    Global DNA methylation analysis of human atherosclerotic plaques reveals extensive genomic hypomethylation and reactivation at imprinted locus 14q32 involving induction of a miRNA cluster2015In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 36, no 16, 993-U23 p.Article in journal (Refereed)
    Abstract [en]

    Aims Genetics can explain just above 10% of the observed heritability in cardiovascular diseases. Epigenetics is about to provide some further explanations, but the information needed for that is in the accumulation phase. Genome-wide DNA methylation analysis has revealed thousands of genes, which are epigenetically differentially regulated in atherosclerotic plaques. Our results point to an additional level of complexity that needs to be integrated into the aetiology of atherogenesis.We conducted a genome-wide analysis to identify differentially methylated genes in atherosclerotic lesions. Methods DNA methylation at promoters, exons and introns was identified by massive parallel sequencing. Gene expression was analysed by microarrays, qPCR, immunohistochemistry and western blots. Results Globally, hypomethylation of chromosomal DNA predominates in atherosclerotic plaques and two-thirds of genes showing over 2.5-fold differential in DNA methylation are up-regulated in comparison to healthy mammary arteries. The imprinted chromatin locus 14q32 was identified for the first time as an extensively hypomethylated area in atherosclerosis with highly induced expression of miR127, -136, -410, -431, -432, -433 and capillary formation-associated gene RTL1. The top 100 list of hypomethylated promoters exhibited over 1000-fold enrichment for miRNAs, many of which mapped to locus 14q32. Unexpectedly, also gene body hypermethylation was found to correlate with stimulated mRNA expression. Conclusion Significant changes in genomic methylation were identified in atherosclerotic lesions. The most prominent gene cluster activated via hypomethylation was detected at imprinted chromosomal locus 14q32 with several clustered miRNAs that were up-regulated. These results suggest that epigenetic changes are involved in atherogenesis and may offer new potential therapeutic targets for vascular diseases.

    Apixaban vs. warfarin with concomitant aspirin in patients with atrial fibrillation: insights from the ARISTOTLE trial2014In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 35, no 4, 224-232 p.Article in journal (Refereed)
    Abstract [en]

    Aims We assessed the effect of concomitant aspirin use on the efficacy and safety of apixaban compared with warfarin in patients with atrial fibrillation (AF). Methods and results In ARISTOTLE, 18 201 patients were randomized to apixaban 5 mg twice daily or warfarin. Concomitant aspirin use was left to the discretion of the treating physician. In this predefined analysis, simple and marginal structured models were used to adjust for baseline and time-dependent confounders associated with aspirin use. Outcome measures included stroke or systemic embolism, ischaemic stroke, myocardial infarction, mortality, major bleeding, haemorrhagic stroke, major or clinically relevant non-major bleeding, and any bleeding. On Day 1, 4434 (24%) patients were taking aspirin. Irrespective of concomitant aspirin use, apixaban reduced stroke or systemic embolism [with aspirin: apixaban 1.12% vs. warfarin 1.91, hazard ratio (HR) 0.58, 95% confidence interval (CI) 0.39-0.85 vs. without aspirin: apixaban 1.11% vs. warfarin 1.32%, HR 0.84, 95% CI 0.66-1.07; P interaction = 0.10] and caused less major bleeding than warfarin (with aspirin: apixaban 3.10 vs. warfarin 3.92%, HR 0.77, 95% CI 0.60-0.99 vs. without aspirin: apixaban 1.82% vs. warfarin 2.78, HR without aspirin 0.65, 95% CI 0.55-0.78; P interaction = 0.29). Similar results were seen in the subgroups of patients with and without arterial vascular disease. Conclusion Apixaban had similar beneficial effects on stroke or systemic embolism and major bleeding compared with warfarin, irrespective of concomitant aspirin use.

    Similar outcome with an invasive strategy in men and women with non-ST-elevation acute coronary syndromes: From the Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART)2011In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 32, no 24, 3128-3136 p.Article in journal (Refereed)
    Abstract [en]

    Aims

    To assess gender differences in outcome with an early invasive or non-invasive strategy in patients with non-ST-elevation acute coronary syndromes (NSTE ACS).

