Key result
HIIT is linked to broader improvements in exercise tolerance than continuous aerobic training in HF.
Why the study?
Conventional aerobic training is the first choice in cardiac rehabilitation for chronic heart failure patients, but high-intensity interval training has little evidence as an alternative.
Does continuous aerobic training or high-intensity interval training improve exercise tolerance in patients with chronic heart failure?
Cohort (n=30)
Randomized for training methods (CAT vs HIIT), non-randomized for control
No
Does continuous aerobic training or high-intensity interval training improve exercise tolerance in patients with chronic heart failure?
Absolute Event Rate: 79% vs 110%
p-value: p=0.008
Continuous aerobic training and high-intensity interval training increase exercise tolerance in patients with chronic heart failure.
Both modalities may enhance tolerance in chronic HF; hypothesis-generating, needs RCTs before guiding practice.

Busin et al. (2021) conducted a cohort in Chronic heart failure (CHF) (n=30). High-intensity interval training (HIIT) and Continuous aerobic training (CAT) vs. Control group (no rehabilitation) was evaluated on VE/VCO2 slope (% of prediction) (p=0.008). After 10 weeks, both continuous aerobic training and high-intensity interval training increased exercise tolerance in patients with chronic heart failure, with HIIT improving more parameters.
