Aims: Sodium-glucose co-transporter 2 (SGLT2) inhibitors are novel oral hypoglycemic agents strongly endorsed in the treatment guidelines for heart failure due to their cardioprotective benefits. However, their specific impact of SGLT2 inhibitors on arrhythmias incompletely understood. This systematic review and meta-analysis aimed to comprehensively evaluate the long-term effects of SGLT2 inhibitors on various arrhythmia types.

Methods: We systematically searched PubMed, Embase, Web of Science, and ClinicalTrials.gov from database inception to 30 June 2024, to identify randomized controlled clinical trials (RCTs) with a follow-up duration of at least 52 weeks. The primary outcome of the meta-analysis was atrial fibrillation (AF) or atrial flutter (AFL), and the secondary outcomes included ventricular tachycardia (VT), ventricular fibrillation (VF), and sinus bradycardia. The pooled risk ratios (RRs) with 95% confidence intervals (CIs) were used to estimate the incidence of arrhythmias.

Results: Thirty-nine RCTs involving 107,770 participants were included. The results of meta-analysis revealed that patients treated with SGLT2 inhibitors had a reduced risk of AF/AFL compared with placebo (RR 0.86; 95%CI, 0.77–0.95; I2 = 0%; P = 0.003). There was no significant difference in the risk of AF/AFL between the high-dose SGLT2 inhibitors group and the low-dose SGLT2 inhibitors group (RR 0.78; 95%CI, 0.60–1.02; I2 = 0%; P = 0.07), although a decreasing trend in the high-dose group was noted. Similarly, no significant differences were found for VT (RR 0.99; 95%CI, 0.81–1.22; I2 = 0%; P = 0.96), VF (RR 1.06; 95%CI, 0.73–1.54; I2 = 0%; P = 0.75) or sinus bradycardia (RR 1.12; 95%CI, 0.57–2.18; I2 = 0%; P = 0.74) between the SGLT2 inhibitors and placebo groups.

Conclusion: SGLT2 inhibitors significantly reduce the risk of AF/AFL but have no notable impact on the risk of VT, VF, and sinus bradycardia. Additionally, different doses of SGLT2 inhibitors did not statistically influence AF/AFL incidence.

1 Introduction

Sodium-glucose co-transporter 2 (SGLT2) inhibitors are novel oral hypoglycemic agents, whose cardioprotective effects have been explored extensively in recent years (Wei and Du, 2023). The 2021 ESC Guidelines for the Management and Treatment of Acute and Chronic Heart Failure recommended SGLT2 inhibitors for patients with type 2 diabetes mellitus (T2DM) at risk of cardiovascular (CV) events, citing their ability to reduce heart failure (HF) hospitalization, major CV events, and CV death. In the absence of contraindications and when tolerated, dapagliflozin or empagliflozin is endorsed for patients with HFrEF, regardless of diabetes status (Mcdonagh et al., 2022). More recently, SGLT2 inhibitors have been recommended for the management of heart failure with mildly reduced (HFmrEF) or preserved ejection fraction (HFpEF) (class IIA), according to the 2022 AHA/ACC/HFSA Heart Failure Management Guidelines. These drugs have demonstrated benefits in reducing the rehospitalization rate and CV mortality in HFmrEF and HFpEF patients (Heidenreich et al., 2022). Additionally, animal studies have highlighted the potential of SGLT2 inhibitors in mitigating atherosclerosis progression (Ganbaatar et al., 2020; Al-Sharea et al., 2018; Nasiri-Ansari et al., 2018; Nakatsu et al., 2017).

