Figure 5 Correlation between DSVR and the changes in RWM and EF for the patients with infarcts in the left anterior descending coronary artery territory. The DSVR correlated positively with the RWM (left panel) and with the EF (right panel) in the range of DSVR values <3.0. This correlation for RWM is stronger than that for EF. DSVR = diastolic to systolic velocity ratio of coronary flow; EF = ejection fraction; RWM = regional wall motion.
