Abstract

Previous studies have demonstrated that platelet activation occurs in peripheral blood of patients with rheumatic mitral stenosis (MS). However, in patients with MS, the plasma level of soluble P-selectin (a marker of platelet activation) remains unsettled. A total of 20 patients with symptomatic MS undergoing percutaneous transluminal mitral valvuloplasty (PTMV) were studied (group 1; 16 patients in permanent atrial fibrillation, and 4 patients in sinus rhythm). The plasma levels of soluble P-selectin in the femoral vein and artery, and right and left atria before PTMV and those in the peripheral venous blood at the 1-week and 4-week follow-ups after PTMV were determined by solid-phase, sandwich, enzyme-linked immunosorbent assay. The mitral valve area was calculated by means of the Doppler pressure half-time method. In addition, we measured plasma concentrations of soluble P-selectin in the peripheral venous blood samples obtained from 22 control patients (including 14 healthy volunteers in sinus rhythm [group 2] and 8 patients in permanent lone atrial fibrillation [group 3]). The plasma levels of soluble P-selectin were significantly elevated in group 1 patients (49.78 +/- 37.72 ng/mL) [mean +/- SD] compared with group 2 (25...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
