Anxiety or depression in heart failure across the ejection fraction spectrum

Abstract Background Anxiety or depression are commonly described in patients with heart failure (HF) but few data exist on characteristics and clinical outcomes associated with anxiety or depression across the different HF phenotypes. Purpose To assess the prevalence of patient characteristics and clinical outcomes associated with anxiety or depression in patients with HF with preserved, mildly reduced and reduced ejection fraction (HFpEF, HFmrEF, and HFrEF). Methods Patients enrolled in the Swedish Heart Failure Registry between 2000-2021 were included. Self-reported anxiety or depression was collected using EuroQoL 5-dimensional questionnaire (EQ-5D) at baseline and follow-up visits. Anxiety or depression was categorized as "not anxious or depressed", "moderately anxious or depressed" or "severe anxious or depressed". The independent associations between baseline characteristics and presence of anxiety or depression were assessed by a multivariable multinominal regression analysis. Cox proportional hazards regressions were performed to model the time to first event according to levels of anxiety or depression. Outcomes included all-cause death and all-cause hospitalizations. Results A total of 45,247 patients were included among whom 58% reported none, 38% moderate and 5% severe anxious or depressed with similar distribution across the HF phenotypes (Figure). Several characteristics were associated with anxiety or depression with the strongest ones for severe versus none being higher NYHA class (OR 3.10 (2.77-3.47)), liver disease (OR 1.99 (1.56-2.55)), in-patient setting (OR 1.62 (1.43-1.84)), smoking (OR 1.75 (1.52-2.00)) while others were inversely related including male sex (OR 0.51 (0.46-0.56)), higher age (OR 0.60 (0.53-0.67)), referral to HF nurse clinic (OR 0.82 (0.72-0.94)) and higher income level (OR 0.68 (0.62-0.76)). The risk of all-cause death and all-cause hospitalizations increased with increasing levels of anxiety or depression across all HF phenotypes during 12 months of follow up. Severe anxiety or depression had a stronger association with all-cause death in hospitalized patients and all-cause hospitalizations in out-patients. Conclusion In this large contemporary cohort of patients with HF in a real-world setting, anxiety or depression was frequently and similarly distributed across all HF phenotypes. Higher NYHA class, liver disease and in-patient setting were strongly associated with the anxiety or depression while male sex, higher age, and higher income were inversely related with anxiety or depression. Anxiety or depression was significantly associated with worse outcomes at 12 months follow up.Proportion anxiety or depression
