The laboratory test, C-Reactive Protein (CRP), has become well established as a marker of
inflammation. Recently a high CRP level (indicating an increase in inflammation) was
identified as a risk factor for atrial fibrillation. We are conducting this study with
patients such as yourself with atrial fibrillation who are planning to undergo cardioversion
to determine what sort of relationship exists between CRP levels and atrial fibrillation.
We will then look at success rates of converting atrial fibrillation to normal sinus rhythm,
compared to patients' CRP levels.
- Atrial fibrillation patients referred for DC cardioversion
- On stable medical therapy
- Known chronic inflammatory states such as infections, rheumatoid arthritis or known
- Patients having undergone recent surgery or who are on steroid therapy for any reason
will be excluded.
