Heart‘omicsin’AGEing (HOMAGE):design,research objectives and characteristics of the common database

Heart failure is common in older people and its prevalence is increasing.The Heart ＇omics＇ in AGEing（HOMAGE） project aims to provide a biomarker approach that will improve the early diagnosis of heart failure.A large clinical database,based on（1） prospective population studies or（2） cross-sectional,prospective studies or randomized controlled trials（RCTs） of patients at risk for or with overt cardiovascular disease will be constructed to determine most promising ＇omics＇-based biomarkers to identify the risk of developing heart failure and/or comorbidities.Population studies,patient cohorts and RCTs are eligible for inclusion in the common database,if they received ethical approval to obtain and share data and have baseline information on cardiovascular risk factors.Currently,the HOMAGE database includes 43,065 subjects,from 20 studies in eight European countries,including healthy subjects from three population studies in France,Belgium and Italy（n = 7,124）,patients with heart failure（n = 4,312） from four cohorts in the UK,Spain and Switzerland and patients at high risk for cardiovascular disease（n = 31,629） in 13 cohorts.It is anticipated that more partners will join the consortium and enlarge the pooled data.This large merged database will be a useful resource with which to identify candidate biomarkers that play a role in the mechanism underlying the onset and progression of heart failure.

降压治疗与脑卒中二级预防:脑卒中后降压治疗研究

目的评价对于中国患者脑血管病后降压治疗是否可以预防脑卒中再发。方法采取双盲、安慰剂对照的试验方法,将患者随机分入对照组(n=2825)和干预组(吲达帕胺2.5 mg/d,n=2840)。一级终点事件为致死或非致死性再发脑卒中,二级终点事件为主要的致死或非致死心血管病事件。结果平均收缩压和舒张压分别为153.8和92.8 mm Hg。在随访中期(第2年),干预组收缩压/舒张压较对照组平均下降了6.8/3.3 mm Hg。干预组总共有159例再发脑卒中,对照组为219例(干预组HR=0.70;95%CI0.57～0.86;P<0.01)。干预组有199例发生心血管病事件,对照组为258例(HR=0.74;95%CI0.62～0.89;P=0.002)。结论吲达帕胺降压治疗可以降低中国人脑血管病患者再发脑卒中和心血管病事件。

正确解读高血压药物临床试验

时值循证医学年代,以心血管病事件为终点的高血压药物临床试验无疑为指导临床治疗和制定有关指南提供了不可或缺的证据,极大地推动了现代高血压诊治观念的变革。而且这一趋势方兴未艾,每年都有新的临床研究结果发布,几近成为了许多重要会议的压轴戏。随之而来的,就是对这些研究的讨论、解读、传播等。面对这一景象,冷静、客观、全面、公正地看待研究结果也越来越显得必要。
