Abstract
BACKGROUND Dapagliflozin and empagliflozin are antidiabetic medications. They are the first two sodium-glucose cotransporter-2 inhibitors (SGLT2i) to receive the US Food and Drug Administration approval to manage heart failure. Emerging new trials have examined changes in the 6-min walk distance as a clinically significant response to dapagliflozin and empagliflozin in patients with heart failure with reduced ejection fraction (HFpEF) and heart failure with preserved ejection fraction (HFrEF). This meta-analysis aims to evaluate the effects of dapagliflozin and empagliflozin on the 6-min walk distance in patients with HFpEF and HFrEF. To our knowledge, no such meta-analysis has been published. METHODS Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched four electronic databases (PubMed, EMBASE, Cochrane Library, and Web of Science) to identify eligible studies reported up to December 16, 2023. Using Review Manager software, we reported outcomes as risk ratios (RRs) or mean difference (MD) and confidence intervals (CIs). A p-value ≤ 0.05 is considered as statistically significant. RESULTS The meta-analysis included a total of 8 studies with 2624 patients. Overall, the results showed insignificant differences in the 6-min walk between the SGLT2i and placebo (MD 24, 95% CI -0.30 to 18.78, p = 0.06). Results became significant after resolving the heterogeneity (MD 6.72, 95% CI 0.13 to 13.31, p = 0.05). Notably, the results of each drug separately were insignificant. More robust observations occurred in the HFpEF group (MD 10.73, 95% CI 1.08 to 20.39, p = 0.03). Compared to placebo, patients on dapagliflozin reported significant improvement in the Kansas City Cardiomyopathy Questionnaire Clinical Summary (KCCQ-CS) and Overall Summary (KCCQ-OS) with values of MD 5.18 (95% CI 2.80 to 7.57, p < 0.0001) and MD 4.06 (95% CI 1.66 to 6.46, p = 0.0009), respectively. The dapagliflozin group and patients with HFpEF had reported a significant reduction in their weight compared with the control group (MD -0.59 CI -1.09 to -0.08, p = 0.02) and (MD -0.80 CI -1.47 to -0.13, p = 0.02), respectively. No significant side effects were observed for dapagliflozin or empagliflozin. CONCLUSION Patients with HFpEF experienced benefits from SGLT2i administration, as evidenced by improved 6-min walk distances and weight reduction. Dapagliflozin demonstrated clinical and overall improvements in KCCQ scores and was more effective in reducing weight than the placebo. Both Dapagliflozin and Empagliflozin were well-tolerated and exhibited favorable safety profiles. Future studies could benefit from a larger patient population, a longer follow-up period, and a broader range of SGLT2i.

Ye Q, Zha K. SGLT2i‑treated heart failure patients with a reduced ejection fraction: A meta‑analysis. Exp Ther Med 2023; 26:548. [PMID: 37928504 PMCID: PMC10623217 DOI: 10.3892/etm.2023.12248] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Accepted: 09/15/2023] [Indexed: 11/07/2023] Open
Abstract
The aim of this study was to investigate the effects of SGLT2 inhibitors (SGLT2i) on patients with heart failure (HF) and reduced ejection fraction, with or without diabetes. A systematic review of randomized controlled trials (RCTs) was conducted, comparing SGLT2i to a placebo for HF patients. Relevant studies from PubMed, Web of Science, and EMBASE were searched from inception to July 2021, without any language restrictions. The pooled effect was estimated using the odds ratio (OR) and 95% confidence interval (CI). Depending on the heterogeneity test results, either random effects or fixed effects models were selected to estimate the pooled effects. Sensitivity analysis was conducted by gradually removing each study to evaluate the results' stability. A total of 5 RCT studies were included in the analysis. The fixed-effects model demonstrated that the patients in the SGLT2i group had a lower risk of hospitalization for HF/cardiovascular death (OR=0.72; 95% CI, 0.67-0.78), P<0.0001; I2=0.0%, P=0.966), cardiovascular death (OR=0.84, 95% CI (0.77, 0.93), P<0.0001; I2=0.0%, P=0.633), hospitalization for HF (OR=0.69, 95% CI (0.63, 0.75), P<0.0001; I2=0.0%, P=0.933), and all-cause mortality (OR=0.79, 95% CI (0.71, 0.89), P<0.0001; I2=3.3%, P=0.376) compared to the placebo group. Sensitivity analysis showed that the pooled effect value remained stable within the corresponding range, even after each study was gradually removed. In conclusion, SGLT2i can reduce the risk of HF hospitalization, cardiovascular death, and all-cause mortality in patients with HF and a reduced ejection fraction, regardless of the presence or absence of diabetes.

