Impact of a Treatment With Angiotensin Receptor Blocker on Outcome After Acute Kidney Injury in Patients Discharged From the ICU.

Summary

The patients discharged from intensive care units (ICU) have a high incidence of cardiovascular events and mortality rate during the year following ICU discharge. Among patients admitted to the ICU, patients with acute kidney injury (AKI) display high risk of such events. The investigators furthermore demonstrated that AKI could induce remote cardio-vascular injury and fibrosis, which may be involved in the poor prognosis of AKI. Strategies that may prevent the cardiovascular consequences of AKI in most severe patients (i.e. post-AKI ICU survivors) may therefore improve long term outcomes. AKI has been associated with activation of the renin-angiotensin-aldosterone system (RAAS). Activation of the RAAS has been further associated with long-term health consequences especially with cardiovascular damages. Potential protective effects of RAASi following acute injury have been reported in observational studies. With this randomized controlled trial, the investigators aim at investigating the impact of treatment with RAAS inhibitors after AKI on cardiovascular and kidney outcomes.
