Section III. CARDIOVASCULAR DISORDERS

1-21. CORONARY ARTERY DISEASE

Coronary artery disease (CAD) is the condition in which the coronary arteries cannot deliver adequate blood supply to the heart muscle to meet the tissue demand. This condition is characterized by obstruction or narrowing of the vessel lumen. Coronary artery disease has been linked with certain "risk factors." In general, the more risk factors associated with an individual, the greater the chance for development of CAD. Some risk factors cannot be changed, while other risk factors can be modified or eliminated. Patient education is an important aspect of the nursing care of patients with CAD because the educated patient can take steps to improve his condition.