Assessment of the Safety, Efficacy, and Benefit of Empagliflozin in Patients With Type 2 Diabetes Mellitus (T2DM) and Heart Failure With Reduced Ejection Fraction (HFrEF) at High Risk for Cardiovascular Events. Cureus 2022; 14:e33070.

Abstract
Background Since the increasing prevalence of type 2 diabetes mellitus (T2DM), heart failure coexisting with it has had a significant impact on clinical management and prognosis. Patients with T2DM and heart failure with reduced ejection fraction (HFrEF) have increased mortality and morbidity. Empagliflozin, a sodium-glucose cotransporter-2 (SGLT2) inhibitor, is widely acknowledged to reduce cardiovascular risk in T2DM patients. We wanted to assess the composite outcomes of heart failure, cardiovascular death, and hospitalization following the start of empagliflozin therapy in the Saudi population. Methods This is a retrospective observational study conducted at King Fahad Armed Forces Hospital-Jeddah. We included patients aged 18 or older, male or female, with T2DM with HFrEF <40% and with a risk of cardiovascular events who were treated with empagliflozin 25 mg once daily as combination therapy and patients using other diabetic agents without empagliflozin as the comparative group. Results A total of 195 patients with T2DM and HFrEF who were at high risk for cardiovascular (CV) events were included in the study. Regarding gender, most of the patients (82.1%) were male with an average age of 61.28 ± 9.92. The patients were divided into 71 individuals who received empagliflozin and 124 who did not. When comparing the surgical procedure and comorbid status of the patients, coronary artery bypass graft (1.4%), coronary artery disease (5.6%), dyslipidemia (5.6%), and ischemic cardiomyopathy (0%) were found compared to the non-empagliflozin group. Meanwhile, hypertension was found to be 71.8% and ischemic heart disease was 50.7% in empagliflozin patients. Furthermore, only dyslipidemia differed significantly (p <0.001) between the empagliflozin and non-empagliflozin groups of patients. However, no significant differences were observed between the average low-density lipoprotein (p = 0.990) and high-density lipoprotein (p = 0.399). There was no significant difference observed in the primary outcome of CV deaths or hospital admission of patients between empagliflozin and non-empagliflozin. No deaths were reported in either of the comparative groups in our study. Conclusion In this study, there was no significant difference observed in hospital admission of the patients between the empagliflozin and non-empagliflozin groups. No cardiovascular mortality was reported in the study population. Further matched group comparative studies or placebo-controlled studies are required to compare the existing evidence of the impact of empagliflozin on T2DM patients with HFrEF and at high risk for CV deaths or hospital admission.

