Importance of stratifying acute kidney injury in cardiogenic shock resuscitated with mechanical circulatory support therapy

Acute kidney injury is common and frequently severe in patients in cardiogenic shock treated with short-term mechanical circulatory support. Milder acute kidney injury resolves with survival comparable to patients without acute kidney injury. Severe acute kidney injury is an independent predictor of long-term mortality. Nonetheless, many surviving patients with acute kidney injury do experience gradual renal recovery.
