Biovalve and meachanical valve replacement for valvular disease: the value of serum Apelin-12 detection / 中国组织工程研究

ABSTRACT

BACKGROUND:Artificial valve replacement for valvular disease has good biocompatibility and hemodynamic characteristics, but there are stil many factors that affect its therapeutic effects. OBJECTIVE:To detect the level of serum Apelin-12 in the perioperative period of valve replacement in valvular disease patients with atrial fibrilation. METHODS: Sixty-two patients with valvular heart disease scheduled for artificial valve replacement were selected, including 30 patients with persistent atrial fibrilation (atrial fibrilation group) and 32 patients with sinus rhythm (sinus rhythm group). There were 33 males and 29 females, with a mean age of (55±11) years. Levels of serum Apelin-12 and makers related to inflammation and oxidative stress were detected in two groups at admission. Furthermore, the sinus rhythm group was sub-divided into postoperative atrial fibrilation (POAF) group (n=8) and non-POAF group (n=24) after valve replacement, and the above-mentioned indicators were detected and compared between these two subgroups. RESULTS AND CONCLUSION:Compared with the sinus rhythm group, the serum level of Apelin-12 was significantly lower in the atrial fibrilation group, while the levels of high-sensitivity C-reactive protein and interleukin-6 and total antioxidant capacity were significantly higher in the atrial fibrilation group (P <0.05). Correlation analysis showed that the serum level of Apelin-12 was negatively correlated with high-sensitivity C-reactive protein level and total antioxidant capacity (r=-0.265,P=0.045;r=-0.960,P <0.001), but not correlated with the interleukin-6 level (r=-0.155,P=0.230). Compared with the non-POAF group, the serum level of Apelin-12 was significantly lower in the POAF group (P< 0.05), but the left atrial diameter, high-sensitivity C-reactive protein level were higher in the POAF group (P < 0.05). Apelin-12 may take part in the occurrence and maintenance of atrial fibrilation through the regulation of inflammations and oxidative stresses. The testing of serum Apelin-12 has a certain value in predicting the occurrence of postoperative atrial fibrilation.
