Are indices of systemic atherosclerosis superior to ultrasound resistance indices for prediction of allograft survival?
Compared to markers of cardiovascular risk or systemic atherosclerosis, renal RI are inferior outcome predictors in unselected transplant recipients. Only in patients with mild or moderate cardiovascular risk may RI measurements allow additional risk stratification.
These analyses suggest that outcomes for patients with severe sepsis are closely related to early (baseline to day 1 here) improvement, or lack thereof, in organ function. Also, clinical improvement on subsequent days may have little additional impact on the likelihood of survival.
