Effects of patent foramen ovale in migraine: a metabolomics-based study.

ABSTRACT: Patent foramen ovale (PFO), a cardiac anatomical anomaly inducing abnormal haemodynamics, leads to a paradoxical bypass of the pulmonary circulation. PFO closure might alleviate migraines; however, clinical evidence and basic experiments for the relationship are lacking. To explore the effect of PFO on migraine, 371 migraineurs finishing blood tests and contrast transthoracic echocardiography for the detection of PFO were prospectively included. Multivariate regression analysis revealed that PFO was independently associated with aura, and lower cystatin-C (cys-C) and calcium levels. Among them, patients with PFO who underwent percutaneous PFO closure were continuously followed up 1 year after the operation. The intensity of migraine was significantly relieved and the levels of cys-C and ca
