  • Atrial fibrillation and cause of death, sex differences in mortality, and anticoagulation treatment in low-risk patients
  • 2018
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Background: Atrial fibrillation (AF) is the most common arrhythmia but information on cause of death in patients with AF is sparse, and whether individuals at low risk of cerebral infarction (CVL) should receive antico-agulant medication is controversial. Studies of sex differences with respect to mortality risk have shown conflicting results.Methods: Data were obtained from Swedish National Registers. In Study I, there were 272 186 AF patients and matched controls and in Studies II and III, 9519 AF patients and no other diagnosis and matched controls. Study IV compared treatment with warfarin to no treatment in 48 433 patients with AF. Hazard ratio (HR) was calculated with 95% confidence intervals and outcome rates as number per 1000 person-years.Results: Ischemic heart disease (IHD) was the most common underlying cause of death and was present in 40.2% of AF patients at a HR of 1.7 (1.4-2.1). CVL/stroke was a cause of death in 13.1%, HR 2.7 (1.8-4.0). Among underlying and contributing causes of death, the most common diagnoses were IHD in 43.5%, HR 1.7 (1.4-2.0) and heart failure in 33.1%, HR 2.9 (2.2-3.7). The HRs for mortality in females with AF in age categories ≤65, 65-74, and 75-85 were 2.15, 1.72, and 1.44, and for males 1.76, 1.36, and 1.24. The rates of mortality in females with AF in age categories 55-64, 65-74, and 75-85 were 6.2, 20.7, and 57.3, and for males 8.5, 27.3, and 64.5. In patients 65-74 years, females with a CHA2DS2-VASc score of 2, and males with a score of 1 receiving warfarin treatment showed a significantly reduced risk of cerebral infarc-tion/stroke, HR 0.46 (0.25-0.83) for females and for males, HR 0.39 (0.21-0.73).Conclusions: Most common causes of death in AF patients were CVL/stroke, heart failure, and IHD. HR of mortality in patients with AF was higher in females than in males but absolute risk was higher in males with AF compared to females with AF. Anticoagulant therapy was benefi-cial in patients ≥65 years, regardless of the CHA2DS2-VASc score.

  • Gender-related differences in risk of cardiovascular morbidity and all-cause mortality in patients hospitalized with incident atrial fibrillation without concomitant diseases: A nationwide cohort study of 9519 patients
  • 2014
  • Ingår i: International Journal of Cardiology. - : Elsevier BV. - 0167-5273 .- 1874-1754. ; 177:1, s. 91-99
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Previous studies of patients with "lone" and "idiopathic" atrial fibrillation (AF) have provided conflicting evidence concerning the development, management and prognosis of this condition. Methods: In this nation-wide, retrospective, cohort study, we studied patients diagnosed with incidental AF recorded in national Swedish registries between 1995 and 2008. Controls were matched for age, sex and calendar year of the diagnosis of AF in patients. All subjects were free of any in-hospital diagnosis from 1987 and until patients were diagnosed with AF and also free of any diagnosis within one year from the time of inclusion. Follow-up continued until 2009. We identified 9519 patients (31% women) and 12,468 matched controls. Results: Relative risks (RR) versus controls for stroke or transient ischemic attack (TIA) in women were 19.6, 4.4, 3.4 and 2.5 in the age categories <55, 55-64, 65-74 and 75-85, years respectively. Corresponding figures for men were 3.4, 2.5, 1.7 and 1.9. RR for heart failure were 6.6, 6.6, 6.3 and 3.8 in women and 7.8, 4.6, 4.9 and 2.9 in men. All RR were statistically significant with p < 0.01. RR for myocardial infarction and all-cause mortality were statistically significantly increased only in the two oldest age categories in women and 65-74 years in men. Conclusions: Patients with AF and no co-morbidities at inclusion had at least a doubled risk of stroke or TIA and a tripled risk of heart failure, through all age categories, as compared to controls. Women were at higher RR of stroke or TIA than men. (C) 2014 The Authors. Published by Elsevier Ireland Ltd.

