AIMS
Standardized data definitions are essential for monitoring and assessment of care and outcomes in observational studies and randomized controlled trials (RCTs). The European Unified Registries for Heart Care Evaluation and Randomized Trials (EuroHeart) project of the European Society of Cardiology aimed to develop contemporary data standards for atrial fibrillation/flutter (AF/AFL) and catheter ablation.
METHODS AND RESULTS
We used the EuroHeart methodology for the development of data standards and formed a Working Group comprising 23 experts in AF/AFL and catheter ablation registries, as well as representatives from the European Heart Rhythm Association and EuroHeart. We conducted a systematic literature review of AF/AFL and catheter ablation registries and data standard documents to generate candidate variables. We used a modified Delphi method to reach a consensus on a final variable set. For each variable, the Working Group developed permissible values and definitions, and agreed as to whether the variable was mandatory (Level 1) or additional (Level 2). In total, 70 Level 1 and 92 Level 2 variables were selected and reviewed by a wider Reference Group of 42 experts from 24 countries. The Level 1 variables were implemented into the EuroHeart IT platform as the basis for continuous registration of individual patient data.
CONCLUSION
By means of a structured process and working with international stakeholders, harmonized data standards for AF/AFL and catheter ablation for AF/AFL were developed. In the context of the EuroHeart project, this will facilitate country-level quality of care improvement, international observational research, registry-based RCTs, and post-marketing surveillance of devices and pharmacotherapies.

Review
Angiotensin receptor-neprilysin inhibitor (ARNI) use has become increasingly popular. Current guidelines recommend using ARNI therapy for heart failure with reduced (HFrEF) and preserved ejection fraction (HFpEF). As therapies become more widely available, heart failure-associated burdens such as ventricular arrhythmias and sudden cardiac death (SCD) will become increasingly prevalent. We conducted a systematic review and meta-analysis to assess the impact of ARNI therapy on HFrEF and HFpEF pertaining to arrhythmogenesis and SCD. We performed a search of MEDLINE (PubMed), the Cochrane Library, and ClinicalTrials.gov for relevant studies. The odds ratios (ORs) of SCD, ventricular tachycardia (VT), ventricular fibrillation (VF), atrial fibrillation/flutter (AF), supraventricular tachycardia (SVT), and implantable cardioverter-defibrillator (ICD) shocks were calculated. A total of 10 studies, including 6 randomized controlled trials and 4 observational studies, were included in the analysis. A total of 18,548 patients from all studies were included, with 9,328 patients in the ARNI arm and 9,220 patients in the angiotensin-converting enzyme inhibitor (ACEI)/angiotensin II receptor blocker (ARB) arm, with a median follow-up time of 15 months. There was a significant reduction in the composite outcomes of SCD and ventricular arrhythmias in patients treated with ARNIs compared to those treated with ACEIs/ARBs (OR, 0.71; 95% confidence interval, 0.54-0.93; = .01; I = 17%; = .29). ARNI therapy was also associated with a significant reduction in ICD shocks. There was no significant reduction in the VT, VF, AF, or SVT incidence rate in the ARNI group compared to the ACEI/ARB group. In conclusion, the use of ARNIs confers a reduction in composite outcomes of SCD and ventricular arrhythmias among patients with heart failure. These outcomes were mainly driven by SCD reduction in patients treated with ARNIs.

Meta-Analysis Review
BACKGROUND
Postoperative atrial fibrillation/flutter (POAF) is one of the most common cardiac complications after lung surgery. We aimed to assess the safety and efficacy of pharmacological interventions for new-onset POAF prophylaxis in patients with lung cancer after lung surgery.
METHODS
PubMed, Embase, Web of Science, Scopus, and the Cochrane Library were searched to identify randomized controlled trials comparing the effects of pharmacological interventions to prevent POAF following lung surgery.
RESULTS
A total number of 19 studies with 2,922 participants were included. Pharmacological interventions significantly reduced the incidence of POAF (odds ratio [OR] 0.36, 95% confidence interval [95% CI] 0.26-0.52) while did not increase the incidence of severe pulmonary complications (OR 1.17, 95% CI 0.57-2.41) after lung surgery compared with placebo/usual care. Among different trials, beta-blockers appeared to be the most effective with an OR of 0.13 (95% CI, 0.07-0.27) and a number needed-to-treat (NNT) of 3.63 and was considered safe with no serious adverse events recorded. The risk of POAF decreased from 25.6 to 11.4% (P < 0.001) overall and from 34.2 to 6.7% (P < 0.001) with beta-blockers as monotherapy. Pharmacological interventions did not reduce the 30-day mortality (OR 0.89, 95% CI 0.43-1.84, I = 0%), but showed a trend toward reducing major cardiovascular complications including myocardial ischemia/infarction, cardiac arrest, heart failure, and stroke (OR 0.41, 95% CI 0.13-1.29, I = 0%).
CONCLUSION
Current clinical evidence supports the effectiveness of pharmacological intervention with beta-blockers, amiodarone, magnesium sulfate, or calcium-channel blockers to reduce the incidence of POAF after lung surgery in patients with lung cancer. In the absence of contraindications, prophylaxis with beta-blockers seems to be the most effective of the treatments studied.

