Ability of the no-reflow phenomenon during an XXXX to predict @entity1002 at one-month follow-up.

Despite angiographically successful opening of an @entity1188 -related vessel within a 6-hour time frame, some @entity1 do not recover left ventricular regional wall function in the @entity1188 zone after an @entity583 ( @entity583 ). Recent evidence suggests that this finding is due to the no-reflow phenomenon, or failure to recover tissue perfusion despite @entity1 epicardial arteries. We performed myocardial contrast echocardiography to assess tissue perfusion before and after opening of an @entity1188 . Coronary angiograms, regional wall motion scoring, and myocardial contrast enhancement were graded by 3 observers. Of 24 @entity1 with @entity583 , 7 (29%) failed to recover tissue perfusion in > or = 1 region of myocardium. Of 106 regions subtended by the @entity1188 , 16 (15%), 43 (41%), and 47 (44%) regions had no-reflow, partial, or normal flow, respectively, after arterial patency was established. There was a spectrum of reperfusion patterns ranging from no-reflow to normal perfusion. One-month follow-up angiographic and myocardial contrast echocardiographic studies were performed in 12 of the 24 @entity1 . At 1 month, all segments of myocardium that had immediate normal perfusion had regained normal wall motion. In contrast, 17 segments that had partial or no-reflow were identified. Of these 17, 3 regained normal function, 10 segments were @entity5048 , and 4 segments were @entity2845 . We conclude that myocardial contrast echocardiography can be used to identify the no-reflow phenomenon in up to 29% of @entity1 with @entity583 . Additionally, we found that the immediate-reflow pattern can predict degree of @entity1002 at 1-month follow-up.
