Overview

HIIT appears safe and feasible in phase II cardiac rehabilitation; leaves open cardiometabolic efficacy pending larger randomized trials.

Key Points

This study aims to evaluate the effects of high-intensity interval training on functional and cardiometabolic outcomes during cardiac rehabilitation.
Patients undergoing phase II cardiac rehabilitation with certain criteria were assigned to a HIIT program.
Compared with a historical control group who underwent standard rehabilitation from 2016 to 2024.
Assessment included functional tests such as the 6-minute walk test and cardiopulmonary exercise testing.
HIIT group showed a significant increase in VO2 peak (3.47 ± 3.88 mL/kg/min vs. 0.86 ± 2.27 mL/kg/min; p = 0.01).
Improvement in the 6-minute walk test was not statistically significant between groups (HIIT: 75.7 ± 66.4 m vs. control: 99.2 ± 75.5 m; p = 0.217).
No serious adverse events reported with HIIT and minimal symptomatic episodes occurred.

Does high-intensity interval training (HIIT) improve cardiometabolic and functional outcomes in phase II cardiac rehabilitation patients?

Population

90 phase II cardiac rehabilitation patients with complete revascularization and no angina, comparing a high-intensity interval training program to a historical standard cardiac rehabilitation control group.

Exposure

High-intensity interval training (HIIT) program

Comparator

Historical control group of patients with similar baseline characteristics who underwent standard cardiac rehabilitation between 2016 and 2024

Outcome

Cardiometabolic and functional outcomes (specifically VO2 peak and 6-minute walk test distance) and safetysurrogate

Main Result

Absolute Event Rate: 3.47% vs 0.86%

p-value: p=0.01

High-intensity interval training safely optimizes exercise capacity, specifically VO2 peak, in appropriately selected phase II cardiac rehabilitation patients compared to standard rehabilitation.
