Association of RAVI/LAVI with Survival
Patients with RAVI/LAVI ratio above the median had a greater incidence of death or LVAD (Log-rank p=<0.001) (Figure 2). When divided into quartiles, patients in quartile 3 and quartile 4 had a significantly higher incidence of death and LVAD transplantation (p=<0.001) (Figure 3). Fewer patients in the RAVI/LAVI strata above the median were discharged alive from the hospital. In a multivariable Cox proportional hazards regression model, increasing RAVI/LAVI was associated with the outcomes of death or LVAD transplantation (HR 1.71, 95% CI 1.11-2.64, chi square 5.91, p=0.010). There was no significant association with the outcome of death and LVAD transplantation with RAVI or LAVI when analyzed as independently stratified by the median (p = 0.230 and 0.250 respectively).
