Brief summary
The investigators will test if upfront dosing of Ranolazine can reduce myocardial biomarker release (CK-MB, Troponin) post percutaneous coronary intervention (PCI).
Detailed description
Ranolazine has been demonstrated to decrease angina, ischemia on perfusion imaging, improve diastolic function, and cardiac metabolism. Furthermore it has been associated with reduced cardiac arrhythmias, including non-sustained ventricular tachycardia and atrial fibrillation. It has not been studied as an acute cardioprotective agent in percutaneous coronary intervention (PCI). We hypothesize that upfront administration of Ranolazine could decrease the myocardial injury associated with PCI due to all the factors listed above (i.e. precondition the myocardium). We plan to screen all patients scheduled for an elective coronary angiogram. Those who meet criteria and consent will be randomized to either receive Ranolazine or placebo twice a day for 3 days leading up to the PCI.
Interventions
Drug: Placebo Oral dose twice per day for 3 days leading up to PCI
Drug: Ranolazine 1000 mg Oral dose twice per day for 3 days leading up to PCI

Outcome results
CK-MB
CK-MB labs will be drawn 8-10 hrs after PCI or at discharge whichever comes first
Time frame: 8-10 hrs post PCI
Population: For the single subject completing the PCI intervention, CK-MB was not done because the CK level was below the threshold running the CK-MB test.
Troponin
Troponin labs will be drawn 8-10 hrs after PCI or at discharge whichever comes first
Time frame: 8-10 hrs post PCI
Population: Of the 4 Ranolazine Group subjects, 1 was withdrawn for pre-procedure study drug non-compliance; 3 had no PCI intervention. Of the 2 Placebo Group subject, 1 had no PCI intervention. The only subject undergoing PCI intervention was from the Placebo Group and was thus the only subject undergoing this protocol required test.

TIMI Flow Rate (Grade)
This TIMI classification was developed by the TIMI (Thrombolysis In Myocardial Infarction) study group to semiquantitatively assess coronary artery perfusion beyond point of occlusion on coronary angiography.\* TIMI Grade \[Description\] TIMI 0 - no perfusion \[no antegrade flow beyond the point of occlusion\] TIMI 1 - penetration without perfusion \[faint antegrade coronary flow beyond the occlusion with incomplete filling of the distal coronary bed\] TIMI 2 - partial perfusion \[delayed or sluggish antegrade flow with complete filling of the distal territory\] TIMI 3 - complete perfusion \[normal flow with complete filling of the distal territory\] \*(see http://radclass.mudr.org/content/timi-grade-flow-grading-coronary-blood-flow-during-coronary-angiography) TIMI 0 is the least favorable grade. TIMI 3 is the most favorable grade.
Time frame: TIMI Flow Rate (Grade) is assessed immediately after an interventional reperfusion attempt during a PCI (Percutaneous Coronary Intervention) procedure.
Population: The only subject undergoing PCI intervention was from the Placebo Group and was thus the only subject for whom this protocol required data point was collected.
