The effect of sodium-glucose cotransporter-2 inhibitors on cardiac structure remodeling and function: A meta-analysis of randomized controlled trials

Impact of SGLT2 inhibitors on cardiovascular outcomes and metabolic events in Chinese han patients with chronic heart failure

OBJECTIVE

This study aimed to evaluate the real-world impact of sodium-glucose cotransporter 2 inhibitors (SGLT2i) on the efficacy, safety, and metabolic profiles of patients with chronic heart failure (CHF), both with and without type 2 diabetes mellitus (T2DM).

METHODS

A cohort of 1,130 patients with reduced ejection fraction chronic heart failure (HFrEF) was recruited from Zhongnan Hospital of Wuhan University, spanning January 2021 to August 2023. Among these, 154 patients received SGLT2i therapy, while 131 patients were assigned to a non-SGLT2i group, following specified inclusion and exclusion criteria. The association between SGLT2i therapy and the risk of primary and secondary endpoints was analyzed, alongside the effect of guideline-recommended heart failure medications at varying dosages on Major Adverse Cardiovascular Events (MACE).

RESULTS

SGLT2i treatment led to reductions in blood pressure, uric acid, NT-proBNP, and pulmonary artery pressure, while increasing body mass index (BMI) and left ventricular ejection fraction (LVEF) in CHF patients. Multivariate Cox regression analysis revealed that SGLT2i therapy reduced the primary endpoint risk by 40.3% (HR 0.597, 95% CI 0.356-0.973, p = 0.047). Univariate Cox regression indicated that SGLT2i might also reduce the incidence of new diagnoses of atrial fibrillation, non-fatal acute myocardial infarction, and MACE in CHF patients. Moreover, the use of a four-drug combination for heart failure management was associated with a lower risk of MACE compared to monotherapy.

CONCLUSION

SGLT2i therapy not only enhances LVEF but also significantly reduces ambulatory blood pressure, uric acid, fasting blood glucose, pulmonary artery pressure, and NT-proBNP levels in CHF patients. Additionally, SGLT2i improves prognosis by lowering the risk of both primary and secondary endpoints. Compared to monotherapy, a four-drug regimen for CHF substantially reduces the risk of MACE, supporting the effectiveness of comprehensive treatment strategies.

Cardio-renal protective effect and safety of sodium-glucose cotransporter 2 inhibitors for chronic kidney disease patients with eGFR < 60 mL/min/1.73 m2: a systematic review and meta-analysis

OBJECTIVE

This meta-analysis was designed to investigate cardio-renal outcomes and safety of sodium-glucose cotransporter-2 inhibitors (SGLT2i) as a therapeutic option among chronic kidney disease(CKD) patients with GFR < 60 mL/min/1.73 m2, regardless of their diabetic status.

METHOD

We conducted a full-scale search from MEDLINE, EMBASE and the Cochrane Library database to identify eligible studies up to Jun 2024. All randomized controlled trials (RCTs) comparing cardio-renal outcomes and/or safety of SGLT2i in CKD patients with eGFR < 60 mL/min/1.73 m2 were involved. The relative risk (RR) and 95% confidence interval (CI) for primary outcomes and adverse events were computed by random-effects mode. We used I2 statistic to analyze heterogeneity. Publication bias was assessed by Egger's test.

