The aim of the study is to compare the effects of MV targeted ASV in addition to optimized medical therapy versus optimized medical therapy alone at 6 months in patients with acute decompensated HF. The study will also assess changes in functional parameters, biomarkers, quality of life (QOL), and sleep.

Primary Outcome Measures:
  • Global Rank Endpoint [ Time Frame: Baseline, 6 months ]
    A rank order response based on survival free from CV hospitalization and improvement in functional capacity measured by 6MWD.

Secondary Outcome Measures:
  • Six-minute Walk Distance [ Time Frame: Baseline, 6 months ]
    Change in functional parameters as measured by 6-minute walk test (6MWT)

  • NT pro-BNP [ Time Frame: Baseline, 1 month, 6 months ]
    Change in neurohumoral activation as measured by N-terminal pro b-type natriuretic peptide

  • KCCQ [ Time Frame: Baseline, 3 months, 6 months ]
    Patient-reported outcome of disease specific quality of life

  • Biomarkers [ Time Frame: Baseline, 1 month, 6 months ]
    Biomarkers of inflammation, cardiovascular and renal function (troponin I ultra-sensitive, hs-CRP, creatinine)

  • ECHO parameters [ Time Frame: Baseline, 6 months ]
    Echocardiographic parameters, including LVEF and LVESVI for patients with HFrEF, and E/e' for patients with HFpEF

  • Win Ratio [ Time Frame: 6 months ]
    Patients in the new treatment and control groups are formed into matched pairs based on their risk profiles. For each matched pair, the new treatment patient is labeled a 'winner' or a 'loser' depending on who had a CV death first. If that is not known, they are labeled a 'winner' or 'loser' depending on who had a HF hospitalization first. Otherwise they are considered tied. The win ratio is the total number of winners divided by the total numbers of losers.

  • Sleep parameters [ Time Frame: 1 week, 1, 3, and 6 months ]
    Sleep and sleep disordered breathing parameters (AHI, nocturnal hypoxemia, CSR cycle length)

  • HF Hospitalization [ Time Frame: 2 days, 1 week, 1, 2, 3, and 6 months ]
    Rates of hospitalization or urgent clinic visit for worsening of heart failure and for any reason

  • Death [ Time Frame: 2 days, 1 week, 1, 2, 3, and 6 months ]
    Rate of Cardiovascular and all-cause death

  • Time dead/hospitalized [ Time Frame: 6 months ]
    Total days dead or hospitalized at study end

  • DASI [ Time Frame: Baseline, 6 months ]
    Patient-reported outcome of disease specific quality of life

  • EQ-5D-5L [ Time Frame: Baseline, 6 months ]
    Standardized self-report questionnaire that is used as a measure of general health outcome

  • PHQ-9 [ Time Frame: Baseline, 6 months ]
    Self-administered instrument for screening, diagnosing, monitoring and measuring the severity of depression

  • PSQI [ Time Frame: Baseline, 3 months, 6 months ]
    A subjective measurement of the quality and patterns of sleep in the older adult

  • ESS [ Time Frame: Baseline, 3 months, 6 months ]
    A self-administered questionnaire which provides a measurement of the general level of daytime sleepiness