  • Patients with atrial fibrillation and outcomes of cerebral infarction in those with treatment of warfarin versus no warfarin with references to CHA(2)DS(2)-VASc score, age and sex - A Swedish nationwide observational study with 48 433 patients
  • 2017
  • Ingår i: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 12:5
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims There is controversy in the guidelines as to whether patients with atrial fibrillation and a low risk of stroke should be treated with anticoagulation, especially those with a CHA(2)DS(2)-VASc score of 1 point. In a retrospective, nationwide cohort study, we used the Swedish National Patient Registry, the National Prescribed Drugs Registry, the Swedish Registry of Education and the Population and Housing Census Registry. 48 433 patients were identified between 1 January 2006 and 31 December 2008 with incident atrial fibrillation who were divided in age categories, sex and a CHA(2)DS(2)-VASc score of 0, 1, 2 and >= 3 and they were included in a time-varying analysis of warfarin treatment versus no treatment. The primary end-point was cerebral infarction and stroke, and patients were followed until 31 December 2009. Patients with 1 point from the CHA(2)DS(2)-VASc score showed the following adjusted hazard ratios (HR) with a 95% confidence interval: men 65-74 years 0.46 (0.25-0.83), men < 65 years 1.11 (0.56-2.23) and women < 65 years 2.13 (0.94-4.82), where HR < 1 indicates protection with warfarin. In patients < 65 years and 2 points, HR in men was 0.35 (0.18-0.69) and in women 1.84 (0.86-3.94) while, in women with at least 3 points, HR was 0.31 (0.16-0.59). In patients 65-74 years and 2 points, HR in men was 0.37 (0.23-0.59) and in women 0.39 ( 0.21-0.73). Categories including age >= 65 years or >= 3 points showed a statistically significant protection from warfarin. Our results support that treatment with anticoagulation may be considered in all patients with an incident atrial fibrillation diagnosis and an age of 65 years and older, i.e. also when the CHA(2)DS(2)-VASc score is 1.

  • Patients without comorbidities at the time of diagnosis of atrial fibrillation : causes of death during long-term follow-up compared to matched controls
  • 2017
  • Ingår i: Clinical Cardiology. - : John Wiley & Sons. - 0160-9289 .- 1932-8737. ; 40:11, s. 1076-1082
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Little is known about the long-term, cause-specific mortality risk in patients without comorbidities at the time of diagnosis of atrial fibrillation (AF).METHODS: From a nation-wide registry of patients hospitalized with incident AF between 1995 and 2008 we identified 9 519 patients with a first diagnosed AF and no comorbidities at the time of AF diagnosis. They were matched with 12 468 controls. The follow-up continued until December 2008. Causes of death were classified according to the ICD-10 codes.RESULTS: During follow-up, 11.1% of patients with AF and 8.3% of controls died. Cardiovascular diseases were the most common causes of death and the only diagnoses which showed significantly higher relative risk in patients with AF than controls (HR 2.0, 95% CI 1.8-2.3), and the relative risk was significantly higher in women than in men. Stroke was a more common cause among patients with AF, 13.1% versus 9.7% (HR 2.7, 95% CI 1.8-4.0), while cerebral hemorrhage was more common among controls, 4.7% versus 10.2% (HR 0.9, 95% CI 0.6-1.5). The time from AF diagnosis to death was 6.0 ± 3.1 years.CONCLUSIONS: In patients with incident AF and no known comorbidities at the time of AF diagnosis, only cardiovascular diseases were more often causes of death as compared to controls. Women carried a significantly higher relative risk than men.

  • What do patients with incident atrial fibrillation and no comorbidities at the time of diagnosis die of?

  • Konferensbidrag (refereegranskat)abstract
    • Introduction: Little is known about the long-term mortality risk and the causes of death in patients without comorbidities at the time of diagnosis of atrial fibrillation (AF).Purposes: To identify the causes of death in patients with AF and without comorbidities at the time of AF diagnosis.Methods: We identified 9 519 patients with first diagnosed AF and no co-morbidities at the time of AF diagnosis in a nation-wide registry of patients hospitalized between 1995 and 2008. They represented 3.5% of the original cohort of 271186 patients hospitalized with incident AF. Patients with any diagnosis from ICD9 and ICD10 at the time of AF diagnosis wereexcluded. They were matched for age, sex and calendar year of AF diagnosis with 12 468 controls. The follow-up continued until December 2008. Causes of death were classified according to the ICD-10 codes.Results: During follow-up, 11.1% and 8.3% of patients with AF and controls died, HR 1.3, 95% CI 1.2–1.4. Most of the difference was explained by deaths of cardiovascular causes, 8.3% versus 3.9%, (HR 2.0, 95% CI 1.8–2.3). The cause of death pattern was the same in controls although at much lower rates. The age adjusted relative risk was higher in women than in men, HR 2.3, 95% CI 1.9–2.8 versus HR 1.7, 95% CI 1.4–2.0. Myocardial infarction was the most common cardiovascular cause of death but was less common among patients with AF than in controls, 20.5% versus 32.0%. Stroke was a more common cause among patients with AF, 13.1% versus 9.7% (HR 2.7, 95% CI 1.8–4.0), while cerebral hemorrhage was more common among controls, 4.7% versus 10.2% (HR 0.9, 95% CI 0.6–1.5). The time from AF diagnosis to death was 6.0±3.1 years, as compared to the time from inclusion to death, 5.8±3.1 years, in controls.Conclusions: Only cardiovascular diseases were more often causes of death than in controls. Women carried a significantly higher relative risk than men. The duration between AF diagnosis and death suggests that there is often time enough for early intervention with antithrombotic therapy, rhythm and/or rate control and treatment of risk factors as they appear. Interestingly, controls had the same cause of death pattern although at much lower rates.