    Methods and results

    We included 46 455 patients [14 819 women (32%) and 31 636 men (68%)] from the SWEDEHEART register, with NSTE ACS, between 2000 and 2006, and followed them for 1 year. In the non-invasive strategy arm, the relative risk (RR) of death was (women vs. men) 1.02 [95% confidence interval (CI), 0.94-1.11] and in the invasive strategy arm 1.12 (95% CI, 0.96-1.29). After adjustment for baseline differences between the genders, with propensity score and discharge medication, there was a similar trend towards better outcome among women in both the early non-invasive cohort [RR 0.90 (95% CI, 0.82-0.99)] and the early invasive cohort [RR 0.90 (95% CI, 0.76-1.06)], although it did not reach statistical significance in the early invasive cohort. Results were similar with the combined endpoint death/myocardial infarction. An early invasive treatment was associated with a marked, and similar, mortality reduction in women [RR 0.46 (95% CI, 0.38-0.55)] and men [RR 0.45 (95% CI, 0.40-0.52)], without interaction with gender.

    Conclusion

    In this large cohort of patients with NSTE ACS, reflecting real-life management, women and men had similar and better outcome associated with an invasive strategy.

    Outcomes of apixaban vs. warfarin by type and duration of atrial fibrillation: results from the ARISTOTLE trial2013In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 34, no 31, 2464-2471 p.Article in journal (Refereed)
    Abstract [en]

    It is uncertain whether the benefit from apixaban varies by type and duration of atrial fibrillation (AF). A total of 18 201 patients with AF [2786 (15.3) with paroxysmal and 15 412 (84.7) with persistent or permanent] were randomized to apixaban or warfarin. In this pre-specified secondary analysis, we compared outcomes and treatment effect of apixaban vs. warfarin by AF type and duration. The primary efficacy endpoint was a composite of ischaemic or haemorrhagic stroke or systemic embolism. The secondary efficacy endpoint was all-cause mortality. There was a consistent reduction in stroke or systemic embolism (P for interaction 0.71), all-cause mortality (P for interaction 0.75), and major bleeding (P for interaction 0.50) with apixaban compared with warfarin for both AF types. Apixaban was superior to warfarin in all studied endpoints, regardless of AF duration at study entry (P for all interactions 0.13). The rate of stroke or systemic embolism was significantly higher in patients with persistent or permanent AF than patients with paroxysmal AF (1.52 vs. 0.98; P 0.003, adjusted P 0.015). There was also a trend towards higher mortality in patients with persistent or permanent AF (3.90 vs. 2.81; P 0.0002, adjusted P 0.066). The risks of stroke, mortality, and major bleeding were lower with apixaban than warfarin regardless of AF type and duration. Although the risk of stroke or systemic embolism was lower in paroxysmal than persistent or permanent AF, apixaban is an attractive alternative to warfarin in patients with AF and at least one other risk factor for stroke, regardless of the type or duration of AF.

    Risk of arrhythmias in 52 755 long-distance cross-country skiers: a cohort study2013In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 34, no 47, 3624-3631 p.Article in journal (Refereed)
    Abstract [en]

    AIMS:

    We aimed to investigate the association of number of completed races and finishing time with risk of arrhythmias among participants of Vasaloppet, a 90 km cross-country skiing event.

    METHODS AND RESULTS:

    All the participants without cardiovascular disease who completed Vasaloppet during 1989-98 were followed through national registries until December 2005. Primary outcome was hospitalization for any arrhythmia and secondary outcomes were atrial fibrillation/flutter (AF), bradyarrhythmias, other supraventricular tachycardias (SVT), and ventricular tachycardia/ventricular fibrillation/cardiac arrest (VT/VF/CA). Among 52 755 participants, 919 experienced arrhythmia during follow-up. Adjusting for age, education, and occupational status, those who completed the highest number of races during the period had higher risk of any arrhythmias [hazard ratio (HR)1.30; 95% CI 1.08-1.58; for ≥5 vs. 1 completed race], AF (HR 1.29; 95% CI 1.04-1.61), and bradyarrhythmias (HR 2.10; 95% CI 1.28-3.47). Those who had the fastest relative finishing time also had higher risk of any arrhythmias (HR 1.30; 95% CI 1.04-1.62; for 100-160% vs. >240% of winning time), AF (1.20; 95% CI 0.93-1.55), and bradyarrhythmias (HR 1.85; 95% CI 0.97-3.54). SVT or VT/VF/CA was not associated with finishing time or number of completed races.

