A Pilot Feasibility Study in Recovered Heart Failure (TRED)

Brief Summary:
One third of patients diagnosed with heart failure demonstrate left ventricular reverse remodelling and recovery of cardiac function following a period of medical therapy. These patients have an excellent long-term prognosis. Whether they need to remain on long-term medical therapy is not clear. The investigators will investigate the safety of therapy withdrawal in patients with a previous diagnosis of heart failure and recovered cardiac function, in a randomised controlled trial.

Condition or disease Intervention/treatment Phase
Heart Failure Drug: Withdrawal of therapy Phase 4

Detailed Description:

Patients with a previous diagnosis of heart failure, who have recovered cardiac function, without symptoms, normal serum biomarker concentrations and who are currently still taking heart failure medications, will be recruited. Participants will be randomised to withdrawal of therapy and control arms and will undergo imaging investigations and cardiopulmonary exercise tests at baseline along with serum biomarker tests. Those participants randomised to withdrawal of therapy will have a gradual, supervised reduction of medications. If, at anytime, there are signs of recurring heart failure, medications will be restarted. Participants in the control arm will continue their medical therapy as usual.

Participants will be followed up with further biomarker testing, cardiopulmonary exercise testing and imaging investigations at 6 months.

The primary end-point will be a relapse in heart failure, defined by adverse remodelling, increase in left ventricular size, rise in serum biomarkers or clinical evidence of heart failure as judged by the clinical team.

Primary Outcome Measures :
  1. Heart failure relapse [ Time Frame: 6 months ]
    Defined by one of the following: 1) A reduction in left ventricular ejection fraction; 2) An increase in left ventricular size; 3) An increase in serum biomarker concentration from baseline; 4) Clinical evidence of heart failure

Secondary Outcome Measures :
  1. Cardiopulmonary exercise testing with peak oxygen consumption [ Time Frame: 6 months ]
    Change in peak oxygen consumption between baseline and follow-up test

  2. Quality of life [ Time Frame: 6 months ]
    Patient questionnaires - Kansas City Cardiomyopathy Questionnaire and Heart Failure Symptom Questionnaire (symptom scores are calculated on the basis of the participants' answers to the questionnaires)

  3. Major adverse cardiovascular events (MACE) - safety end-point [ Time Frame: 6 months ]
    MACE - unplanned cardiovascular (CV) hospitalisation, CV mortality and major adverse CV events (non-fatal myocardial infarction and non-fatal cerebrovascular accident)

  4. Percentage of participants with new and sustained arrhythmias [ Time Frame: 6 months ]
    New and sustained arrhythmias diagnosed during follow-up

  5. Increase in left atrial volume as measured on cardiovascular magnetic resonance (CMR) [ Time Frame: 6 months ]
    Increase in left atrial volume as measured on CMR (in millilitres)
