UNASSIGNED: Inferior vena cava (IVC) diameter can be used to approximate right atrial pressure in @entity1 admitted for @entity712 ( @entity712 ). Recent studies linked IVC dilation to an increased risk of early re-admission and short-term mortality. Moreover, @entity177 ( @entity177 ) is an established risk factor for mortality in @entity712 and is associated with congestion. We hypothesized that the IVC diameter is a marker of all-cause mortality but its prognostic impact may be influenced by kidney function. We analyzed data of 1101 @entity1 admitted for @entity712 with available echocardiography of the IVC by chart review and death registry linkage. @entity1 were dichotomized according to a cut-off value of 21  mm. Cox proportional hazards model was used to identify mortality predictors. A dilated IVC was detected in 474 (43.1%) @entity1 . Overall, 400 (36.3%) @entity1 died within 3 years. All-cause mortality was significantly higher in @entity1 with dilated IVC [hazard ratio 1.45 (confidence interval 1.21-1.74); p   <   0.001]. However, a dilated IVC was only associated with all-cause mortality in @entity1 with @entity177 function [hazard ratio 1.60 (confidence interval 1.26-2.03); p   <   0.001] but not in @entity1 with a preserved kidney function [hazard ratio 1.04 (confidence interval 0.72-1.50); P   =   0.84]. IVC diameter was identified as an independent predictor for all-cause mortality in a Cox proportional hazards model with a significant interaction between IVC diameter and baseline kidney function. In conclusion, IVC dilation is a marker of high mortality risk in @entity1 admitted for @entity712 . However, this observation was confined to @entity1 with @entity177 .
