What Researchers Did
Researchers investigated how a single hyperbaric oxygen session, combined with common heart medications, affected heart function in 35 patients with angina.
What They Found
A single hyperbaric oxygen session (1.5 ATA for 40 minutes) lessened the indirect heart effects of nifedipine. It also increased the heart rate and contractility-reducing effects of propranolol. However, it did not change the effects of nitroglycerin.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This study only examined the effects of a single hyperbaric oxygen session, not a full course of treatment, limiting its long-term applicability.
