BACKGROUND Safe and effective pharmacologic therapy for atrial fibrillation (AF) in heart failure (HF) is an unmet need. In AF clinical trials, the standard primary endpoint of time to first symptomatic AF event (TTFSE) has several disadvantages, which could theoretically be overcome by measurement of AF-specific symptoms burden during an entire follow-up period. OBJECTIVES The authors sought to develop and validate a method of measuring symptom burden of AF in a HF population. METHODS The authors constructed a patient-reported outcome instrument (Atrial Fibrillation Symptoms Questionnaire [AFSQ]) to function in the setting of AF/HF, and used it to measure symptoms throughout long-term follow-up. The AFSQ queries the presence of 10 new or worsening symptoms, equally divided between those associated with AF or HF. In a 267 patient AF/HF trial comparing 2 AF prevention treatments, the AFSQ was linked to electrocardiography documented AF to form a 2-component clinical outcome assessment (SxBAF) that was subjected to psychometric testing, anchor validation, and endpoint efficiency comparison to TTFSE. RESULTS SxBAF exhibited greater efficiency than time to first symptomatic event for treatment difference detection, resulting in smaller projected clinical trial sample sizes. SxBAF correlated well with device-detected AF burden (Spearman's ρ = 0.74; P < 0.0001), while permitting gradation in symptom severity. SxBAF also identified treatment group differences in cardiovascular serious adverse events and AF interventions and in recent-onset AF provided specificity for AF- or worsening HF-associated symptoms (P < 0.001 for each). CONCLUSIONS Measurement of symptoms burden throughout clinical trial follow-up is feasible in AF/HF and should be useful for evaluating patient-centered outcomes in AF prevention trials.

症状负担作为心房颤动心力衰竭患者的临床结果评估。



背景 心力衰竭 (HF) 患者心房颤动 (AF) 的安全有效药物治疗是一项未满足的需求。在 AF 临床试验中,首次症状性 AF 事件时间 (TTFSE) 的标准主要终点有几个缺点,理论上可以通过在整个随访期间测量 AF 特异性症状负担来克服这些缺点。目的 作者试图开发和验证一种测量 HF 人群 AF 症状负担的方法。方法 作者构建了一个患者报告的结果工具 (Atrial Fibrillation Symptoms Questionnaire [AFSQ]),在 AF/HF 的情况下发挥作用,并使用它来测量整个长期随访中的症状。AFSQ 查询是否存在 10 种新的或恶化的症状,与 AF 或 HF 相关的症状平均分配。在一项比较 2 种 AF 预防治疗的 267 名患者的 AF/HF 试验中,AFSQ 与心电图记录的 AF 相关联,形成 2 分量临床结果评估 (SxBAF),该评估接受心理测试、锚验证和终点效率与 TTFSE 的比较。结果 SxBAF 在治疗差异检测方面表现出比首次症状事件的时间更高的效率,导致预计临床试验样本量更小。SxBAF 与设备检测到的 AF 负荷密切相关 (Spearman 的 ρ = 0.74;P < 0.0001),同时允许症状严重程度的分级。SxBAF 还确定了治疗组在心血管严重不良事件和 AF 干预方面的差异,以及近期发作的 AF 为 AF 或恶化的 HF 相关症状提供了特异性 (P < 0.001)。 结论 在整个临床试验随访过程中测量症状负担在 AF/HF 中是可行的,并且应该有助于评估 AF 预防试验中以患者为中心的结果。(预防心力衰竭患者症状性心房颤动的基因靶向治疗 [GENETIC-AF];NCT01970501)。