The 2024 ESC Guidelines for the management of atrial fibrillation recommend effective glycemic control as part of comprehensive risk factor management in individuals with diabetes mellitus and AF. This approach is beneficial for reducing burden, recurrence, and progression of AF (class IC) (Van Gelder et al., 2024). As novel hypoglycemic agents with cardiovascular benefits, SGLT2 inhibitors have been shown to have potential antiarrhythmic effects in limited clinical and animal researches. In a post hoc analysis of DECLARE-TIMI58, Zelniker et al. (2020) observed that dapagliflozin significantly reduced the incidence of atrial fibrillation (AF) and atrial flutter (AFL) in patients with T2DM, irrespective of prior history of AF, atherosclerotic heart disease or HF. Our previous research further demonstrated the anti-arrhythmic potential of empagliflozin, in an ex-vivo myocardial ischemia-reperfusion rabbit model (Azam et al., 2021). Despite several meta-analyses evaluating the effects of SGLT2 inhibitors on AF/AFL, their findings remain inconsistent (Li et al., 2021; Pandey et al., 2021; Zhang et al., 2024). The association between SGLT2 inhibitors and the other arrythmias remains even less explored. To address this gap, we performed a systematic review and meta-analysis of randomized controlled clinical trials (RCTs) evaluating the impact of SGLT2 inhibitors on various arrhythmias, including AF/AFL, ventricular tachycardia (VT), ventricular fibrillation (VF), and sinus bradycardia, with the ultimate goal of informing evidence-based clinical decision-making.

2 Methods

This research strictly adhered to the Guidelines for Systematic Review and Meta-Analysis (PRISMA) statement (Page et al., 2021) across all stage, including data sources, search strategies, data acquisition, inclusion and exclusion criteria, outcome measures, quality assessment, and statistical methods. The protocol for this systematic review and meta-analysis was registered with the International Prospective Register of Systematic Reviews (PROSPERO: CRD42022371089).

2.1 Inclusion and exclusion criteria

The inclusion and exclusion criteria were developed based on PICOTS (Table 1).

Table 1
www.frontiersin.org

Table 1. Inclusion criteria and exclusion criteria.

The inclusion criteria included: (1) Adult participants (≥18 years old); (2) Intervention group treated with SGLT2 inhibitors (dapagliflozin, empagliflozin, canagliflozin, ertugliflozin, tofogliflozin, luseogliflozin, ipragliflozin, remogliflozin and sergliflozin) or SGLT1/2 inhibitors (sotagliflozin and licogliflozin), and control group (placebo); (3) Follow-up duration≥52 weeks; (4) Report of arrhythmia events (AF, AFL, VT, VF. and sinus bradycardia); (5) RCTs.

Exclusion criteria encompassed non-randomized placebo-controlled trials, animal studies, reviews, meta-analyses, case reports, letters, guidelines, expert consensuses, and non-English literatures.

2.2 Search strategy and data sources

We systematically searched of PubMed, Embase, Web of Science, and ClinicalTrials.gov for relevant studies published from each database’s inception up to 30 June 2024. The search term in ClinicalTrials.gov was “Sodium-Glucose Transporter 2 Inhibitors” with the filters set as “with results,” “intervention studies,” “adults (18–64),” and “older adults (65+).” The search terms in PubMed, Embase, Web of Science included “sodium glucose cotransporter 2 inhibitor,” “dapagliflozin,” “empagliflozin,” “canagliflozin,” “tofogliflozin,” “luseogliflozin,” “ertugliflozin,” “sergliflozin,” “ipragliflozin,” “remogliflozin,” “sotagliflozin,” “licogliflozin,” “atrial fibrillation,” “atrial flutter,” “tachycardia, ventricular,” “ventricular fibrillation,” “sinus bradycardia” and other relevant terms. Specific search strategies were detailed in the Supplementary Table S1.

2.3 Study selection, data extraction and quality assessment

All the studies were independently identified, reviewed, and screened by two reviewers (Z.X. Yu and H.Y. Yan) based on titles, abstracts and full texts. Disagreements were resolved through discussion or third-party consultation (W.W. Chen).

Using a unified data extraction form, two reviewers (R. Chen and H.M. Zhang) independently abstracted data on intervention and outcome, and recorded study and participant characteristics. Disagreements were resolved through discussion or third-party consultation (P.P. Li).