RESULTS

Our study incorporated 17 RCTS, including 27,928 patients. In CKD patients with eGFR < 60 mL/min/1.73 m2, SGLT2i decreased risks of cardiovascular events (seven studies, 17,355 participants, RR 0.77, 95% CI 0.70-0.84), hospitalization for heart failure (HHF) (seven studies, 17,869 participants, RR 0.73, 95% CI 0.65-0.82), cardiovascular death (eight studies, 23,079 participants, RR 0.81, 95% CI 0.74 to 0.88) and renal composite outcomes (eight studies, 22,525 participants, RR 0.70, 95% CI 0.61-0.80) with lower risks of any serious adverse effects(fourteen studies, 19,654 participants, RR 0.91, 95% CI 0.87-0.95), hypoglycemia (nine studies, 16,412 participants, RR 0.91, 95% CI 0.84-0.98), hyperkalemia (four studies, 2693 participants, RR 0.68, 95% CI 0.51-0.93) and acute renal injury (five studies, 5424 participants, RR 0.79, 95% CI 0.65-0.95) compared to placebo. SGLT2i also slowed eGFR decline (total slopes: five studies, 10,370 participants, mean difference 1.17, 95%CI 0.86-1.49; chronic slopes: four studies, 8459 participants, mean difference 2.12, 95%CI 1.64-2.61). Further subgroup analyses revealed that SGLT2i decreased relative risks of cardiovascular outcomes(three studies, 1075 participants, RR 0.76, 95% CI 0.54-0.82), HHF(four studies, 1280 participants, RR 0.74, 95% CI 0.55-1.00) and renal composite outcomes (six studies,4375 participants, RR 0.78, 95% CI 0.68-0.88) with no increased adverse events in the CKD 4 patients.

CONCLUSIONS

SGLT2i significantly improved cardio-renal outcomes and were generally safe in CKD patients with eGFR < 60 mL/min/1.73 m2 and with eGFR < 30 mL/min/1.73 m2. Future large-scale RCTs are needed to confirm the robustness of these results.

Dapagliflozin Effects on Left Ventricular Remodeling and Filling Pressures in Heart Failure With Reduced Ejection Fraction

AIMS

The benefits of sodium glucose cotransporter 2 inhibitors in patients with heart failure with reduced ejection fraction (HFrEF) have been clearly demonstrated in randomized clinical trials. However, the mechanisms of the observed beneficial effects remain incompletely understood. This study aimed to assess morphofunctional cardiac changes following dapagliflozin introduction in stable outpatients with HFrEF and to investigate whether these changes were determinants of the improved clinical outcome.

METHODS

In this multicenter, prospective observational study, 300 consecutive HFrEF patients ≥18 years old on optimized medical therapy and eligible for dapagliflozin therapy were enrolled between April 2022 and January 2023. Laboratory and echocardiographic assessments were performed at baseline and after a median of 6 months.

RESULTS

Following dapagliflozin initiation, 47% of patients achieved a target of improvement in left ventricular end-diastolic volume (Δ EDVi < -10%) and/or end-systolic volume (Δ ESVi < -15%) and/or ejection fraction (Δ EF% > 10%) at 6 months. The proportion of patients with elevated left ventricular filling pressures decreased from 26% to 3% at 6 months (P < .001). The combination of left ventricular remodeling and filling pressures improvements was associated with absence of heart failure-related hospitalizations and significant natriuretic peptide reduction at 12 months.

CONCLUSIONS

Dapagliflozin determined left ventricular remodeling and improved left ventricular filling pressures in a high proportion of patients with stable HFrEF patients already on optimized medical therapy. These improvements were associated with absence of heart failure--related hospitalizations and a significant natriuretic peptide reduction at 12 months.

The effect of Empagliflozin on echocardiographic parameters in diabetic patients after acute myocardial infarction: A systematic review and meta-analysis with trial sequential analysis

