Document Details : Title: Association of pentraxin- with the severity of rheumatic mitral valve stenosis Author(s): N. Polat , A. Yildiz , S. Alan , N. Toprak Journal: Acta Cardiologica Volume: 70 Issue: 4 Date: 2015 Pages: 409-413 DOI: 10.2143/AC.70.4.3094649 Abstract : Objectives: Inflammation is involved in the pathogenesis of rheumatic mitral valve stenosis (RMVS). Pentraxin-3 (PTX3) indicates the inflammatory state of humans. However, circulating PTX3 levels in patients with RMVS, remain largely unknown. In this study, we investigated whether there is an association between the severity of RMVS and PTX3. Methods: All patients diagnosed as rheumatic mitral valvular stenosis between December 2013 and April 2014 were included in the study. We investigated circulating PTX3 and high-sensitivity C-reactive protein (hsCRP) levels in patients with RMVS and healthy controls. Results: The study population included 72 subjects (41 patients with RMVS and 31 healthy subjects, 56 female) with a mean age of 40 ± 13 years. Patients with RMVS had higher left atrial diameters than healthy subjects. PTX3 and hsCRP were significantly higher in patients with RMVS when compared to control subjects and this difference was more significant in PTX3 compared to hsCRP (3.37 ± 1.11 vs 2.86 ± 0.59, P = 0.014 and 2.36 ± 1.48 vs 1.72 ± 0.73, P = 0.019, respectively). PTX3 was positively correlated with Wilkins score, mitral valvular area, mitral pressure gradient and left atrium diameter. Conclusions: We demonstrated that plasma PTX3 and hsCRP levels were increased in patients with RMVS. Compared to hsCRP, PTX3 was more closely related with the severity of mitral valve stenosis. These findings suggest that PTX3 may participate in the pathophysiology of RMVS. |