The risk of bias was assessed using the domains suggested in the Cochrane Handbook for Systematic Review of Interventions, Version 5.1.0, (Higgins JPT, Green S, eds. Cochrane Handbook for Systematic Reviews of Interventions [version 5.1.0. updated March 2011] http://handbook.Cochrane.org/. Accessed 6 August 2024), including selection bias (random sequence generation, allocation concealment), performance bias (blinding of participants and personnel), detection bias (blinding of outcome assessment), attrition bias (incomplete outcome data), reporting bias (selective reporting) and other bias.

2.4 Data analysis

The primary outcome was the incidence of AF/AFL, while the secondary outcomes comprised VT, VF, and sinus bradycardia.

The pooled risk ratios (RRs) with 95% confidence intervals (CIs) were used to estimate incidence of arrhythmias, with P-values <0.05 considered statistical significance. Heterogeneity was assessed using Q tests and I2 statistics. The Mantel–Haenszel test with fixed-effects model was applied when P-value for Q test>0.1 and I2<50%, while random-effects model was used otherwise. Funnel plots were used to evaluate the publication bias of included studies. All analyses followed the intention-to-treat principle and were conducted using RevMan 5.4.1 (The Cochrane Collaboration). The sensitivity analysis was conducted using the leave-one-out method to evaluate the reliability of the results.

3.3 Meta-analysis

3.3.1 The effect of SGLT2 inhibitors on AF/AFL

All 39 included RCTs reported on AF/AFL events. The meta-analysis revealed that patients treated with SGLT2 inhibitors had a reduced risk of AF/AFL compared with placebo (RR 0.86; 95%CI, 0.77–0.95; I2 = 0%; P = 0.003) (Figure 3). In 19 RCTS, SGLT2 inhibitors were grouped by dosage (dapagliflozin 10 mg/5 mg, empagliflozin 25 mg/10 mg, canagliflozin 300 mg/100 mg, ertugliflozin 15 mg/5 mg, sotagliflozin 400 mg/200 mg). Meta-analysis of high-dose versus low-dose SGLT2 inhibitors showed no statistically significant difference in the risk of AF/AFL (RR 0.78; 95%CI, 0.60–1.02; I2 = 0%; P = 0.07), although a decreasing trend was observed in the high-dose group (Figure 4). Of all trials, 31 enrolled patients with DM (30 with Type2 DM, 1 with Type 1 DM), 5 with HF (2 with HFrEF, 2 with HFpEF and 1 with HF of unspecified classification), and 8 with CKD (8 with both DM and CKD and 1 with CKD only). The RCTs included in this study involved different participant populations, with 31 focusing on DM, 5 on HF, and 8 on CKD. We conducted separate meta-analyses for each population subgroup. The result revealed that SGLT2 inhibitors significantly reduced AF/AFL risk compared to placebo in both DM (RR 0.84; 95%CI, 0.73–0.96; I2 = 0%; P = 0.01) and CKD patients (RR 0.72; 95%CI, 0.55–0.94; I2 = 0%; P = 0.02), but showed no significant effect in HF patients (RR 0.90; 95%CI, 0.64–1.27; I2 = 69%; P = 0.56) (Supplementary Figures S1–S3).

3.3.2 The effect of SGLT2 inhibitors on VT, VF, sinus bradycardia

16 RCTs reported on VT events. The meta-analysis showed there was no significant difference in the risk of VT between the SGLT2 inhibitors group and the placebo group (RR 0.99; 95%CI, 0.81–1.22; I2 = 0%; P = 0.96) (Figure 5). Similarly, 14 RCTs reported on VF events, with no significant difference observed (RR 1.06; 95%CI, 0.73–1.54; I2 = 0%; P = 0.75) (Figure 6). 8 RCTs reported on sinus bradycardia events, and again, no significant difference was identified (RR 1.12; 95%CI, 0.57–2.18; I2 = 0%; P = 0.74) (Figure 7).

3.4 Sensitivity analysis and publication bias

Sensitivity analysis was conducted using the leave-one-out method. We found that the results of meta-analysis of AF/AFL, VT, VF, and sinus bradycardia were robust and not influenced by any single study. However, in the model evaluating the effect of different doses of SGLT2 inhibitors on AF/AFL, a statistically significant result was observed after excluding NCT01986881 (RR 0.68; 95%CI, 0.48–0.96; I2 = 0%; P = 0.03).

