Relation of New Permanent Right or Left Bundle Branch Block on Short- and Long-Term Mortality in Acute XXXX Bundle Branch Block and  @entity583 .

@entity1 @entity712 @entity6 @entity714 @entity18151 @entity5036 @entity583
UNASSIGNED: The aim of this study was to investigate the prognosis associated with @entity5036 ( @entity5036 ) depending on location, time of appearance, and duration in @entity1 with @entity583 ( @entity583 ). From January 1998 to January 2008, we recruited 5,570 @entity1 with @entity583 . Thirty-day and 7-year all-cause mortality, according to @entity5036 location, time of appearance, and duration were analyzed by multivariable analyses. @entity5036 was present in 964 @entity1 (17.3%); @entity714 ( @entity18151 ) 10.6% and @entity18151 ( @entity18151 ) 6.7%. Overall mortality rate at 30 days was 13.2% (n  = 738) and 7 years was 6.34 deaths per 100 @entity1 -year. Both @entity18151 and @entity18151 were more frequently previous, 42.9% and 58.8%. Compared with non- @entity5036 , all @entity5036 groups showed higher prevalence of co-morbidities, especially rates of @entity6 (49.0% vs 34.3%, p <0.001) and more often @entity712 during hospitalization (54.5% vs 26.6%, p <0.001). Compared with @entity18151 , @entity1 with @entity18151 had a higher prevalence of co-morbidities and a higher mortality, especially the new @entity5036 , 30 days: 52.5% versus 31.6% and 7 years (incident rate): 27.2 versus 13.3 per 100 @entity1 -year. New transient @entity5036 had lower @entity712 on admission (42.6% vs 58.3%, p  = 0.008) and 30-day mortality (20.3% vs 69.6%, p <0.001) compared with permanent in both locations. New permanent @entity18151 was independently associated with 30-day (hazard ratio [HR] 2.01, 95% confidence interval [CI] 1.45 to 2.79) and 7-year mortality (HR 3.12, 95% CI 2.38 to 4.09). New-permanent @entity18151 was independently associated with 30-day (HR 2.15, 95% CI 1.47 to 3.15) and 7-year mortality (HR 2.91, 95% CI 2.08 to 4.08). In conclusion, in @entity1 with @entity583 , the appearance of a new @entity5036 was independently associated with a higher 30-day and 7-year all-cause mortality.