Meta-Analysis
PURPOSE
An update of a systematic review and meta-analysis of the risk of arrhythmias and their subtypes in type 2 diabetic patients receiving glucagon-like peptide 1 receptor agonist (GLP-1RA) medication according to data from the Cardiovascular Outcome Trial(CVOT).
METHODS
Randomized controlled trials (RCT) on GLP-1RA therapy and cardiovascular outcomes in type 2 diabetes mellitus patients published in full-text journal databases such as MEDLINE (via PubMed), Embase, Clinical Trials.gov, and the Cochrane Library from establishment to March 1, 2022 were searched. We assessed the quality of individual studies by the Cochrane risk-of-bias algorithm. RevMan 5.4.1 software was use for calculating meta-analysis.
RESULTS
A total of 60,081 randomized participants were included in the data of these 8 GLP-1RA cardiovascular outcomes trials. Pooled analysis reported no significant effect on total arrhythmia [RR=0.96, 95% CI (0.96, 1.05), =0.36], and its subtypes such as atrial fibrillation [RR=0.96, 95% CI (0.86, 1.07), =0.43], atrial flutter [RR= 0.82, 95% CI (0.57, 1.19), =0.30], atrial tachycardia [RR=0.64, 95% CI (0.20, 2.01), =0.44)], sinoatrial node dysfunction [RR=0.74, 95% CI (0.44, 1.25), =0.26], ventricular preterm systole [RR=1.42, 95% CI (0.62, 3.26), =0.41], second degree AV block [RR=0.96, 95% CI (0.53, 1.72), =0.88], complete AV block [RR=0.75, 95% CI (0.49, 1.17), =0.21], ventricular fibrillation [RR=1.00, 95% CI (0.50, 2.02), =1.00], ventricular tachycardia [RR=1.37, 95% CI (0.91, 2.08), =0.13] from treatment with GLP-1RA versus placebo. However, the risk of hypoglycemia was reduced by about 30% [RR=0.70, 95% CI (0.57, 0.87), =0.001] and the risk of pneumonia by about 25% [RR=0.85, 95% CI (0.75, 0.97), =0.01], both statistically significant differences.
CONCLUSION
In type 2 diabetic patients, treatment with GLP-1RA has no significant effect on the risk of major arrhythmias but significantly reduces the risk of hypoglycemia and pneumonia.

Review
The advantage of prophylactic cavotricuspid isthmus (CTI) ablation for AF patients without documented atrial flutter is still unclear. The present study aimed to evaluate the role of prophylactic CTI ablation in this population. A systematic review and meta-analysis study was conducted. The overall effects estimation was conducted using random effects models. The pooled effects were presented as the risk difference and standardised mean difference for dichotomous and continuous outcomes, respectively. A total of 1,476 patients from four studies were included. The risk of atrial tachyarrhythmias following a successful catheter ablation procedure was greater in the pulmonary vein isolation + CTI ablation group than pulmonary vein isolation alone group (34.8% versus 28.2%; risk difference 0.08; 95% CI [0.00-0.17]; p=0.04). Prophylactic CTI ablation was associated with a higher recurrent AF rate (33.8% versus 27.1%; risk difference 0.07; 95% CI [0.01-0.13]; p=0.02). Additional prophylactic CTI ablation to pulmonary vein isolation significantly increased the radio frequency application time (standardised mean difference 0.52; 95% CI [0.04-1.01]; p=0.03). This study suggested that prophylactic CTI ablation was an ineffective and inefficient approach in AF without documented typical atrial flutter patients.

