Patient-reported outcomes after aortic and mitral valve surgery - results from the DenHeart Study

Background: Clinical course, co-morbidity and age often differs between patients undergoing aortic and mitral valve surgery and this might affect patient-reported outcomes. Aims: The purpose of this study was to describe differences in patient-reported physical and mental health and health-related quality of life after aortic valve or mitral valve surgery, and to identify demographic and clinical characteristics associated with worse patient-reported physical and mental health, and health-related quality of life. Methods: Patient-reported outcomes were measured at discharge as a part of a national, cross-sectional study (DenHeart). Patient-reported outcome measures included: Short-Form-12, Hospital Anxiety and Depression Scale, EuroQol-5D-5L, HeartQol and Edmonton Symptom Assessment System. Demographic and clinical information was obtained from national registers. Results: Of 354 patients (65% men, mean age: 68 years), 79% underwent aortic valve surgery. Patients who had undergone aortic valve surgery had more symptoms of anxiety compared with patients who had undergone mitral valve surgery (34% vs 17%, p=0.003, Hospital Anxiety and Depression Scale anxiety cut-off score of eight). Being female was associated with worse patient-reported outcomes on all measures, whereas being unmarried was associated with worse physical health (Physical Component Score Short-Form-12) and symptom burden (Edmonton Symptom Assessment System). Length of stay was associated with worse symptoms on EuroQol-5D-5L Visual Analogue Scale. Age and comorbidity were not associated with patient-reported outcomes. Conclusion: Patients who had undergone aortic valve and mitral valve surgery did not significantly differ in patient-reported health at discharge, except for symptoms of anxiety. Being female was the only characteristic associated with overall worse patient-reported outcomes at discharge.
