How effective is adjunctive hyperbaric oxygen therapy (HBOT) in acute coronary syndrome (ACS)?
The incidence of adverse effects was poorly assessed by the studies. The small number of studies, the modest numbers of patients, and the methodological and reporting inadequacies of the primary studies included in this review demand a cautious interpretation. At present, the routine adjunctive use of HBOT cannot be justified.
ACS includes acute myocardial infarction and unstable angina, is common and may prove fatal. HBOT (breathing pure oxygen at high pressures in a specially designed chamber) will improve oxygen supply to the threatened heart and may reduce the volume of heart muscle that is damaged.
