Purpose

The purpose of this study is to determine if regadenoson is as safe and effective as adenosine when used in the cardiac catheterization lab during measurement of coronary flow reserve and fractional flow reserve. The study hypothesis is the assessment of Fractional Flow Reserve (FFR) in the catheterization lab can be performed with equivalent accuracy when hyperemia is induced with IV Regadenoson compared with IV Adenosine without compromising patient safety.

Primary Outcome Measures:

Difference in FFR and Coronary Flow Reserve measurements between IV adenosine and IV regadenoson [ Time Frame: Every 30 seconds during infusion through 5 minutes post infusion of adenosine and regadenoson. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Monitor for potential side effects after IV adenosine and IV regadenoson administration such as chest pain, headache, flushing, nausea or arrhythmias [ Time Frame: Every 30 seconds during infusion through 5 minutes post infusion ] [ Designated as safety issue: Yes ]

Estimated Study Completion Date:	August 2013
Estimated Primary Completion Date:	May 2013 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Active Comparator: Adenosine Adenosine infusion will be compared to Regadenoson for safety/side effects. Arterial blood pressure, coronary pressure, heart rate, oxygen saturation and coronary flow, FFR, and coronary flow velocity will be assessed. Safety will be assessed by monitoring for any side effects such as chest pain, headache, flushing, nausea, or arrhythmias.	Drug: adenosine Measuring FFR and Coronary Flow Reserve after administration of IV adenosine 140 mcg/kg/min for 2 minutes.

Other Name: Lexiscan Drug: Adenosine Injection of IV Adenosine for 2 minutes at rate of 140mg/kg to dilate coronary arteries and provoke maximal hyperemia
Active Comparator: Regadenoson Once the mean coronary flow velocity returns to within 15% pre-dose value then Regadenoson IV injection will be given at 0.4 mg 5/ml- 0.08mg/ml. Then, a 5 cc saline flush will be administered.	Drug: regadenoson Measuring FFR and Coronary Flow Reserve after administration of IV regadenoson 0.4 mg over 10 seconds. Other Name: Lexiscan
