OBJECTIVE: Current guidelines recommend an implantable cardiac defibrillator (ICD) in patients with symptomatic heart failure and reduced ejection fraction (HFrEF; left ventricular ejection fraction [LVEF] ≤35%) despite ≥3 months of optimal medical therapy. Recent observations demonstrated that sacubitril/ valsartan induces beneficial reverse cardiac remodeling in eligible HFrEF patients. Given the pivotal role of LVEF in the selection of ICD candidates, we sought to assess the impact of sacubitril/ valsartan on ICD eligibility and its predictors in HFrEF patients. PATIENTS AND METHODS: We retrospectively evaluated 48 chronic HFrEF patients receiving sacubitril/valsartan and previously implanted with an ICD in primary prevention. We assumed that ICD was no longer necessary if LVEF improved >35% (or >30% if asymptomatics) at follow-up. RESULTS: Over a median follow-up of 11 months, sacubitril/valsartan induced a significant drop in LV end-systolic volume (-16.7 ml/ m2, p=0.023) and diameter (-6.8 mm, p=0.022), resulting in a significant increase in LVEF (+3.9%, p<0.001). As a consequence, 40% of previously implanted patients resulted no more eligible for ICD at follow-up. NYHA class improved in 50% of the population. A dose-dependent effect was noted, with higher doses associated to more reverse remodeling. Among patients deemed no more eligible for ICD, lower NYHA class (odds ratio (OR) 3.73 [95% CI 1.05; 13.24], p=0.041), better LVEF (OR 1.23 [95% CI 1.01; 1.48], p=0.032) and the treatment with the intermediate or high dose of sacubitril/valsartan (OR 5.60 [1.15; 27.1], p=0.032) were the most important predictors of status change. CONCLUSIONS: In symptomatic HFrEF patients, sacubitril/valsartan induced beneficial cardiac reverse remodeling and improved NYHA class. These effects resulted in a significant reduction of patients deemed eligible for ICD in primary prevention. [ABSTRACT FROM AUTHOR]

OBJECTIVE: The aim of the meta-analysis was to assess post-procedural outcome of the new generation of transcatheter aortic valve implantation (TAVI) devices, focusing on the transfemoral and balloon-expandable SAPIEN 3 (Edwards Lifesciences Inc., Irvine, CA, USA), the self-expanding CoreValveTM Evolut series R and PRO (R/PRO)TM (Medtronic Inc., Minneapolis, MN, USA) and ACURATE neo™ transcatheter aortic valve (Symetis SA, a Boston Scientific company, Ecublens, Switzerland). MATERIALS AND METHODS: All observational studies were retrieved through PubMed computerized database from January 2014 until June 30th, 2019. The risk difference (RD) with the 95% confidence interval (CI) was used to assess the effectiveness of the intervention under comparison. The primary end point was 30-day mortality. Safety end points included: (i) stroke, (ii) moderate/severe paravalvular leak, and (iii) the need for new permanent pacemaker implantation. RESULTS: Meta-analysis demonstrated no significant differences as regards to either 30-day mortality or stroke for all the groups of prostheses under comparison. ACURATE neo was associated with significantly less new permanent pacemaker implantation compared to SAPIEN 3 (RD: -0.06; 95% CI -0.08 to -0.03; p<0.0001; I2=0%) or to EVOLUT R/PRO (RD: -0.06; 95% CI -0.09 to -0.02; p=0.0009; I2=0%). A significant reduction of new permanent pacemaker need was observed in the group of patients implanted with SAPIEN 3 compared to EVOLUT R/PRO (RD: -0.07; 95% CI -0.09 to -0.04; p<0.00001; I2=7%). The occurrence of moderate/severe leak was significantly increased in the group of patients implanted with ACURATE neo vs. SAPIEN 3 (RD: 0.04; 95% CI 0.02 to 0.05; p<0.00001; I2=0%). No significant differences were found between ACURATE neo vs. EVOLUT R/PRO (RD: -0.01; 95% CI -0.04 to 0.02; p=0.69; I2=0%) and between SAPIEN 3 vs. EVOLUT R/PRO (RD: -0.01; 95% CI -0.04 to 0.01; p=0.28; I2=73%). CONCLUSIONS: The results of the meta-analysis show that: (1) ACURATE neo was associated with significantly less new permanent pacemaker implantation than SAPIEN 3 and EVOLUT R/PRO; (2) SAPIEN 3 had significantly lower occurrence of moderate/severe valvular leak than ACURATE neo.

