Abstract
BACKGROUND
This single-center observational study aimed to compare the echocardiographic and clinical features in patients diagnosed with migraine and embolic stroke of undetermined source (ESUS) who presented with a known patent foramen ovale (PFO).
METHODS
Two-dimensional and color Doppler images were obtained using various transthoracic echocardiography views for both migraine and ESUS patients. Suspected PFO cases underwent further assessment through contrast echocardiography and transesophageal echocardiography (TEE). High-risk PFO characteristics were evaluated using TEE, and the Risk of Paradoxical Embolism (RoPe) score was calculated.
RESULTS
The study included 310 participants (age range: 18-60, 73.2% female), with 43.5% diagnosed with migraine and 56.5% with ESUS. Common comorbidities included diabetes (26.1%). High-velocity shunting through the interatrial septum was observed in 35.5% of patients. ESUS patients were older, with higher rates of diabetes and hypertension, while active smoking was more prevalent among migraine patients. Basic echocardiographic parameters were mostly similar, except for elevated pulmonary artery systolic pressure in ESUS. ESUS patients exhibited a greater occurrence of large microbubble passage through the interatrial septum and longer PFO lengths compared to migraine patients. However, the RoPe and High-risk PFO scores were similar between the groups.
CONCLUSIONS
ESUS patients, characterized by older age and higher rates of diabetes and hypertension, demonstrated increased pulmonary artery pressure, more significant microbubble crossings, and longer PFO lengths. Conversely, migraine patients had a higher prevalence of active smoking. Despite differing clinical profiles, the risk scores for PFO-related embolic events were comparable between the groups. These findings underscore potential distinctions between ESUS and migraine patients with PFO and their implications for management strategies.
