Neurologic complications of cardiovascular diseases.

Neurocardiology considers the interrelationships between the circulatory and nervous systems. An appreciation of the anatomic relationship preceded the concept of the clinical relationship of the two systems. Epidemiologic studies link risk factors of the cardiovascular and nervous systems. Neurologic signs and symptoms are often the presenting indication of cardiovascular disease. Neurologic complications occur during the natural history of cardiovascular disease, during diagnostic evaluation, and in the treatment process. A knowledge of potential complications as well as their frequency will help the physician make ethical and valid recommendations to patients concerning their management. This article highlights some of the potential complications that may be encountered in the management of patients with cardiovascular diseases.
