Abstract
Aim. To reveal changes in the thromboxane-prostacyclin balance and platelet aggregability in patients with various variants of minor cardiac abnormalities.
Subjects and methods: Six-five patients (mean age 23.0±0.7 years) with minor cardiac abnormalities and 10 apparently healthy individuals were examined. Platelet aggregation induced by adrenaline, adenosine diphosphate, collagen) and the plasma levels of thromboxane B2 (TxB2) and 6-keto-prostaglandin F1α (6-keto-PGF1α) were determined.
Results. Patients with abnormally located chordae (ALC) were found to have no deviations in the thromboxane-prostacyclin balance and platelet aggregability. Only decreased collagen aggregation was recorded in the groups of first-degree mitral prolapse (MP) and first-degree MP + ALC; in second-degree MP and second-degree MP + ALC, there was a reduction in platelet aggregation on all inductors and an increase in TxB2. Patients with myxomatous degeneration of the mitral valve exhibited reduced collagen-induced platelet aggregation and lower plasma 6-keto-PGF1α levels.
Conclusion. The most pronounced changes in the thromboxane-prostacyclin balance and platelet aggregability were found in patients with MP and second-degree regurgitation, three intracardiac microabnomalities, and myxomatous degeneration of the mitral valve.
