| Ischemic Cardiomyopathy Nonischemic Cardiomyopathy Heart Failure | Drug: Ranolazine | Phase 3 |
There are limited treatment options for patients at high risk of ventricular arrhythmic events. Beta-blockers alone do not provide enough protection, sotalol has limited effectiveness, and amiodarone although effective in some groups of patients is used infrequently due to its side effects and limitations of a long-term use. Ischemia and cardiomyopathies are associated with a sodium overload of myocardial cells. Late sodium current plays a pivotal role in this process. Sodium overload leads to calcium overload of myocardial cells with consequent increased vulnerability of myocardium to ventricular tachyarrhythmias as well as increased impairment of diastolic relaxation of myocardium thereby augmenting the risk of ischemia and myocardial damage.
Ranolazine is a novel drug with anti-ischemic and antiarrhythmic properties that uniquely blocks late sodium current, decreases intracellular calcium overload, and improves diastolic relaxation of the ventricles. The antiischemic and antiarrhythmic properties of ranolazine might decrease the likelihood of arrhythmic events and improve the clinical course of patients with ventricular arrhythmias.
We designed a randomized double-blind placebo-controlled clinical trial enrolling 1,440 high-risk ICD patients who will be treated with ranolazine or placebo in addition to optimal medical therapy to test the hypothesis that late sodium current blockade contributes to significant reduction in the risk of arrhythmic events or death in high-risk ICD/cardiac resynchronization therapy-D patients.

Active Comparator: Ranolazine
At enrollment, patients will be randomized to ranolazine or placebo. In the active drug arm each patient will be started on a 500 mg twice a day dose for one week with subsequent increase to 1000 mg twice a day at end of first week. For patients on anti-arrhythmic therapy at the time of randomization, their ECG will be checked at end of first week on 500 mg dose and again at end of second week on 1000 mg dose. For patients with CrCl <60ml/min prior to randomization, their CrCl will be checked again at 2 weeks and study drug discontinued if <30ml/min. For patients with CrCl <60ml/min at 2 weeks, their CrCl will be checked again at 4 weeks and study drug discontinued if <30ml/min.
