Effect of atrial septal dilation tumor and patent foramen rotundus on cryptogenic ischemic stroke in young and middle-aged patients.

Objective: To investigate the effect of atrial septal aneurysm (ASA) and patent foramen ovale (PFO) on cryptogenic ischemic stroke in young and middle-aged patients.

Methods: A case-control study was conducted to select 96 young and middle-aged patients with cryptogenic ischemic stroke in the Department of Neurology of our hospital from January 2015 to January 2020 (observation group). A total of 192 patients with non-ischemic stroke were selected as the control group. The clinicadata and transthoracic echocardiography (cTTE) results were compared between the two groups.

Results: The ASA depth and tumor wall thickness in the observation group were 15.50 (12.40, 19.80) mm and 3.90 (2.80,4.50) mm, respectively, which were significantly higher than those in the control group (P < 0.05). Logistic regression analysis showed that PFO, and PFO combined with ASA were the influencing factors of cryptogenic ischemic stroke in middle-aged and young people OR = 1.923 and 1.384, P < 0.05).

Conclusion: Atrial septal aneurysm combined with PFO and PFO are independent influencing factors factor for the occurrence of cryptogenic ischemic stroke in young and middle-aged people, which is worthy of further study.
