1Diagnostic and prognostic value of circulating micro RNAs in heart failure with preserved and reduced ejection fraction显示文摘micro RNAs(mi RNAs) are powerful regulators of posttranscriptional gene expression and play an important role in pathophysiological processes. Circulating mi RNAs can be quantified in body liquids and are promising biomarkers in numerous diseases. In cardiovascular disease mi RNAs have been proven to be reliable diagnostic biomarkers for different disease entities. In cardiac fibrosis(CF) and heart failure(HF) dysregulated circulating mi RNAs have been identified,indicating their promising applicability as diagnostic biomarkers. Some mi RNAs were successfully tested in risk stratification of HF implementing their potential use as prognostic biomarkers. In this respect mi RNAs might soon be implemented in diagnostic clinical routine. In the young field of mi RNA based research advances have been made in identifying mi RNAs as potential targets for the treatment of experimental CF and HF. Promising study results suggest their potential future application as therapeutic agents in treatment of cardiovascular disease. This article summarizes the current state of the various aspects of mi RNA research in the field of CF and HF with reduced ejection fraction as well as preserved ejection fraction. The review provides an overview of the application of circulating mi RNAs as biomarkers in CF and HF and current approaches to therapeutically utilize mi RNAs in this field of cardiovascular disease.Christian Schulte Dirk Westermann Stefan Blankenberg Tanja Zeller 2015World Journal of Cardiology2015,7,12:11
2急性心肌梗死合并急性肾损伤的危险因素分析显示文摘目的探讨急性心肌梗死(AMI)患者发生急性肾损伤(AKI)的危险因素。方法 AMI患者728例,分为AKI组和非AKI组。比较两组患者的临床资料,分析AMI患者发生AKI的独立危险因素,观察急诊冠状动脉介入治疗(PCI)对AMI患者发生AKI的影响。结果 728例AMI患者中发生AKI共152例(20.9%)。AKI组与非AKI组比较,年龄、糖尿病史、平均动脉压、收缩压、心率、心功能(Killip分级)、左心室射血分数、基础肾小球滤过率估计值、ST段抬高型心肌梗死、服用β-受体阻滞剂以及血管紧张素转换酶抑制剂/血管紧张素受体拮抗剂等指标差异具有统计学意义(P<0.01)。多因素Logistic分析显示,年龄、糖尿病史、入院收缩压、心功能分级、左心室射血分数、基础肾小球滤过率估计值、未服用血管紧张素转换酶抑制剂/血管紧张素受体拮抗剂是AMI患者发生AKI的独立危险因素。378例ST段抬高型心肌梗死,其中256例接受急诊PCI,统计分析显示未接受急诊PCI患者的AKI发生率显著高于急诊PCI患者(39.3%比19.5%,P<0.01)。结论 AKI是AMI常见的并发症,其发生与多种因素有关,急诊PCI能降低ST段抬高型心肌梗死患者AKI发生率。潘宏伟 郭莹 郑昭芬 彭建强 张宇 何晋 刘征宇 胡勇军 王长录 2015中国动脉硬化杂志2015,23,12:4
