目的 对于瓣膜病合并心房颤动的患者,同期进行AF的外科治疗,呈现逐步增加的趋势.尽管同期进行AF外科治疗,对窦性心律的恢复有很好的治疗效果.然而,该术式造成的副损伤也逐渐显现:如部分患者会出现左心房结构或功能的异常:如术后左心房收缩功能呈进行性下降、电—机械分离现象;左心房顺应性降低,术后出现肺动脉高压表现等.尽管临床上经超声心动图、CT、血流动力学等检查手段,可发现房颤手术后,左心房结构或功能的异常;然而AF手术后,左房壁的真实形态改变?目前,国内外还未见报道.

目的:研究氨酰tRNA合成酶基因多态性与先天性心脏病易感性是否有关.方法:本研究采用病例对照研究设计,选择CHD患者984例,非CHD健康对照2953例,检测MSC构成基因中的18个多态位点基因型及等位基因频率分布,进而比较不同多态位点基因型及等位基因与CHD易感性的关系.
背景 高同型半胱氨酸(Hey)是心脑血管疾病的重要危险因素,特别在亚洲人群当中伴有高同型半胱氨酸血症(HHcy)的高血压患者罹患脑卒中风险增加,体内叶酸水平的低下是引起高同型半胱氨酸的主要原因之一,但近年来我国高血压人群的叶酸水平尚无大样本研究揭示;体内叶酸与同型半胱氨酸的代谢循环复杂,受多因素影响,而叶酸、同型半胱氨酸、基因型之间的关系亟待证实.
