Description of intervention(s) / exposure
Other interventions - Stopping Heart Failure Medication(s)

Experimental: Stop Group - This group will stop their heart failure medication(s) under the supervision of the study team. The investigators expect most participants in the STOP group to only be on beta-blockers and/or angiotensin-converting-enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARB). The ACEi or ARB will be stopped first. The ACEi or ARB will be reduced by 50% every 7 days and stopped 7 days after 25% of maximal recommended dose for HF is reached. At this point (or at baseline if only on BB), the BB dose will be reduced by 50% every 7 days then stopped once 25% of the maximal dose is reached.

No Intervention: Standard of Care Group - This group with continue with their heart failure medication(s) for at least 1 year.


Other interventions: Stopping Heart Failure Medication(s)
This group will stop their heart failure medication(s) under the supervision of the study team.

Eligibility
Key inclusion criteria
- Adult patients (age =18 years) with cancer therapy completed more than 6 months prior
(other than hormonal therapy) and no plan for further cancer treatments with potential
risk for CTRCD.

- Prior cancer therapy with anthracyclines and/ or HER2-targeted therapy.

- Prior asymptomatic, moderate CTRCD, defined using the European Society of Cardiology
criteria (=10% drop in LVEF from baseline to 40% to 49.9% OR <10% drop to 40-49.9%
with a reduction in GLS by >15% or new abnormal Troponin I/T or NT-proBNP), diagnosed
within 1 year of completing potentially cardiotoxic cancer therapy.

- Current use of =1 HF medication started for CTRCD for at least 6 months with LVEF =55%
by recently performed (=6 months) echocardiogram, normal NT-proBNP, and no symptoms
attributable to HF.

- Confirmation of LVEF =55% and normal volumes at baseline CMR (i.e., some patients
recruited based on echocardiography, may be excluded if baseline CMR LVEF/volumes are
not normal). This is included given that the primary outcome includes the use of CMR
LVEF.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- Indication for continuation of HF medications i.e., ongoing HF symptoms, chronic
kidney disease (CKD), vascular disease, atrial or ventricular arrythmias, other (note:
participants with hypertension will be switched to other guideline-based
antihypertensive therapy).

- Contraindications for CMR (e.g., MRI non-compatible implanted pacemakers).

- Patients with severe CTRCD defined as having a nadir LVEF <40% due to the known poor
prognosis in these patients.

- Continued use of loop diuretic therapy for heart failure purposes i.e., furosemide.

- Life expectancy <1 year or metastatic disease.

- Prior history of major cardiovascular event (defined as myocardial infarction,
cerebral vascular event, admission for HF) or therapeutic cardiovascular procedure
(e.g., percutaneous coronary intervention (PCI), coronary artery bypass grafting
(CABG)).

- Issues that prevent communication, understanding or presentation for study-related
visits and inability to provide informed consent.

Summary
Brief summary
Cancer therapy-related cardiac dysfunction (CTRCD) is when the heart's ability to pump
oxygenated blood to the body is compromised. It is a side effect of cancer therapy which can
occur as commonly as in 1 in 5 patients. When this occurs, heart failure medications are
started to protect the heart from progressing to heart failure. With early detection and
treatment, heart function recovers to normal in >80% of patients. Unfortunately, heart
failure medications are associated with an undesirable long-term pill burden, financial
costs, and side-effects (e.g., dizziness and fatigue). As a result, cancer survivors
frequently ask if they can safely stop their heart failure medications once their heart
function has returned to normal. Currently there is no scientific evidence in this area of
Cardio-Oncology.

To address this knowledge gap, the investigators have designed a randomized control trial to
assess the safety of stopping heart failure medication in patients with CTRCD and recovered
heart function. The investigators will enrol patients who have completed their cancer therapy
and are on heart medications for their CTRCD, which has now normalized. The investigators
will randomize patients with no other reasons to continue heart failure medications (e.g.,
kidney disease) to continuing or stopping their heart medications safely. All patients will
undergo a cardiac MRI at baseline, 1 and 5 years with safety assessments at 6-8 weeks, 6 and
9 months and 3 and 5 years. The investigators will determine if stopping medications is
non-inferior to continuing medications by counting the numbers of patients who develop heart
dysfunction by 1 year in each group.
