JACC:低剂量替卡格雷有降低心梗患者出血发生的趋势

2017-09-08 MedSci MedSci原创

替卡格雷(Ticagrelor)可以降低心梗(MI)患者缺血的风险,但是长期的P2Y12抑制剂治疗收益与缺血发生风险之间的平衡尚未阐明。本研究纳入了PEGASUS-TIMI54临床试验的21162名患者,并将其随机分成替卡格雷90mg组、替卡格雷60mg组或安慰剂组,并对其心源性死亡事件、心梗、卒中和主要出血事件进行评估。经过平均33个月的随访,心源性死亡事件、心梗、卒中在安慰剂组中的发生频率很稳

替卡格雷(Ticagrelor)可以降低心梗(MI)患者缺血的风险,但是长期的P2Y12抑制剂治疗收益与缺血发生风险之间的平衡尚未阐明。

本研究纳入了PEGASUS-TIMI54临床试验的21162名患者,并将其随机分成替卡格雷90mg组、替卡格雷60mg组或安慰剂组,并对其心源性死亡事件、心梗、卒中和主要出血事件进行评估。经过平均33个月的随访,心源性死亡事件、心梗、卒中在安慰剂组中的发生频率很稳定,年发生率约3%,替卡格雷60mg组的获益在每个亚组中也是一致的(1年的HR:0.82;95% [CI]: 0.67 - 0.99; 2 年的HR: 0.90; 95% CI: 0.74 - 1.11; 3年的HR: 0.79; 95% CI: 0.62 - 1.00)。此外,主要出血事件在替卡格雷60mg每个亚组中均有升高,尤其是在第一年(第一年 HR: 3.22;第二年 HR: 2.07; 第三年 HR: 1.65)。

研究结果表明,心梗患者的5年心源性死亡事件、心梗和卒中的发生风险依旧较高,长期服用低剂量的替卡格雷有降低出血发生的趋势。

Eur Heart J:走路慢的中年人心血管疾病以及全因死亡风险更大

近日,来自英国国立卫生研究所,莱斯特生物医学研究中心久坐行为与健康领域专家 Tom Yates 教授的团队在心血管疾病顶级期刊《欧洲心脏杂志》上发表的一项研究表明,走路慢的中年人全因死亡风险以及心血管疾病死亡风险是走路快的近两倍。而且,这一发现已经排除了性别,吸烟,BMI,饮食或观看电视时间等心血管疾病相关危险因素。

JACC:氯沙坦能明显改善心梗后二尖瓣纤维化

心肌梗塞后,拘束着的二尖瓣会刺激瓣膜小叶适应性的增生,瓣膜的增厚和纤维的增生反而会加重二尖瓣反流,从而导致心衰甚至死亡。心梗后的二尖瓣纤维增生与过度的上皮-间充质转化(EMT)相关,由TGF-β过表达引起。既往的体外实验证实氯沙坦介导的TGF-β抑制作用可以减少二尖瓣的EMT过程。本研究将17只山羊分成两组,一组是假手术对照组(n=6),另一组(n=11)通过心梗造模引起二尖瓣乳头肌缩短,从而导致

JACC:硝普钠可以改善重度主动脉瓣狭窄患者的血流动力学水平

低梯度的重度主动脉瓣狭窄(LGSAS)伴保留型射血分数的病理机制尚未阐明,近日,在国际心血管权威杂志JACC上发表了一篇旨在硝普钠对LGSAS伴保留型射血分数患者的急性血流动力学影响的研究。本研究纳入了41例有临床症状的LGSAS伴保留型射血分数的患者(25例低血流[LF],SVI≤35 ml/m2;16例血流正常[NF]),并在接受硝普钠治疗前后对其血流动力学水平进行评估。在随访开始时,LF患者

JACC-Cardiovasc imag:冠状动脉钙化是确定心血管疾病早期风险的“风向标”

近些年来,心血管疾病不断增加,由于突发性心血管疾病死亡的人数也不再少数。近期,来自美国的研究人员找到了预测心血管疾病风险的重要指标。近日发表于《JACC:心血管成像》杂志上的文章指出,心血管疾病的最佳指标,那就是冠状动脉钙化情况。冠状动脉钙化通常被视为一种“不良”的现象,其严重程度直接影响了疾病的预后效果。

JACC:中枢性睡眠呼吸暂停与心衰不良预后呈相关性!

既往大型临床试验表明,无创机械通气治疗收缩型心衰患者的中枢性睡眠呼吸暂停(CA)的效果较差。近日,在国际心血管权威杂志JACC上发表了一篇旨在评估收缩型心衰患者的白天、晚上和24h的CA发生率和预后情况的临床研究。本研究纳入了正在接受指南指导下治疗的525名心衰患者(左室射血分数[LVEF] of 33 ± 9%;年龄66±12岁;男性占77%),主要终点事件是心源性死亡。最终随访结果表明,24h

JACC:糖尿病会明显影响房颤患者预后!

糖尿病是房颤患者发生血栓栓塞的风险因素,然而,糖尿病对房颤患者预后结局的影响尚未阐明。近日,在国际心血管权威杂志JACC上发表了一篇旨在评估比较伴有或不伴有糖尿病的房颤患者的临床特征、健康状态和预后差异的临床研究。本研究纳入了ORBIT-AF注册数据库中的9749名房颤患者,终点事件包括患者的临床特征、健康状态、房颤治疗管理、2年死亡率、住院率、血栓栓塞事件、心衰和房颤进展。最终结果表明,伴有糖尿
