What Researchers Did
Researchers prospectively investigated the effect of hyperbaric oxygen therapy on N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in 25 diabetic patients receiving treatment for non-healing lower extremity ulcers.
What They Found
They found that N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels significantly increased from 815 ± 1096 pg/ml to 915 ± 1191 pg/ml after hyperbaric oxygen therapy (P < 0.05). Heart rate and arterial blood pressure remained unchanged, suggesting that hyperbaric oxygen therapy induces considerable ventricular wall stress in diabetic patients.
What This Means for Canadian Patients
Canadian diabetic patients receiving hyperbaric oxygen therapy for non-healing ulcers may experience increased ventricular wall stress. Healthcare providers should consider monitoring cardiac function, such as NT-proBNP levels, more closely in these patients to mitigate potential cardiovascular complications.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation of this study is its relatively small sample size of 25 patients, which may affect the generalizability of the findings.
