Cardiorenal syndrome is the association between cardiac failure and renal failure.
Pathology
Cardiorenal syndrome can manifest as a new onset of renal failure, or the aggravation of chronic renal failure within the ambit of an acute or chronic heart failure exacerbation. Sometimes it can occur the other way around.
Subtypes
Five different sub-syndromes are defined on the basis of the organ primarily responsible:
type 1: acute cardio-renal syndrome: acute worsening of cardiac function that determines renal dysfunction
type 2: chronic cardio-renal syndrome:
type 3: acute reno-cardiac syndrome
type 4: chronic renal-cardiac syndrome
type 5: secondary cardio-renal syndrome
