Study Details

Study Description

Brief Summary

This is a proof of concept trial using ranolazine, a medication, in patients with known Coronary Artery Disease and reduced left ventricular function, EF < 40%. We propose that ranolazine therapy will result in demonstrative improvements in cardiac function that can be objectively assessed using the parameters measured with CPET. We propose that demonstrative improvement in CPET parameters on ranolazine will translate into improved patient outcomes for this patient population.

Detailed Description

Selected patients will undergo a CPET evaluation. The initial CPET will identify patients with underlying ischemia and serve as a baseline study. Ischemia will be assessed using: 1) peak VO2: measures the peak transport of O2 to the tissues when O2 extraction from the blood is maximal; 2) the anaerobic threshold (AT): measures the sustainable work capacity in units of VO2; 3) the O2-pulse measurements at the AT peak VO2: estimate stroke volume at those levels of exercise; and 4) the relationship of O2 uptake to work rate (ΔVO2/ΔWR): provides information on the ability of the cardiac output to increase. Patients whoseCPET results meet the criteria for ischemia will be started on Ranexa 500mg BID and advanced within one week +/-4 days to 1000mg BID. A second CPET will be performed after 4 weeks +/- 4 days of maximum therapy. CPET results before and after therapy will undergo a statistical comparison. The initial off treatment CPET measurement will serve as the control to assess changes found during therapy. No medication changes or revascularization procedures will occur during the study. If patients require and undergo a medication change or a revascularization procedure, they will be excluded from the study.

Patients will be contacted at the completion of week one prior to up titration, then at the end of week two to ensure tolerance and compliance with the 1000mg BID dose. Patients will perform the second CPET study at week four +/- 1 week. The trial medication will be assessed and counted to ensure that patients have taken there allotted pill count for the duration of the study. Patients who are found to be noncompliant of less than 80% will be excluded from the study.

Arms and Interventions

Arm Intervention/Treatment
Other: Ranolazine Treatment Arm

All patients who meet the criteria of ischemia will receive ranolazine after enrollment. The initial CPET will serve as the control. The second CPET after 30-days of therapy will serve as the therapy arm. CPET parameters will be assessed and compared both on and off therapy.

Drug: Ranolazine
The intervention will be ranolazine therapy after the initial CPET. The initial CPET will identify patients with underlying ischemia and serve as a baseline study. Patients whose CPET results meet the criteria for ischemia will be started on Ranexa 500mg BID and advanced within one week +/-4 days to 1000mg BID. A second CPET will be performed after 4 weeks +/- 4 days of maximum therapy. CPET results before and after therapy will undergo a statistical comparison. The initial off treatment CPET measurement will serve as the control to assess changes found during therapy.

    Primary Outcome Measures

    1. Cardiopulmonary Exercise Test Parameters (CPET). [30 days]

      CPET parameters assessed will include the peak VO2: measures the peak transport of O2 to the tissues when O2 extraction from the blood is maximal; 2) the anaerobic threshold (AT): measures the sustainable work capacity in units of VO2; 3) the O2-pulse measurements at the AT and peak VO2: estimate stroke volume at those levels of exercise; and 4) the relationship of O2 uptake to work rate (ΔVO2/ΔWR): provides information on the ability of the cardiac output to increase.
