Heart clots leave unique brain marks after stroke
NCT ID NCT04456309
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at brain MRI scans of 122 stroke patients to see if those with a blood clot in the heart (intracardiac thrombus) had different patterns of brain damage compared to those with atrial fibrillation. Researchers analyzed the location, size, and number of stroke lesions. The goal was to better understand how these conditions cause strokes, which may help guide future diagnosis and treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * consecutive patients presenting with acute symptomatic cardioembolic infarction associated with ICT, recruited and registered in the stroke database between June 2018 and November 2019 of our centre (Nîmes University Hospital, France). These patients were compared with consecutive cardioembolic stroke patients with known or newly discovered AF (in the absence of ICT on echocardiography), recruited during the same time period. * Brain MRI (including diffusion-weighted imaging \[DWI\]) performed within one week of symptom onset; complete etiological work-up including intracranial (time-of-flight \[TOF\], gadolinium-enhanced magnetic resonance angiography \[MRA\], or computed tomographic angiography \[CTA\]) and extracranial (gadolinium-enhanced MRA, CTA, or duplex ultrasound) vessel imaging; transthoracic or transoesophageal echocardiography; and ≥24h ECG monitoring (acute stroke unit monitoring and/or Holter ECG monitoring). Exclusion Criteria: * opt-out patient