Aims: Patients with heart failure (HF) display metabolic alterations, including heightened ketogenesis, resulting in increased beta-hydroxybutyrate (β-OHB) formation. We aimed to investigate the determinants and prognostic impact of circulating β-OHB levels in patients with advanced HF and reduced ejection fraction (HFrEF)., Methods and Results: A total of 867 patients with advanced HFrEF (age 57 ± 11 years, 83% male, 45% diabetic, 60% New York Heart Association class III), underwent clinical and echocardiographic examination, circulating metabolite assessment, and right heart catheterization (n = 383). The median β-OHB level was 64 (interquartile range [IQR] 33-161) μmol/L (normal 0-74 μmol/L). β-OHB levels correlated with increased markers of lipolysis (free fatty acids [FFA]), higher natriuretic peptides, worse pulmonary haemodynamics, and lower humoral regulators of ketogenesis (insulin/glucagon ratio). During a median follow-up of 1126 (IQR 410-1781) days, there were 512 composite events, including 324 deaths, 81 left ventricular assist device implantations and 107 urgent cardiac transplantations. In univariable Cox regression, increased β-OHB levels (T3 vs. T1: hazard ratio [HR] 1.39, 95% confidence interval [CI] 1.13-1.72, p = 0.002) and elevated FFA levels (T3 vs. T1: HR 1.39, 95% CI 1.09-1.79, p = 0.008) were both predictors of a worse prognosis. In multivariable Cox analysis evaluating the simultaneous associations of FFA and β-OHB levels with outcomes, only FFA levels remained significantly associated with adverse outcomes., Conclusions: In patients with advanced HFrEF, increased plasma β-OHB correlate with FFA levels, worse right ventricular function, greater neurohormonal activation and other markers of HF severity. The association between plasma β-OHB and adverse outcomes is eliminated after accounting for FFA levels, suggesting that increased β-OHB is a consequence reflecting heightened lipolytic state, rather than a cause of worsening HF., (© 2024 European Society of Cardiology.)

Aims: Impaired left ventricular-arterial coupling (VAC) has been shown to correlate with worse prognosis in cardiac diseases and heart failure (HF). The extent of the relationship between VAC and circulating biomarkers associated with HF has been scarcely documented. We aimed to explore associations of VAC with proteins involved in HF pathophysiology within a large population-based cohort of middle-aged individuals., Methods and Results: In the forth visit of the STANISLAS family cohort, involving 1309 participants (mean age 48 ± 14 years; 48% male) from parent and children generations, we analysed the association of 32 HF-related proteins with non-invasively assessed VAC using pulse wave velocity (PWV)/global longitudinal strain (GLS) and arterial elastance (E a )/ventricular end-systolic elastance (E es ). Among the 32 tested proteins, fatty acid-binding protein adipocyte 4, interleukin-6, growth differentiation factor 15, matrix metalloproteinase (MMP)-1, and MMP-9 and adrenomedullin were positively associated with PWV/GLS whereas transforming growth factor beta receptor type 3, MMP-2 and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were negatively associated. In multivariable models, only MMP-2 and NT-proBNP were significantly and inversely associated with PWV/GLS in the whole population and in the parent generation. Higher levels of NT-proBNP were also negatively associated with E a /E es in the whole cohort but this association did not persist in the parent subgroup., Conclusion: Elevated MMP-2 and NT-proBNP levels correlate with better VAC (lower PWV/GLS), possibly indicating a compensatory cardiovascular response to regulate left ventricular pressure amidst cardiac remodelling and overload., (© 2024 The Author(s).

Aims: Iron deficiency (ID) is common in patients with heart failure (HF) and is associated with poor outcomes, regardless of anaemia status. Iron supplementation has been demonstrated to improve exercise capacity and quality of life in patients with HF with an ejection fraction <50% and ID. This survey aimed to provide data on real-world practices related to ID screening and management., Methods and Results: We designed and distributed an online survey (23 questions) regarding ID screening and management in the HF setting. Overall, 256 cardiologists completed the survey (59.8% male, mostly between 30 and 50 years). The majority of physicians defined ID according to the most recent HF recommendations (98.4%) and reported screening for ID in more than half of their patients (68.4%). However, only 54.3% of the respondents performed periodic screening (every 6 months to 1 year). A total of 93.0% of participants prescribed and/or administered iron supplementation, using intravenous iron as the preferred method of administration (86.3%). After iron supplementation, 96.1% of the respondents reassessed ID, most frequently at 3-6 months (67.6%). Most physicians (93.8%) perceived ID as an underestimated comorbidity in HF. Cardiologists' age, training status, subspecialty and work setting (academic vs. non-academic hospitals) were associated with heterogeneity in the answers., Conclusions: The results of this survey highlight the need for more consistent strategies of ID screening and treatment for patients with HF., (© 2024 The Author(s).

