Start Activity

Target Audience and Goal Statement

This activity is intended for heart failure specialists, interventional cardiologists, electrophysiologists, general cardiologists, cardiac nurses, and other healthcare professionals involved in the care of patients at risk for sudden cardiac arrest.

The goal of this activity is to improve the understanding of management options for the primary prevention of sudden cardiac death in patients diagnosed with nonischemic cardiomyopathy.

Upon completion of this activity, participants will be able to:

Describe the importance of using ejection fraction in identifying the risk of sudden cardiac death in patients with nonischemic cardiomyopathy
Discuss treatment options for patients with nonischemic cardiomyopathy at risk for sudden cardiac death

Managing the Risk of Sudden Cardiac Death in Nonischemic Patients

Considerable controversy exists regarding the implantation of an internal cardioverter-defibrillator in patients who are considered high risk, but do not fulfill current guidelines for receiving such a device. This is clearly the case with patients diagnosed with nonischemic cardiomyopathy who have left ventricular dysfunction. During the waiting period to determine if there is improvement in ventricular function, the patient is vulnerable to ventricular ectopy and sudden cardiac death. Drs John Chin and Owen Obel discuss how the wearable cardioverter-defibrillator can get patients through this critical period.
