JACC:经导管二尖瓣修复患者房颤的患病率以及对1年预后的影响

2019-03-24 xiangting MedSci原创

接受经导管MV修复的患者中AF很常见,并与1年的临床结局较差相关。

这项研究目的是比较伴和不伴房颤(AF)患者经导管二尖瓣(MV)修复后的1年结局。

退行性二尖瓣返流(MR)患者出现AF被认为是MR进展的标志,并与不良临床事件相关。然而,AF对经导管MV修复患者的影响仍不确定。

使用TVT登记(经导管瓣膜治疗)查找2013年11月至2016年6月期间使用MitraClip进行经导管MV修复的患者。使用医疗保险和医疗补助服务中心相关数据,比较伴和不伴AF患者经导管MV修复后的1年死亡率、心衰住院率、中风和出血率。使用多因素Cox回归建模分析结局。

研究期间,共有5,613名患者在美国接受了商业经导管MV修复,其中3,555名患者(63%)预先存在房颤。与无AF患者相比,AF患者的年龄更大,男性和高加索人的可能性更高,合并症更多,胸外科医师学会预测死亡风险评分更高(中位数7%vs.5%; p<0.0001)。急性手术成功率(手术后≥2+ MR,37.4%vs.35.0%; p=0.20)和院内死亡率相似,但AF患者的住院时间更长(平均4.91天vs.4.37天; p=0.0004)。共有3,261名患者与医疗保险和医疗补助服务中心索赔数据相关联。调整后,AF患者的1年死亡率或HF率较高(风险比[HR]:1.27; 95%置信区间[CI]:1.11-1.44; p<0.001)。AF患者的1年死亡率(HR:1.44; 95%CI:1.22-1.70; p<0.001)、HF住院率(HR:1.17; 95%CI:1.00-1.36; p=0.05)、中风率(HR:1.63; 95%CI:1.01-2.64; p=0.047)和出血率较高(HR:1.34; 95%CI:1.10-1.64; p=0.004)。AF患者中,抗凝患者的中风风险较低(HR:0.55; 95%CI:0.32-0.93; p=0.026)。

尽管急性手术成功率相似,接受经导管MV修复的患者中AF很常见,并与1年的临床结局较差相关。需要进一步的研究以探讨MR的早期治疗是否会降低未来发生房颤的风险,并确定可以改善这些患者预后的疗法。

JACC:直接口服抗凝药物对二尖瓣狭窄患者的影响

对于二尖瓣狭窄和房颤患者,需要服用抗凝药物以预防卒中的发生,到目前为止,所有研究直接口服抗凝药物(DOACs)的研究均排除了中重度二尖瓣狭窄患者。本研究的目的旨在评估DOACs对二尖瓣狭窄患者的疗效影响。本研究纳入了2230名二尖瓣狭窄和房颤患者(平均年龄为69.7±10.5岁,男性占30.6%),主要终点事件是缺血性卒中或系统性血栓的发生。结果显示,血栓栓塞事件的发生率在DOAC组中为2.22%

JACC:房颤患者认知功能的降低与亚临床脑损伤相关

房颤患者发生认知功能下降的风险更高,可能是由未知的脑血管损伤引起。本研究的目的旨在评估房颤患者的认知功能和脑血管损伤的相关性。本研究纳入了1737名房颤患者,平均年龄为73 ± 8 岁,女性占28%,90%接受有口服抗凝药物治疗。经过头颅磁共振检查,发现387名(22%)患者有大的非皮质或皮质梗塞(LNCCIs),368名(21%)患者有皮质下小梗死(SNCIs),372名(22%)患者有微出血,

Chest:短暂睡眠时间与房颤的关系

由此可见,较短的睡眠持续时间与房颤患病和发病独立相关。需要进一步研究以确定延长睡眠的干预是否可以降低房颤风险。

大连医大二院研究称,三成高血压住院患者合并房颤,控制血压有助于预防房颤

JACC:极低体重房颤患者的抗凝治疗——DOACs vs 华法林

目前,对于非瓣膜性房颤(AF)和极低体重(50kg)患者,直接口服抗凝药物(DOACs)的有效性和安全性尚不清楚。本研究的目的旨在评估和比较DOACs和华法林对极低体重AF患者的效果。本研究纳入了韩国国家数据库中的接受口服抗凝药物治疗的体重≤60kg的AF患者(DOACs n=14013;华法林 n=7576),并用倾向性评分调整两组患者。分析结果显示,与华法林相比,DOACs 与更低的缺血性卒中
