Atrial fibrillation and venous thromboembolism (VTE) are common disorders associated with maleficent thrombotic events, particularly in the elderly patients. Polypharmacy, co-morbidities, and altered pharmacokinetics, often present in these patients, render the use of anticoagulants quite challenging. Novel oral anticoagulants (NOACs) have recently emerged as alternatives to Vitamin K Antagonists (VKAs) and are gradually increasing their popularity mainly because of their fewer drug and food interactions and ease of use. Their effectiveness and safety has been well-established in the general population but the balance between benefit and harm in the elderly is still unclear. Routine use in these patients is uncommon. Accumulating data have shown that the benefit of NOACs is consistent among all age groups, featuring equal or greater efficacy in preventing thrombotic events. Excess bleedings were lower with NOACs in comparison to VKAs, but bleeding patterns were disparate among them and head to head comparison is not available. The present review highlights on the efficacy and safety of novel anticoagulants in the elderly population.
心房颤动和静脉血栓栓塞(VTE)是与不良血栓形成事件相关的常见疾病,尤其是在老年患者中。这些患者常存在多种药物联用、合并症以及药代动力学改变的情况,使得抗凝剂的使用颇具挑战性。新型口服抗凝剂(NOACs)最近已成为维生素K拮抗剂(VKAs)的替代药物,并且由于其较少的药物和食物相互作用以及使用便捷性,其受欢迎程度正在逐渐提高。它们在普通人群中的有效性和安全性已得到充分证实,但在老年人中利弊之间的平衡仍不明确。在这些患者中常规使用并不常见。越来越多的数据表明,NOACs在所有年龄组中的益处是一致的,在预防血栓形成事件方面具有同等或更高的疗效。与VKAs相比,NOACs导致的出血过多情况较少,但它们之间的出血模式不同,且缺乏直接对比。本综述重点关注新型抗凝剂在老年人群中的疗效和安全性。
