Brief Summary
This is a single-center double blind, placebo controlled study of patients undergoing a cardiac catheterization where the need for a percutaneous coronary intervention (PCI) is anticipated or will be determined during the early diagnostic phase. The study will assess the use of intracoronary nicardipine vs. sterile saline injection in reducing the index measurement of microcirculatory resistance (IMR). Fifty consecutive patients presenting to the Thomas Jefferson University (TJUH) Cardiac Catheterization lab will be randomized in a 1:1 fashion to receive either intracoronary nicardipine or sterile saline injection prior to PCI. IMR values will be assessed pre and post procedure. Data on clinical outcomes and adverse events will be collected by phone at 30 days and 1 year following the procedure.

Outcome Measures
Primary Outcomes (1)
Change in Index of Microcirculatory Resistance (IMR)
IMR is an intracoronary artery pressure measurement obtained during cardiac catheterization, and is a reliable indicator of microvascular dysfunction
From the start of the PCI procedure to immediately following the PCI procedure
Secondary Outcomes (4)
Post-Procedure myocardial Infarction (PMI)
6-8 hours post procedure
Post-Procedure myocardial Infarction (PMI)
12-18 hours post procedure
Major Adverse Cardiac Event
30 Days following procedure
Major Adverse Cardiac Event
I year following procedure
Study Arms (2)
Intracoronary Nicardipine
EXPERIMENTAL200 mcg intracoronary injection of nicardipine prior to PCI, with potential for additional 100 mcg nicardipine before stent placement, balloon post-dilation, and before post-PCI IMR measurement.
Sterile Saline
PLACEBO COMPARATORInjection of sterile saline prior to PCI, with potential for additional saline injections before stent placement, balloon post-dilation, and before post-PCI IMR measurement.
Interventions
200 mcg intracoronary nicardipine injection prior to PCI followed by an additional 2-4 doses of 100 mcg intracoronary nicardipine depending on complexity of PCI
Bolus of intracoronary sterile saline injection prior to PCI followed by an additional 2-4 doses of sterile saline depending on complexity of PCI
