  Purpose

The purpose of this study is to evaluate the safety and effectiveness of the peripheral IV continuous infusion without the insertion of central venous vascular access method in the achievement of steady-state maximal coronary hyperemia compared with the central IV continuous infusion method.

Primary Outcome Measures:
  • compare fractional flow reserve at maximal hyperemia [ Time Frame: interval of 10 minutes ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • compare the time to maximal hyperemia and changes in heart rate [ Time Frame: interval of 10 minutes ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 66
Study Start Date: December 2009
Study Completion Date: May 2011
Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: FFR via central venous line Other: FFR via central venous line
Patients with intermediate coronary artery stenosis were consecutively enrolled. FFR was measured by a standard intravenous (IV) adenosine infusion (140 μg•min−1•kg−1) via Rt central femoral vein.
Experimental: FFR via peripheral vein Other: FFR via peripheral venous line
Patients with intermediate coronary artery stenosis were consecutively enrolled. FFR was measured by a standard intravenous (IV) adenosine infusion (140 μg•min−1•kg−1) via continuous peripheral vein.
