Brief Summary
Up to 35% of hip fracture patients have been shown to experience heart injury after surgery, and as many as 10% have a heart attack or die in the three months after surgery. Hip and knee arthroplasty patients are also at risk of cardiovascular complications. Patients who have these complications have higher levels of inflammation postoperatively. Statins (such as atorvastatin/Lipitor) lower cholesterol and also lessen inflammation. Both of these effects are important in preventing heart attacks. Statins have been shown to reduce the risk of heart attacks in non-surgical patients, and to protect from heart attacks in patients having heart surgery. Whether statins can prevent heart attacks in orthopedic patients is not known. In this pilot study the investigators will treat 30 orthopedic surgery patients (hip fracture, hip or knee arthroplasty) with either atorvastatin or placebo (a capsule with no study drug). Patients will start the study drug prior to surgery and take it for 45 days after surgery. Neither the doctors nor the patients will know whether they are taking atorvastatin or placebo. The investigators will look for evidence of inflammation and heart injury after surgery. The investigators hypothesize that atorvastatin will lessen the degree of postoperative inflammation found in these patients. In this study, the investigators will use a very sensitive test of heart injury that can detect problems even when patients have no symptoms. The investigators hypothesize that this test will demonstrate silent heart injury in over 50% of the hip fracture patients and over 30% of arthroplasty patients in our study. The results of this trial will help us to develop a larger study in 1000 hip fracture and joint replacement patients to determine whether atorvastatin protects orthopedic surgery patients from heart injury and other complications of surgery.

Outcome Measures
Primary Outcomes (2)
Percentage of All Enrolled Patients With a Peri-operative Rise in High-sensitivity Cardiac Troponin I
The percentage of orthopedic patients with a ≥ 10 pg/mL rise in high-sensitivity cardiac troponin I (hs-cTnI) from baseline pre-operatively to post-operative day (POD)2
change from preoperative to postoperative day 2
Peri-operative Rise in High Sensitivity C-reactive Protein (Hs-CRP)
The change in the level of hs-CRP from baseline to POD2 in 20 orthopedic patients randomized (1:1) to atorvastatin 40mg versus placebo.
Change from preoperative to post-operative day 2
Secondary Outcomes (1)
Peri-operative Rise in Interleukin-6 (IL-6) Levels
Change from preoperative to postoperative day 2
Study Arms (2)
Atorvastatin
EXPERIMENTALAtorvastatin 40mg daily starting at least 4 hours prior to hip fracture surgery, or 4 days prior to hip or knee arthroplasty, and continued until postoperative day 45.

Limitations and Caveats
Small sample size: recruitment was made difficult by comorbidities in hip fracture patients that limited participation, the reluctance of arthroplasty patients to enroll in an interventional trial, and statin use in 40% of the target population.