    CONCLUSIONS:

    Among male participants of a 90 km cross-country skiing event, a faster finishing time and a high number of completed races were associated with higher risk of arrhythmias. This was mainly driven by a higher incidence of AF and bradyarrhythmias. No association with SVT or VT/VF/CA was found.

    Evidence for obesity paradox in patients with acute coronary syndromes: a report from the Swedish Coronary Angiography and Angioplasty Registry2013In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 34, no 5, 345-353 p.Article in journal (Refereed)
    Abstract [en]

    The obesity paradox refers to the epidemiological evidence that obesity compared with normal weight is associated with counter-intuitive improved health in a variety of disease conditions. The aim of this study was to investigate the relationship between body mass index (BMI) and mortality in patients with acute coronary syndromes (ACSs). We extracted data from the Swedish Coronary Angiography and Angioplasty Registry and identified 64 436 patients who underwent coronary angiography due to ACSs. In 54 419 (84.4) patients, a significant coronary stenosis was identified, whereas 10 017 (15.6) patients had no significant stenosis. Patients were divided into nine different BMI categories. The patients with significant stenosis were further subdivided according to treatment received such as medical therapy, percutaneous coronary intervention (PCI), or coronary artery by-pass grafting. Mortality for the different subgroups during a maximum of 3 years was compared using Cox proportional hazards regression with the lean BMI category (21.0 to 23.5 kg/m(2)) as the reference group. Regardless of angiographic findings [significant or no significant coronary artery disease (CAD)] and treatment decision, the underweight group (BMI 18.5 kg/m(2)) had the greatest risk for mortality. Medical therapy and PCI-treated patients with modest overweight (BMI category 26.528 kg/m(2)) had the lowest risk of mortality [hazard ratio (HR) 0.52; 95 CI 0.340.80 and HR 0.64; 95 CI 0.500.81, respectively]. When studying BMI as a continuous variable in patients with significant CAD, the adjusted risk for mortality decreased with increasing BMI up to approximate to 35 kg/m(2) and then increased. In patients with significant CAD undergoing coronary artery by-pass grafting and in patients with no significant CAD, there was no difference in mortality risk in the overweight groups compared with the normal weight group. In this large and unselected group of patients with ACSs, the relation between BMI and mortality was U-shaped, with the nadir among overweight or obese patients and underweight and normal-weight patients having the highest risk. These data strengthen the concept of the obesity paradox substantially.

    Contemporary management of patients undergoing atrial fibrillation ablation: in-hospital and 1-year follow-up findings from the ESC-EHRA atrial fibrillation ablation long-term registry2017In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 38, no 17, 1303-1316 p.Article in journal (Refereed)
    Abstract [en]

    Aims The ESC-EHRA Atrial Fibrillation Ablation Long-Term registry is a prospective, multinational study that aims at providing an accurate picture of contemporary real-world ablation for atrial fibrillation (AFib) and its outcome. Methods and results A total of 104 centres in 27 European countries participated and were asked to enrol 20-50 consecutive patients scheduled for first and re-do AFib ablation. Pre-procedural, procedural and 1-year follow-up data were captured on a web-based electronic case record form. Overall, 3630 patients were included, of which 3593 underwent an AFib ablation (98.9%). Median age was 59 years and 32.4% patients had lone atrial fibrillation. Pulmonary vein isolation was attempted in 98.8% of patients and achieved in 95-97%. AFib-related symptoms were present in 97%. Inhospital complications occurred in 7.8% and one patient died due to an atrioesophageal fistula. One-year follow-up was performed in 3180 (88.6%) at a median of 12.4 months (11.9-13.4) after ablation: 52.8% by clinical visit, 44.2% by telephone contact and 3.0% by contact with the general practitioner. At 12-months, the success rate with or without antiarrhythmic drugs (AADs) was 73.6%. A significant portion (46%) was still on AADs. Late complications included 14 additional deaths (4 cardiac, 4 vascular, 6 other causes) and 333 (10.7%) other complications. Conclusion AFib ablation in clinical practice is mostly performed in symptomatic, relatively young and otherwise healthy patients. Overall success rate is satisfactory, but complication rate remains considerable and a significant portion of patients remain on AADs. Monitoring after ablation shows wide variations. Antithrombotic treatment after ablation shows insufficient guideline-adherence.

