@entity1 @entity1283 @entity891 @entity1000 @entity204
OBJECTIVE: To analyze the prognostic value of @entity1283 , @entity891 and cardiothoracic ratio as indicators of @entity204 and survival in @entity1 with @entity1000 . METHODS: We carried out a retrospective review of 152 @entity1 with @entity1000 diagnosed between September 1979 and March 2003. In the first 72 months, 722 exams were performed (100 in the first 15 days). STATISTICAL ANALYSIS: chi-square, Student's t test, ANOVA and Kaplan-Meier curves. Alpha = 0.05; beta = 0.80. RESULTS: The mean age at presentation was 2.2+/-3.2 years. @entity1000 incidence was higher in @entity1 younger than 2 years (76.3% - 95% CI = 68.7% to 82.8%) (p < 0.0001). Sex (p = 0.07) and color (p = 0.11) were not significant and mortality was not influenced by age (p = 0.73), sex (p = 0.78) or color (p = 0.20). Most @entity1 were severely ill (84.2% - 95% CI = 77.4% to 89.6%; functional class III and IV; p < 0.0001). All 43 @entity204 occurred in this group (p = 0.0008). @entity1283 at presentation was observed in 94.1% (95% CI = 89.1% to 97.2%) (p < 0.0001), and @entity891 in 75.6% (95% CI = 68.0% to 82.2%) (p < 0.0001). @entity891 and @entity1283 were more frequent in functional class III/IV @entity1 (RC = 8.03 - 95% CI = 2.85% to 23.1%) (p < 0.0001). @entity891 was a marker of @entity204 (RC = 3.16 - 95% CI = 1.06% to 10.07) (p = 0.0222), but not @entity1283 (p = 0.1185). Survival was influenced by both @entity1283 (p = 0.0189) and @entity891 (p = 0.0050). Mean and maximum cardiothoracic ratio were higher in the @entity204 group (0.749+/-0.053 vs. 0.662+/-0.080) (p < 0.0001) and (0.716+/-0.059 vs. 0.620+/-0.085) (p < 0.0001). ANOVA revealed a progressive decrease in cardiothoracic ratio in the survival group (p < 0.0001). CONCLUSIONS: In @entity1 with @entity1000 , the presence of @entity891 at presentation and increased cardiothoracic ratio are associated with poor survival.
