Functional capacity after cardiac surgery in elderly patients.

Abstract：

OBJECTIVES:This study was performed to determine whether cardiac surgery improves functional capacity in patients > 70 years of age and to identify factors associated with good and poor functional results in this age group. BACKGROUND:Cardiac surgery has been used increasingly among older patients, but the effectiveness of surgery in this age group remains controversial. METHODS:Self-reported functional capacity was assessed by the Duke Activity Status Index preoperatively and again 1 year after coronary artery bypass or valve replacement surgery in a total of 199 patients with a mean age of 76 years (range 70 to 91). RESULTS:Functional capacity improved significantly after surgery (mean Duke Activity Status Index 27.9 at baseline vs. 36.8 at 12 months, p < 0.001), with improvements in most patients (74%). Six preoperative factors were independent predictors of less improvement in functional capacity between baseline and 1 year: smoking, female gender, higher Charlson comorbidity index, syncope, previous cardiac operation and older age. Postoperative complications were also a highly significant predictor of lower functional capacity at 1 year. CONCLUSIONS:Most older patients have meaningful improvements in functional capacity after cardiac surgery, and clinical factors appear to modify the degree of improvement attainable.