Aim: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) has become a common intervention for patients with cardiogenic shock (CS), often complicated by cardiac arrest (CA). Moderate hypothermia (MH) has shown promise in mitigating ischemia-reperfusion injury following CA. The HYPO-ECMO trial aimed to compare the effect of MH versus normothermia in refractory CS rescued by VA-ECMO. The primary aim of this non-predefined post hoc study was to assess the treatment effect of MH in the subgroup of patients with cardiac arrest (CA) within the HYPO-ECMO trial. Additionally, we will evaluate the prognostic significance of CA in these patients., Methods: This post hoc analysis utilized data from the randomized HYPO-ECMO trial conducted across 20 French cardiac shock care centers between October 2016 and July 2019. Participants included intubated patients receiving VA-ECMO for CS for less than 6 h, with 334 patients completing the trial. Patients were randomized to early MH (33-34 °C) or normothermia (36-37 °C) for 24 h., Results: Of the 334 patients, 159 (48%) experienced preceding CA. Mortality in the CA group was 50.9% at 30 days and 59.1% at 180 days, compared to 42.3% and 51.4% in the no-CA group, respectively (adjusted risk difference [RD] at 30 days, 8.1% [-0.8 to 17.1%], p = 0.074 and RD at 180 days 7.0% [-3.0 to 16.9%], p = 0.17). MH was associated with a significant reduction in primary (RD -13.3% [-16.3 to -0.3%], p = 0.031) and secondary outcomes in the CA group only (p < 0.025 for all), with a significant interaction between MH and CA status for 180-day mortality [p = 0.03]., Conclusions: This post hoc analysis suggests that MH shows potential for reducing mortality and composite endpoints in patients with cardiac arrest and refractory CS treated with VA-ECMO without an increased risk of severe bleeding or infection.

Aims: The determinants and relevance of right ventricular (RV) mechanical dyssynchrony in heart failure with reduced ejection fraction (HFrEF) are poorly understood. We hypothesized that increased afterload may adversely affect the synchrony of RV contraction., Methods and Results: A total of 148 patients with HFrEF and 36 controls underwent echocardiography, right heart catheterization, and gated single-photon emission computed tomography to measure RV chamber volumes and mechanical dyssynchrony (phase standard deviation of systolic displacement timing). Exams were repeated after preload (N = 135) and afterload (N = 15) modulation. Patients with HFrEF showed higher RV dyssynchrony compared with controls (40.6 ± 17.5° vs. 27.8 ± 9.1°, P < 0.001). The magnitude of RV dyssynchrony in HFrEF correlated with larger RV and left ventricular (LV) volumes, lower RV ejection fraction (RVEF) and LV ejection fraction, reduced intrinsic contractility, increased heart rate, higher pulmonary artery (PA) load, and impaired RV-PA coupling (all P ≤ 0.01). Low RVEF was the strongest predictor of RV dyssynchrony. Left bundle branch block (BBB) was associated with greater RV dyssynchrony than right BBB, regardless of QRS duration. RV afterload reduction by sildenafil improved RV dyssynchrony (P = 0.004), whereas preload change with passive leg raise had modest effect. Patients in the highest tertiles of RV dyssynchrony had an increased risk of adverse clinical events compared with those in the lower tertile [T2/T3 vs. T1: hazard ratio 1.98 (95% confidence interval 1.20-3.24), P = 0.007]., Conclusions: RV dyssynchrony is associated with RV remodelling, dysfunction, adverse haemodynamics, and greater risk for adverse clinical events. RV dyssynchrony is mitigated by acute RV afterload reduction and could be a potential therapeutic target to improve RV performance in HFrEF., (© 2024 The Authors.