    Intra-operative defibrillation testing and clinical shock efficacy in patients with implantable cardioverter-defibrillators: the NORDIC ICD randomized clinical trial2015In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 36, no 37, 2500-2507 p.Article in journal (Refereed)
    Abstract [en]

    Aims This trial was designed to test the hypothesis that shock efficacy during follow-up is not impaired in patients implanted without defibrillation (DF) testing during first implantable cardioverter-defibrillator (ICD) implantation. Methods and results Between February 2011 and July 2013, 1077 patients were randomly assigned (1 : 1) to first time ICD implantation with (n = 540) or without (n = 537) DF testing. The intra-operative DF testing was standardized across all participating centres, and all ICD shocks were programmed to 40 J irrespective of DF test results. The primary end point was the average first shock efficacy (FSE) for all true ventricular tachycardia and fibrillation (VT/VF) episodes during follow-up. The secondary end points included procedural data, serious adverse events, and mortality. During a median follow-up of 22.8 months, the model-based FSE was found to be non-inferior in patients with an ICD implanted without a DF test, with a difference in FSE of 3.0% in favour of the no DF test [confidence interval (CI) -3.0 to 9.0%, Pnon-inferiority <0.001 for the pre-defined non-inferiority margin of 210%). A total of 112 procedure-related serious adverse events occurred within 30 days in 94 patients (17.6%) tested compared with 89 events in 74 patients (13.9%) not tested (P = 0.095). Conclusion Defibrillation efficacy during follow-up is not inferior in patients with a 40 J ICD implanted without DF testing. Defibrillation testing during first time ICD implantation should no longer be recommended for routine left-sided ICD implantation.

    Relationship between baseline haemoglobin and major bleeding complications in acute coronary syndromes2010In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 31, no 1, 50-58 p.Article in journal (Refereed)
    Abstract [en]

    AIMS: In patients with acute coronary syndromes (ACS), the negative impact of baseline haemoglobin levels on ischaemic events, particularly death, is well established, but the association with bleeding risk is less well studied. The aim of this study was to assess the impact of baseline haemoglobin levels on major bleeding complications. METHODS AND RESULTS: Pooled analysis of OASIS 5 and 6 data involving 32 170 patients with ACS with and without ST-segment elevation was performed. The association between baseline haemoglobin and major bleeding or ischaemic events was examined using multiple regression model. MAIN OUTCOME MEASURES: were 30-day rates of major bleeding, death, and death/myocardial infarction (MI) analysed according to baseline haemoglobin levels. Baseline haemoglobin level independently predicted the risk of overall, procedure-related, and non-procedure-related major bleedings at 30 days [odds ratio (OR) 0.94, 95% CI 0.90-0.98; OR 0.94, 95% CI 0.90-0.99; and OR 0.89, 95% CI 0.83-0.95, respectively, per 1 g/dL haemoglobin increment above 10 g/dL]. In addition, a curvilinear relationship between baseline haemoglobin levels and death at 30 days was observed with a 6% decrease in the risk for every 1 g/dL haemoglobin increment above 10 g/dL up to 15.9 g/dL (OR 0.94, 95% CI 0.90-0.98) and a 19% increase above this value (OR 1.19, 95% CI, 0.98-1.43). A similar relationship for the composite outcome of death/MI was observed. CONCLUSION: A low baseline haemoglobin level is an independent predictor of the risk of major bleeding in ACS as well as of the risk of death and death and MI. Among other predictors of bleeding risk, baseline haemoglobin should be taken into account in patients presenting with ACS.

    Bleeding complications with the P2Y12 receptor antagonists clopidogrel and ticagrelor in the PLATelet inhibition and patient Outcomes (PLATO) trial2011In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 32, no 23, 2933-2944 p.Article in journal (Refereed)
    Abstract [en]

    Aims

    More intense platelet-directed therapy for acute coronary syndrome (ACS) may increase bleeding risk. The aim of the current analysis was to determine the rate, clinical impact, and predictors of major and fatal bleeding complications in the PLATO study.

