近日,发表在Circulation杂志上的一项研究表明,与华法林相比,直接口服抗凝剂(DOACs)在房颤(AF)患者中具有更好的疗效和安全性。

DOACs比华法林更适合用于AF患者的脑卒中预防。与研究级数据相比,使用个体患者数据的荟萃分析更具有显着优势。因此,相关研究人员使用来自COMBINE AF数据库的个体患者数据,该数据包括DOACs与华法林治疗AF的4项关键实验(RE-LY、ROCKET AF、ARISTOTLE、ENGAGEAF-TIMI 48)中随机分配的所有患者,通过荟萃分析的方式,使用分层Cox比例风险模型和随机效应模型比较标准剂量DOACs、低剂量DOACs和华法林在AF患者中的疗效。

研究共纳入71,683例患者(29,362例使用标准剂量DOAC;13,049例使用低剂量DOAC;29,272例使用华法林)。

结果显示,与华法林相比,标准剂量DOACs与卒中/全身性栓塞(883/29312[3.01%] vs. 1080/29229[3.69%];HR 0.81,95%CI 0.74-0.89)、死亡(2276/29312[7.76%] vs. 2460/29229[8.42%];HR 0.92,95%CI 0.87-0.97)、颅内出血(184/29270[0.63%] vs. 409/29187[1.40%];HR 0.45,95%CI 0.37-0.56)风险的显着降低相关,但大出血(1479/29270[5.05%] vs. 1733/29187[5.94%];HR 0.86,95%CI 0.74-1.01)风险无统计学差异。而低剂量DOACs与卒中/全身性栓塞(531/13049[3.96%] vs. 1080/29229[3.69%];HR 1.06,95%CI 0.95-1.19)风险无统计学差异,但颅内出血(55/12985[0.42%] vs. 409/29187[1.40%];HR 0.28,95%CI 0.21-0.37)、死亡(1082/13049[8.29%] vs. 2460/29229[8.42%];HR 0.90,95%CI 0.83-0.97)和大出血(564/12985[4.34%] vs. 1733/29187[5.94%];HR 0.63,95%CI 0.45-0.88)的风险更低。

对于卒中/全身性栓塞和死亡,标准剂量和低剂量DOAC与华法林的治疗效果在不同年龄和性别的患者中是一致的,而标准剂量DOAC在没有维生素K拮抗剂使用史和较低的肌酐清除率患者中更受青睐。

对于大出血,标准剂量DOAC更适合于体重较轻的患者(P=0.02)。在连续性协变量分析中,与华法林相比,年轻患者从标准剂量(P交互作用=0.02)和低剂量DOAC(P交互作用=0.01)中获益更大。