Composite outcomes are commonly used in critical care trials to estimate the treatment effect of an intervention. A significant limitation of classical analytic approaches is that they assign equal statistical importance to each component in a composite, even if these do not have the same clinical importance (i.e., in a composite of death and organ failure, death is clearly more important). The win ratio (WR) method has been proposed as an alternative for trial outcomes evaluation, as it effectively assesses events based on their clinical relevance (i.e., hierarchical order) by comparing each patient in the intervention group with their counterparts in the control group. This statistical approach is increasingly used in cardiovascular outcome trials. However, WR may be useful to unveil treatment effects also in the critical care setting, because these trials are typically moderately sized, thus limiting the statistical power to detect small differences between groups, and often rely on composite outcomes that include several components of different clinical importance. Notably, the advantages of this approach may be offset by several drawbacks (such as ignoring ties and difficulties in selecting and ranking endpoints) and challenges in appropriate clinical interpretation (i.e., establishing clinical meaningfulness of the observed effect size). In this perspective article, we present some key elements to implementing WR statistics in critical care trials, providing an overview of strengths, drawbacks, and potential applications of this method. To illustrate, we conduct a reevaluation of the HYPO-ECMO (Hypothermia during Venoarterial Extracorporeal Membrane Oxygenation) trial using the WR framework as a case example.

Background: Patients with heart failure with reduced ejection fraction (HFrEF) and sinus rhythm have a heightened risk of stroke. Whether anticoagulation benefits these patients is uncertain. In this post hoc analysis of the A Study to Assess the Effectiveness and Safety of Rivaroxaban in Reducing the Risk of Death, Myocardial Infarction, or Stroke in Participants with Heart Failure and Coronary Artery Disease Following an Episode of Decompensated Heart Failure (COMMANDER-HF) trial we evaluated how a previously validated risk model consisting of 3 variables (history of prior stroke, insulin-treated diabetes, and N-terminal pro-B-type natriuretic peptide level) would perform, compared with plasma d-dimer, for stroke prediction and estimation of the benefit of low-dose rivaroxaban., Methods and Results: Stroke risk and treatment effect were computed across risk score and plasma d-dimer tertiles. Risk score was available in 58% of the COMMANDER-HF population (n = 2928). Over a median follow-up of 512 days (range 342-747 days), 60 patients experienced a stroke (14.6 per 1000 patient-years). The risk model did not identify patients at higher risk of stroke and showed a low overall prognostic performance (C-index = 0.53). The effect of rivaroxaban on stroke was homogeneous across risk score tertiles (P-interaction = .67). Among patients in whom the risk score was estimated, d-dimer was available in 2343 (80%). d-dimer had an acceptable discrimination performance for stroke prediction (C-index = 0.66) and higher plasma d-dimer concentrations were associated with higher rates of stroke (ie, tertile 3 vs tertile 1, hazard ratio 3.65, 95% confidence interval 1.59-8.39, P = .002). Treatment with low-dose rivaroxaban reduced the incidence of stroke in patients at highest risk by d-dimer levels (ie, >515 ng/mL, hazard ratio 0.42, 95% confidence interval 0.18-0.95, P-interaction = .074), without any safety concerns., Conclusions: In our analysis, plasma d-dimer concentrations performed better than a previously described 3-variable risk score for stroke prediction in patients with heart failure with reduced ejection fraction, a recent clinical worsening and sinus rhythm as enrolled in the COMMANDER-HF trial. In these patients, a raised plasma d-dimer concentration identified patients who might benefit most from rivaroxaban., Competing Interests: DISCLOSURES L.M. has received lecture fees from AstraZeneca and Vifor.

Aims: Whether aldosterone levels after myocardial infarction (MI) are associated with mid- and long-term left ventricular (LV) remodelling in the era of systematic use of renin-angiotensin system inhibitors is uncertain. We prospectively investigated the relationship between aldosterone levels and mid- and long-term LV remodelling in patients with acute MI., Methods and Results: Plasma aldosterone was measured in 119 patients successfully treated by primary percutaneous coronary angioplasty for a first acute ST-elevation MI (STEMI) 2-4 days after the acute event. LV volumes were assessed by cardiac magnetic resonance (CMR) and transthoracic echocardiography (TTE) in the same timeframe and 6 months later. LV assessment was repeated by TTE 3-9 years after MI (n = 80). The median aldosterone level at baseline was 23.1 [16.8; 33.1] pg/ml. In the multivariable model, higher post-MI aldosterone concentration was significantly associated with more pronounced increase in LV end-diastolic volume index (TTE: β ± standard error [SE]: 0.113 ± 0.046, p = 0.015; CMR: β ± SE: 0.098 ± 0.040, p = 0.015) and LV end-systolic volume index (TTE: β ± SE: 0.083 ± 0.030, p = 0.008; CMR: β ± SE: 0.064 ± 0.032, p = 0.048) at 6-month follow-up, regardless of the method of assessment. This result was consistent also in patients with a LV ejection fraction (LVEF) >40%. The association between baseline plasma aldosterone and adverse LV remodelling did not persist at the 3-9-year follow-up evaluation., Conclusion: Aldosterone concentration in the acute phase was associated with adverse LV remodelling in the medium term, even in the subgroup of patients with LVEF >40%, suggesting a potential role of the mineralocorticoid system in post-MI adverse remodelling. Plasma aldosterone was no longer associated with LV remodelling in the long term (NCT01109225)., (© 2023 The Authors.