    Methods and results

    PLATO was a randomized, double-blind, active control international, phase 3 clinical trial in patients with acute ST elevation and non-ST-segment elevation ACS. A total of 18 624 patients were randomized to either ticagrelor, a non-thienopyridine, reversibly binding platelet P2Y(12) receptor antagonist, or clopidogrel in addition to aspirin. Patients randomized to ticagrelor and clopidogrel had similar rates of PLATO major bleeding (11.6 vs. 11.2%; P = 0.43), TIMI major bleeding (7.9 vs. 7.7%, P = 0.56) and GUSTO severe bleeding (2.9 vs. 3.1%, P = 0.22). Procedure-related bleeding rates were also similar. Non-CABG major bleeding (4.5 vs. 3.8%, P = 0.02) and non-procedure-related major bleeding (3.1 vs. 2.3%, P = 0.05) were more common in ticagrelor-treated patients, primarily after 30 days on treatment. Fatal bleeding and transfusion rates did not differ between groups. There were no significant interactions for major bleeding or combined minor plus major bleeding between treatment groups and age ≥75 years, weight <60 kg, region, chronic kidney disease, creatinine clearance <60 mL/min, aspirin dose >325 mg on the day of randomization, pre-randomization clopidogrel administration, or clopidogrel loading dose.

    Conclusion

    Ticagrelor compared with clopidogrel was associated with similar total major bleeding but increased non-CABG and non-procedure-related major bleeding, primarily after 30 days on study drug treatment. Fatal bleeding was low and did not differ between groups.

    Admission Troponin T and measurement of ST-segment resolution at 60 min improve early risk stratification in ST-elevation myocardial infarction2004In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 25, no 2, 113-120 p.Article in journal (Refereed)
    Abstract [en]

    AIMS: The prognostic value of admission troponin T (tnT) levels and the resolution of the ST-segment elevation in ST-elevation myocardial infarction (STEMI) is well established. However, the combination of these two early available markers for predicting risk has not been evaluated.

    METHODS AND RESULTS: We evaluated 516 patients with fibrinolytic treated STEMI from the ASSENT-2 and ASSENT-PLUS studies, which had both admission tnT and ST-monitoring available. We used a prospectively defined cut-off value of tnT of 0.1microg/l. For ST-segment resolution, a cut-off of 50% measured after 60min was used. Both a tnT >/=0.1microg/l (n=116) and ST-segment resolution <50% (n=301) were related to higher one-year mortality, 13% vs 4% (P<0.001) and 8.4% vs 2.8% (P=0.009), respectively. In a multivariate analysis ST-segment resolution was and tnT showed a strong trend to be independently related to mortality. The combination of both further improved risk stratification. The one-year mortality in the group with elevation of tnT and without ST-segment resolution compared to the group without tnT elevation and with ST-segment resolution was 18.2% vs 2.8% (P<0.001).

    CONCLUSIONS: Both tnT on admission and ST-segment resolution after 60min are strong predictors of one-year mortality. The combination of both gives additive early information about prognosis and further improves risk stratification.

    Pre-hospital thrombolysis delivered by paramedics is associated with reduced time delay and mortality in ambulance-transported real-life patients with ST-elevation myocardial infarction2006In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 27, no 10, 1146-1152 p.Article in journal (Refereed)
    Abstract [en]

    AIMS: There are sparse data on the impact of pre-hospital thrombolysis (PHT) in real-life patients. We therefore evaluated treatment delays and outcome in a large cohort of ambulance-transported real-life patients with ST-elevation myocardial infarction (STEMI) according to PHT delivered by paramedics or in-hospital thrombolysis. METHODS AND RESULTS: Prospective cohort study used data from the Swedish Register of Cardiac intensive care on patients admitted to the coronary care units of 75 Swedish hospitals in 2001-2004. Ambulance-transported thrombolytic-treated patients younger than age 80 with a diagnosis of acute myocardial infarction were included. Patients with PHT (n=1690) were younger, had a lower prevalence of co-morbid conditions, fewer complications, and a higher ejection fraction (EF) than in-hospital-treated patients (n=3685). Median time from symptom onset to treatment was 113 min for PHT and 165 min for in-hospital thrombolysis. One-year mortality was 7.2 vs. 11.8% for PHT and in-hospital thrombolysis, respectively. In a multivariable analysis, after adjusting for baseline characteristics and rescue angioplasty, PHT was associated with lower 1-year mortality (odds ratio 0.71, 0.55-0.92, P=0.008). CONCLUSION: When compared with regular in-hospital thrombolysis, pre-hospital diagnosis and thrombolysis with trained paramedics in the ambulances are associated with reduced time to thrombolysis by almost 1 h and reduced adjusted 1-year mortality by 30% in real-life STEMI patients.

