Cardio-Renal Syndrome and Multisystem Impact

The heart and kidneys are intricately linked, and dysfunction in one organ can lead to deterioration in the other—a phenomenon known as cardio-renal syndrome. This complex interplay involves hemodynamic changes, neurohormonal activation, inflammation, and oxidative stress. Five types of cardio-renal syndrome are recognized, based on the initiating organ and whether the dysfunction is acute or chronic. Management requires careful balancing of volume status, blood pressure, and use of medications like diuretics, angiotensin-converting enzyme inhibitors, and beta-blockers. Collaboration between cardiologists and nephrologists ensures coordinated care, especially in heart failure patients with worsening kidney function. Personalized therapies targeting both organs simultaneously are the future of integrated cardio-renal care.