Aim: Eplerenone reduces the risk of cardiovascular death or first hospitalization for heart failure (HF) in patients with HF and a reduced ejection fraction (HFrEF), but it is still frequently underused in routine practice. We evaluated the time course of benefits of eplerenone after its initiation in HFrEF patients from the EMPHASIS-HF trial., Methods and Results: The EMPHASIS-HF trial was a double-blind randomized clinical trial assessing the effect of eplerenone in patients (n = 2737, mean age 68.6 ± 7.6 years, 22.3% women) with HFrEF and mild symptoms. The time trajectories for the effect of eplerenone versus placebo on the primary composite endpoint (cardiovascular death or first hospitalization for HF) were investigated using Cox proportional hazards models with truncated data at each day post-randomization. A significant reduction in the primary composite endpoint was observed 26 days after randomization (hazard ratio 0.58; 95% confidence interval, 0.34-1.00, p = 0.049). Eplerenone was first associated with a significant reduction in the primary endpoint in 35 days or less in most subgroups, including patients with HF history ≥18 months (day 24), estimated glomerular filtration rate <60 ml/min (day 12), ischaemic HF aetiology (day 28), age ≥65 years (day 28), narrow QRS (day 30), higher MAGGIC score (day 35), lower potassium (day 30), left ventricular ejection fraction ≥30% (day 28) or already treated with beta-blockers (day 25)., Conclusions: Eplerenone provides statistically significant and clinically meaningful benefits shortly after treatment initiation in most patients, irrespective of clinical profile. This result reinforces the need for an early initiation of eplerenone in HFrEF, as part of rapidly instituting guideline-directed medical therapy., (© 2023 European Society of Cardiology.)

Aims: Left ventricular scar is an arrhythmic substrate that may be missed by echocardiography and diagnosed only by cardiac magnetic resonance (CMR), which is a time-consuming and expensive imaging modality. Premature ventricular complexes (PVCs) with a right-bundle-branch-block (RBBB) pattern are independent predictors of late gadolinium enhancement (LGE) but their positive predictive value is low. We studied which electrocardiographic features of PVCs with an RBBB pattern are associated with a higher probability of the absence of an underlying LGE., Methods: The study included 121 athletes (36 ± 16 years; 48.8% men) with monomorphic PVCs with an RBBB configuration and normal standard clinical investigations who underwent CMR. LGE was identified in 35 patients (29%), predominantly in those with PVCs with a superior/intermediate axis (SA-IntA) compared to inferior axis (IA) (38% vs. 10%, P = 0.002). Among patients with SA-IntA morphology, the contemporary presence of qR pattern in lead aVR and V1 was exclusively found in patients without LGE at CMR (51.0% vs. 0%, P < 0.0001). Among patients with IA, the absence of LGE correlated to a narrow ectopic QRS (145 ± 16 vs. 184 ± 27 msec, P < 0.001)., Conclusions: Among athletes with apparently idiopathic PVCs with a RBBB configuration, the presence of a concealed LGE at CMR was documented in 29% of cases, mostly in those with a SA-IntA. In our experience, the contemporary presence of qR pattern in lead aVR and V1 in PVCs with RBBB/SA-IntA morphology or, on the other hand, a relatively narrow QRS in PVCs with an IA, predicted absence of LGE., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.

There is still the need to lower LDL-c, although the use of statins, ezetimibe and proprotein convertase subtilisin/kexin type 9. Patients with atherosclerotic cardiovascular disease and/or familial hypercholesterolaemia are treated with statins at maximum tolerated dose, with or without further lipid-lowering drugs, but very often, we can't reach the goal, so bempedoic acid treatment lead to a significant reduction in low-density lipoprotein cholesterol, in different groups of patients, with a favourable safety profile., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.

