Cardioembolic stroke.

Abstract

Approximately 15% of ischemic strokes are the result of an embolism from a cardiac source. Patients with nonvalvular atrial fibrillation, acute myocardial infarction, ventricular aneurysm, rheumatic heart disease, prosthetic heart valves and other less common cardiac disorders are at an increased risk for cardioembolic stroke. Clinicians must distinguish cardioembolic from atherosclerotic strokes to provide unique management for each patient. The nurse plays a dynamic role in diagnosis, education and treatment of patients at risk or who have had a stroke from a cardiac source. Knowledge of the pathophysiologic mechanisms and treatment options is essential for the nurse to adequately manage patient care.