The funnel plots were symmetrical, suggested that the probability of publication bias is low (Figure 8).

4 Discussion

Atrial fibrillation, the most common arrhythmia worldwide with an increasing incidence (Joglar et al., 2024), is strongly associated with diabetes mellitus. The diabetic state facilitates the maintenance of AF by inducing atrial structural and electrical remodeling (Karam et al., 2017). SGLT2 inhibitors, a novel class of hypoglycemic agents, present a potential avenue for mitigating AF/AFL. A post hoc analysis derived from the large randomized controlled clinical trial DECLARE-TIMI58 reported that dapagliflozin reduced AF/AFL adverse events in patients with type 2 diabetes irrespective of a history of AF/AFL, atherosclerotic cardiovascular disease or HF (Zelniker et al., 2020). Metabolic remodeling is a catalyst for the initiation and perpetuation of AF (Bode et al., 2024). 2024 ESC Guidelines for the management of atrial fibrillation recommend effective glycemic control is beneficial for reducing burden, recurrence, and progression of AF in individuals with diabetes mellitus and AF (class IC) (Van Gelder et al., 2024). However, the evidence supporting this recommendation remains relatively limited.

Our meta-analysis of 39 RCTs demonstrated that patients treated with SGLT2 inhibitors had a significantly lower risk of AF/AFL compared with those receiving placebo (RR 0.86; 95%CI, 0.77–0.95; P = 0.003). This finding aligns with some previous meta-analyses (Li et al., 2021; Pandey et al., 2021). Differently, to assess the long-term effect of SGLT2 inhibitors on the risk of AF/AFL more comprehensively and accurately, we included only RCTs with a follow-up duration of at least 52 weeks, along with some unpublished raw data from ClinicalTrials.gov (NCT03066830, NCT02926950, NCT03285594, NCT03332771, and NCT04065841), and incorporated the most recent publications. Furthermore, our study directly compared the effects of high-dose and low-dose SGLT2 inhibitors on AF/AFL risk. While a decreasing trend was noted in the high-dose group, the difference was not statistically significant. Interestingly, sensitivity analysis revealed that the high-dose group had a statistically significant reduction in AF/AFL risk after excluding NCT01986881 (RR 0.68; 95%CI, 0.48–0.96; P = 0.03). This sensitivity analysis result should be interpreted cautiously, as excluding a high-quality trial may introduce bias. An animal study showed that high-dose empagliflozin significantly reduced AF inducibility in diabetic rats, compared with low-dose empagliflozin (Shao et al., 2019), contrasting our findings. Notably, there was also a study that reported findings different from the conclusions of our research. Zhang et al. (2024) reported in a meta-analysis that SGLT2 inhibitors did not reduce the risk of AF occurrence, irrespective of follow-up duration, drug type or dose, or the patient population. While their meta-analysis included trials published up to July 2023, our study incorporated additional evidence from newly published trials in 2023–2024 as well as five unpublished trials. These expanded data sources might contribute to the observed differences in outcomes. So more relevant clinical trials are necessary to clarify whether dosing influences the efficacy of SGLT2 inhibitors against AF/AFL in the future. In addition to AF/AFL, our research explored the effects of SGLT2 inhibitors on other arrhythmias. Unfortunately, SGLT2 inhibitors had no significant improvement in the risks of VT, VF, and sinus bradycardia (P > 0.05).

