Morphofunctional assessment of platelet activity correction in hyperbaric blood oxygenation

100 patients with functional class II-III exertional angina were examined. The subjects underwent a 10-day course of hyperbaric oxygenation (HBO) in the 1.2 ATA mode for 40 minutes, against the background of standard therapy for coronary heart disease (IHD). Before and after HBO, the platelet link of hemostasis and the elastic properties of the platelet membrane were assessed. Assessment of the effect of the HBO course on the functional state of platelets, depending on their aggregation activity, showed that in patients with initially normal platelet aggregation, there is a tendency to a decrease in spontaneous aggregation, in contrast to patients with initial hypoaggregation, HBO promoted a significant increase in spontaneous aggregation. The use of a 10-day course of HBO was accompanied by a reaction of reducing the elasticity of the platelet biomembrane. Key words: aggregation; atomic force microscopy; platelet membrane; hyperbaric oxygenation.