Efficacy and Safety of Empagliflozin in Type 2 Diabetes Mellitus Saudi Patients as Add-On to Antidiabetic Therapy: A Prospective, Open-Label, Observational Study. J Clin Med 2022; 11:jcm11164769. [PMID: 36013008 PMCID: PMC9410062 DOI: 10.3390/jcm11164769] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 08/10/2022] [Accepted: 08/12/2022] [Indexed: 11/17/2022] Open
Abstract
The Saudi Food and Drug Authority (SFDA) approved sodium-glucose cotransporter-2 (SGLT2) inhibitors in 2018. The efficacy and safety of empagliflozin (EMPA) have been confirmed in the U.S., Europe, and Japan for patients with type 2 diabetes mellitus (T2DM); however, analogous evidence is lacking for Saudi T2DM patients. Therefore, the current study aimed to assess the efficacy and safety of EMPA in Saudi patients (n = 256) with T2DM. This is a 12-week prospective, open-label, observational study. Adult Saudi patients with T2DM who had not been treated with EMPA before enrolment were eligible. The exclusion criteria included T2DM patients less than 18 years of age, adults with type one diabetes, pregnant women, paediatric population. The results related to efficacy included a significant decrease in haemoglobin A1c (HbA1c) (adjusted mean difference −0.93% [95% confidence interval (CI) −0.32, −1.54]), significant improvements in fasting plasma glucose (FPG) (−2.28 mmol/L [95% CI −2.81, −1.75]), and a reduction in body weight (−0.874 kg [95% CI −4.36, −6.10]) following the administration of 25 mg of EMPA once daily as an add-on to ongoing antidiabetic therapy after 12 weeks. The primary safety endpoints were the change in the mean blood pressure (BP) values, which indicated significantly reduced systolic and diastolic BP (−3.85 mmHg [95% CI −6.81, −0.88] and −0.06 mmHg [95% CI −0.81, −0.88], respectively) and pulse rate (−1.18 [95% CI −0.79, −3.15]). In addition, kidney function was improved, with a significant reduction in the urine albumin/creatinine ratio (UACR) (−1.76 mg/g [95% CI −1.07, −34.25]) and a significant increase in the estimated glomerular filtration rate (eGFR) (3.54 mL/min/1.73 m2 [95% CI 2.78, 9.87]). Furthermore, EMPA reduced aminotransferases (ALT) in a pattern (reduction in ALT > AST). The adjusted mean difference in the change in ALT was −2.36 U/L [95% CI −1.031, −3.69], while it was −1.26 U/L [95% CI −0.3811, −2.357] for AST and −1.98 U/L [95% CI −0.44, −3.49] for GGT. Moreover, in the EMPA group, serum high-density lipoprotein (HDL) significantly increased (0.29 mmol/L [95% CI 0.74, 0.15]), whereas a nonsignificant increase was seen in low-density lipoprotein (LDL) (0.01 mmol/L [95% CI 0.19, 0.18]) along with a significant reduction in plasma triglyceride (TG) levels (−0.43 mmol/L [95% CI −0.31, −1.17]). Empagliflozin once daily is an efficacious and tolerable strategy for treating Saudi patients with insufficiently controlled T2DM as an add-on to ongoing antidiabetic therapy.

Abstract
Several recent cardiovascular trials of SGLT 2 (sodium-glucose cotransporter 2) inhibitors revealed that they could reduce adverse cardiovascular events in patients with T2DM (type 2 diabetes mellitus). However, the exact molecular mechanism underlying the beneficial effects that SGLT2 inhibitors have on the cardiovascular system is still unknown. In this review, we focus on the molecular mechanisms of the mitochondria-mediated beneficial effects of SGLT2 inhibitors on the cardiovascular system. The application of SGLT2 inhibitors ameliorates mitochondrial dysfunction, dynamics, bioenergetics, and ion homeostasis and reduces the production of mitochondrial reactive oxygen species, which results in cardioprotective effects. Herein, we present a comprehensive overview of the impact of SGLT2 inhibitors on mitochondria and highlight the potential application of these medications to treat both T2DM and cardiovascular diseases.

Abstract
Chemotherapy and targeted therapies have significantly improved the prognosis of oncology patients. However, these antineoplastic treatments may also induce adverse cardiovascular effects, which may lead to acute or delayed onset of cardiac dysfunction. These common cardiovascular complications, commonly referred to as cardiotoxicity, not only may require the modification, suspension, or withdrawal of life-saving antineoplastic therapies, with the risk of reducing their efficacy, but can also strongly impact the quality of life and overall survival, regardless of the oncological prognosis. The onset of cardiotoxicity may depend on the class, dose, route, and duration of administration of anticancer drugs, as well as on individual risk factors. Importantly, the cardiotoxic side effects may be reversible, if cardiac function is restored upon discontinuation of the therapy, or irreversible, characterized by injury and loss of cardiac muscle cells. Subclinical myocardial dysfunction induced by anticancer therapies may also subsequently evolve in symptomatic congestive heart failure. Hence, there is an urgent need for cardioprotective therapies to reduce the clinical and subclinical cardiotoxicity onset and progression and to limit the acute or chronic manifestation of cardiac damages. In this review, we summarize the knowledge regarding the cellular and molecular mechanisms contributing to the onset of cardiotoxicity associated with common classes of chemotherapy and targeted therapy drugs. Furthermore, we describe and discuss current and potential strategies to cope with the cardiotoxic side effects as well as cardioprotective preventive approaches that may be useful to flank anticancer therapies.