Fetal arrhythmias are common cardiac abnormalities associated with high mortality due to ventricular dysfunction and heart failure, particularly when accompanied by hydrops. Although several types of common fetal tachycardias have been relatively identified medications, such as digoxin, flecainide, and sotalol, there is no first-line drug treatment protocol established for the treatment of various types of fetal tachycardias. We conducted a network meta-analysis using a Bayesian hierarchical framework to obtain a model for integrating both direct and indirect evidence. All tachycardia types (Total group), supraventricular tachycardia (SVT subgroup), atrial flutter (AF subgroup), hydrops subgroup, and non-hydrops subgroup fetuses were analyzed, and five first-line regimens were ranked according to treatment outcomes: digoxin monotherapy (D), flecainide monotherapy (F), sotalol monotherapy (S), digoxin plus flecainide combination therapy (DF), and digoxin plus sotalol combination therapy (DS). Effectiveness and safety were determined according to the cardioversion rate and intrauterine death rate. The pooled data indicated that DF combination therapy was always superior to D monotherapy, regardless of the tachycardia type or the presence of hydrops: Total, 2.44 (95% CrI: 1.59, 3.52); SVT, 2.77 (95% CrI: 1.59, 4.07); AF, 67.85 (95% CrI: 14.25, 168.68); hydrops, 6.03 (95% CrI: 2.54, 10.68); and non-hydrops, 5.06 (95% CrI: 1.87, 9.88). DF and F had a similar effect on control of fetal tachycardias. No significant differences were observed when comparing S, DS with D therapies across the subgroup analyses for the SVT, hydrops, and non-hydrops groups. No significant differences in mortality risks were among the various treatment regimens for the total group. And no significant differences were found in rates of intrauterine death rates at the same cardioversion amount. The flecainide monotherapy and combination of digoxin and flecainide should be considered the most superior therapeutic strategies for fetal tachycardia.

The effectiveness of SGLT2 inhibitor in the incidence of atrial fibrillation/atrial flutter in patients with type 2 diabetes mellitus/heart failure: a systematic review and meta-analysis.
BACKGROUND
Type 2 diabetes mellitus (T2D) and heart failure (HF) are closely related to the increased risk of atrial fibrillation (AF)/atrial flutter (AFL). However, massive clinical studies have shown that sodium glucose cotransporter 2 inhibitor (SGLT2i) affects the occurrence of AF/AFL and its complications, but the promoting or inhibitory effect of SGLT2i on AF/AFL and its complications and the exact probability is not clear, meta-analysis can combine the existing research data to easily solve the clinical problems.
METHODS
We performed a search in the registers of ClinicalTrials.gov from it,s inception to March 2021 to evaluate the occurrence of AF/AFL adverse events in SGLT2i in patients with T2D/HF. Almost all of the included studies were double-blind parallel allocation randomized controlled studies, and only one was open. The control groups all included placebo, some of which also included glimepiride, metformin, liraglutide, etc. Quality risk assessment of the included randomized controlled trials (RCTs) was conducted using Cochrane RoB 2.0., and the publication bias assessment was conducted using STATA 17.0. The odds ratio (OR) combined effect of 95% confidence interval (CI) was used for bivariate variables.
RESULTS
We included data from 22 confirmed trials that included 52,951 T2D/HF patients. The studies had no risk of bias. Analysis of the cumulative results showed that compared with placebo, SGLT2i can significantly reduce the incidence of AF/AFL by 18% (OR =0.82, 95% CI: 0.73 to 0.93, P=0.002), and reduce the incidence of arrhythmia by 14% (OR =0.86, 95% CI: 0.79 to 0.94, P=0.0006); among them, the incidence of AF/AFL in T2D patients was reduced by 20% (OR =0.80, 95% CI: 0.69 to 0.92, P=0.002); Dapagliflozin reduced the incidence of AF/AFL by 15% (OR =0.85, 95% CI: 0.74 to 0.98, P=0.03); the incidence of intracardiac thrombosis decreased by 69% (OR =0.31, 95% CI: 0.10 to 0.91, P=0.03), while the incidence of AF/AFL in women decreased by 17% (OR =0.83, 95% CI: 0.72 to 0.94, P=0.004).
DISCUSSION
This article provides a new direction for the use of SGLT2i, and hopefully it can provide certain theoretical basis for the broader clinical indications of SGLT2i in the future.

