Clinical patient data

AF type	Age (years)	Duration^† (years)	Coronary artery disease (n)	Hypertension (n)	Left atrial diameter^* (cm)	Left ventricular end-diastolic diameter (cm)	Left ventricular ejection fraction (%)	Mild mitral regurgitation (n)	Left ventricular wall thickness (cm)
Paroxysmal	61.5 ± 9.6	1–16	1/10	3/10	4.23 ± 0.42	4.99 ± 0.43	60.5 ± 6.2	2/10	1.21 ± 0.07
Persistent	55.7 ± 7.1	1–9	0/10	6/10	4.84 ± 0.55	5.05 ± 0.63	56.8 ± 4.6	3/10	1.26 ± 0.38

Difference in diameters is significantly different (P <.02).

^†

For paroxysmal atrial fibrillation (AF), duration represents the time from onset of first symptom attributable to AF to the time of catheter ablation. For persistent AF, the duration represents the period of uninterrupted AF up to the day of catheter ablation. See text for details.