    Precision of preoperative electrophysiological study in predicting the intraoperatively defined location of single left-sided accessory pathways1987In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 8, no 5, 510-520 p.Article in journal (Refereed)
    Abstract [en]

    In 34 patients with a left-side anomalous pathway (AP) considered for arrhythmia surgery, the atrial insertion of the anomalous pathway in the preoperative investigation was determined by using three different techniques. The atrial activation sequence during orthodromic tachycardia or ventricular stimulation was recorded in the coronary sinus by using either (a) unipolar leads from an eight-polar electrode catheter with an interelectrode distance of 1 cm, (b) bipolar leads from consecutively positioned pairs of electrodes on the same electrode catheter or (c) bipolar leads recorded at one centimeter intervals by withdrawal of the electrode catheter. The corresponding location at surgery was obtained by atrial epicardial mapping during ventricular stimulation. Each way of recording the atrial activation sequence in the coronary sinus during orthodromic tachycardia or ventricular stimulation was compared with regard to their predictive value in assessing the corresponding location by intraoperative mapping. At surgery, a visual grid system was used to define the anatomical landmarks which were located 20 mm apart.

    When the unipolar technique was used to assess the anomalous pathway location, there was a difference corresponding to a distance of 2–2.5 anatomical landmarks (48 mm) between the preoperative and intraoperative assessments. With the bipolar technique the difference was up to 3 anatomical landmarks (60 mm) while it was up to 4.5 anatomical landmarks (90 mm) when the withdrawal technique was employed. The unipolar technique was superior in differentiating a left lateral from a left posterior or a septal location.

    Ventricular dimensions and wall motion assessed by echocardiography in patients with arrhythmogenic right ventricular dysplasia1988In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 9, no 12, 1291-1302 p.Article in journal (Refereed)
    Abstract [en]

    Twenty patients with arrhythmogenic right ventricular dysplasia (ARVD) and 20 healthy volunteers underwent cross-sectional echocardiographic examination for the assessment of ventricular dimensions and wall motion. Right ventricular cavity diameters and wall segments were selected from the inflow and outflow tracts and the right ventricular body. The measurement error for measuring cavity dimensions was low throughout and the reproducibility of wall motion scoring was high in both the normal subjects and the patients. All except one patient had increased dimensions and/or abnormal wall motion in the right ventricle. The right ventricular inflow tract was dilated in nine patients, the outflow tract in 11 patients and the short- or long-axis diameters of the right ventricular body were increased in seven patients. Right ventricular wall motion abnormalities, being the most frequent finding, ranged from mild hypokinesia only to dyskinesia or sacculations, and were fairly evenly distributed among the segments studied. Left ventricular abnormalities, found in eight patients, were generally mild. Cross-sectional echocardiography thus provides highly reproducible measurements of right ventricular size and contraction patterns even in patients with wall shape deformities, and is therefore a feasible non-invasive method for the evaluation of right-sided myocardial abnormalities in patients with ARVD. The diagnostic accuracy of this technique warrants further clarification.

    Quantitative analysis of the signal-averaged QRS in patients with arrhythmogenic right ventricular dysplasia1988In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 9, no 3, 301-312 p.Article in journal (Refereed)
    Abstract [en]

