Background, Motivation and Objective Accurate echocardiographic diagnosis of diastolic dysfunction is needed to guide heart failure treatment. Despite expected correlation between diastolic dysfunction and myocardial stiffness, only few studies have addressed shear waves to measure the myocardial stiffness non-invasively. We explore the naturally-occurring shear waves in the porcine septal wall caused by aortic and mitral valve closure with high frame rate recordings and subsequent shear wave imaging [Kanai, IEEE TUFFC 2005; Brekke et al., UMB 2014]. The aim is to estimate their propagation velocity.

进入21世纪以来,随着我国经济社会的飞速发展,我国城乡居民的工作节奏和生活方式都发生了很大变化,心脑血管疾病发生率呈现井喷趋势,并成为威胁我国人民健康的主要慢性疾病,心脑血管病导致的死亡已成为我国人群死亡的主要原因,而且其发病率和死亡率呈逐渐上升趋势,成为威胁人们健康的严重问题[1].无论是在亚洲还是欧美国家,心脑血管疾病也是排在首位的死亡因素.因此零级预防心脑血管疾病,成为当今医务工作者首要关注
目的 探讨社区空巢老人主观幸福感与社会支持、应对方式的关系。方法 以225名社区空巢老人为研究对象，采用纽芬兰纪念大学幸福度量表、领悟社会支持量表和特质应对方式问卷进行调查。结果 领悟社会支持总分及其各维度与主观幸福感呈正相关，积极应对与主观幸福感呈正相关，消极应对与主观幸福感呈负相关。积极应对和家庭内支持是主观幸福感的正向预测因子。结论 社会支持和应对方式是社区空巢老人主观幸福感重要的影响因素。