Patients with diabetes mellitus (DM) are at higher risk of cardiovascular events, particularly acute myocardial infarction (MI). Sodium-glucose cotransporter 2 inhibitors (SGLT2i) can improve cardiac outcomes among heart failure individuals, however, the effects on acute myocardial infarction remain unclear. This meta-analysis investigates the impact of empagliflozin in diabetic patients following acute myocardial infarction. We comprehensively searched PubMed, Scopus, Cochrane, and Web of Science through August 10th, 2023. We included studies comparing empagliflozin versus placebo in diabetes patients with acute myocardial infarction. We used Revman to report the data as mean difference (MD) and 95% confidence interval (CI), and our effect size with a random effects model. Additionally, we performed Trial Sequential Analysis (TSA) to test the robustness of the results. The study protocol was published on PROSPERO with ID: CRD42023447733. Five studies with a total of 751 patients were included in our analysis. Empagliflozin was effective to improve LVEF% (MD: 1.80, 95% CI [0.50, 3.10], p = 0.007), left ventricular end-diastolic volume (LVEDV) (MD: -9.93, 95% CI [-16.07, -3.80], p = 0.002), and left ventricular end-systolic volume (LVESV) (MD: -7.91, 95% CI [-11.93, -3.88], p = 0.0001). However, there was no difference between empagliflozin and placebo groups in terms of NT-pro BNP (MD: - 136.59, 95% CI [-293.43, 20.25], p = 0.09), and HbA1c (MD: -0.72, 95% CI [-1.73, 0.29], p = 0.16). Additionally, empagliflozin did not prevent hospitalization due to heart failure (RR: 0.59, 95% CI [0.16, 2.24], p = 0.44, I-squared = 0%), and mortality (RR: 1.34, 95% CI [0.15,11.90], p = 0.79, I-squared = 25%). Empagliflozin initiation in diabetic patients following acute MI may improve echocardiographic parameters. However, empagliflozin might not be effective in heart failure prevention and optimal glycemic control in this patient population. Further large-scale trials are warranted to ascertain our findings.

Sodium-glucose cotransporter 2 inhibitors and renin-angiotensin-aldosterone system, possible cellular interactions and benefits

Sodium glucose cotransporter 2 inhibitors (SGLT2is) are a newly developed class of anti-diabetics which exert potent hypoglycemic effects in the diabetic milieu. However, the evidence suggests that they also have extra-glycemic effects. The renin-angiotensin-aldosterone system (RAAS) is a hormonal system widely distributed in the body that is important for water and electrolyte homeostasis as well as renal and cardiovascular function. Therefore, modulating RAAS activity is a main goal in patients, notably diabetic patients, which are at higher risk of complications involving these organ systems. Some studies have suggested that SGLT2is have modulatory effects on RAAS activity in addition to their hypoglycemic effects and, thus, these drugs can be considered as promising therapeutic agents for renal and cardiovascular disorders. However, the exact molecular interactions between SGLT2 inhibition and RAAS activity are not clearly understood. Therefore, in the current study we surveyed the literature for possible molecular mechanisms by which SGLT2is modulate RAAS activity.

A review of therapeutic approaches for post-infarction left ventricular remodeling

Left ventricular remodeling is an adaptive process initially developed in response to acute myocardial infarction (AMI), but it ends up with negative adverse outcomes such as infarcted wall thinning, ventricular dilation, and cardiac dysfunction. A prolonged excessive inflammatory reaction to cardiomyocytes death and necrosis plays the crucial role in the pathophysiological mechanisms. The pharmacological treatment includes nitroglycerine, β-blockers, ACEi/ARBs, SGLT2i, mineralocorticoid receptor antagonists, and some miscellaneous aspects. Stem cells therapy, CD34+ cells transplantation and gene therapy constitute the promissing therapeutic approaches for post AMI cardiac remodeling, thereby enhancing angiogenesis, cardiomyocytes differenciation and left ventricular function on top of inhibiting apoptosis, inflammation, and collagen deposition. All these lead to reduce infarct size, scar formation and myocardial fibrosis.

Impact of left ventricular diastolic function and direct oral anticoagulant use for predicting embolic events in patients with heart failure and atrial fibrillation

Background

Patients with atrial fibrillation (AF) and heart failure (HF) have high stroke risk owing to left atrial dysfunction. However, anticoagulation is a concern in patients with high bleeding risk. We aimed to identify independent predictors of stroke in HF patients with AF.

