Quality of life following surgical repair of acute type A aortic dissection: a systematic review

Background: The outcomes of surgery for acute Stanford Type A aortic dissection (ATAAD) extend beyond mortality and morbidity. The aim of this systematic review was to summarise the literature surrounding health related quality of life (HR-QOL) following ATAAD, compare the outcomes to the standardised population, and to assess the impact of advanced age on HRQOL outcomes following surgery.

Methods: A systematic review of studies after January 2000 was performed to identify HR-QOL in patients following surgery for ATAAD. Electronic searches of three databases were performed and clinical studies extracted by two independent reviewers. Strict inclusion and exclusion criteria were applied. Quality appraisal was conducted utilizing predefined criteria on pilot forms. HR-QOL results were synthesized through a narrative review of included studies.

Results: There was significant attrition in HR-QOL of patients following surgery for ATAAD. Outcomes fared worse when compared to an age adjusted normative population. Of note, elderly patients were physically vulnerable, whereas younger populations may be more mentally vulnerable to postoperative sequalae. The included studies were quite heterogeneous in their study designs, methods, HR-QOL measures reported and follow up time-frames which limited direct comparison between studies.

Conclusion: HR-QOL outcomes are adversely affected when compared to preoperative status and physical health demonstrates significant attrition over time. HR-QOL outcomes are worse off when compared to an age matched general population. In terms of age, advancing age is associated with worse physical component scores but emotional health may fare better than younger patients.
