Study 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. The TRED-HF trial investigated the impact of therapy withdrawal in this cohort and found that 40% of patients relapsed within 6 months of stopping treatment. In this follow-on study, the investigators will investigate the safety of therapy withdrawal of sodium cotransporter 2 inhibitors (SGLT2i) and mineralocorticord receptor anatagonists (MRAs) in patients with a previous diagnosis of heart failure and recovered cardiac function, in a randomised controlled trial to assess whether this maintains remission in this population.

Study Description

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. Current guideline directed treatment of patients with heart failure relies on a combination of (1) angiotensin converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARBs), (2) beta-blockers, (3) mineralocorticoid antagonists, and (4) sodium-glucose co-transporter 2 inhibitors (SGLT2i).

The TRED-HF trial, confirmed that complete withdrawal of beta-blockers, ACEi or ARBs, and MRAs resulted in relapse within 6 months in 40% of asymptomatic patients with a previous diagnosis of DCM and improved cardiac function. This confirmed that many patients have heart failure remission rather than sustained recovery and still benefit from at least some pharmacological therapy. Defining the therapies required to maintain heart failure remission is a priority for heart failure research, taking into account the changing therapeutic needs of many millions of patients following improvement in their cardiac function. In this follow-on study to the TRED-HF trial, the investigators will carry out an open-label, randomised clinical trial examining the safety and feasibility of sequential mineralocorticoid receptor antagonist (MRA) and sodium glucose co-transporter 2 inhibitor (SGLT2i) withdrawal in 50 patients with dilated cardiomyopathy who are now in heart failure remission and taking angiotensin system inhibitors and beta-blockers. Patients will have serial cardiovascular magnetic resonance (CMR) scans and circulating biomarkers after withdrawal of each therapy and will be followed for 8 months. The primary end-point will be relapse of heart failure defined by features of adverse remodelling.
