducing SGLT2i and their interaction with other recommended drug classes. Methods: Consecutive patients affected by chronic heart failure (CHF) were evaluated beginning in January 2022. At the baseline clinical visit, both the patient’s current medication and the prescribed treatments were recorded. Over a 6- to 12-month follow-up, changes in concomitant therapy were analysed. Results: At baseline, among 350 patients evaluated, only 17 (5%) were already taking SGLT2i: 13 with HFrEF, five with mildly reduced (HFmrEF), preserved (HFpEF) or improved (HFimpEF) ejection fraction. After the baseline assessment, SGLT2i were prescribed to 224 (64%) of the patients, including 179 (84%) with HFrEF, 27 (42%) with HFmrEF/HFimpEF, and 18 (22%) with HFpEF/HFimpEF. After follow-up, SGLT2i therapy was well tolerated and was associated with a significant increase in sacubitril/valsartan prescriptions and a decrease in diuretic use. Finally, a significant improvement in functional status and left ventricular systolic function after SGLT2i therapy was observed. Conclusions: In this single-centre, real-world study, SGLT2i were primarily prescribed to HFrEF patients who were already on other recommended drug classes for their treatment. Additionally, there was a noticeable enhancement in the prescribed therapy during a short-term follow-up. These findings further bolster the inclusion of this therapeutic approach in regular clinical practice.

Background. The type-2 sodium-glucose cotransporters inhibitors (SGLT2i) are a new relevant therapeutic option for patients affected by chronic heart failure with reduced ejection fraction (HFrEF). The aim of this study was to evaluate, in a real-world population from a single center, the feasibility of introducing SGLT2i and their interaction with other recommended drug classes. Methods. We evaluated the consecutive patients affected by chronic heart failure (CHF) since January 2022. At baseline clinical visit the therapy taken by the patients as well as that prescribed were accurately collected. During a 6-12 month follow-up the the changes in concomitant therapy were analyzed. Results. At baseline, among 350 patients evaluated, only 17 (5%) were already taking SGLT2i, 13 with HFrEF, 2 with CHF with mild reduced (HFmrEF) and 2 with preserved ejection fraction (HFpEF). After baseline evaluation, SGLT2i were prescribed to 220 (63%) of all the patients enrolled, among whom 178 (84%) of HFrEF patients, 25 (42%) of HFmrEF and 17 (22%) of HFpEF. After follow-up, SGLT2i therapy was highly tolerated and it was associated with a significant increased prescription of sacubitril/valsartan and a reduced use of diuretics. Finally, a significant improvement in functional status and left ventricular systolic function after SGLT2i therapy was observed. Conclusions. In this single center “real world” study, SGLT2i were prescribed in HFrEF patients most of all already in therapy with the other classes of drugs currently recommended for their treatment. Moreover, a further optimization in prescribed ther-apy was observed during a short term follow-up. These data further support the use of this thera-peutic approach in routine clinical practice.
