Ranolazine in Ischemic Cardiomyopathy

Ranolazine in Ischemic Cardiomyopathy Patients With Persistent Chest Pain or Dyspnea Despite Conventional Therapy: A Cross-Over Study

Patients with ischemic cardiomyopathy may continue to experience persistent chest pain and shortness of breath despite conventional medical therapy and/or revascularization. The purpose of this study is to determine the efficacy of taking Ranexa versus placebo in patients with ischemic (due to blockages) cardiomyopathy treated with optimal conventional medical therapy and/or percutaneous revascularization.

Inclusion Criteria:

1. Ischemic cardiomyopathy patients on optimal medical treatment. Optimal medical treatment is defined as the continued symptoms of chest pain or dyspnea despite treatment with 2 antiischemic agents (beta blockers, CCB or nitrates). Unless contraindicated, all cardiomyopathy patients should be treated with a beta blocker and an ACEI/ARB.
2. Anginal chest pain or dyspnea
3. Documentation of non treatable or optimally treated coronary artery disease
4. Ejection Fraction of less than or equal to 40%

Exclusion Criteria:

1. Less than 18 years of age
2. Pregnant or breast feeding
3. Patients with non ischemic cardiomyopathy
