INTRODUCTION. 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 aftereffects of heart disease on the central nervous system. OBJECTIVES. 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.
