Heterogeneity analysis of therapeutic efficacy and development of a prediction model for patent foramen ovale closure in the treatment of migraine with aura
摘要
Abstract
Objective:To investigate the differences in therapeutic efficacy of patent foramen ovale(PFO)closure for mi-graine with aura(MA)and develop a multidimensional prediction model integrating clinical,anatomical,and functional charac-teristics to optimize individualized treatment decisions.Methods:This prospective study enrolled 180 MA patients with transthoracic echocardiography(TEE)-confirmed PFO undergoing closure.At 1-year follow-up,patients were divided into an ef-fective group(n=138)and an ineffective group(n=42)based on≥50%reduction in headache impact test-6(HIT-6)and visual analog scale(VAS)scores.Preoperative clinical characteristics,anatomical parameters(PFO,PFO diameter,tunnel length,atrial septal aneurysm(ASA),eustachian valve(EV)/Chiari network(CN)),functional indicators(resting/Valsalva-induced right to left shunt(RLS)grade detection by conventional transthoracic echocardiography(TTE))were compared between groups.Independent predictors were identified through multivariate logistic regression to establish a PFO-migraine response score(PFO-MRS)model,with its discriminative performance validated by ROC curve analysis.Results:The overall effective rate was 76.67%(138/180).Significant intergroup differences(P<0.05)were observed in family history,TTE-detected PFO,PFO diameter>2 mm ASA,EV/CN,and resting RLS≥grade Ⅱ,multivariate regression confirmed these six factors as independent predictors of postoperative migraine improvement.The PFO-MRS model demonstrated 80.42%sensitivity and 73.84%specificity at a cutoff score≥5(AUC=0.813).Conclusion:PFO closure has a significant effect on MA patients with low genetic load(negative family history)and high anatomical-functional load(TTE-detected PFO+PFO>2 mm+ASA+EV/CN+resting RLS≥grade Ⅱ).The PFO-MRS model has shown initial ability to identify potentially beneficial populations.关键词
