During mean follow-up of 13.4\u00b17.0 years, CE occurred in 131 patients and more frequently in VP than non-VP group (p&lt;0.001). However, the VP group was no longer associated with CE after taking into account other variables in multivariate analysis, which revealed AF (HR (HR)=2.08), SHD (HR=4.97), low LVEF (HR=0.98 for every 1% increase) and high age (HR=1.03 for every year of age) were independent predictors for CE. Regarding patients with SHD and\/or AF and those aged \u226575 years, Kaplan-Meier curves showed both groups had similar prognosis.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n