  • Assessment of Atrial Fibrillation–Specific Symptoms Before and 2 Years After Atrial Fibrillation Ablation : Do Patients and Physicians Differ in Their Perception of Symptom Relief?
  • 2017
  • Ingår i: JACC. - : Elsevier. - 2405-500X .- 2405-5018. ; 3:10, s. 1168-1176
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: The aim of this study was to evaluate patient-reported and physician-assessed atrial fibrillation (AF)–related symptoms after AF ablation.Background: Success of AF ablation is usually defined as freedom from AF, although symptom relief is often patients’ desire.Methods: Symptom relief was assessed as perceived by patients using the short, validated, AF-specific symptom questionnaire AF6 and as classified by physicians using the European Heart Rhythm Association (EHRA) classification at baseline and 6, 12, and 24 months after AF ablation. Recurrence of arrhythmia was documented by continuous electrocardiographic monitoring.Results: In total, 54 patients completed the 24-month follow-up. All 6 items on the AF6, AF6 sum score, and EHRA class improved significantly over time. The greatest improvement was seen during the first 6 months after ablation, but AF6 scores showed continued improvement up to 12 months, in contrast to EHRA class. There was a low correlation between AF6 score and EHRA class, but the predictive ability was low. Both AF6 scores and EHRA class were significantly correlated with AF burden at all times after ablation. A change of >9 points in AF6 sum score corresponded to a meaningful reduction in symptom severity.Conclusion: Patient-reported and physician-assessed outcomes were both useful in assessing symptom relief after AF ablation, although patient-reported outcomes were more sensitive tools. There was also a discrepancy between patient-reported and physician-assessed outcomes after ablation. Freedom from AF and a low AF burden most often resulted in a reduction of symptoms, but symptom relief also occurred despite little effect on the arrhythmia.

  • Catheter ablation for atrial fibrillation : effects on rhythm, symptoms and health-related quality of life
  • 2018
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Background: AF ablation is an increasingly used treatment in patients with AF to improve patient-reported outcomes (PROs). Atrioventricular junction ablation (AVJA) is a palliative treatment option in therapy refractory AF that improves PROs but renders the patient pacemaker dependent.Aims: To evaluate rhythm control and PROs before and up to two years after AF ablation. To analyze the long-term incidence of and predictors of hospitalization for HF and all-cause mortality in patients who underwent AVJA and right ventricular pacing.Methods and Results: Fifty-four patients underwent AF ablation and both continuous rhythm monitoring via an implantable loop recorder (ILR) and intermittent rhythm monitoring three, six, 12 and 24 months after ablation. 76 % of patients had at least one AF recurrence, of whom 24 % were only detected by ILR. One third of symptom recordings did not show AF. The AF-specific AF6 scores, physician-assessed EHRA symptom class and both SF-36 summary scores all improved significantly from before to two years after ablation. There was a weak correlation between the change in AF6 scores and EHRA class from before to six and 12 months but not to 24 months after ablation. Responders to ablation (AF burden < 0.5 %), reached age- and sex-matched norms in all SF-36 domains, but non-responders only in social functioning and MCS. All AF6 scores showed at least moderate improvement in both responders and non-responders. Higher AF burden was independently associated with poorer PCS and AF6 scores. In 162 patients who underwent AVJA, hospitalization for HF occurred in 20 % of patients (two-year cumula-tive incidence 9.1 %) and 22 % died (two-year cumulative incidence 5.2 %) during a median follow-up of five years. QRS ≥ 120 ms and left atrial diame-ter were independent predictors of hospitalization for HF, and hypertension and previous HF of death.Conclusions: Continuous rhythm monitoring was superior to intermittent monitoring. The AF-specific AF6 was more sensitive to changes related to AF burden after AF ablation than both EHRA class and the SF-36. The long-term hospitalization rate for HF and all-cause mortality was low after AVJA.

