Short-term Atorvastatin's Effect on Acute Kidney Injury Following Cardiac Surgery
Summary
Aim1: Statin naive patient's scheduled for cardiac surgery will be randomized to 80mg atorvastatin or placebo on the day prior to surgery and then 40mg daily thereafter until hospital discharge to test the hypothesis that short-term atorvastatin use decreases:
Aim2: Patients using statins preoperatively will be randomized to atorvastatin 80mg or placebo on day of surgery and 40mg or placebo on postop day 1 with resumption of preoperative statin therapy on postop day 2 to test the hypothesis that short-term atorvastatin use decreases:
1. acute kidney injury following cardiac surgery.
2. postoperative delirium following cardiac surgery.
Endpoints include glomerular filtration, urine and plasma markers of renal dysfunction, markers of oxidative stress, systemic inflammatory markers, delirium, dialysis, stroke, myocardial infarction, time to extubation, ICU length of stay, and death.

Medical and Biotech [MESH] Definitions
Acute Kidney Injury
Abrupt reduction in kidney function defined as an absolute increase in serum CREATININE of more than or equal to 0.3. mg/dl, a percentage increase in serum creatinine of more than or equal to 50%, or a reduction in urine output. Acute kidney injury encompasses the entire spectrum of the syndrome including acute kidney failure; ACUTE KIDNEY TUBULAR NECROSIS; and other less severe conditions.
Kidney Tubular Necrosis, Acute
Acute kidney failure resulting from destruction of EPITHELIAL CELLS of the KIDNEY TUBULES. It is commonly attributed to exposure to toxic agents or renal ISCHEMIA following severe TRAUMA.
Kidney Failure
A severe irreversible decline in the ability of kidneys to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal failure, either acute (KIDNEY FAILURE, ACUTE) or chronic (KIDNEY FAILURE, CHRONIC), requires HEMODIALYSIS.
Kidney Papillary Necrosis
A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.
Renal Insufficiency, Acute
Conditions in which the function of KIDNEYS deteriorates suddenly in a matter of days or even hours. It is characterized by the sudden drop in GLOMERULAR FILTRATION RATE; (GMR). The most severe stage is when the GFR drops below 15 ml per min (ACUTE KIDNEY FAILURE).
