辛伐他汀对大鼠心肌梗死后交感神经重构和室性心律失常的影响
Effects of simvastatin on sympathetic remodeling and ventricular arrhythmias in rats with myocardial infarction
摘要
Abstract
Objective To investigate the effects of simvastatin on cardiac sympathetic remodeling and ventricular arrhythmias ( VA) in rats with myocardial infarction ( MI). Methods 48 SD rats were randomized to 3 groups; sham operation group (Group A), MI group (Group B), and simvastatin group (Group C). Immunohistochemistry was used to detect the distribution and density of growth associated protein-43 and tyrosine hydroxylase positive nerve in infarction border zone. Expressions of nerve growth factor, interleukin-ip, and tumor necrosis factor-a were detected by RT-PCR. Results As compared with those in Group A and C, the densities of positive nerve, targeted factors, and the incidence of VA were significantly higher in Group B (P < 0.05). Conclusion Simvastatin can prevent VA through improving sympathetic remodeling in rats with MI, the mechanism may be related to reducing inflammation and the expression of NGF. A关键词
