Cardiac disorders like atrial fibrillation are key causes of stroke due to thrombus formation. Advanced diagnostics and new therapies are improving the prevention of cardioembolic events.

Area of Science:

  • Cardiology
  • Neurology
  • Vascular Medicine

Background:

  • The heart is a primary site for thrombus formation, leading to cardioembolic stroke.
  • Several cardiac conditions, including atrial fibrillation and valvular heart disease, elevate the risk of cardioembolism.

Purpose of the Study:

  • To review cardiac factors contributing to cardioembolic stroke.
  • To discuss current and emerging diagnostic and therapeutic strategies for preventing cardiac thrombus and embolism.

Main Methods:

  • Review of literature on cardiac causes of stroke.
  • Discussion of diagnostic tools such as transesophageal echocardiography (TEE) and intravascular ultrasound.
  • Exploration of current and novel preventive therapies.

Main Results:

  • Atrial fibrillation, left ventricular dysfunction, valvular heart disease, and structural abnormalities are major cardiac sources of emboli.
  • Transesophageal echocardiography (TEE) enhances the identification of cardiac sources.
  • Embolus detection monitoring and intravascular ultrasound offer potential for objective assessment and evaluation.

Conclusions:

  • Understanding the heart-brain relationship is crucial for stroke prevention.
  • New diagnostic methods and therapeutic approaches are vital for managing cardiac thrombus and reducing cardioembolic events.
  • Further research into the heart-brain axis will significantly impact future clinical practice.
