All heart patients should know the pumping status of their heart, which is called ejection fraction. If low these patients are at risk of sudden cardiac death during winter season, said Padma Shri & Dr. B.C. Roy National Awardee, Dr. KK Aggarwal, President, Heart Care Foundation of India.
The guidelines from American College of Cardiology and American Heart Association for device-based therapy of cardiac rhythm abnormalities suggest that an internal electric shock devise called an ICD therapy is indicated in all patients with heart functioning called LVEF of less than 35% due to prior heart attack (post 40 days) and who are symptomatic.
The guidelines further suggest that ICD therapy is indicated in patients with non-ischemic dilated cardiomyopathy (enlarged heart) who have an LVEF less than or equal to 35% and who are symptomatic.
ICD therapy is also indicated in patients with heart dysfunction due to prior heart attack who are at least 40 days post heart attack with LVEF less than 30% even if they have no symptoms.
ICD therapy is also indicated in patients post heart attack with LVEF less than 40% if they have irregular heart abnormality of non-sustained VT (Ventricular Tachycardia) on 24 hour ECG monitoring or inducible abnormal heart rhythm called VF (Ventricular fibrillation) or sustained VT at electrophysiological study.
