Depression Subtypes in Systolic Heart Failure: A Secondary Analysis From a Randomized Controlled Trial.

ABSTRACT:

Background

Heart failure (HF) is associated with an elevated risk of morbidity, mortality, hospitalization, and impaired quality of life. One potential contributor to these poor outcomes is depression. Yet the effectiveness of treatments for depression in patients with HF is mixed, perhaps due to the heterogeneity of depression.

Methods

This secondary analysis applied latent class analysis (LCA) to data from a clinical trial to classify patients with systolic HF and comorbid depression into LCA subtypes based on depression symptom severity, and then examined whether these subtypes predicted treatment response and mental and physical health outcomes at 12 months follow-up.

Results

In LCA of 629 participants (mean age 63.6 ± 12.9; 43% females), we identified 4 depression subtypes: mild (prevalence 53%), moderate (30%), moderately severe (12%), and severe (5%). The mild subtype was characterized primarily by somatic symptoms of depression (e.g., energy loss, sleep disturbance, poor appetite), while the remaining LCA subtypes additionally included nonsomatic symptoms of depression (e.g., depressed mood, anhedonia, worthlessness). At 12 months, LCA subtypes with more severe depressive symptoms reported significantly greater improvements in mental quality of life and depressive symptoms compared to the LCA mild subtype, but the incidence of cardiovascular- and noncardiovascular-related readmissions, and mortality was similar among all subtypes.

Conclusions

In patients with depression and systolic heart failure those with the LCA mild depression subtype may not meet full criteria for major depressive disorder, given the overlap between HF and somatic symptoms of depression. We recommend requiring depressed mood or anhedonia as a necessary symptom for major depressive disorder in patients with HF.

Project description:BackgroundDespite evidence associating inflammatory biomarkers with worse outcomes in hospitalized adults with COVID-19, trials of immunomodulatory therapies have met with mixed results, likely due in part to biological heterogeneity of participants. Latent class analysis (LCA) of clinical and protein biomarker data has identified two subtypes of non-COVID acute respiratory distress syndrome (ARDS) with different clinical outcomes and treatment responses. We studied biological heterogeneity and clinical outcomes in a multi-institutional platform randomized controlled trial of adults with severe COVID-19 hypoxemic respiratory failure (I-SPY COVID).MethodsClinical and plasma protein biomarker data were analyzed from 400 trial participants enrolled from September 2020 until October 2021 with severe COVID-19 requiring ≥ 6 L/min supplemental oxygen. Seventeen hypothesis-directed protein biomarkers were measured at enrollment using multiplex Luminex panels or single analyte enzyme linked immunoassay methods (ELISA). Biomarkers and clinical variables were used to test for latent subtypes and longitudinal biomarker changes by subtype were explored. A validated parsimonious model using interleukin-8, bicarbonate, and protein C was used for comparison with non-COVID hyper- and hypo-inflammatory ARDS subtypes.ResultsAverage participant age was 60 ± 14 years; 67% were male, and 28-day mortality was 25%. At trial enrollment, 85% of participants required high flow oxygen or non-invasive ventilation, and 97% were receiving dexamethasone. Several biomarkers of inflammation (IL-6, IL-8, IL-10, sTNFR-1, TREM-1), epithelial injury (sRAGE), and endothelial injury (Ang-1, thrombomodulin) were associated with 28- and 60-day mortality. Two latent subtypes were identified. Subtype 2 (27% of participants) was characterized by persistent derangements in biomarkers of inflammation, endothelial and epithelial injury, and disordered coagulation and had twice the mortality rate compared with Subtype 1. Only one person was classified as hyper-inflammatory using the previously validated non-COVID ARDS model.ConclusionsWe discovered evidence of two novel biological subtypes of severe COVID-19 with significantly different clinical outcomes. These subtypes differed from previously established hyper- and hypo-inflammatory non-COVID subtypes of ARDS. Biological heterogeneity may explain inconsistent findings from trials of hospitalized patients with COVID-19 and guide treatment approaches.

Project description:ImportanceCatheter ablation for patients with atrial fibrillation (AF) and heart failure with reduced ejection fraction (HFrEF) is associated with improved left ventricular ejection fraction (LVEF) and survival compared with medical therapy. Nonrandomized studies have reported improved success with posterior wall isolation (PWI).ObjectiveTo determine the impact of pulmonary vein isolation (PVI) with PWI vs PVI alone on outcomes in patients with HFrEF.Design, setting, and participantsThis was an ad hoc secondary analysis of the CAPLA trial, a multicenter, prospective, randomized control trial that involved 11 centers in 3 countries (Australia, Canada, and UK). CAPLA featured 338 patients with persistent AF randomized to either PVI plusPWI or PVI alone. This substudy included patients in the original CAPLA study who had symptomatic HFrEF (LVEF <50% and New York Heart Association class ≥II).InterventionsPulmonary vein isolation with PWI vs PVI alone.Main outcomes and measuresThe primary end point was freedom from any documented atrial arrhythmia greater than 30 seconds, after a single ablation procedure, without the use of antiarrhythmic drug (AAD) therapy at 12 months.ResultsA total of 98 patients with persistent AF and symptomatic HFrEF were identified (mean [SD] age, 62.1 [9.8] years; 79.5% men; and mean [SD] LVEF at baseline, 34.6% [7.9%]). After 12 months, 58.7% of patients with PVI plus PWI were free from recurrent atrial arrhythmia without the use of AAD therapy vs 61.5% with PVI alone (hazard ratio, 1.02; 95% CI, 0.54-1.91; P = .96). There were no significant differences in freedom from atrial arrhythmia with or without AAD therapy after multiple procedures (PVI plus PWI vs PVI alone, 60.9% vs 65.4%; P = .73) or AF burden (median, 0% in both groups; P = .78). Mean LVEF improved substantially in PVI plus PWI (∆ LVEF, 19.3% [13.0%; P < .01) and PVI alone (18.2% [14.1%; P < .01), with no difference between groups (P = .71). Normalization of LV function occurred in 65.2% of patients in the PVI plus PWI group and 50.0% of patients with PVI alone (P = .13).Conclusions and relevanceThe results of this study indicate that addition of PWI to PVI did not improve freedom from arrhythmia recurrence or recovery of LVEF in patients with persistent AF and symptomatic HFrEF. Catheter ablation was associated with significant improvements in systolic function, irrespective of ablation strategy used. These results caution against the routine inclusion of PWI in patients with HFrEF undergoing first-time catheter ablation for persistent AF.Trial registrationhttp://anzctr.org.au Identifier: ACTRN12616001436460.
