This model allowed us to identify patients at high risk for developing the need for RRT postoperatively. Strategies for these patients to prevent or ameliorate acute renal failure and reduce the need for RRT postoperatively are needed.

A diagnosis of PGD portends worse outcomes including increased 30-day and 1-year mortality. The ISHLT diagnostic criteria for moderate and severe PGD identify and discriminate patients with PGD in a clinically relevant manner.

Background and Aims Non-invasive predictors identifying subjects with compensated liver disease at highest risk for transitioning to a decompensated state are lacking. We hypothesized that liver shear stiffness as measured by magnetic resonance elastography is an important non-invasive predictor of hepatic decompensation. Methods Among patients with advanced fibrosis undergoing magnetic resonance elastography (2007–11), a baseline cohort and follow up cohort (compensated liver disease) were established. Cause specific cox proportional hazards analysis adjusting for competing risks was utilized to determine the association between elevated liver shear stiffness and development of decompensation (hepatic encephalopathy, ascites, variceal bleeding). Results In the baseline cohort (n=430), subjects with decompensated liver disease had a significantly higher mean liver shear stiffness (6.8 kPa, IQR 4.9–8.5) as compared to subjects with compensated liver disease (5.2 kPa, IQR 4.1–6.8). After adjustment for Model for End Stage Liver Disease score, hepatitis C, age, gender, albumin, and platelet count, the mean liver shear stiffness (OR=1.13, 95%CI 1.03–1.27) was an independently associated with decompensated cirrhosis at baseline. Over a median follow up of 27 months (n=167), 7.2% of subjects with compensated disease experienced hepatic decompensation. In the follow up cohort, the hazard of hepatic decompensation was 1.42 (95% CI 1.16 –1.75) per unit increase in liver shear stiffness over time. The hazard of hepatic decompensation was 4.96 (95% CI 1.4–17.0, p=0.019) for a subject with compensated disease and mean LSS value ≥ 5.8 kPa as compared to an individual with compensated disease and lower mean LSS values. Conclusion Baseline liver shear stiffness assessed by magnetic resonance elastography is independently associated with decompensated liver disease.