Methods

We retrospectively examined 320 patients (mean age 79 ± 12 years, 163 women) hospitalized with acute HF complicated by AF between January 2014 and December 2018. Patients were followed from admission until ischemic stroke or systemic embolism (SSE) onset or death or were censored at the last contact date or September 2023.

Results

SSE occurred in 40 patients (median follow-up of 528 days). Multivariate Cox regression analysis identified age (hazard ratio [HR] 1.04, 95% confidence interval [CI] 1.00-1.07, p = .034), direct oral anticoagulant (DOAC) use (HR 0.26, 95% CI 0.11-0.60, p = .002), and early diastolic peak flow velocity to early diastolic peak annular velocity (E/e'; HR 1.05, 95% CI 1.02-1.08, p < .001) to be independent predictors of SSE, whereas left atrial reservoir strain was not. After determining an appropriate E/e' cutoff by receiver-operating characteristic curve analysis and adjusting the multivariate Cox model, E/e' ≥17.5 (HR 3.30, 95% CI 1.56-6.83, p = .001) independently predicted SSE. The results were consistent with no interaction in the subanalysis except for gender.

Conclusion

Elderly patients not on DOACs with elevated E/e' may be at higher risk of stroke, suggesting that DOACs should be the first choice for patients with elevated E/e' and aggressive additional prophylaxis and careful follow-up are needed.

The effect of glucagon-like peptide-1 receptor agonists on cardiac function and structure in patients with or without type 2 diabetes mellitus: An updated systematic review and meta-analysis

AIMS

To conduct an updated systematic review and meta-analysis to evaluate the efficacy of glucagon-like peptide-1 receptor agonists (GLP-1RAs) with regard to cardiac function and structure in people with or without type 2 diabetes mellitus (T2DM).

MATERIALS AND METHODS

We conducted a systematic search using the PubMed, Embase and ClinicalTrials.gov online databases. The primary outcome of interest was changes in mitral inflow E-velocity to tissue Doppler e' velocity (E/e') ratio. Secondary outcomes included other indicators of cardiac reverse remodelling and functional capacity comprising changes in left ventricular mass (LVM), left ventricular global longitudinal strain, left ventricular end-diastolic volume, left ventricular end-systolic volume, left ventricular ejection fraction (LVEF), early to atrial mitral inflow velocity ratio, left atrial volume (LAV), N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and 6-min walk test (6MWT) results.

RESULTS

A total of 15 trials involving 898 patients were included in this analysis. GLP-1RAs significantly improved E/e' ratio (mean difference [MD] = -0.73; 95% confidence interval [CI] -1.34, -0.13), LVM (MD = -3.86 g; 95% CI -7.60, -0.12), LAV (MD = -8.20 mL; 95% CI -12.37, -4.04), NT-proBNP level (standardized MD = -0.27; 95% CI -0.47, -0.06), and 6MWT result (MD = +22.31 m; 95% CI 1.64, 42.99). However, GLP-1RAs had no effect on LVEF (MD = +0.31%; 95% CI -1.02, 1.64).

CONCLUSIONS

In this systematic review and meta-analysis, GLP-1RAs were found to have a positive impact on left ventricle diastolic function, hypertrophy, and exercise capacity, but had no effect on systolic function.

Transient Left Ventricular Dysfunction from Cardiomyopathies to Myocardial Viability: When and Why Cardiac Function Recovers

