According to this literature review, Cardiorenal Syndrome (CRS) and Acute Kidney Damage (AKI) are becoming more common in hospitalized patients with cardiovascular illness and continue to be linked to poor short- and long-term outcomes. Apart from supportive care and volume status management, there are no specific medications to lower mortality linked to either AKI or CRS. Prior to renal recovery, normal electrolyte, acid-base, and fluid balance may be restored with the help of acute Renal Replacement Therapies (RRTs), which include ultrafiltration, intermittent hemodialysis, and continuous RRT. The risk of mortality and long-term dependency on dialysis is elevated in patients who require acute RRT, underscoring the significance of careful patient selection. There are minimal resources available for the cardiovascular specialist despite the expanding use of RRT in the cardiac intensive care unit.
