Classification of cardiorenal syndorme (CRS).
| | Acute cardiorenal syndrome | CRS type 1 | Abrupt worsening of cardiac function leading to acute kidney injury (AKI) |
| | Chronic cardiorenal syndrome | CRS type 2 | Chronic abnormalities in cardiac function causing progressive chronic kidney disease (CKD) | | Acute renocardiac syndrome | CRS type 3 | Sudden worsening of renal function causing acute cardiac dysfunction | | Chronic renocardiac syndrome | CRS type 4 | Condition of primary CKD leading to an impairment of the cardiac function (ventricular hypertrophy, diastolic dysfunction) and/or increased risk of adverse cardiovascular events. | | Secondary cardiorenal syndrome | CRS type 5 | Systemic disorders (e.g., sepsis) causing both cardiac and renal dysfunction |
