Abstract 14070: Significant Correlation Between Coronary Fractional Flow Reserve and Dobutamine Stress Echocardiography in Patients With Moderate Coronary Artery Disease

IntroductionBoth the fractional flow reserve (FFR) measurement and the dobutamine stress echo (DSE) are accepted diagnostic methods to indicate revascularisation of a moderate coronary stenosis (CAS). The prospective comparative data of these two functional tests are limited for CAS in stable (SCAD)...

Description
Summary:IntroductionBoth the fractional flow reserve (FFR) measurement and the dobutamine stress echo (DSE) are accepted diagnostic methods to indicate revascularisation of a moderate coronary stenosis (CAS). The prospective comparative data of these two functional tests are limited for CAS in stable (SCAD) and bystander coronary artery disease. We sought to compare these tests in these clinical settings in a prospective study.MethodsPatients were included with CAS (30-70 % diameter) either with SCAD or bystander coronary artery disease revealed by coronary angiogram performed for ACS treatment. In this case the culprit vessel was excluded and the FFR study was deferred for a month. The FFR study was performed within 4 weeks of DSE. The target vessel considered abnormal if FFR was
