About this trial

This is an interventional treatment trial for Paroxysmal Atrial Fibrillation, Coronary Artery Disease focused on measuring paroxysmal atrial fibrillation, CABG, pulmonary vein isolation

Eligibility Criteria

18 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • American College of Cardiology (ACC)/ American Heart Association (AHA) -Indications for CABG
  • At least 2 ECG-verified (12-channel ECG, Holter telemetry) symptomatic paroxysmal atrial fibrillation episodes within last 12 months
  • The patient's consent to participate in the study

Outcomes

Primary Outcome Measures

Progression of atrial fibrillation
Combined indicator consist of recurrence of AF, increased frequency of AF, progression to persistent AF. Atrial fibrillation is defined as atrial fibrillation paroxysm lasting at least 60 seconds. Patients with AF>0.5% were classified as non-responders.

Secondary Outcome Measures

Hospitalization due to atrial fibrillation after surgery
All cases of hospitalization due to atrial fibrillation after surgery
Cardiovascular events
All cases of stroke, cardiac infarction, thromboembolism, bleeding and death

5. Study Description

Brief Summary
The aim of this study is a comparative evaluation of progression of paroxysmal atrial fibrillation in patients with coronary artery disease after isolated CABG and CABG combined with pulmonary vein isolation. Hypothesis of the study - patients with paroxysmal atrial fibrillation and coronary artery disease after CABG in combination with isolation of the pulmonary veins have a better outcomes for the progression of AF compared with patients undergoing isolated CABG.
Detailed Description
This is a single blinded prospective randomized study involving 72 patients with paroxysmal AF and coronary artery disease. 72 patients are required to have a 80% chance of detecting, as significant at the 5% level, an increase in the primary outcome measure by 10% in the CABG + pulmonary veins isolation group over isolated CABG group. Patients are divided into two groups, group I - isolated CABG (36 patients), and group II - CABG and pulmonary veins isolation (36 patients). Randomization is conducted by using accidental sampling before operation. The blinding process is applied to a patient, who is informed about received coronary artery bypass grafting, but don't know about pulmonary vein isolation. Subcutaneous cardiac monitor is implanted to all patients for cardiac rhythm monitoring.
