Fixed-effects (Mantel-Haenszel) techniques were used to calculate risk ratios (relative risk, RR) for the binary outcomes, which included: All-cause mortality, Cardiovascular mortality, Unplanned hospitalisation, HF related hospitalisation, Adverse events (for example stroke, bradycardia, hypotension, arrhythmic events, hyperkalaemia), Change in NYHA class, Change in management, HF medication use, HF advanced therapy use, including disease specific therapies, Repeat testing or additional testing, Additional revascularisation events, Patient and carer satisfaction, Successful administration of intervention, Withdrawal due to adverse events/tolerability, Medicine optimisation and adherence, Dying in preferred place of death (for palliative care patients), Adherence to intervention, and Health service use.
