Left ventricular thrombus incidence and behavior studied by serial two-dimensional echocardiography in @entity583 : left ventricular wall motion, systemic XXXX and oral anticoagulation.

@entity1 @entity64 @entity583 @entity887 @entity715
Serial two-dimensional echocardiography was performed to detect left ventricular @entity715 in 92 consecutive @entity1 with a confirmed first @entity583 . Thirty left ventricular thrombi were diagnosed in these 92 @entity1 . The cumulative percent of identified @entity715 in each echocardiographic examination in the surviving @entity1 was 27% at less than 24 h; 57% at 48 to 72 h; 75% at 1 week and 96% at 2 weeks. The @entity715 shape was defined as mural in 53% and protruding in 47% of @entity1 . Systemic @entity887 ( @entity64 ) was noted during hospitalization in two @entity1 with a protruding @entity715 . At 12 weeks of follow-up, @entity1 with @entity715 had poorer (and almost unchanged from baseline) global left ventricular function as expressed by wall motion score compared with that of @entity1 without @entity715 , who exhibited significant improvement. Global left ventricular wall motion in @entity1 with persisting or resolved @entity715 was similar during follow-up. Apical wall motion worsened in 70% of the @entity1 with persisting @entity715 and in 25% of the @entity1 with resolved @entity715 (p less than 0.1). In the 22 surviving @entity1 with @entity715 , resolution or change in @entity715 shape or size was noted in 14 of the 15 patients receiving anticoagulant therapy and in 4 of the 7 untreated @entity1 . Six of the 18 @entity1 with an early- (48 to 72 h) and none of the 12 @entity1 with a later-formed @entity715 died. Maximal serum enzyme levels, percent with Killip functional class III to IV and left ventricular wall motion score were higher in the @entity1 with an early- than in those with a later-formed @entity715 .(ABSTRACT TRUNCATED AT 250 WORDS)
