NCT01161121

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Difference in FFR Between IV Adenosine and IV Regadenoson

    FFR (as calculated by the ratio of lowest Pd/Pa at maximal hyperemia) was compared between hyperemia achieved with adenosine and with regadenoson

    At maximal, steady-state hyperemia

Secondary Outcomes (2)

  • Heart Rate Changes With Drug

    During drug infusion and until restoration of baseline hemodynamics

  • Side Effects of Medication Administration

    During drug infusion and until restoration of baseline hemodynamics

Study Arms (1)

Adenosine then Regadenoson

EXPERIMENTAL

Adenosine infusion will be compared to Regadenoson for efficacy and 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. Adenosine infusion will be administered at 140 mcg/kg for 2 minutes and once mean coronary flow velocity returns to within 15% of pre-dose value, Regadenoson IV bolus 0.4 mg/5 ml will be administered followed by a 5 cc normal saline flush.
