HIIT Improves Survival of Heart Failure Patients

August 8, 2017 updated by: Chang Gung Memorial Hospital

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

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.

Description

Inclusion Criteria:

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.

Exclusion Criteria:

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.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
HIIT subjects in HFrEF patients
heart failure patients with reduced ejection fraction (HFrEF) received at least 36 times of high-intensity interval training (HIIT)
Behavioral: High-intensity interval training
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.
MDP subjects in HFrEF patients
heart failure patients with reduced ejection fraction (HFrEF) received only multidisciplinary disease management program (MDP) and underwent less than 36 times of high-intensity interval training (HIIT) or no exercise training
Behavioral: High-intensity interval training
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.
