What is cardio-renal syndrome CRS?

  • Covers disorders where acute or long-term dysfunction of one organ can cause acute or long-term dysfunction of the other
  • Worsening renal failure, diuretic resistance in heart failure, and worsening kidney function during heart failure are all characteristic of the disease process

There are 5 types

1. Acute CRS: abrupt worsening of heart function leading to kidney injury

2. Chronic CRS: chronic heart failure leads to progressive kidney disease

3. Acute renocardiac syndrome: abrupt kidney dysfunction leading to acute cardiac disorder

4. Chronic renocardiac syndrome: chronic kidney disease leading to decreased cardiac function

5. Systemic CRS: Systemic condition leading to both heart and kidney disease
