    前瞻性研究235名INVOR(福拉尔贝格透析患者事件研究)的透析患者,对其进行长达7年的随访,分析心房颤动(AF)的患病率和发病率以及香豆素治疗对生存的影响。       一共748患者年,中位随访 时间为2.84年。 12例(5.1%)在透析开始即患有房颤(AF)。随访期间,40例(17.0%)逐渐发展为AF,代表年发病率为5.85%。 AF与死亡率呈正相关(p = 0.004)。235例患者中的46名(19.6%)给予香豆素治疗。多数(93.7%)有口服抗凝剂的迹象。 在65%的患者中,使用香豆素治疗AF的指征是明确的。 不使用香豆素和无AF患者被作为对照组。香豆素组和香豆素替代物组的死亡风险略低于对照组 [风险比(HR)的95%可信区间(CI)和P值分别为:0.80(0.28-2.29),P = 0.679; 0.42(0.16-1.10),P = 0.078]。 口服足量抗凝剂情况下,无一例患者出现中风或致命的出血事件。与对照组相比,有使用香豆素禁忌的AF患者的死亡风险显著升高 [HR(95%CI):3.90(2.16-7.04),P <0.001]。       所以我们的数据表明,如果有明确的使用指征且在使用过程中密切监测,使用香豆素可能比预想中的风险要小。
