Background: We analyzed the short-term and mid-term outcomes as well as the health-related quality of life (HRQOL) of octogenarians undergoing elective and urgent cardiac surgery.
Patients and methods: We retrospectively identified 688 consecutive octogenarians who underwent cardiac surgery at our center between January 2012 and December 2019. A propensity score matching was performed which resulted in the formation of 80 matched pairs. The patients were interviewed and the Short Form-36 survey was used to assess the HRQOL of survivors. Multivariable analysis incorporated binary logistic regression using a forward stepwise (conditional) model.
Results: The median age of the matched cohort was 82 years (p = 0.937), among whom, 38.8% of patients were female (p = 0.196). The median EuroSCORE II of the matched cohort was 19.4% (10.1-39.1%). The duration of postoperative mechanical ventilation was found to be independently associated with in-hospital mortality (odds ratio: 1.01 [95% confidence interval: 1.0-1.02], p = 0.038). The survival rates at 1, 2, and 5 years was 75.0, 72.0, and 46.0%, respectively. There was no difference in the total survival between the groups (p = 0.080). The physical health summary score was 41 (30-51) for the elective patients and 42 (35-49) for the nonelective octogenarians (p = 0.581). The median mental health summary scores were 56 (48-60) and 58 (52-60), respectively (p = 0.351).
Conclusion: Cardiac surgery can be performed in octogenarians with good results and survivors enjoy a good quality of life; however, the indication for surgery or especially for escalation of therapy should always be made prudently, reserved, and in consideration of patient expectations.
