Atrial Septal Aneurysm may Cause In-Hospital Recurrence of Cryptogenic Stroke.
Abstract
Awareness of potentially embologenic diseases is critical to determining the prognosis of cryptogenic stroke. The clinical significance of atrial septal aneurysm (ASA) in cryptogenic stroke has not been fully studied. Therefore, we explored clinical characteristics and in-hospital recurrence in patients with ASA in cryptogenic stroke. A multicenter observational registry of cryptogenic stroke patients was conducted. We obtained baseline characteristics, radiological and laboratory findings, and echocardiographic findings, especially of embolic sources on transesophageal echocardiography. The CHALLENGE ESUS/CS (Mechanisms of Embolic Stroke Clarified by Transesophageal Echocardiography for embolic stroke of undetermined source/cryptogenic stroke) registry was recorded at http://www.umin.ac.jp/ctr/ (UMIN000032957). Patients' clinical characteristics were compared according to the presence of ASA, and factors associated with in-hospital stroke recurrence were assessed. The study included 671 patients (age, 68.7±12.7 years; 450 males; median National Institutes of Health Stroke Scale score, 2). ASA was detected in 92 patients (14%), displaying higher age (72.4±11.0 vs. 68.1 ±12.9 years, p=0.004), reduced frequency of diabetes mellit...Continue Reading
