Cardiac surgery in octogenarians.

Age as an important risk factor in surgery has always been debatable. Between January 1991 and December 1992, 35 consecutive octogenarian patients (23 males and 12 females; average age 82.3 years) were retrospectively evaluated. Twenty-five patients had only coronary artery by-pass graft operations (CABG), five had aortic valve replacements (AVR) and five had combined AVR-CABG operations. Twenty-five of the 30 patients (83%) who underwent CABG alone or a combined procedure had suffered from unstable angina. The mean ejection fraction was 40% in this group. An average of 2.8 grafts per patient was performed. The left internal mammary artery (LIMA) was-used in nine patients (30%). The average hospitalization period was 11.5 days. Operative mortality (within 30 days) was zero. Patients who underwent AVR only were hospitalized for an average of 17.6 days and there were two cases (6%) of mortality in this group. All patients who underwent AVR and CABG were discharged within 14 days. Overall complications occurred in nine patients (25.7%); cardiac arrythmias, (4) neurological deficits (2), severe wound infections (2), and adult respiratory distress syndrome (1). The use of the LIMA was not associated with an increased incidence of bleeding or sternal infection. The low rates of mortality and major complications lead us to conclude that, when indicated, surgical treatment including the use of LIMA in selected cases, should be offered to this group of patients, even in the presence of moderate LV dysfunction.