The mechanisms underlying the beneficial effects of SGLT2 inhibitors on AF are still under investigation. Shao et al. (2019) demonstrated that empagliflozin could inhibit oxidative stress, improve mitochondrial function, alleviate left atrial fibrosis, and reduce the incidence of AF in diabetic rats. Notably, the high-dose empagliflozin group showed a more significant reduction in left atrial fibrosis and AF incidence compared to the low-dose group. In our previous study, we found that empagliflozin improved calcium dysregulation caused by myocardial ischemia-reperfusion (Azam et al., 2021), a factor known to play a crucial role in the electrophysiological mechanisms underlying AF. Endoplasmic reticulum (ER) stress-mediated apoptosis was a contributing factor to the development of AF (Shi et al., 2015). Dapagliflozin has been shown to significantly suppress ER stress and cardiac fibrosis, reduce the incidence of AF and shorten the duration of AF in mitral regurgitation rats (Lin et al., 2021). Epicardial adipose tissue (EAT), a unique fat reservoir located between the myocardium and the epicardial visceral layer, is both a risk factor and an independent predictor for the occurrence and recurrence of AF after ablation. Mechanisms contributing to the occurrence of AF include genetic and neurological factors, inflammation, oxidative stress, fibrosis, fat infiltration, and atrial electrical or structural remodeling (Iacobellis, 2022; Wong et al., 2017). Empagliflozin has been shown to alleviate EAT inflammation by reducing GAPDH malonylation through downregulation of ACC1 expression, thereby attenuating atrial fibrosis (Li et al., 2023). Similarly, Badreldin et al. (2024) found that empagliflozin could protect the heart from AF in rats by inhibiting the NF-κB/HIF-1α regulatory axis and atrial remodeling. These animal studies provide further support for our conclusion that SGLT2 inhibitors have a beneficial impact on AF.

SGLT2 inhibitors, as part of guideline-directed medical therapy for patients with HFrEF, are now widely used in clinical practice, particularly dapagliflozin and empagliflozin. Data from the OpTIMa-HF registry, an observational, multicenter, real-world study of Italian HFrEF patients, demonstrate their rapid adoption: 63.2% of patients were prescribed SGLT2 inhibitors, with dapagliflozin (76%) and empagliflozin (23.6%) being the most common, while canagliflozin and ertugliflozin accounted for only 0.4%. These findings underscore the swift integration of SGLT2 inhibitors into routine HFrEF management (Paolillo et al., 2025). Some animal studies have shown their beneficial effects on atrial electrophysiology in heart failure models. Bode et al. (2021) found that sotagliflozin ameliorated left atrial (LA) remodeling in metabolic HFpEF. It also improved key features of Ca2+-mediated cellular arrhythmogenesis in LA cardiomyocytes, such as the magnitude of spontaneous Ca2+ release events (SCaEs), mitochondrial Ca2+ buffering capacity, diastolic calcium accumulation, and sodium-calcium exchanger (NCX) activity. Trum et al. (2024) isolated cardiomyocytes from atrial biopsies of HFpEF or non-HF patients undergoing elective cardiac surgery. They found increased Na influx in human atrial cardiomyocytes from HFpEF patients, partly due to an increase late sodium current (late INa), and this increase was associated with AF susceptibility (Zhang et al., 2017). Notably, empagliflozin significantly reduced both Na + influx and late INa (Trum et al., 2024), suggesting a potential therapeutic benefit for AF in HFpEF. Despite these promising mechanistic insights, our meta-analysis failed to demonstrate significant AF/AFL risk reduction in HF patients, possibly due to the limited number of RCTs focusing specifically on HF cohorts and substantial heterogeneity observed among these trials (I2>50%). Therefore, further well-designed RCTs in HF subgroups are needed to validate these results and assess whether SGLT2 inhibitors reduce AF/AFL risk in this population.

This meta-analysis has some limitations that warrant consideration. Firstly, in the vast majority of the included RCTs, arrhythmia events were reported as adverse events rather than primary or secondary outcomes. Secondly, some RCTs lacked detailed reporting on the arrhythmia history of participants, such as paroxysmal AF/AFL and persistent AF/AFL, which might complicate the accurate evaluation of SGLT2 inhibitors’ effects.

In summary, our meta-analysis demonstrates that SGLT2 inhibitors significantly reduce the risk of AF/AFL but have no notable impact on the risk of VT, VF, and sinus bradycardia. Furthermore, our study found no statistically significant dose-dependent differences in AF/AFL incidence. In the future, large-scale randomized controlled clinical trials focusing on SGLT2 inhibitors and arrhythmias are needed to validate our findings.
