Impaired left ventricular systolic function (LVEF≤40% or at least moderately impaired)
You may not be if
1. Age \<18 or \>85;
2. Pregnancy;
3. Nursing home resident dependent on one or more activities of daily living;
4. Significant non-cardiac co-morbidity with high likelihood of death within 1 year (this would include any metastatic malignancy, or other terminal disease);
5. Significant psychiatric illnesses that may be aggravated by device implantation or that may preclude regular follow up;
6. Intravenous drug abuse (ongoing);
7. Unresolved infection associated with risk for hematogenous seeding;
9. Secondary prevention indication for an ICD (i.e. sustained ventricular arrhythmias occurring more than 48 hours after qualifying myocardial infarction (patients with ventricular arrhythmias occurring ≤48 hours of myocardial infarction, or with non-sustained ventricular tachycardia at any time, are not excluded));
10. On the heart transplant list;
11. Recurrent unstable angina despite revascularisation (defined as ongoing chest pain or ischemic symptoms at rest or with minimal exertion despite adequate treatment with anti-anginal medications);\*\*
12. Congestive heart failure New York Heart Association class IV, defined as shortness of breath at rest, which is refractory to medical treatment (not responding to treatment)\*\* \*\*NOTE: patients who meet exclusion based on (11) or (12) can be reviewed again in 2-3 days and if symptoms have resolved or treatment performed can be re-considered for inclusion.