Transient left ventricular dysfunction (TLVD), a temporary condition marked by reversible impairment of ventricular function, remains an underdiagnosed yet significant contributor to morbidity and mortality in clinical practice. Unlike the well-explored atherosclerotic disease of the epicardial coronary arteries, the diverse etiologies of TLVD require greater attention for proper diagnosis and management. The spectrum of disorders associated with TLVD includes stress-induced cardiomyopathy, central nervous system injuries, histaminergic syndromes, various inflammatory diseases, pregnancy-related conditions, and genetically determined syndromes. Furthermore, myocardial infarction with non-obstructive coronary arteries (MINOCA) origins such as coronary artery spasm, coronary thromboembolism, and spontaneous coronary artery dissection (SCAD) may also manifest as TLVD, eventually showing recovery. This review highlights the range of ischemic and non-ischemic clinical situations that lead to TLVD, gathering conditions like Tako-Tsubo Syndrome (TTS), Kounis syndrome (KS), Myocarditis, Peripartum Cardiomyopathy (PPCM), and Tachycardia-induced cardiomyopathy (TIC). Differentiation amongst these causes is crucial, as they involve distinct clinical, instrumental, and genetic predictors that bode different outcomes and recovery potential for left ventricular function. The purpose of this review is to improve everyday clinical approaches to treating these diseases by providing an extensive survey of conditions linked with TLVD and the elements impacting prognosis and outcomes.

Guarding the heart: How SGLT-2 inhibitors protect against chemotherapy-induced cardiotoxicity: SGLT-2 inhibitors and chemotherapy-induced cardiotoxicity

The introduction of chemotherapy agents has significantly transformed cancer treatment, with anthracyclines being one of the most commonly used drugs. While these agents have proven to be highly effective against various types of cancers, they come with complications, including neurotoxicity, nephrotoxicity, and cardiotoxicity. Among these side effects, cardiotoxicity is the leading cause of morbidity and mortality, with anthracyclines being the primary culprit. Chemotherapy medications have various mechanisms that can lead to cardiac injury. Hence, numerous studies have been conducted to decrease the cardiotoxicity of these treatments. Combination therapy with beta-blockers, Angiotensin-converting enzyme inhibitors, and angiotensin receptor blockers have effectively reduced such outcomes. However, a definitive preventive strategy is yet to be established. Meanwhile, sodium-glucose co-transporter-2 (SGLT-2) inhibitors lower blood glucose levels in type 2 diabetes by reducing its re-absorption in the kidneys. They are thus considered potent drugs for glycemic control and reduction of cardiovascular risks. Recent studies have shown that SGLT-2 inhibitors are crucial in preventing chemotherapy-induced cardiotoxicity. They enhance heart cell viability, prevent degenerative changes, stimulate autophagy, and reduce cell death. This drug class also reduces inflammation by inhibiting reactive oxygen species and inflammatory cytokine production. Moreover, it can not only reverse the harmful effects of anticancer agents on the heart structure but also enhance the effectiveness of chemotherapy by minimizing potential consequences on the heart. In conclusion, SGLT-2 inhibitors hold promise as a therapeutic strategy for protecting cancer patients from chemotherapy-induced heart damage and improving cardiovascular outcomes.

The effect of sodium-glucose cotransporter 2 inhibitors on left cardiac remodelling in heart failure with reduced ejection fraction: Systematic review and meta-analysis

AIMS

The therapeutic mechanism of sodium-glucose cotransporter 2 inhibitors (SGLT2i) on left cardiac remodelling in patients with heart failure with reduced ejection fraction (HFrEF) is not well-established. This study meta-analysed the impact of SGLT2i on left cardiac structure and function in patients with HFrEF.

METHODS AND RESULTS

Online databases were queried up to April 2023 for trials reporting indicators of left cardiac structure and function in patients with HFrEF treated with SGLT2i. Data from studies were pooled using a random-effects model to derive weighted mean differences (WMDs) and 95% confidence intervals (CIs). Six trials were included (n = 555). Compared with control, SGLT2i significantly improved left ventricular end-diastolic volume (LVEDV; WMD: -17.07 ml [-23.84, -10.31]; p < 0.001), LVEDV index (WMD: -5.62 ml/m2 [-10.28, -0.97]; p = 0.02), left ventricular end-systolic volume (LVESV; WMD: -15.63 ml [-26.15, -5.12]; p = 0.004), LVESV index (WMD: -6.90 ml/m2 [-10.68, -3.11]; p = 0.001), left ventricular ejection fraction (WMD: 2.71% [0.70, 4.72]; p = 0.008), and left atrial volume index (WMD: -2.19 ml/m2 [-4.26, -0.11]; p = 0.04) in patients with HFrEF. SGLT2i use was associated with a non-significant trend towards a reduction in left ventricular mass index (WMD: -6.25 g/m2 [-12.79, 0.28]; p = 0.06). No significant impact on left ventricular global longitudinal strain was noted (WMD: 0.21% [-0.25, 0.67]; p = 0.38).

