What Researchers Did
Researchers evaluated the effect of HBOT (five sessions at 1.2 ATA for 30 minutes each) on platelet aggregation and membrane stiffness in 24 patients with coronary artery disease and hypertension, using laser analysis and atomic force microscopy.
What They Found
HBOT sessions reduced spontaneous platelet aggregation in male patients (from 1.46 to 0.84, p < 0.05). In patients with platelet hyperaggregation, the platelet membrane became twice as elastic after HBOT, potentially reducing clot formation risk. Effects were not significant in female patients.
What This Means for Canadian Patients
Abnormal platelet aggregation increases stroke and heart attack risk in Canadians with cardiovascular disease. This small study suggests HBOT may have an anti-clotting effect in male cardiac patients by making platelet membranes more flexible. This is an understudied potential benefit worth exploring in Canadian cardiovascular research.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The study was small (24 patients) and used a non-standard HBOT protocol at 1.2 ATA -- much lower than clinical therapeutic pressures; results may not apply to standard HBOT sessions.
