FS: functional status-dependent vs. non-dependent: this variable focuses on the patient’s abilities to perform activities of daily living (ADLs) in the 30 days prior to surgery. Activities of daily living are defined as ‘the activities usually performed in the course of a normal day in a person’s life’. ADLs include: bathing, feeding, dressing, toileting, and mobility. CHF, congestive heart failure; MI, myocardial infarction history; CS, history of cardiac surgery; PCA, percutaneous coronary angioplasty; PVD, peripheral vein disease; TIA, transient ischemic attack; CVA, cerebrovascular accident.
