患有正常心脏节奏但体弱体弱收缩的病人面临很高的中风风险,这表明需要抗凝胶剂。 Patients with normal heart rhythms but weak atrial contraction face high stroke risk, suggesting need for anticoagulants.

美国心脏协会2025年科学会议上提出的一项新研究发现,患有氨酸氨酸心肌病 (ATTR-CM) 的人心律正常,但心房收缩不佳,而心房电力学解离 (AEMD) 则显著增加了中风风险,每年近9%的人患上中风或TIA. A new study presented at the American Heart Association's 2025 Scientific Sessions finds that people with transthyretin amyloid cardiomyopathy (ATTR-CM) who have normal heart rhythms but poor atrial contraction—measured by a condition called atrial electromechanical dissociation (AEMD)—face a significantly higher stroke risk, with nearly 9% experiencing a stroke or TIA annually. 这项研究基于2300多名患者的研究, 表明评估心房功能, 不仅仅是心律, 可以帮助识别高危人群, 即使没有心房动, 也可以从抗凝药等预防性治疗中受益. The research, based on over 2,300 patients, suggests that assessing atrial function, not just rhythm, could help identify high-risk individuals who may benefit from preventive treatments like anticoagulants, even without atrial fibrillation. 然而,该研究是观察性的,仅限于一个中心,而且所使用的诊断工具并不普遍。 However, the study is observational and limited to one center, and the diagnostic tool used is not widely available. 专家们呼吁进行规模更大、有前途的试验,以证实调查结果,并确定抗凝固是否降低这一组人的中风风险。 Experts call for larger, prospective trials to confirm the findings and determine if anticoagulation reduces stroke risk in this group.
