Title: Diagnostic accuracy of adenosine triphosphate stress echocardiography derived coronary flow reserve for detecting fractional flow reserve using the pressure wire
Abstract:Objective
To test the consistency of coronary flow reserve (CFR) derived by adenosine triphosphate (ATP) stress echocardiography and fractional flow reserve(FFR) using the pressure wire.
Methods...Objective
To test the consistency of coronary flow reserve (CFR) derived by adenosine triphosphate (ATP) stress echocardiography and fractional flow reserve(FFR) using the pressure wire.
Methods
A total of 78 patients were inrolled.The ATP stress pressure guide wire and echocardiography were performed immediately after the coronary angiography to assess CFR. ROC curve analysis was used to test the value of CFR for detecting FFR levels.
Results
All the patients were divided into group A (FFR>0.80, n=43) and group B (FFR 2.0 was the best cutoff value for diagnosing FFR>0.80, the area under the curve was 0.81 (95%CI 0.75~0.89), with a sensitivity of 58%, a specificity of 81%and anaccuracy of 73%.
Conclusions
CFR measured by ATP stress echocardiography is a valuable tool for detecting FFR using the pressure wire.
