What Researchers Did
Researchers treated 40 seriously ill patients with acute myocardial infarction using hyperbaric oxygen therapy for an average of 4 days.
What They Found
Among 40 patients, 37 survived immediately after hyperbaric oxygen treatment, resulting in an immediate mortality of 7.5%. The total in-hospital mortality was 15%, and patients generally experienced improved pain, dyspnoea, and arrhythmias during treatment.
What This Means for Canadian Patients
While this 1969 study suggests potential benefits, hyperbaric oxygen therapy is not a current standard treatment for acute myocardial infarction. Patients experiencing a heart attack should seek immediate medical attention for established and effective treatments.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
This study was a small, uncontrolled case series, limiting the generalizability and definitive conclusions about hyperbaric oxygen efficacy.
