入选标准

  • Over the preceding 6 months have:
  • a) >= 2 paroxysmal (electrocardiographic documentation of at least 1) AR episodes lasting >Z= 1 hour in duration: (that terminate spontaneously within 7 days or cardioversion is performed within 48h of AF onset); or
  • b) electrocardiographic documentation of 1 persistent AF episode (sustained for 7>= days or cardioversion is performed more than 48H after AF onset); or
  • c) electrocardiographic documentation of 1 longstanding persistent AF episode (continuos AF of duration > 1.
  • 2.Warrant active therapy (within the past 3 months) beyond simple ongoing observation
  • 3.Be eligible for catheter ablation and =2 sequential rhythm control and/or =2 rate control drugs.
  • 4.Be =65 yrs of age, or <65 yrs with one or more of the following risk factors for stroke: Hypertension (treated and/or defined as a BP >140/90 mmHg) [90], Diabetes (treated and/or defined as a fasting glucose =126 mg/dl) [91], Congestive heart failure (including systolic or diastolic heart failure), Prior stroke, TIA or systemic emboli, atherosclerotic vascular disease (previous MI, peripheral arterial disease or aortic plaque), LA size >5.0 cm (or volume index =40 cc/m2), or EF =35. Subjects <65 yrs of age whose only risk factor is hypertension must have a second risk factor or LV hypertrophy to qualify.
  • 5.Have the capacity to understand and sign an informed consent form.
  • 6.Be =18 years of age.
  • NOTE: providing they remain realistically eligible for =2 membrane active drugs and/or =2 rate control agents. Patients receiving new drug therapy initiated within the previous 3 months may continue that therapy if randomized to the drug therapy arm.
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range 1000
  • F.1.3 Elderly (>=65 years) yes
  • F.1.3.1 Number of subjects for this age range 2000

排除标准

  • 1. Lone AF in the absence of risk factors for stroke in patients <65 years of age
  • 2. Patients who in the opinion of the managing clinician should not yet receive any therapy
  • 3. Patients who have failed >2 membrane active anti-arrhythmic drugs at a therapeutic
  • dose due to inefficacy or side effects (Table 5.2.2)
  • 4. An efficacy failure of full dose amiodarone treatment >= 8weeks duration at any time
  • 5. Reversible causes of AF including thyroid disorders, acute alcohol intoxication, recent
  • major surgical procedures, or trauma
  • 6. Recent cardiac events including MI, PCI, or valve or bypass surgery in the preceding 3
  • 7. Hypertrophic obstructive cardiomyopathy (outflow track)
  • 8. Class IV angina or Class IV CHF (including past or planned heart transplantation)
  • 9. Other arrhythmias mandating anti-arrhythmic drug therapy (i.e. VT, VF)
  • 10. Heritable arrhythmias or increased risk for torsade de pointes with class I or III drugs
  • 11. Prior LA catheter ablation with the intention of treating AF
  • 12. Prior surgical interventions for AF such as the MAZE procedure
  • 13. Prior AV nodal ablation
  • 14. Patients with other arrhythmias requiring ablative therapy
  • 15. Contraindication to appropriate anti-coagulation therapy
  • 16. Renal failure requiring dialysis
  • 17. Medical conditions limiting expected survival to <1 year
  • 18. Women of childbearing potential (unless post-menopausal or surgically sterile)
  • 19. Participation in any other clinical mortality trial
  • 20. Unable to give informed consent.
  • Note: Planned atrial flutter ablation in combination with the left atrial
  • ablation is not an exclusion. Exclusion Criterion #3 includes failed membrane active antiarrhythmic drugs started within 3 months prior to enrollment.
