Left atrial appendage thrombus: Risk factor or source of cerebral embolism in patients with nonvalvular atrial fibrillation? (part 4)

patients with nonvalvular atrial fibrillation? (part 4)

DISCUSSION
Many investigators have shown a significant correlation between an increased risk of ischemic stroke in patients with atrial fibrillation and the presence of SEC in the left atrial cavity or left atrial appendage . SEC is believed to represent a procoagulation state of blood in the fibrillating atrium, thus promoting thrombus formation . Our findings suggest that a high occurrence of SEC characterizes patients with stroke regardless of whether it is old or recent. In contrast, the incidence of LAAT among patients with SEC was highest in group R.

However, it is still not clear whether left atrial appendage thrombus (LAAT) is only a marker of an increased risk of cardiovascular damage or rather the source of cerebral embolism. The purpose of this study was to determine the role of LAAT in the pathomecha-nism of stroke. If you made a decision to treat your problem fast and efficiently, you will be pleased to find a wide selection of required medications available at the . The prices are very low and you can get your drugs by mail within a very short period.

This is especially evident when only patients with SEC are evaluated. Though one should expect that a similar proportion of patients with this sign of stasis in the left atrium have LAAT, the difference between patients with recent and old ischemic stroke was striking. This may indicate that the presence of LAAT may be directly related to individual embolic episodes, while SEC seems to be a persistent marker of increased stroke risk.
