Key result
High-intensity interval training improved peak VO2 more effectively than moderate-intensity continuous training in cardiac patients (MD 1.76 mL/kg/min; 95% CI 1.06-2.46; P<0.001).

Supports HIIT over MICT for greater peak VO2 gains in cardiac rehab; reinforces meta-analytic evidence for higher-intensity protocols.
Meta-Analysis (n=736)
Does high-intensity interval training improve aerobic capacity in cardiac patients compared to moderate-intensity continuous training?
Mean Difference: 1.76 (95% CI 1.06–2.46)
p-value: p=<0.001
High-intensity interval training improves aerobic capacity more effectively than moderate-intensity continuous training in patients with cardiac diseases.
Xie et al. (2017) conducted a meta-analysis in Cardiac diseases (n=736). High-intensity interval training vs. Moderate-intensity continuous training was evaluated on Peak VO2 (MD 1.76, 95% CI 1.06 to 2.46, p=<0.001). High-intensity interval training improved peak VO2 more effectively than moderate-intensity continuous training in cardiac patients (MD 1.76 mL/kg/min; 95% CI 1.06-2.46; P<0.001).
