Impact and Time Course of Colchicine Therapy on C-reactive Protein Elevation in Chronic Atrial Fibrillation (AF) and Post AF Ablation

Colchicine will lower C-reactive protein (CRP) in chronic atrial fibrillation and reduce the
rise in CRP which occurs following atrial fibrillation ablation

Three groups of patients will be randomized to colchicine 0.6 mg PO BID or matching placebo:

1. Paroxysmal atrial fibrillation, pre-ablation

2. Persistent atrial fibrillation, pre-ablation

3. Chronic persistent atrial fibrillation

Inclusion Criteria:

- Group 1: Persistent or chronic AF presenting for evaluation in cardiology offices.
Diagnosis of AF will be made based on the 12 -lead surface ECG.

- Group 2: Paroxysmal AF scheduled to go AF ablation presenting to the
electrophysiology laboratory for the procedure in sinus rhythm..

- Group 3:Chronic AF scheduled to go clinically indicated AF ablation, and presenting
in the electrophysiology laboratory in atrial fibrillation .

Exclusion Criteria:

1. Abnormal liver function with elevated enzymes> 1.5 times the normal.

2. Abnormal kidney function with glomerular filtration rate < 50 ml/min

3. Increased levels of creatine kinase or known myopathy

4. Neutropenia

5. Known GI disorders

6. Women of childbearing age who have not had surgical sterilization and are not using
oral contraceptives, or who's spouse has not had surgical sterilization will be
excluded due to the length of the trial and the possibility that they could become
pregnant after entry.

7. Pregnant and lactating women

8. Lactose intolerance

9. Known sensitivity, allergy, or contraindication to colchicine use -
