Figure 1 Coronary Flow Response to Adenosine in CSX Patients and Control Subjects
Individual and average (±SD) values of coronary blood flow response to adenosine in the left anterior descending (LAD) coronary artery, as assessed by transthoracic echo-Doppler, in cardiac syndrome X (CSX) patients and in healthy control subjects. The CSX patients are divided into those showing reversible perfusion defects (CSX LAD/CMR+) and those not showing any reversible regional perfusion defects (CSX LAD/CMR–) in the LAD territory on cardiovascular magnetic resonance (CMR) during dobutamine stress test.
