Surgical Treatment of Concomitant Atrial Fibrillation: Focus onto Atrial Contractility

Table 5

Multiple events Cox model for absence of LA contractility recovery.

Factors	HR	95% CI	value
Duration of AF (>36 months)	1.14	1.07–1.22	0.005
PAP	1.12	1.04–1.21	0.029

AC, atrial contractility; AF, atrial fibrillation; CI, confidence interval; HR, hazard ratio; PAP, pulmonary artery pressure.