Effect of Sodium-Glucose Co-transporter Protein 2 Inhibitors on Arrhythmia in Heart Failure Patients With or Without Type 2 Diabetes: A Meta-Analysis of Randomized Controlled Trials.
AIM
Arrhythmic events such as atrial fibrillation (AF) are tightly associated with an increased risk of heart failure (HF). Previous studies have shown inconsistent results regarding the association between sodium-glucose co-transporter 2 inhibitors (SGLT2i) and the risk of arrhythmia. The purpose of this study was to investigate the association of SGLT2i treatment with arrhythmia outcomes in clinical trials of patients with HF.
METHODS
We searched Embase, PubMed, Web of Science, Medline, The Cochrane Library, and JAMA databases to identify appropriate randomized controlled trials (RCTs) of SGLT2i interventions. Endpoint outcomes included AF, atrial flutter (AFL), AF/AFL, ventricular fibrillation (VF), ventricular tachycardia (VT), VF/VT, and bradycardia. A random-effects model was used for the meta-analysis of all outcomes. The risk of bias and quality of evidence was assessed by using the Cochrane tool and assessment framework.
RESULTS
Out of 1,725 citations, 9 trials were included in this study, with follow-up from 4 weeks to 52 weeks for 10,344 participants (mean age 68.27 years; 69.62% of participants were men). Compared with placebo, SGLT2i reduced the incidence of AF by 37% [ratio risk (RR) 0.63; 95% confidence interval (CI) 0.45-0.87; < 0.05] and AF/AFL by 34% (RR 0.66; 95% CI 0.49-0.90; < 0.05).
CONCLUSIONS
SGLT2i can reduce the risk of cardiac arrhythmias, particularly the AF. Our study provides strong evidence for recommending the use of SGLT2i in patients with HF.

Meta-Analysis
BACKGROUND
Cardiovascular diseases in people living with HIV (PLWH) are becoming increasingly relevant as HIV/AIDS has become more treatable with the advent of highly efficacious antiretroviral therapy. Previous studies suggested that HIV infection is an independent risk factor for atrial arrhythmia. This study aims to collectively analyze these studies to elucidate the incidence and risk factors of atrial arrhythmia in PLWH.
METHODS
Full-text assessments and data extraction were performed from available literature. Atrial arrhythmia was defined as atrial fibrillation or atrial flutter. Incidence rate, risk, and potential risk factors of atrial arrhythmia in PLWH were catalogued, after which random-effects models were used to estimate pooled summary statistics. PRISMA standardized meta-analysis guidelines were followed.
RESULTS
Analysis of 94,928 PLWH had an averaged incidence rate of 6.4 cases of atrial arrhythmia per 1000 person-years. Risk of atrial arrhythmia was significantly higher in PLWH than in the general population (RR 1.35; 95% CI 1.19-1.53). Sex had no association with the risk of incidental atrial arrhythmia in PLWH (RR 1.47; 95% CI 0.95-2.28). Black race (RR 0.68; 95% CI 0.47-0.97) was associated with decreased risk, whereas lower CD4 counts (RR 1.80; 95% CI 1.18-2.77) and increased viral load (RR 1.57; 95% CI 1.19-2.09) suggested increased risk of atrial arrhythmia in PLWH.
CONCLUSIONS
HIV infection is a risk factor of atrial arrhythmia. Providers should be aware of the increased burden of atrial arrhythmia in PLWH and continue to encourage treatment of HIV infection while managing cardiovascular risk factors and screening for arrhythmias in symptomatic patients.

Review
Cardiolaminopathies are a heterogeneous group of disorders which are due to mutations in the genes encoding for nuclear lamins or their binding proteins. The whole spectrum of cardiac manifestations encompasses atrial arrhythmias, conduction disturbances, progressive systolic dysfunction, and malignant ventricular arrhythmias. Despite the prognostic significance of cardiac involvement in this setting, the current recommendations lack strong evidence. The aim of our work was to systematically review the current data on the main cardiovascular outcomes in cardiolaminopathies. We searched PubMed/Embase for studies focusing on cardiovascular outcomes in mutation carriers (atrial arrhythmias, ventricular arrhythmias, sudden cardiac death, conduction disturbances, thromboembolic events, systolic dysfunction, heart transplantation, and all-cause and cardiovascular mortality). In total, 11 studies were included (1070 patients, mean age between 26-45 years, with follow-up periods ranging from 2.5 years up to 45 ± 12). When available, data on the -mutated population were separately reported (40 patients). The incidence rates (IR) were individually assessed for the outcomes of interest. The IR for atrial fibrillation/atrial flutter/atrial tachycardia ranged between 6.1 and 13.9 events/100 pts-year. The IR of atrial standstill ranged between 0 and 2 events/100 pts-year. The IR for malignant ventricular arrhythmias reached 10.2 events/100 pts-year and 15.6 events/100 pts-year for appropriate implantable cardioverter-defibrillator (ICD) interventions. The IR for advanced conduction disturbances ranged between 3.2 and 7.7 events/100 pts-year. The IR of thromboembolic events reached up to 8.9 events/100 pts-year. Our results strengthen the need for periodic cardiological evaluation focusing on the early recognition of atrial arrhythmias, and possibly for the choice of preventive strategies for thromboembolic events. The frequent need for cardiac pacing due to advanced conduction disturbances should be counterbalanced with the high risk of malignant ventricular arrhythmias that would justify ICD over pacemaker implantation.
