title: [Neurological complications in patients with heart disease].
abstract: BACKGROUND
  The brain needs a constant supply of oxygen and nutrients from blood. This fact explains its tight dependence on the cardiovascular system as well as the after effects of heart disease on the central nervous system.
  
  
  OBJECTIVE
  This study intends to describe the main conditions in which a neurological disorder appears secondarily to  or coincidentally with  heart disease. Methods. A bibliographical review of publications of neurological disorders related to heart disease is carried out.
  
  
  RESULTS
  The main cardiac diseases that can induce neurological disorders include: disturbances of the cardiac rhythm, congenital heart diseases, and complications of cardiac catheterisation and reparative surgery. Likewise, other conditions  congenital or acquired  in which neurological and heart disorders coexist must be considered.
  
  
  CONCLUSIONS
  Medical practice confirms that heart diseases account for different neurological conditions that can manifest by a very variable clinical expressivity.
