Sudden cardiac arrest is a possible cause of death in patients with non-ischemic cardiac muscle weakness, i.e. a type of heart failure caused by genetics or for which no cause is known. Now, researchers have successfully demonstrated the advantages of an implanted defibrillator (ICD) as a means of prevention in patients with moderately restricted cardiac function, and that patients with the condition must be treated as carefully as patients with ischemic heart failure which has developed following a heart attack, for example.
