    • Despite major therapeutic advances over the last decades, complex supraventricular and ventricular arrhythmias (VAs), particularly in the emergency setting or during revascularization for acute myocardial infarction (AMI), remain an important clinical problem. Although the incidence of VAs has declined in the hospital phase of acute coronary syndromes (ACS), mainly due to prompt revascularization and optimal medical therapy, still up to 6% patients with ACS develop ventricular tachycardia and/or ventricular fibrillation within the first hours of ACS symptoms. Despite sustained VAs being perceived predictors of worse in-hospital outcomes, specific associations between the type of VAs, arrhythmia timing, applied treatment strategies and long-term prognosis in AMI are vague. Atrial fibrillation (AF) is the most common supraventricular tachyarrhythmia that may be asymptomatic and/or may be associated with rapid haemodynamic deterioration requiring immediate treatment. It is estimated that over 20% AMI patients may have a history of AF, whereas the new-onset arrhythmia may occur in 5% patients with ST elevation myocardial infarction. Importantly, patients who were treated with primary percutaneous coronary intervention for AMI and developed AF have higher rates of adverse events and mortality compared with subjects free of arrhythmia. The scope of this position document is to cover the clinical implications and pharmacological/non-pharmacological management of arrhythmias in emergency presentations and during revascularization. Current evidence for clinical relevance of specific types of VAs complicating AMI in relation to arrhythmia timing has been discussed.

  • Atrial fibrillation history impact on catheter ablation outcome : Findings from the ESC-EHRA atrial fibrillation ablation long-term registry
  • 2019
  • Ingår i: Pacing and Clinical Electrophysiology. - : Wiley. - 0147-8389 .- 1540-8159. ; 42:3, s. 313-320

    • BACKGROUND: Atrial fibrillation (AF) promotes atrial remodeling that in turn promote AF perpetuation. The aim of our study was to investigate the impact of AF history length on one-year outcome of AF catheter ablation in a cohort of patients enrolled in the Atrial Fibrillation Ablation Registry.METHODS: We described the real-life clinical epidemiology, therapeutic strategies and the short- and mid-term outcomes of 1948 patients (71.9% with paroxysmal AF) undergoing AF ablation procedures, stratified according to AF history duration (< 2 years or ≥ 2 years).RESULTS: The mean AF history duration was 46,2±57,4 months, 592 patients had an AF history duration < 2 years (mean 10,2±5,9 months), and 1356 patients ≥ 2 years (mean 75,5±63,5 months) (P < 0.001). Patients with AF history duration < 2 years were younger, had a lower incidence of hypertension, coronary artery disease, hypertrophic cardiomyopathy and had a lower CHA2 DS2 -VaSc Score. At one year, the logrank test showed a lower incidence of AF recurrence in patients with AF history duration < 2 years (28.9%) than in patients with AF history duration ≥ 2 years (34.0%) (P = 0.037). AF history duration ≥ 2 years, overall ablation procedure duration, hypertension and chronic kidney disease were all predictors of recurrences after the blanking period.CONCLUSIONS: In this multicenter registry, performing catheter ablation in patients with an AF history ≥ 2 years was associated with higher rates of AF recurrences at one year. Since cumulative time in AF in not necessarily equivalent to AF history, its role remains to be clarified.

  • Antibiotic-Eluting Envelopes for the Prevention of Cardiac Implantable Electronic Device Infections : Rationale, Efficacy, and Cost-Effectiveness
  • 2022
  • Ingår i: Frontiers in Cardiovascular Medicine. - : Frontiers Media S.A.. - 2297-055X. ; 9
  • Forskningsöversikt (refereegranskat)abstract
    • Infections related to cardiac implantable electronic devices (CIED) are associated with significant morbidity and mortality. Despite optimal use of antimicrobials and other preventive strategies, the incidence of CIED infections is increasing over time leading to considerable costs to the healthcare systems. Recently, antibiotic-eluting envelopes (AEEs) have been introduced as a promising technology to prevent CIED infections. This review will address the current evidence on stratification of CIED infection risk, present the rationale behind AEE, and summarize the currently available evidence for CIED infection prevention as well as demonstrate the cost-effectiveness of this novel technology.

