Heart failure can impair kidney function through several mechanisms:
1. Decreased Cardiac Output: Reduced heart function leads to decreased blood flow to the kidneys, resulting in impaired renal perfusion. 2. Increased Venous Pressure: Heart failure can cause elevated venous pressure, leading to congestion in the kidneys and further impairing their function. 3. Neurohormonal Activation: The body’s compensatory mechanisms, such as the activation of the renin-angiotensin-aldosterone system (RAAS) and sympathetic nervous system, can worsen both heart and kidney function.
