Pilot Study: Cardiovascular Events in High Risk Orthopedic Surgical Patients

This study is primarily an observational pilot study. After identifying patients as
high-risk according to the following criteria: CAD and/or CVD and/or PAD and/or >=60 years
old and at least 2 of the following - renal insufficiency, diabetes, COPD, hypertension,
active smoker (or active within 6 months of consent), cancer, congestive heart failure, or
any blood clot - they will be asked to sign a consent form. Patients surgical and hospital
course will continue as per standard of care. Prior to surgery, 8ml of blood will be
collected for to assess cardiovascular biomarkers including inflammatory, metabolic,
hypercoagulable and platelet biomarkers to be tested independently in Dr. Berger's lab in
Smilow. Study staff will perform electrocardiograms on POD 2. Results of these ECGs will
not be placed in the patients' charts. No other procedures will be done for research
purposes only.
