Ranolazine in Ischemic Cardiomyopathy
Study Details
Study Description
Brief Summary
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.

Outcome Measures
Primary Outcome Measures
- Anginal Frequency [12 weeks]
Anginal frequency as assessed by Seattle Angina Questionnaire. Scoring is done by assessing responses on an ordinal value. Anginal score is scored by the patient by selecting a number from 0 to 100 with low score indicates more anginal frequency. The mean of the the scores of all patients analyzed were compared between placebo and Ranolazine.
- Quality of Life [12 weeks]
Quality of life as measured by the Seattle Angina Questionnaire as a score ranging from 0 to 100. Higher score indicates better quality of life. The Qaulity of life is scored by the patient. It assesses the perceived satisfaction or dissatisfaction in the major domains of life. These include mobility, self-care, Usual activities (leisure, work, family), Pain/Discomfort, and Anxiety.
- Dyspnea Assessed by the Rose Dyspnea Questionnaire (RDQ) [12 weeks]
RDQ is a four item questionnaire that evaluates a patient's dyspnea with regular activity. Each question answered postiviely is given a score of 1. Total score possible is 4. A higher score indicates worse dyspnea. A difference between the score at end of treatment minus baseline is performed. A negative score indicates improvement. Comparing the difference between the 2 arms (placebo and ranolazine) is performed.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Ischemic cardiomyopathy patients on optimal medical treatment.

Unless contraindicated, all cardiomyopathy patients should be treated with a beta blocker and an ACEI/ARB.
-
Anginal chest pain or dyspnea
-
Documentation of non treatable or optimally treated coronary artery disease
-
Ejection Fraction of less than or equal to 40%
Exclusion Criteria:
-
Less than 18 years of age
-
Pregnant or breast feeding
-
Patients with non ischemic cardiomyopathy
