Abstract

Coronary angioplasty and pressure tracing records of patients with coronary artery stenosis and subsequent hyperemia conditions were obtained and analyzed. Fractional flow reserve (FFR) was calculated and plotted against percent of area stenosis. Under adenosine-induced hyperemia, FFR decreased. The extent of decrease is determined by the percent of stenosis and the responsiveness of intramural coronary artery.