The sodium-glucose co-transporter 2 (SGLT2) inhibitors have been shown to reduce risks of clinical events in patients with heart failure (HF), with early and sustained benefits regardless of ejection fraction, diabetic status, and care setting. As part and parcel of the modern foundational HF therapy, clinicians should be familiar with these drugs, in order to implement their use and limit the potential adverse effects. We present an up-to-date review of current evidence and a practical guide for the prescription of SGLT2 inhibitors in patients with HF, highlighting important elements for patient selection, treatment initiation, dosing, and problem solving., Competing Interests: Conflict of interest: L.M. received speaker fees from AstraZeneca and Vifor Pharma.

Implantable cardiac monitors (ICMs) have found increasing use in clinical practice over the years, proving, when used in high-risk populations, to facilitate the diagnosis of bradyarrhythmias and tachyarrhythmias requiring treatment. Experience with heart failure patients undergoing pacemaker (PMK) or implantable defibrillator (ICD) implantation, which allow for continuous electrocardiographic monitoring and transthoracic impedance assessment, has made it possible to identify predictors of heart failure flare-ups. In this context, the use of telemonitoring has been shown to ensure better management of patients with heart failure. These benefits cannot be assessed to date in patients with heart failure and left ventricular ejection fraction (LVEF) > 35% who have no indication for PMK or ICD implantation. This population has been shown to have a significant incidence of ventricular arrhythmias and bradyarrhythmias. In addition, a significant number of cerebrovascular events are observed in this population, largely attributable to the high incidence of atrial fibrillation (AF). In this population, the occurrence of AF has also been shown to have a negative impact on patients' prognosis; at the same time, a rhythm control strategy has been shown to be more beneficial in this area than a rate control strategy. Studies also suggest arrhythmias have a negative impact on the cognitive status and quality of life of heart failure patients. These reasons could justify the implantation of ICMs equipped with telemonitoring systems in heart failure patients. The information provided by the monitoring system, if properly managed, could bring benefits in terms of prognosis and quality of life along with a reduction in economic costs. We will try here, by answering a few questions, to assess whether there is an indication for ICM in heart failure, which patients should be candidates and how these patients should be managed., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.

Patients with clinically established atherosclerotic cardiovascular disease are at a very high risk of recurrent cardiovascular events. An adequate management of risk factors and the implementation of healthy behaviours significantly decrease the risk of unfavourable clinical outcomes and future cardiovascular events, including death. Patients discharged after an acute coronary syndrome should be managed according to their individual risk level in order to ensure the appropriate treatment. Nevertheless, care pathways should also take into consideration the available resources and the logistical/structural aspects. In this setting, cardiac rehabilitation is prosed as a multidisciplinary approach to improving daily function and reducing cardiovascular risk factors. The organization of a network with the involvement of different medical and non-medical figures is essential to ensure successful outcomes and expected cost-effectiveness., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.

Chronic kidney disease (CKD) is a complex syndrome and a relevant problem of public health due to its large incidence and prevalence and to the high costs for its management. The hallmark of CKD, the progressive reduction in the glomerular filtration rate (eGFR), is strongly associated with an increase in cardiovascular events, such as fatal and non-fatal heart attack, stroke and heart failure, and mortality. Therefore, clinicians should pay any effort for preventing or slowing down the decline of renal function in order to reduce not only the occurrence of critical renal events (the need for dialysis or renal transplantation, among the most dreadful) but also the incidence of cardiovascular events. Accordingly, an early diagnosis and a targeted treatment in patients with kidney disease are crucial to reduce the evolution towards more advanced stages of the disease and the occurrence of complications. For a long time, the therapeutic approach to the majority of CKD patients was based on the strict control of risk factors, such as the diabetic disease and hypertension, together with the use of renin-angiotensin-aldosterone system inhibitors, particularly in the presence of albuminuria. Over time, this strategy proved to be only partially effective, since most CKD patients showed a progressive worsening of renal function. Gliflozins and incretins are novel anti-diabetic drugs that have been demonstrated to slow down the slope of eGFR reduction in patients with CKD, irrespective of diabetic status. Concurrently, these drugs showed to significantly impact cardiovascular prognosis reducing the incidence of clinical events. For their ability to act on a wide spectrum of disease, gliflozins and incretins are also called 'cardio-nephro-metabolic' drugs., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.
