Trial summary

BACKGROUND Global burdens of heart failure (HF) are increasing in modern societies. High-intensity interval training (HIIT) increases peak oxygen consumption (VO2peak) in HF patients, which was hypothesized to improve the survival of HF patients. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 20 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Baseline information of all eligible candidates, including age, gender, body mass index (BMI), and disease duration were recorded. Serum low-density lipoprotein (LDL), creatinine (Cre), high sensitivity C-reactive protein (hs-CRP), glycohemoglobin (Hba1c), and b-type natriuretic peptide (BNP) were evaluated during the follow-up. Each blood sampling for BNP analysis and short form-36 health survey (SF-36) of physical component score (PCS) and mental component score (MCS) for qualities of life were performed just before each cardiopulmonary exercise test and echocardiographic examination.

Who may be able to join

  • From January 1st, 2009 to December 31st, 2016, HF patients, defined according to the European society of cardiology, with stable clinical status greater than 4 weeks after optimal treatment were enrolled in the study.

Who cannot join

  • Those, who were ≥ 80 years and < 20 years, unable to perform exercise caused by other non-cardiac disease, pregnant, future cardiac transplantation within 6 months, uncompensated HF patients, pacemaker patients, and renal patients with estimated glomerular filtration rate < 30 ml/min/1.73m2, were not candidates in the study. Patients had absolute contraindications for cardiopulmonary exercise test (CPET) and aerobic activities, suggested by the American College of Sports Medicine (ACSM), were also excluded in the study.

About this study

Official title: Impacts of High-intensity Interval Training on Long-term Survival of Heart Failure Patients

BACKGROUND Global burdens of heart failure (HF) are increasing in modern societies. High-intensity interval training (HIIT) increases peak oxygen consumption (VO2peak) in HF patients, which was hypothesized to improve the survival of HF patients.

OBJECTIVES The cohort study aimed to highlight the effect of HIIT on long-term survivals of HF patients.

METHODS 329 HF patients, enrolled between 2009 and 2016, received multidisciplinary disease management program (MDP). They had cardiopulmonary exercise test for peak exercise capacity (VO2peak), echocardiographic examination for left ventricular ejection fraction (LVEF), LV end-diastolic diameter (LVEDD), and LV end-systolic diameter (LVESD), b-type natriuretic peptide (BNP), and quality of life questionnaire. HF patients with LVEF≤ 40% (HFrEF) and HF patients with LVEF> 40% (HFpEF) underwent≥ 36 times of HIIT. HFrEF and HFpEF patients were classified as the MDP group. Generalized estimating equation (GEE) was used to estimate the interaction between time and VO2peak, LVEF, LVEDD, LVESD, and BNP during the follow-up. Survival analysis was conducted to assess effects of HIIT on the long-term survival of HF during at end of the study.

What participants receive

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

  • High-intensity interval trainingBehavioural

    Patients warmed up for 3 min at 30% of peak oxygen consumption (VO2peak). Five 3-minute intervals at 80% of VO2peak and each interval was separated by 3-minute exercise at 40% of VO2peak. The exercise session was terminated by 3-minute cool-down at 30% of VO2peak. All subjects used a EKG and BP monitors as indicators of the assigned exercise intensity. Borg 6-to-20 scale was used to assess the rate of perceived exertion during and after each exercise session. Patients suffering unstable hemodynamic, ischemic cardiac symptoms/signs, and uncontrolled arrhythmia were instructed to immediately terminate exercise training.

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Failure and Cardiac Rehabilitation, run by Chang Gung Memorial Hospital.

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 1 inclusion and 1 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?

The record says: finished, as of the sponsor's last update on 10 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

all-cause death (time frame: 2009/1/1 to 2016/12/31). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03245125, which also lists 2 linked publications.

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 10 Aug 2017.
