[Changes in plasma TXB2 and 6-keto-PGF1 alpha and left atrial thrombosis in mitral stenosis].
This study was performed to determine the relationship between plasma concentration of thromboxane B2 (TXB2), 6-keto-prostaglandin F1a and atrial thrombosis in patients with mitral stenosis (MS). By radioimmunoassay and pathological examination, peripheral plasma TXB2 level was remarkably higher in patients with MS and persistent atrial fibrillation (AF) than in patients with MS but without AF (P less than 0.01). Plasma TXB2 level was significantly higher in patients with than in those without atrial thrombosis (P less than 0.05). There was no significant difference in plasma 6-keto-PGF1 alpha, plasma prostanoids level in peripheral venous blood correlated closely with that in left atrial blood. Patients with high plasma TXB2 level had a greater incidence of microthrombosis.
