Study 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.

Read the detailed description

Background: Low-grade inflammation is a key pathophysiologic mechanism in heart failure (HF), particularly in the mildly reduced or preserved ejection fraction phenotype after decompensation. Available anti-inflammatory strategies show heterogeneous evidence of clinical benefit.

Objective: To determine whether a multimodal anti-inflammatory intervention (structured exercise plus Mediterranean diet) reduces a hierarchical composite endpoint at 12 months compared with standard treatment in patients with HF and LVEF ≥40% after a recent decompensation. Secondary objectives: effect on individual events (CV death, all-cause mortality, HF decompensation, all-cause hospitalization); on biomarkers (NT-proBNP, CA125) and diastolic function (echocardiography) at 6 and 12 months; on the primary endpoint by adherence levels; and on the predictive value of the INFLA score.

Design: Multicenter, pragmatic, randomized, controlled, superiority trial (parallel assignment, 1:1).

Population: Adults with HF and LVEF ≥40%, at least one HF decompensation within the previous 4 weeks, NT-proBNP ≥300 pg/mL in sinus rhythm (≥900 pg/mL in atrial fibrillation), NYHA class I-III, systemic inflammation (CRP ≥2 mg/L and neutrophil-to-lymphocyte ratio ≥3), and frailty (FRAIL ≥3) or malnutrition (MNA-SF \<7).Sample size: 214 patients (107 per arm), allowing for 10% losses.Intervention: The experimental arm receives a structured exercise program and individualized Mediterranean diet counseling delivered by trained professionals through remote (virtual) visits during 12 months. The control arm receives standard HF management. Randomization after informed consent at HF clinic visits.

Outcomes: Primary outcome is a hierarchical composite (win ratio) at 12 months, ranked as follows: 1) cardiovascular death, 2) recurrent HF hospitalizations, 3) change in 6-minute walk test distance, 4) change in KCCQ score. Secondary outcomes: time to all-cause death or hospitalization, echocardiographic diastolic function parameters, NT-proBNP and CA125 levels at 6 and 12 months, adherence to exercise and dietary interventions, predictive value of the INFLA score.

Event adjudication: All primary, secondary and tertiary events will be adjudicated by an independent, blinded Clinical Events Adjudication Committee.

Timeline: Recruitment 12 months; follow-up 12 months; database closure and analysis thereafter. Results expected after study completion.

Start is estimated for Nov 2026; primary completion for Nov 2028, 24 months later.

Of 1,018 non-industry interventional studies with no phase under Heart Failure, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 50. This study's planned 24 months is below that.

Counting every sponsor, half of 1,220 studies reached it within 31 months; a quarter within 16 and three quarters within 53.

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
