Dual antithrombotic therapy (DAT) with low-dose rivaroxaban in combination with acetylsalicylic acid (ASA) is available to patients with stable atherosclerotic disease as a new therapeutic option.The results of the COMPASS trial demonstrate a significant relative risk reduction of cardiovascular outcomes by 24 % with low-dose DAT in patients with stable peripheral arterial disease or coronary heart disease.Despite a guideline adherent secondary prevention therapy, the cardiovascular event rate with ASA alone during the mean study period of almost two years was 5.4 %. The absolute reduction of the event rate by the low-dose DAT is low at 1.3 %. Consequently, it is important to identify groups of patients at high risk for cardiovascular events. These patients are particularly qualified to receive a DAT regimen and can be characterized using high-risk features.The individual ischemic risk profile may be further defined by the presence of polyvascular atherosclerosis, concomitant diseases, and ischemic events in the past. The quo ad vitam reduced prognosis of patients with polyvascular atherosclerosis advocates a polyvascular screening, even in supposedly stable patients with coronary heart disease and peripheral arterial disease.An intensification of antithrombotic therapy is naturally associated with an increased risk of bleeding. Therefore, the risk-reduction of ischemic events should be weighed individually against the risk of bleeding.A low-dose DAT is particularly suitable for patients with a high ischemic risk and a low risk of bleeding.
对于患有稳定型动脉粥样硬化疾病的患者,低剂量利伐沙班联合乙酰水杨酸(ASA)的双重抗栓治疗(DAT)是一种新的治疗选择。COMPASS试验结果表明,在患有稳定型外周动脉疾病或冠心病的患者中,低剂量DAT可使心血管结局的相对风险显著降低24%。尽管采用了符合指南的二级预防治疗,但在近两年的平均研究期间,仅使用ASA时心血管事件发生率为5.4%。低剂量DAT使事件发生率的绝对降低幅度较小,为1.3%。因此,识别心血管事件高危患者群体很重要。这些患者特别适合接受DAT方案,可通过高危特征进行特征描述。个体缺血风险概况可通过多血管动脉粥样硬化、合并疾病以及过去的缺血事件进一步确定。多血管动脉粥样硬化患者生活质量下降的预后情况提倡进行多血管筛查,即使是在看似稳定的冠心病和外周动脉疾病患者中。抗栓治疗的强化自然会增加出血风险。因此,应根据个体情况权衡缺血事件风险降低与出血风险。低剂量DAT特别适合缺血风险高且出血风险低的患者。