  • Clinical practice and implementation of guidelines for the prevention, diagnosis and management of cardiac implantable electronic device infections : results of a worldwide survey under the auspices of the European Heart Rhythm Association
  • 2019
  • Ingår i: Europace. - : Oxford University Press. - 1099-5129 .- 1532-2092. ; 21:8, s. 1270-1279

    • AIMS: Cardiac implantable electronic device (CIED) infection rates are increasing. Worldwide compliance and disparities to published guidelines for the prevention, diagnosis and management of these conditions are not well elucidated. The purpose of this survey, therefore, was to clarify these issues through an inquiry to arrhythmia-related associations and societies worldwide.METHODS AND RESULTS: A questionnaire comprising 15 questions related to CIED infections was distributed among members of seven arrhythmia societies worldwide. A total of 234 centres in 62 countries reported implantation rates of which 159 (68.0%) performed more than 200 device implantations per year and 14 (6.0%) performed fewer than 50 implantations per year. The reported rates of CIED infections for 2017 were ≤2% in 78.7% of the centres, while the infection rates exceeded 5% in 7.8% of the centres. Preventive measures for CIED infection differed from published recommendations and varied among different regions mainly in terms of pocket irrigation and administering post-operative antimicrobial therapy the use of which was reported by 39.9% and 44% of the respondents, respectively. Antibacterial envelopes were used by 37.7% of the respondents in selected circumstances. In terms of pocket infection management, 62% of the respondents applied complete system removal as an initial step. Diagnostic pocket needle aspiration and pocket surgical debridement were reported by 15.8% and 11.8% of centres, respectively.CONCLUSION: Clinical practices for prevention and management of CIED do not fully comply with current recommendations and demonstrate considerable regional disparities. Further education and programmes for improved implementation of guidelines are mandatory.

  • Influence of risk factors in the ESC-EHRA EORP atrial fibrillation ablation long-term registry
  • 2019
  • Ingår i: Pacing and Clinical Electrophysiology. - : Wiley. - 0147-8389 .- 1540-8159. ; 42:10, s. 1365-1373
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The influence of risk factors on atrial fibrillation (AF) ablation recurrence is increasingly recognized. We present a sub-analysis of the European Society of Cardiology-European Heart Rhythm Association-European Society of Cardiology AF ablation long-term registry on the effect of traditional risk factors for AF on postablation recurrence, reablation, and complications using real-world data.Methods: Risk factors for AF were defined as body mass index >= 27 kg/m(2), hypertension, chronic obstructive pulmonary disease, diabetes, alcohol >= 2 units/day, sleep apnea, smoking, no/occasional sports activity, moderate/severe mitral or aortic valve disease, any cardiomyopathy, peripheral vascular disease, chronic kidney disease, heart failure, coronary artery disease/infarction, and previous pacemaker/defibrillator implant. Patients were divided in two groups with >= 1 or without risk factors. Primary outcomes were arrhythmia recurrence after blanking period, reablation, and adverse events or death. Differences between the groups and the influence of individual risk factors were analyzed using multivariate Cox regression.Results: Three thousand sixty nine patients were included; 217 patients were without risk factors. Risk factor patients were older (58.4 vs 54.1 years), more often female (32% vs 19.8%) and had more often persistent AF (27.2% vs 23.5%). In a multivariate analysis, patients without risk factors had a hazard ratio of 0.70 (95% CI 0.49-0.99) for recurrence compared to risk factor patients. The multivariate hazard ratios for reablation or adverse events/death were not different between the two groups. Hypertension and body mass index were univariate predictors of recurrence.Conclusions: Patients with >= 1 risk factor had a 30% higher risk for arrhythmia recurrence after ablation, but no differences in risk for repeat ablations and adverse events or death.
