Brief Summary

Among all patients, aged between 20 and 80 years old, with heart failure (HF) underwent guideline-directed medical therapy (GDMT) in a tertiary care hospital, 40 of them with stable clinical status greater than 4 weeks were sequentially enrolled in the study. Thery were further allocated into the high-intensity interval training (HIIT) and GDMT groups. The 20 HIIT participants underwent additional 36 sessions of exercise training with alternating 80% of peak oxygen consumption (VO2peak) and 40% of VO2peak for 30 mins, whereas the remaining 20 GDMT participants received regular medication treatement. Baseline clinical information was recorded. Cardiopulmonary exercise test (CPET), 2-D echocardiography, bioimpedance analysis, questionnaire for quality of life, serum b-type natriuretic peptide (BNP), circulating microRNA (miRNA) profile and serum metabolomics before intervention were assessed. Cardiomyocytes and/or cardiac fibroblasts were harvested in 10% patient serum for cell activities, western blot, and messenger RNA studies. All the above examinations were followed after completing the exercise training in HIIT participants and 3-4 months after initial visit in GDMT participants. Parametric anslysis was used to assess the differences of continuous parameters with normal distributions. Those without normal distributions were estimated with non-parametric analysis. 2x2 ANOVA was conducted to compare differences of the circulating miRNA between the two groups of participants before and after interventions. Non-continous parameters between the two groups were assessed by chi-square test.

Study Arms (2)

GDMT

NO INTERVENTION

Patients with heart failure (HF) had stable clinical presentations for greater than 4 weeks and received individualized patient education under optimized guideline-directed medical therapy by our HF care team. The HF care team provided only individualized education related to HF and methods for self-monitoring, optimized guideline-based HF medication, and further laboratory assessments (Lee et al. Int Heart J. 2012;53:364-369). The GDMT participants did not have any additional training programs.

HIIT

EXPERIMENTAL

Patients with heart failure (HF) had stable clinical presentations for greater than 4 weeks and received individualized patient education under optimized guideline-directed medical therapy by our HF care team. The HF care team provided only individualized education related to HF and methods for self-monitoring, optimized guideline-based HF medication, and further laboratory assessments (Lee et al. Int Heart J. 2012;53:364-369). In addition to the GDMT, the HIIT participants underwent additional 36 sessions of alternating 3-min of 80% peak oxygen consumption (VO2peak) and 3-min of 40% VO2peak for 30-min.

Behavioral: high-intensity interval training

Model Details: We compares the pre- and post-high-intensity interval training (HIIT) effects between pateients with heart failure (HF) underwent guideline-directed medical therapy (GDMT) and those with additional HIIT. All patients with HF under GDMT in a tertiary care hospital were sequentially recruited. Among these participants, part of them were allocated to receive the regular medical treatment, and part of the remaining participants underwent additional 36 sessions of high-intensity interval training. Exercise performance, left ventricle morphology, body compositions, serum b-type natriuretic peptide, circulating microRNA, and serum metabolomics in the two groups before and after interventions were compared. We also compared cardiomyocytes and/or cardiac fibroblasts behaviors harvested in the serum obtained from before and after interventions in the two groups of participants.