CONCLUSIONS

Sodium-glucose cotransporter 2 inhibitors improve cardiac structure and function in patients with HFrEF.

Role of Sodium-Glucose Co-Transporter-2 Inhibitor During Anthracycline Use: An Updated Review

The coalescence of anthracycline-induced cardiotoxicity and the evolving role of sodium-glucose co-transporter-2 (SGLT-2) inhibitors in oncology and cardiology has prompted a comprehensive review of their mechanisms, clinical implications, and future directions. Anthracyclines, potent chemotherapeutic agents, have been integral in cancer treatment, yet their potential for cardiac harm necessitates careful monitoring and management. We explore the multifactorial nature of anthracycline-induced cardiotoxicity, encompassing diverse patient populations, cumulative doses, and interplay with other treatments. While advancements in imaging and biomarker assessments aid in early detection, the lack of standardized criteria poses challenges. The emergent role of SGLT-2 inhibitors, initially developed for diabetes management, presents a novel avenue for cardioprotection. Beyond glycemic control, these inhibitors exhibit pleiotropic effects, including enhanced diuresis, anti-inflammatory actions, and modulation of energy sources. Consequently, SGLT-2 inhibitors are being investigated for their potential to mitigate cardiotoxic effects, promising an innovative approach in cardio-oncology. Despite these advancements, limitations in data interpretation and patient-specific considerations persist. The future of anthracycline-induced cardiotoxicity research lies in predictive biomarkers, precision medicine, multidisciplinary collaboration, and tailored treatment regimens. By navigating these challenges and harnessing emerging strategies, we aim to optimize cancer treatment efficacy while safeguarding cardiovascular health, ultimately paving the way for a new era of personalized and comprehensive oncologic care.

Impact of SGLT2 Inhibitors on Left Ventricular Remodeling in Diabetic Patients with Acute Myocardial Infarction

OBJECTIVE

To assess the effect of sodium-glucose cotransporter 2 inhibitors (SGLT2-I) on cardiac remodeling and prognosis in type 2 diabetes mellitus (T2DM) patients presenting with acute myocardial infarction (AMI).

METHODS

In this single-center retrospective active-comparator study, consecutive diabetic AMI patients undergoing percutaneous coronary intervention (PCI) between 2021 and 2023 were enrolled. Patients were divided into SGLT2-I users and non-SGLT2-I users based on discharge medications. The primary endpoint was the left ventricular remodeling index (LVRI), defined as the relative change in LV end-diastolic volume after six months. The secondary outcomes included major adverse cardiovascular events (MACE), comprising all-cause mortality, hospitalization for heart failure, nonfatal MI, and nonfatal stroke.

RESULTS

The study comprised 423 T2DM AMI patients(with or without ST-segment elevation), with 239 SGLT2-I users and 184 non-SGLT2-I users. At six months, LVRI was significantly lower in the SGLT2-I users compared to the non-SGLT2-I users (3.49 ± 19.71 vs 7.06 ± 15.15, P = .042). The non-SGLT2-I users exhibited a higher prevalence of positive LVR (LVRI > 0%) (64.67% vs 50.63%, P = .004) and pathological LVR (LVRI > 20%) (19.57% vs 12.13%, P = .036). Multivariate logistic regression indicated that SGLT2-I was associated with a reduced risk of LVR (OR 0.6; 95%CI 0.38-0.97; P = .035). During a mean follow-up of 25 ± 8 months, Kaplan-Meier analysis demonstrated a lower rate of MACE-free survival in the non-SGLT2-I users (P = .005).

