The primary aim of our prospective, randomized, double-blind interventional clinical trial is to determine the effectiveness of high dose atorvastatin therapy to reduce post operative cognitive dysfunction (POCD) in patients undergoing cardiac valve surgery. We hypothesize that therapy with high dose atorvastatin will significantly reduce the incidence and/or severity of POCD.

Primary Outcome Measures:
  • Neurocognitive Dysfunction [ Time Frame: 6 weeks and 1 year post surgery ] [ Designated as safety issue: No ]
    The subject will under go a battery of neurological test at baseline, 6 weeks post surgery and at 1 year post surgery to assess neurocognitive status.

Ages Eligible for Study:   50 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Fifty informed and consenting patients for cardiac valve surgery with CPB , greater than 50 years of age and under the care of one or more of the investigators or consultants will be prospectively enrolled over a one-year period (plus one-year for follow-up).

Exclusion Criteria:

  • Patients with a history of the following disease entities will be excluded:

    • symptomatic cerebrovascular disease with substantial residual deficit, alcohol abuse, psychiatric illness, renal failure (creatinine>2.0),
    • hepatic dysfunction (ALT or AST > 1.5 x ULN), history of allergy or myopathy with statin therapy, pregnant or breastfeeding women or other comorbidities that in the opinion of the investigator could limit patient participation. Exclusion criteria are designed to limit confounding and enhance differentiation of deficits related to surgery and or treatment.
    • Patients who are unable to read and thus unable to complete the neurocognitive testing will also be excluded.
    • Patients having concomitant carotid endarterectomy or other vascular surgery will also be excluded to provide a more homogeneous sample for comparison.
