Results matter together with their context: sample size, comparison method and study limitations. Below are selected publications referenced by the manufacturer.
Controlled, non-randomised study · n = 145
The publication reported a greater improvement in six-minute walking distance in the IHHT group.
Context: Pilot study; the lack of randomisation limits causal interpretation.
Randomised controlled trial · n = 127
Postoperative markers of myocardial injury were assessed. The results concern a specific protocol and patient group.
Context: Single-centre study; results should not be generalised to every IHHT application.
Randomised controlled trial · n = 34
Cognitive performance and exercise capacity were assessed alongside multimodal training.
Context: Small sample; treatment was an addition to a broader programme.
Available studies cover different populations and protocols, often with small samples. Results do not guarantee an outcome for an individual patient. Device indications are defined by its current documentation.
Manufacturer’s bibliographyThe supplied congress brochure describes a study of 36 cardiac rehabilitation patients. We treat it as a conference report, with its limitations preserved.
The numerically larger VO₂peak increase did not reach conventional between-group statistical significance (p = 0.098). No reported adverse events in this study does not imply an absence of risk in every application.
