Cardiomyopathy, Chest Pain, Dyspnea
Conditions
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.
Interventions
1000 mg Ranexa orally once daily titrated as tolerated after 1 week up to taking 1000 mg twice daily.
1000 mg placebo orally once daily titrated as tolerated after 1 week up to taking 1000 mg twice daily.

Eligibility
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
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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 Questionnaire | 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. |

Outcome results
Anginal Frequency
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.
Time frame: 12 weeks
Population: Patients receiving ranolazine for 6 weeks and crossed over to placebo or vice versa. Higher number on the angina scale indicates less angina
| Arm | Measure | Value (MEAN) |
|---|---|---|
| Ranolazine | Anginal Frequency | 86.67 units on a scale |
| Placebo | Anginal Frequency | 74.44 units on a scale |
Dyspnea Assessed by the Rose Dyspnea Questionnaire (RDQ)
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.
Time frame: 12 weeks
Population: Patients with dsypnea. The score reflects difference between baseline and following treatment with ranolazine or placebo
| Arm | Measure | Value (MEAN) |
|---|---|---|
| Ranolazine | Dyspnea Assessed by the Rose Dyspnea Questionnaire (RDQ) | -0.45 units on a scale |
| Placebo | Dyspnea Assessed by the Rose Dyspnea Questionnaire (RDQ) | -0.34 units on a scale |
Quality of Life Questionnaire
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.
Time frame: 12 weeks
| Arm | Measure | Value (MEAN) |
|---|---|---|
| Ranolazine | Quality of Life Questionnaire | 72.22 units on a scale |
| Placebo | Quality of Life Questionnaire | 66.67 units on a scale |
