Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A TIMI frame count is measured by counting the angiographic image cine frames during a head of radiocontrast column runs from the entry of left anterior descending artery (LAD) to the distal end.
A coronary clearance frame count is measured by counting the angiographic image cine frames during a tail of radiocontrast column runs from the entry of LAD to the distal end.
Baseline angiography is performed without any stimulation and hyperemic angiography is performed after intracoronary injection of adenosine 300ug or nicorandiol 2mg.
