Efficacy of interventional closure therapy on cryptogenic stroke with coexisting patent foramen ovale in young patients and its impact on serum fibrinogen and D-dimer levels

Abstract

Objective To explore the efficacy of interventional closure therapy in young patients with cryptogenic stroke and coexisting patent foramen ovale and analyze its impact on serum fibrinogen and D-dimer levels. Methods All subjects in this study were young stroke patients with PFO. After excluding patients who did not meet the inclusion criteria, they were registered and divided into two groups based on the treatment method: the closure group and the medical group. Results There were no significant differences in basic clinical data between the two groups, indicating comparability (p > 0.05). The closure group showed better heart function after treatment compared to the medical group, with significant differences (p < 0.05). Headache symptoms in the closure group were less severe than those in the medical group after treatment, with significant differences (p < 0.05). Laboratory indicators in the closure group were better than those in the medical group after treatment, with significant differences (p < 0.05). Serum fibrinogen and D-dimer levels in the closure group were lower than those in the medical group after treatment, with significant differences (p < 0.05). Conclusion Interventional closure therapy demonstrated positive effects on young patients with cryptogenic stroke and coexisting PFO, showing improvements in heart function, headache symptoms, and blood coagulation parameters. While the study suggests potential benefits, cautious interpretation is warranted, given the observational study design. Further research with a larger sample size and long-term follow-up is needed to validate these findings.
