  • Ages 20 to 100 years
  • All sexes
  • Adult, Older adult

Study population: This study has a target enrollment of 126 HF patients admitted for worsening heart failure (HF) in 3 years, based on at least one symptom of HF and at least two signs of HF, and a change in medical treatment specifically targeting acute decompensated HF. We enroll those patients with reduced ejection fraction (LVEF <=40%). Patients must be at least 20 years of age or greater, able to walk at the time of enrollment, and expected to be discharged to home.

Who may be able to join

  • Patients must give written informed consent before any assessment is performed.
  • Inpatients >= 20 years of age, male or female.
  • Patients with a diagnosis of heart failure New York Heart Association (NYHA) class II-IV with BNP >=100 pg/mL or NT-porBNP >= 400 pg/mL ( >= 900 pg/mL if concomitant atrial fibrillation)
  • Left ventricular ejection fraction <= 40% by echocardiography or other methods

Who cannot join

  • Estimated survival time < 6 months
  • Long-term bedridden for more than 3 months
  • Cannot tolerate exercise test due to muscular skeletal disorder.

About this study

A previous study demonstrated that a multidisciplinary cardiac rehabilitation (CR) program was associated with reduced medium- to long-term all-cause mortality in a retrospective propensity score-matched study. The investigators will further investigate the predictors including LOXl2, cardiac MRI, and endothelial function that will benefit from a successful CR.

Read the detailed description

Acute heart failure (HF) is a major cause of morbidity and mortality worldwide. The Taiwan national health insurance launched HF post-acute care program with a multi-discipline treatment strategy to improve care quality and reduce the readmission rate on July 1, 2017. A previous study showed heart failure disease management program (HFDMP) is beneficial for reducing recurrent events of HF readmission, especially in the ischemic cardiomyopathy population. The key element of HFDMP is cardiac rehabilitation and exercise training. Lysyl oxidase-like 2 (LOXl2) is an enzyme, which crosslinks collagen in fibrotic processes such as liver cirrhosis, lung fibrosis, cardiac fibrosis, and heart failure. An animal study showed the correlation between cardiac fibrosis and LOXl2 serum level. In a previous clinical prospective cohort study (CMRPG8H1271), the investigators recruited 40 patients who were discharged from acute decompensated heart failure. During the follow-up period, 10 patients suffered from cardiovascular mortality. The investigators found that the LOXl2 level is higher in patients with mortality than without.

Cardiac fibrosis is characterized by systolic or diastolic dysfunction that results from the accumulation of extracellular connective tissue proteins in the heart's interstitium. Both clinical evidence and experimental studies have suggested that fibrotic changes in the heart are reversible.

The investigators hypothesize that multi-disciplinary cardiac rehabilitation could reverse cardiac fibrosis by decreasing LOXl2 levels and improving endothelial function via reversing endothelial to mesenchymal transition (EndMT). The investigators will enroll 126 post-acute HF patients in 3 years. The investigators will follow up on endothelial function, and LOXl2 level 6 months later. The investigators will also arrange cardiac MRI sequences, such as balanced steady-state free precession (SSFP) and late gadolinium enhancement (LGE) for the diagnosis of cardiac fibrosis. A cardiopulmonary exercise test will be arranged after discharge for phase II cardiac rehabilitation. The investigators will use all-cause mortality and HF hospitalization as our primary endpoint, life quality scores (KCCQ12), and peak VO2/kg as our secondary endpoint.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • exercise based cardiac rehabilitationBehavioural

    The types of exercise are treadmill walking/walking-jogging/jogging, ergometer cycling, stair climbing, or elliptical machine training. The training intensity is gradually increased fortnightly to reach the targeted Borg's rate of perceived exertion (RPE) of 12-14. The training duration is 40 minutes, which included 5-10 minutes of warm-up and cool-down exercises. The training frequency is three sessions per week, with 36 sessions concluding a complete course.

Study groups in NCT05498584
Study groupRoleWhat they receive
Post-acute systolic heart failure patientsPatients who received at least one exercise training section within 3 months of acute heart failure discharge are placed in the CR group. Patients will receive a multi-disciplinary disease management program by a qualified HF nursing specialist. A board-certified physiatrist prescribes moderate continuous training according to a cardiopulmonary exercise test.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. all-cause mortality

    Number of Participants That Had First Occurrence of the All-cause mortality

    Measured: up to 36 months

Secondary outcomes (3)
  1. HF readmission

    Number of participants that had first occurrence of the HF readmission.

    Measured: up to 12 months

  2. enothelial function improvement

    changes of FMD from baseline to 6 months

    Measured: up to 6 months

  3. Change From Baseline to Month 6 and Month 12 for the Kansas City Cardiomyopathy Questionnaire 12 (KCCQ 12) Clinical Summary Score

    Change from baseline to Month 6 and month 12 for the Kansas City Cardiomyopathy Questionnaire short form (KCCQ12) clinical summary score. KCCQ12 is a 12-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. KCCQ12 clinical summary score is a composite assessment of physical limitations and total symptom scores. Scores are transformed to a range of 0-100, in which higher scores reflect better health status.

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Failure; With Decompensation, run by Chang Gung Memorial Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Hsin-Yen Tsai (+886929610850, milktea588@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

all-cause mortality (time frame: up to 36 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jul 2024.
