Redefining psychocardiology: Integrating depression management into heart failure care for enhanced long-term recovery and prognosis

Table 3 Future research priorities for integrated depression management in heart failure

Priority area	Key research question	Suggested study design	Core outcomes	Why it matters
Integrated stepped-care models	Can embedding depression treatment into optimized HF care reduce recurrent decompensation?	Pragmatic multicenter randomized trial embedded in optimized HF care	Recurrent HF hospitalization or composite HF hospitalization/all-cause death, with depression remission, self-care, and quality of life as key secondary outcomes	Directly tests whether integrated care affects both clinical and patient-centered outcomes
Implementation in real-world settings	How can screening and treatment be integrated into routine HF clinics, including rural and community settings?	Hybrid effectiveness-implementation studies; cluster-randomized trials	Reach, fidelity, feasibility, cost, equity, sustainability, and uptake	Determines whether promising models can be scaled in practice
Precision psychocardiology	Which HF patients are most likely to benefit from targeted depression interventions?	Phenotype-based prospective cohorts and stratified trials	Phenotype stability, symptom trajectories, self-care, functional status, biomarker profiles, and cardiovascular events	Moves the field beyond a one-size-fits-all approach
Digital augmentation of care	Can digital tools improve monitoring, adherence, and early symptom detection when added to standard care?	Randomized pragmatic trials or hybrid effectiveness-implementation studies	Engagement, symptom detection, adherence, self-care, quality of life, readmission	Clarifies the role of digital tools as adjuncts to care
Mechanistic research	Which biological and behavioral pathways most strongly link depression with HF progression?	Translational cohort studies with repeated biomarker and behavioral assessment	Inflammatory markers, autonomic function, sleep disturbance, physical activity, and medication adherence	Helps distinguish causal pathways from epiphenomena
Nonpharmacological intervention strategies	Which psychological or behavioral interventions are most effective in HF?	Comparative effectiveness trials	Depression severity, resilience, exercise tolerance, self-care, quality of life	Helps identify realistic, scalable, and phenotype-sensitive intervention packages
