Eligibility Criteria

Inclusion

  • Inclusion Criteria (Patients):
  • Stroke of likely cardioembolic cause or of undetected mechanism:
  • Lesions in at least one territory on MRI \& absence of significant large vessel disease defined as stenosis of cerebral or pre-cerebral vessels \>50% in arteries supplying the ischemic area(s) \& absence of severe small vessel disease including micro-bleeds on MRI.
  • Patients with central retinal artery occlusion documented by perimeter and absence of significant large vessel disease defined as stenosis of cerebral or pre-cerebral vessels \>50% \& absence of severe small vessel disease including micro-bleeds on MRI are included independent of acute MRI findings.
  • Large or small vessel stroke (atherosclerotic stroke):
  • Large vessel stroke: Acute lesions in one vascular territory on MRI, significant large vessel disease defined as stenosis of cerebral or pre-cerebral vessels \>50% leading to the infarcted territory \& absence of severe small vessel disease including micro-bleeds on MRI Small Vessel stroke: MRI documenting lacunar infarction, absence of significant large vessel disease defined as stenosis of cerebral or pre-cerebral vessels \>50% and presence of severe small vessel disease possibly including micro bleeds.
  • Ischemic stroke within 30 days prior to inclusion
  • Age \> 18 years
  • Life expectancy of at least one year
  • Informed consent
  • Stenosis: % defined by Ultrasound
  • Small vessel disease: defined according to STRIVE criteria
  • Inclusion Criteria (Controls)
  • 1\. Age and sex matched healthy controls. Matched with the group with stroke of likely cardioembolic stroke.
  • Exclusion Criteria (Patients):
  • Prior AF or AF \>30 sec on at least 6 hours of monitoring during hospitalization.
  • Other major cardio-embolic risk sources assumed as cause of stroke (e.g. endocarditis, myocardial infarction within last 4 weeks, prosthetic cardiac valve)
  • Contraindications to MRI (Including eGFR\<30 or other contraindications for the contrast agent used during Cardiac MRI)
  • Assumed unable to participate in the study by investigator (including but not restricted to psychiatric condition, dementia)
  • Exclusion Criteria (Controls):
  • History of stroke or AF
  • Contraindications to MRI (Including eGFR\<30 mL/min/1.73 m2 or other contraindications for the contrast agent used during Cardiac MRI)
