Outcome Measures
Primary Outcomes (1)
Coronary Flow Reserve
Compare changes in coronary flow reserve as measured by cardiac PET(Positron Emission Tomography) in patients receiving Ranolazine versus control. This is the ratio between stress and rest myocardial blood flow in response to stress.
4 weeks
Study Arms (2)
Intervention Group
EXPERIMENTALSubjects will take extended release Ranolazine for 4 weeks. Subjects will take 500 mg twice daily for the first week and then 1000 mg twice daily for remaining period (Dosing will be adjusted with concomitant use of diltiazem, verapamil, erythromycin, simvastatin or metformin).
Placebo Control
PLACEBO COMPARATORSubjects will take placebo pill twice daily for 4 weeks.
Interventions
Subjects will take the extended-release Ranolazine for a total of 4 weeks. Subjects will take 500 mg twice daily for the first week and then 1000 mg twice daily for remaining period (Dosing will be adjusted with concomitant use of diltiazem, verapamil, erythromycin, simvastatin or metformin).
