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.

GDMT
NO INTERVENTIONPatients 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
EXPERIMENTALPatients 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.
Interventions
The participants underwent 36 sessions of alternating 3-min of 80% peak oxygen consumption (VO2peak) and 40% VO2peak for 30-min
Eligibility Criteria
You may qualify if:
- Patients with heart failure, diagnosed according to the Framingham HF diagnostic criteria (McKee et al. N Engl J Med 1971, 285:1441-1446), who had stable clinical presentations greater than 4 weeks and received individualized patient education under optimized guideline-based management (Mao et al.
