Does Gender Affect Outcome of Cardiac Surgery in Octogenarians?

Abstract

The long-term results of cardiac surgery in 212 consecutive octogenarians (116 men, 96 women) were reviewed retrospectively. Preoperative functional status, Euroscore, and the incidences of hypertension and chronic obstructive pulmonary disease were similar in both sexes. Women had more diabetes mellitus (45% versus 25%; p < 0.05) but less renal dysfunction (16% versus 29%; p < 0.05). Men required emergency procedures more frequently (p < 0.05). Women underwent complete revascularization more often and had more arterial grafts. Hospital mortality was similar (11.5% in women versus 12.9% in men), but women had more complications (76% versus 64%), longer convalescence (24.3 versus 18.5 days), fewer psychiatric disorders (14% versus 23%) and less heart block (9% versus 19%). Men had a slightly better outcome in terms of functional class and Euroqol score during follow-up of up to 114 months. Median survival was longer in women (3.15 versus 2.96 years) but 1-, 3-, and 5-year survival rates and late deaths were similar. Outcomes appear to be equitable for both sexes among octogenarians.