    Temporal signal averaging of the surface QRS (VI + V3 + V5) was performed in 16 patients with arrhythmogenic right ventricular dysplasia and in 16 normal subjects. The differences between ARVD patients and normals were large for the filtered QRS duration (FQRSd) (146.2±18.9 vs. 91.8±4.1ms, P<000001), the late potential duration (LPd) (83.5±23.3 ms vs. 23.6±4.6ms, P< 0.00001), the LPd/ FQRSd ratio (53.9± 10.1% vs. 25.8±5.1%, P <0.00001), the filtered QRS amplitude (234.0±61.1μV vs. 429±942 fiV, P <0001), and the root mean square voltage of the signals in the terminal 40 and 50 ms of the FQRS (RMS40 and RMS50) (18.4± 10.0μV vs. 118.4±49.8p.V, P<0.0005 and 27.9± 19.2μV vs. 217.0±66.3fiV, P<0000002). RMS50 <40μV discriminated best between ARVD and normals (81% sensitivity and 100% specificity). The right-sided predominance of the abnormalities in ARVD was demonstrated by the significantly longer FQRSd and LPd, and the higher ratio LPd/FQRSd in right than in left precordial leads. The arrhythmia susceptibility did not seem to influence the presence of or properties ofLP in the ARVD group. Patients with multiple QRS morphologies during ventricular tachycardia (VT) had, compared with patients with only one type of VT, longer LPd (108.3 ±46.4 ms vs. 64.2 ±31.7 ms, P<0.02) and lower RMS40 voltage (9.4±9.9 μV vs. 25.4±21.6 μV, P<0.05). The relative heart volume was positively correlated with delayed activity, but an enlarged heart was not apre-requisitefor the presence ofLP. The method thus identifies changes which are specific to ARVD. The findings indicate that certain electrical or morphological conditions are required for the occurrence of arrhythmias.

    A randomized double-blind study of epicardial left atrial cryoablation for permanent atrial fibrillation in patients undergoing mitral valve surgery: the SWEDish Multicentre Atrial Fibrillation study (SWEDMAF)2007In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 28, no 23, 2902-2908 p.Article in journal (Refereed)
    Abstract [en]

    AIMS: The efficacy of epicardial left atrial (LA) cryoablation in eliminating atrial fibrillation (AF) in patients undergoing mitral valve surgery (MVS) is unknown. We hypothesized that MVS combined with LA cryoablation is superior to MVS alone. METHODS AND RESULTS: Sixty-nine patients with permanent AF, included at four centres, underwent MVS with or without epicardial LA cryoablation. The primary endpoint was regained sinus rhythm. Risk factors for failed AF cryoablation were elucidated. Sixty-five out of 69 patients reached the primary endpoint. At 6 and 12 months follow-up, 73.3% of patients who underwent cryoablation had regained sinus rhythm at both follow-ups, compared with 45.7 and 42.9% of patients, respectively, who underwent MVS alone (group differences, at 6 months P = 0.024, after 12 months P = 0.013). The in-hospital complication rate was 11.4% in the MVS group and 26.5% in the cryoablation group (P = 0.110). Risk factors for failed elimination of AF by cryoablation were duration of permanent AF (P = 0.012) and presence of coronary artery disease (P = 0.047), according to multiple logistic regression analysis. CONCLUSION: This first prospective randomized study showed that combining MVS with epicardial LA cryoablation is significantly better in eliminating pre-operative permanent AF than MVS alone.

    Follow-up by repeated signal-averaged surface QRS in patients with the syndrome of arrhythmogenic right ventricular dysplasia1989In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 10, no suppl D, 54-60 p.Article in journal (Refereed)
    Abstract [en]

    Repeated signal-averaged surface electrocardiograms were recorded with a mean interval of 32·5 months (range 14 to 55 months) in 12 patients with the syndrome of arrhythmogenic right ventricular dysplasia (ARVD). The mean differences in the amplitude and duration of the filtered QRS complex (FQRS), the root mean square voltage of the last 40 ms of the FQRS and the duration of the terminal potentials of less than 25 µV were not statistically significant between the recordings. A wide spectrum of changes in the voltage and duration of the terminal potentials was observed, irrespective of the clinical susceptibility to ventricular tachycardia. Three patients developed changes suggesting a progression, with a decreased voltage and prolonged duration of the terminal potentials, and four patients showed the opposite pattern. In five patients the signals were stationary.

    It is concluded that the properties of late potentials may change with time in patients with ARVD. Follow-up by repeated signal-averaged QRS does not appear to be useful in predicting the susceptibility to ventricular tachycardia in ARVD. Its application in predicting and following progressive right ventricular morphological changes remains to be determined.
