Brief Summary
This randomized clinical trial will test whether a multimodal anti-inflammatory program added to standard treatment improves the prognosis of patients with heart failure who have recently been hospitalized or visited the emergency department for worsening heart failure. The program combines two parts: a structured physical exercise plan and a Mediterranean diet plan, adapted to each patient. A total of 214 adults with heart failure and mildly reduced or preserved ejection fraction (LVEF 40% or higher), recent worsening of heart failure, and elevated inflammatory markers (C-reactive protein) will take part. Patients with frailty or malnutrition are excluded from the study. Patients will be recruited from heart failure clinics of participating Spanish hospitals. After agreeing to participate, patients will be randomly assigned to one of two groups: one group will continue their usual heart failure treatment, and the other will follow the same treatment plus the exercise and nutrition program delivered remotely by trained professionals for 12 months. The main question is whether the multimodal program reduces the combined occurrence of cardiovascular death, repeated heart failure hospitalizations, worsening exercise capacity (6-minute walk test), or worsening quality of life (Kansas City Cardiomyopathy Questionnaire) at 12 months. The study will also check whether the program lowers blood inflammatory and heart failure biomarkers (NT-proBNP, CA125), improves heart function on echocardiography, and whether patients' adherence to the program affects the results. All participants will continue to receive standard heart failure care; no medication is being tested, and the intervention consists of lifestyle coaching delivered by telephone or video calls.

Study Arms (2)
Multimodal anti-inflammatory intervention (structured exercise + Mediterranean diet)
EXPERIMENTALParticipants in this arm receive, in addition to standard heart failure management, a multimodal anti-inflammatory intervention for 12 months consisting of: (1) a structured, progressive physical exercise program prescribed and supervised by trained exercise professionals and (2) individualized Mediterranean diet counseling by trained nutrition professionals. Both components are delivered through remote/virtual visits with individualized recommendations and adherence monitoring. Contact begins within 10 days of randomization. Standard pharmacological treatment is maintained and managed by the treating heart failure team.
Standard heart failure management
ACTIVE COMPARATORParticipants in this arm receive standard management at the heart failure unit of their participating center, including optimization of guideline-directed medical therapy and structured clinical follow-up, for 12 months. No lifestyle intervention components are added beyond usual care.
Interventions
Usual recommendations and guideline-directed management for heart failure at the participating center's HF unit (guideline-directed medical therapy and structured clinical follow-up) for 12 months. No lifestyle intervention added beyond standard care.
Structured, progressive physical exercise program prescribed and supervised by trained exercise professionals. Delivered through remote/virtual visits with individualized recommendations and adherence monitoring, starting within 10 days of randomization and continuing for 12 months. Added to standard heart failure management.
Individualized Mediterranean diet counseling by trained nutrition professionals. Delivered through remote/virtual visits with adherence monitoring, for 12 months. Added to standard heart failure management.

- Open-label trial: participants and treating clinicians are aware of treatment assignment. A blinded, independent Clinical Events Adjudication Committee (three cardiologists external to the study) adjudicates all clinical outcome events (cardiovascular death, recurrent heart failure hospitalizations) after reviewing source documentation. Centralized computer-generated randomization with concealed allocation; the assigned arm cannot be predicted or modified by investigators.

- De-identified individual participant data will be available to any qualified researcher (academic investigators, regulatory agencies, and other researchers with a scientific interest) who provides a methodologically sound research proposal. Requests must be sent to the principal investigator (aesteban@salud.madrid.org) and will be reviewed and approved by the study coordinating center and the responsible party. Approved requesters will receive the de-identified datasets with a data dictionary, the study protocol, and the analytic code (Stata), under a signed data access agreement defining permitted use, data security requirements, and prohibition of re-identification attempts or redistribution.
De-identified individual participant data underlying the published results will be shared: baseline demographics and clinical characteristics; randomized treatment assignment; primary and secondary outcome data (cardiovascular death, recurrent heart failure hospitalizations, 6-minute walk test distance, KCCQ scores); biomarker values (NT-proBNP, CA125, C-reactive protein, neutrophil-to-lymphocyte ratio); echocardiographic parameters; and adherence data to the exercise and dietary interventions. Data will be de-identified (no direct identifiers), provided with a data dictionary, and accompanied by the study protocol and statistical analysis plan. Data will be available from 12 to 36 months after publication of the primary results, to researchers providing a methodologically sound proposal approved by the coordinating center, under a data access agreement.
