BELGIUM-HF Registry & Trial
To test the hypothesis that general practitioner's intervention triggered by an alarm generated by an algorithm based on non-invasive vital sign home telemonitoring measurements in moderate to severe heart failure patients may reduce the rate of hospitalisations for heart failure, mortality or both.
The BELGIUM-HF Registry and Trial is a study that will be conducted in two steps.
The primary objective of the registry is to identify predictors of death, heart failure recurrence requiring hospitalisation, or both, and to validate simple and robust interventional algorithms based on weight, blood pressure and pulse transmitted by a telemonitoring system and to test those algorithms in subgroups of patients.
The primary objective of the subsequent randomised trial is to demonstrate a reduction in the incidence of Heart Failure (HF)-related hospitalisations or all-cause mortality in HF subjects managed with the the telemonitoring/interventional algorithm strategy as compared with HF subjects managed with the telemonitoring/usual care strategy over a period of 6 months.

Systolic heart failure
BELGIUM-HF Registry: No intervention. Duration of the Registry: 6 months. Follow-up visits will take place at 3 and 6 months.
BELGIUM-HF Trial: General practitioner's intervention based on an alarm generated by a predefined algorithm applied to the telemonitoring system and based on daily measured blood pressure, pulse and weight versus usual care (control). Types of intervention: none, medication changes, cardiologist referral, out-patient clinic referral, emergency room referral, hospitalisation.
Duration of intervention: 6 months
Primary outcome measure
Primary outcome measures in the Randomised Trial:
1. Incidence of HF-related hospitalisations (Duration of follow-up: 6 months)
2. All-cause mortality (Duration of follow-up: 6 months)
Secondary outcome measures
The following secondary end-points in the Randomised Trial will be assessed at 3 and 6 months except the cost-effectiveness evaluation, which will be carried out after the trial:
1. To demonstrate a reduction in the combined end-point of cardiac death, HF-related hospitalisations and cardiac-related urgent visits and interventions whichever comes first in HF subjects managed with the TeleMonitoring (TM) strategy compared to the Usual Care (UC) strategy
2. To demonstrate a reduction in HF-related hospitalisations in the TM arm compared to the UC arm
3. To demonstrate a reduction in all-cause mortality in the TM arm compared to the UC arm
4. To demonstrate a reduction in cardiac mortality in the TM arm compared to the UC arm
5. To demonstrate a reduction in the number of days spent at the hospital for HF-related conditions in the TM arm compared to the UC arm
6. To determine whether TM intervention improves functional status as assessed by a 6-minute walk test
7. To demonstrate an improvement in quality of life as assessed by the Kansas City Cardiomyopathy Questionnaire (KCCQ) in the TM arm compared to the UC arm
8. To report a shift from "in-patient" to "out-patient" healthcare utilisation in the TM arm compared to the UC arm
9. To conduct a cost-benefit comparison between the two strategies

Participant inclusion criteria
BELGIUM-HF will be conducted in two steps: a prospective registry and a subsequent randomised trial. The BELGIUM-HF Registry will be completed before the BELGIUM-HF Randomised Trial starts. Patients who have been included in the Registry are eligible for the subsequent randomised trial if they meet the inclusion criteria at that time and have signed an informed consent regarding the randomised trial.
Inclusion criteria for both BELGIUM-HF Registry and Randomised Trial:
1. Subject with left ventricular systolic dysfunction, defined as a left ventricular ejection fraction < or = 40%, documented by echocardiography, contrast ventriculography or radionuclide angioscintigraphy within 6 months prior to inclusion
2. Subject has been hospitalised within the past 6 months for mild to severe heart failure defined as New York Heart Association (NYHA) class II to IV
3. Subject has received loop diuretics within 2 weeks prior to inclusion
4. Subject is at least 18 years of age
5. Subject or subject's legally representative has signed and dated the study informed consent
Target number of participants
Registry: 200 patients; Randomised trial: 500 patients
Participant exclusion criteria
1. Subject who is scheduled for corrective valve surgery or coronary revascularisation, i.e. Coronary Artery Bypass Grafting (CABG) or Percutaneous Coronary Intervention (PCI) in a near future
2. Subject who has significant concurrent illness or condition not related to heart failure (i.e. terminal malignancy), associated with a life expectancy that is anticipated to be shorter than the expected duration of the trial
3. Subject on chronic renal dialysis
5. Subject who has a health condition or psychic condition associated with poor compliance, including active alcoholism, mental illness or drug dependence
6. Subject directly involved in the execution of this protocol
