Heart failure (HF) is a chronic condition that is characterized by a weakened and enlarged heart. It typically causes symptoms such as breathlessness and swelling of the legs, and it is a serious illness that shortens life expectancy. In recent years, new medicines have been developed that can improve heart function and help patients with HF live longer. HF patients with reduced heart function typically are recommended to take four different medicines for the rest of their lives. Some patients respond so well to treatment that their heart function and symptoms appear to recover; this is called HF in remission. While the four standard medicines have proven to increase lifespan in patients with heart failure with reduced heart function, it is not known whether they all need to be continued lifelong after recovery of the heart. Current guidelines recommend treating patients lifelong, yet this is based on limited scientific evidence. Lifelong therapy comes with disadvantages: it carries considerable costs for patients and health care systems, causes potential side effects, and makes it harder for patients to keep up with all their other medications. This study will test whether carefully reducing certain HF medicines is safe compared to continuing them. Patients with heart failure in remission will be randomly assigned to either: (1) continue all standard therapies, or (2) gradually reduce medicines to just two per day under close medical supervision. Patients will followed for two years to see whether their heart function remains stable. This will be measured by looking at echograms of the heart (echocardiograms), blood tests, and whether patients experience serious events such as hospitalizations or death. This study will investigate whether partial therapy discontinuation is safe and feasible.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Continuation of guideline-recommended medical therapy for heart failure with reduced ejection fraction (e.g., an ACE inhibitor/angiotensin-receptor blocker/angiotensin-receptor and neprilysin inhibitor, SGLT2 inhibitor, beta blocker, and/or mineralocorticoid receptor blocker).
Drug: Continuation of guideline-directed heart failure therapy
Down-titration of guideline-recommended medical therapy for heart failure with reduced ejection fraction to a combination of an ACE inhibitor or angiotensin-receptor blocker and a beta blocker.
Drug: Down-titration
The intervention involves a 3-month therapy down-titration period, during which the SGLT2 inhibitor and minerolocorticoid receptor antagonist are withdrawn, and the angiotensin receptor-neprilysin inhibitor is replaced by an ACE inhibitor or angiotensin receptor blocker. The drug formulations used per drug class correspond with the ESC guideline recommendations: * ACE inhibitor: enalapril, lisinopril, ramipril, captopril or trandolapril (at the maximally tolerated dose, according to the respective drug SmPC). * ARB (second line alternative to ACEi): valsartan, losartan or candesartan (at the maximally tolerated dose, according to the respective drug SmPC). * Beta blocker: carvedilol, metroprolol, bisoprolol or nebivolol (at the maximally tolerated dose, according to the respective drug SmPC).
The comparator involves the continuation of the maximally tolerated dose of guideline-recommended medical therapy (e.g., ACEi/ARB/ARNI, MRA, SGLT2i, and/or beta blocker) the patient is using at the time of screening. The formulations per drug class may differ according to treatment regimen at randomization, but may include: * ARNI: sacubitril/valsartan (at the maximally tolerated dose, according to the respective drug SmPC) * ACE inhibitor: enalapril, lisinopril, ramipril, captopril or trandolapril (at the maximally tolerated dose, according to the respective drug SmPC). * ARB: valsartan, losartan or candesartan (at the maximally tolerated dose, according to the respective drug SmPC). * Beta blocker: carvedilol, metroprolol, bisoprolol or nebivolol (at the maximally tolerated dose, according to the respective drug SmPC). * SGLT2 inhibitor: dapagliflozin or empagliflozin at 10 mg per day. * MRA: spironolactone or eplerenone (at the maximally tolerated dose, according to the SmPC).
Time to first occurrence of recurrent adverse remodeling, significant NT-proBNP increase or all-cause mortality.
The primary outcome is a composite of (1) adverse remodeling, defined as an LVESVi increase of more than 20% from baseline using echocardiography, (2) a significant biomarker increase, defined as an NT-proBNP increase to more than 500 pg/mL, or (3) all-cause mortality.
Time frame: From enrollment to 2 year follow-up
Time to first occurrence of cardiovascular mortality or heart failure hospitalizations
Time frame: From enrollment to 2 year follow-up
Change in quality of life
Measured as the change in the Kansas City Cardiomyopathy Questionnaire (KCCQ)-12 score. It provides a 0-100 summary score (higher is better) assessing physical limitations, symptom frequency, social limitations, and quality of life. A 5-point difference is clinically significant, with 75-100 indicating good health.
Time frame: From enrollment to 2 year follow-up
Proportion of patients requiring heart failure therapy re-initiation or intensification for any reason
Time frame: From enrollment to 2 year follow-up
