Effects of high-intensity interval training on cardiopulmonary function and quality of life in patients with myocardial infarction: a meta-analysis.

ABSTRACT:

Background

High-intensity interval training (HIIT) is increasingly used in cardiac rehabilitation. Its effects on cardiopulmonary function and quality of life in patients with myocardial infarction (MI) require systematic evaluation.

Methods

A systematic search was conducted in PubMed, Embase, Web of Science, Cochrane Central, and CNKI from inception to April 1, 2025. Randomized controlled trials assessing the effects of HIIT on peak heart rate (HRpeak), peak oxygen uptake (VO₂peak), respiratory exchange ratio (RER), and quality of life (QOL) in post-MI patients were included. Data were synthesized using a random-effects model. Standardized mean differences (SMDs) and 95% confidence intervals (CIs) were calculated. Heterogeneity was assessed with the I² statistic, and sensit
