Rat Models of Cardiorenal Syndrome and Methods for Functional Assessment.

Cardiorenal syndrome (CRS) is a clinical disorder involving combined heart and kidney dysfunction, which leads to poor clinical outcomes. To understand the complex pathophysiology and mechanisms that lie behind this disease setting, and design/evaluate appropriate treatment strategies, suitable animal models are required. Described here are the protocols for establishing surgically induced animal models of CRS including important methods to determine clinically relevant measures of cardiac and renal function, commonly used to assess the degree of organ dysfunction in the model and treatment efficacy when evaluating novel therapeutic strategies.
