The characteristics and prognosis of patients with first-detected atrial fibrillation (AF) in Japan remain unclear.
First-detected AF patients without structural heart disease (n=289) were reviewed with regard to 2 symptom classifications (CCS-SAF and EHRA). In both classifications, asymptomatic patients comprised ≈40% of the patients, and patients in the most symptomatic class (≈6%) had peculiar characteristics and poor prognosis. In other symptomatic classes, symptoms affected the treatment strategy without a significant difference in the patients' backgrounds and prognosis.
This is the first report to describe the distribution, characteristics and outcomes of first-detected AF patients according to symptom classifications.
日本首次发现的心房颤动（AF）患者的特征和预后仍不清楚。
对无结构性心脏病的首次发现的 AF 患者（n=289）进行了回顾，涉及 2 种症状分类（CCS-SAF 和 EHRA）。在这两种分类中，无症状患者约占患者的 40%，而症状最严重的患者（约 6%）具有独特的特征和较差的预后。在其他有症状的类别中，症状影响治疗策略，但患者的背景和预后没有显著差异。
这是第一份根据症状分类描述首次发现的 AF 患者分布、特征和结局的报告。
