Comparison Between Right and Left Ventricular Systolic Dysfunction as a Risk Factors for Aki in Critical Care Patients

• Conditions: Acute Kidney Injury (Nontraumatic)
• Interventions: Diagnostic Test: Serum urea and creatinine and the calculated e GFR

• Registration Number: NCT03369561
• Lead Sponsor: Assiut University

Brief Summary

The cardio renal syndrome generally focuses on left ventricular function, and the importance of the right ventricle as a determinant of renal function is described less frequently. Although the risk of AKI is similar for patients with isolated LVD and isolated RVD, the severity of AKI and the associated risk of hospital mortality is highest among those with isolated RVD.

Detailed Description

The right ventricle seems to affect renal function through different mechanisms, including Venous Congestion, tricuspid regurgitation, And potential inhibitory effect on left ventricular function The most important mechanism is venous congestion, a manifestation of sodium avidity and fluid expansion, as Directly increasing renal venous pressure causes sodium retention, lowers urinary output, and decreases glomerular filtration and widely thought to explain AKI Venous pressure is directly associated with renal dysfunction, independently of ventricular function, and admission peripheral edema is associated with greater risk of AKI. Such awareness of a primary role of renal venous congestion reshapes our understanding of renal function as not simply a reflection of arterial perfusion, but rather a balance between arterial supply and venous drainage.