  • Does zero atrial fibrillation burden after atrial fibrillation ablation mean that patients are free of symptoms?
  • 2017
  • Ingår i: Europace, Supplements. - : Oxford University Press. - 1099-6044 .- 1749-365X. ; 19:Duppl. 3, s. iii264-iii264
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Success of atrial fibrillation (AF) ablation is usually defined as freedom of AF, although symptomatic relief often is what the patient’s desire. After ablation the proportion of ‘silent’ AF increases and success based on symptomatic AF recurrence may be overestimated.Purpose: To investigate the symptomatology of patients who are truly free of AF after ablation.Methods: In 57 patients the symptomatology after AF ablation was assessed as perceived by the patient using a validated AF-specific symptom questionnaire (AF6) and the overall treatment effect (OTE), and as classified by the physician using the EHRA score, at baseline, 6, 12 and 24 months. The cardiac rhythm was continuously monitored by an implantable loop recorder throughout the 2-year follow-up.Results: At 6, 12 and 24 months 14 (26%), 23 (43%) and 23 (43%) patients had an AF burden 0% during the past 6 months, and 13 of them had an AF burden 0% during the entire 2 year follow-up. All patients reported ‘OTE better’ at all time-points. All patients were also classified into EHRA I at 6 months. Being completely free of AF for six months periods did not mean complete freedom of symptoms, but the median AF6 sum score was consistently low with a narrowing IQR over time, 0 (IQR 0-27), 0.5 (IQR 0-7) and 0 (IQR 0-11) at 6, 12 and 24 months. At 6 months 8/14 patients (57%) scored AF6=0, the others 6, 11, 26, 28, 30 and 46 points. At 12 months 13/23 patients (56%) scored AF6=0, the others 1,1,3,3,5,7,7,7,14 and 22 points. At 24 months 12/23 (52%) patients scored AF6=0, the others 1, 1, 2, 4, 9, 11, 17, 20, 24, 32 and 42 points. Among the AF6 items, ‘worry/anxiety due to AF’ was the most common, while ‘tiredness due to AF’ was the highest scoring item. In the patients with AF burden 0% during the entire 2-year follow-up all patients were improved in OTE and all patients were classified into EHRA class I at all times after ablation and the median AF6 sum score was 4 (IQR0-28), 0.5 (IQR 0-8) and 1 (0-5) at 6, 12 and 24 months after ablation.Conclusions: Sudden elimination of AF by ablation does not automatically eliminate all symptoms that the patients associated with AF, but all patients felt better and were classified in EHRA class I at all time-points. Less than a half of the patients at any time-point scored some symptoms, but the symptoms gradually decreased over time, especially between 6 and 12 months.

  • Patient-reported outcomes in relation to continuously monitored rhythm before and during 2 years after atrial fibrillation ablation using a disease-specific and a generic instrument
  • 2018
  • Ingår i: Journal of the American Heart Association. - : Wiley-Blackwell Publishing Inc.. - 2047-9980. ; 7:5
  • Tidskriftsartikel (refereegranskat)abstract
    • Background--Atrial fibrillation (AF) ablation improves patient-reported outcomes, irrespective of mode of intermittent rhythm monitoring. We evaluated the use of an AF-specific and a generic patient-reported outcomes instrument during continuous rhythm monitoring 2 years after AF ablation. Methods and Results--Fifty-four patients completed the generic 36-Item Short-Form Health Survey and the AF-specific AF6 questionnaires before and 6, 12, and 24 months after AF ablation. All patients underwent continuous ECG monitoring via an implantable loop recorder. The generic patient-reported outcomes scores were compared with those of a Swedish age- and sexmatched population. After ablation, both summary scores reached normative levels at 24 months, while role-physical and vitality remained lower than norms. Responders to ablation (AF burden < 0.5%) reached the norms in all individual 36-Item Short-Form Health Survey domains, while nonresponders (AF burden > 0.5%) reached norms only in social functioning and mental component summary. All AF6 items and the sum score showed moderate to large improvement in both responders and nonresponders, although responders showed significantly greater improvement in all items except item 1 from before to 24 months after ablation. Higher AF burden was independently associated with poorer physical component summary and AF6 sum score. Conclusions--The AF-specific AF6 questionnaire was more sensitive to changes related to AF burden than the generic 36-Item Short-Form Health Survey. Patients improved as documented by both instruments, but a higher AF burden after ablation was associated with poorer AF-specific patient-reported outcomes and poorer generic physical but not mental health. Our results support the use of an AF-specific instrument, alone or in combination with a generic instrument, to assess the effect of ablation. © 2018 The Authors.
