Abstract
Chordae tendineae rupture process is associated with increased production of inflammatory and angiogenesis mediators in connective tissues, which contributes to chronic inflammation and pathogenesis of degenerative chordae. A few trace elements are known to possess antioxidant, anti-inflammatory, and antiangiogenic properties. Therefore, the aim of this study was to determine whether zinc, selenium, midkine (MK), interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-alpha (TNF-α), vascular endothelial growth factor-A (VEGF-A), platelet-derived growth factor-BB (PDGF-BB), and reduced glutathione (GSH) levels are associated with inflammation and angiogenesis processes in the context of a potential etiology causing aggravation of mitral regurgitation and/or ruptured chordae tendineae. Seventy-one subjects comprising 34 patients with mitral chordae tendineae rupture (MCTR) and 37 healthy controls diagnosed on the basis of their clinical profile and transthoracic echocardiography were included in this study. The levels of GSH, MK, selenium, and zinc were found to be lower in the patients group when compared to control group. There were no significant difference in plasma TNF-α, IL-1β, IL-6, IL-8, ...Continue Reading