CONCLUSIONS

SGLT2-I protects against LVR and lowers the risk of adverse cardiovascular outcomes in T2DM AMI patients.

Sizing SGLT2 Inhibitors Up: From a Molecular to a Morpho-Functional Point of View

Sodium-glucose cotransporter 2 inhibitors (SGLT2i), or gliflozins, have recently been shown to reduce cardiovascular death and hospitalization in patients with heart failure, representing a revolutionary therapeutic tool. The purpose of this review is to explore their multifaceted mechanisms of actions, beyond their known glucose reduction power. The cardioprotective effects of gliflozins seem to be linked to the maintenance of cellular homeostasis and to an action on the main metabolic pathways. They improve the oxygen supply for cardiomyocytes with a considerable impact on both functional and morphological myocardial aspects. Moreover, multiple molecular actions of SGLT2i are being discovered, such as the reduction of both inflammation, oxidative stress and cellular apoptosis, all responsible for myocardial damage. Various studies showed controversial results concerning the role of SGLT2i in reverse cardiac remodeling and the lowering of natriuretic peptides, suggesting that their overall effect has yet to be fully understood. In addition to this, advanced imaging studies evaluating the effect on all four cardiac chambers are lacking. Further studies will be needed to better understand the real impact of their administration, their use in daily practice and how they can contribute to benefits in terms of reverse cardiac remodeling.

Impact of dapagliflozin on cardiac remodelling in patients with chronic heart failure: The DAPA-MODA study

AIMS

Dapagliflozin improves the prognosis of patients with heart failure (HF), regardless of left ventricular ejection fraction (LVEF). However, its effect on cardiac remodelling parameters, specifically left atrial (LA) remodelling, is not well established.

METHODS AND RESULTS

The DAPA-MODA trial (NCT04707352) is a multicentre, single-arm, open-label, prospective and interventional study that aimed to evaluate the effect of dapagliflozin on cardiac remodelling parameters over 6 months. Patients with stable chronic HF receiving optimized guideline-directed therapy, except for any sodium-glucose cotransporter 2 inhibitor, were included. Echocardiography was performed at baseline, 30 and 180 days, and analysed by a central core-lab in a blinded manner to both patient and time. The primary endpoint was the change in maximal LA volume index (LAVI). A total of 162 patients (64.2% men, 70.5 ± 10.6 years, 52% LVEF >40%) were included in the study. At baseline, LA dilatation was observed (LAVI 48.1 ± 22.6 ml/m2 ) and LA parameters were similar between LVEF-based phenotypes (≤40% vs. >40%). LAVI showed a significant reduction at 180 days (-6.6% [95% confidence interval -11.1, -1.8], p = 0.008), primarily due to a decrease in reservoir volume (-13.8% [95% confidence interval -22.5, -4], p = 0.007). Left ventricular geometry improved with significant reductions in left ventricular mass index (-13.9% [95% confidence interval -18.7, -8.7], p < 0.001), end-diastolic volume (-8.0% [95% confidence interval -11.6, -4.2], p < 0.001) and end-systolic volume (-11.9% [95% confidence interval -16.7, -6.8], p < 0.001) at 180 days. N-terminal pro-B-type natriuretic peptide (NT-proBNP) showed a significant reduction at 180 days (-18.2% [95% confidence interval -27.1, -8.2], p < 0.001), without changes in filling Doppler measures.

CONCLUSION

Dapagliflozin administration in stable out-setting patients with chronic HF and optimized therapy results in global reverse remodelling of cardiac structure, including reductions in LA volumes and improvement in left ventricular geometry and NT-proBNP concentrations.
