As people age, their incidence of coronary heart disease increases. The majority of persons undergoing invasive procedures such as coronary artery bypass surgery are 65 and older. Because of population trends related to aging, it is projected that there will be exponential increases in the numbers of people requiring treatment for this health problem in the future. Changes in health care reimbursement have significantly decreased hospital length of stay, resulting in many patients completing their recovery either in a rehabilitation facility or at home. Patients with multiple preoperative comorbidities are at risk for postoperative complications. Older patients usually have more health problems after coronary artery bypass surgery because they have more risk factors prior to the procedure. It is not known whether there are differences in outcomes between comparatively older and younger patients when they are matched by risk classification. Information on the recovery of patients at home will enable nurses to meet their care needs prior to surgery and after discharge from the hospital.
