OBJECTIVE: @entity67 precedes @entity299 during the development of @entity741 . Detecting @entity67 during stress test for @entity453 ( @entity453 ) could improve diagnostic sensitivity of the test. Flow propagation velocity ( @entity17249 ) derived from color M-mode Doppler has been proposed as a sensitive marker to detect @entity67 . METHODS: The FPVs at baseline and at peak @entity452 infusion were measured using color M-mode Doppler during @entity452 stress echocardiography in 90 @entity1 . The results are compared among the groups divided on the results of coronary angiography. RESULTS: The @entity17249 was similar at baseline among the groups. At peak @entity452 infusion, the @entity17249 increased significantly in the non- @entity453 group (from 56    19 cm/s to 66    25 cm/s), whereas it failed to increase in the groups with @entity453 . As a result, the peak @entity17249 was significantly lower in the groups with @entity453 than in the non- @entity453 group. Receiver operating characteristic analysis showed that the peak @entity17249 and /\ @entity17249 had good diagnostic property to detect @entity453 (the areas under the curves were 0.77 and 0.73, respectively). Adopting these @entity17249 criteria, sensitivity of DSE was improved. CONCLUSION: @entity17249 measurement during DSE detects @entity63 @entity1002 . Adding the assessment of peak @entity17249 to conventional DSE increases the sensitivity and the ability to reliably exclude @entity453 .

Early diastolic flow propagation velocity detects induced XXXX during @entity452 stress echocardiography.
