其他:Additional Participants Included Only in Safety Set
Participants who were only randomized to an earlier version of the Clinical Investigational Plan and were only analyzed for the secondary safety outcome.
The randomization under the previous version was not pertinent to the primary or secondary outcomes, and thus are combined into one group for the main analysis.
|
No intervention was assigned due to not being randomized under the final version of the investigational plan
|
|
其他:Participants Not Included in Study Analyses
Patients who were, with one exception, exited prior to randomization.
The exception was a patient who was ineligible for the study analyses due to being enrolled under the previous version of the investigational plan with a pre-existing LINQ device, and thus ineligible for the Analysis Set or the Safety Set.

No intervention was assigned due to not being randomized under the final version of the investigational plan

Safety of Patient Management Pathway - Proportion of PRN Medication Interventions With Associated PRN Medication Intervention Related Serious Adverse Events (SAEs)
大体时间:From 6 weeks after installation of RAMware through the duration of follow-up for Intervention arm subjects, and from the conclusion of the 13-month randomized period through the duration of follow-up for Observation arm subjects, up to 3 years.
|
The proportion of PRN medication interventions with one or more associated medication intervention related serious SAEs as adjudicated by the independent Clinical Events Committee will be evaluated.
The objective is met when the point estimate for the event rate is less than or equal to 0.05 (5%).
|
From 6 weeks after installation of RAMware through the duration of follow-up for Intervention arm subjects, and from the conclusion of the 13-month randomized period through the duration of follow-up for Observation arm subjects, up to 3 years.

Efficacy of Patient Management Pathway - Hierarchical Composite of Cardiovascular Death, Heart Failure (HF) Events, Change in Kansas City Cardiomyopathy Questionnaire (KCCQ) and Change in Six-minute Walk Test Distance
大体时间:From 6 weeks after installation of RAMware to the end of the 13-month randomized period.
|
The win ratio for the hierarchical composite endpoint, defined as Intervention arm wins divided by Observation arm wins, will be evaluated using the Finkelstein-Schoenfeld test.
Analysis will include subjects with at least one "high" HF risk status during the analysis period (i.e. between 42 and 395 days post-randomization, to exclude the 6-weeks after the installation of RAMware and include data occurring prior to the 13-month timepoint).
HF event, as adjudicated by the independent Clinical Events Committee, is defined as an event requiring invasive HF therapy (e.g.
IV or subcutaneous diuretics/vasodilators/inotropes) or ultrafiltration, and includes events with or without hospitalization.
The Clinical Composite Score is used as KCCQ measure.
The primary efficacy objective is met when the win ratio is significantly larger than 1.0, with a p-value below 0.05.
