A CK (Creatine Kinase) level of ≥ 5000 U/L is associated with a greatly increased risk for Acute Kidney Injury (AKI), which, if not treated promptly, can progress to kidney failure.
Here's a breakdown:
- CK Levels and AKI: Elevated CK levels, specifically at or above 5000 U/L, indicate a significant risk of AKI.
- AKI Progression: When AKI is not addressed promptly, it can lead to various complications, including:
- Fluid retention
- Electrolyte abnormalities
- Kidney failure
- Death
- Reference Information: The provided reference states that patients with CK levels of ≥ 5000 U/L have a greatly increased risk for AKI, which can lead to kidney failure (4).
| Condition | CK Level (U/L) | Risk |
|---|---|---|
| Normal Range | Varies | Generally low risk |
| Elevated CK | >5000 | Greatly increased risk of AKI and potential kidney failure |
Therefore, while not directly defining kidney failure, a CK level of 5000 U/L or greater signals a strong risk of AKI and possible progression to kidney failure if not treated.
