Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Supervised withdrawal of cardioprotective therapies will occur in a staged fashion soon post randomisation by the research team, which includes a cardiologist. The prinicipal investigator will be responsible for the overall medication withdrawal.

Firstly, beta-blockers will be titrated down to cessation with weekly dose reductions. Subsequently, angiotensin converting enzyme inhibitors/angiotensin receptor blockers will be titrated down to cessation with weekly dose reductions. We aim for participants to cease all revelant medications within 6 weeks of randomisation.

Should participants experience symptoms suggestive of heart failure, they will be reviewed by the research team and discussed with an independent cardiologist for recommencement of medical therapy.

Adherence to withdrawal will be monitored at protocol stipulated clinical reviews.

Treatment: Other
Comparator / control treatment
Continuation of current prescribed cardioprotective therapy will occur for 6 monts post-enrollment. Medication adherence will be monitored at protocol stipulated clinical reviews.
