Do quantification of left atrial appendage spontaneous echo contrast in patients with chronic nonalvular atrial fibrillation?
Patients with chronic nonvalvular atrial fibrillation had a denser SEC in the LA appendage compared with SEC in the main LA cavity. The severity of the appendage SEC was influenced by the LA appendage function rather than its size. Quantification of SEC in the appendage, rather than main LA cavity, was more valuable for assessing embolic potential.
High-dose vitamin C supplementation once for every 2 days has stimulating effects on the Achilles tendon healing because of early angiogenesis and increased collagen synthesis in a healthy rat model. Further studies are needed to make clear the mentioned encouraging effects of the vitamin C on the Achilles tendon healing.
