Prognostic value of radionuclide ventriculography after XXXX .

@entity1 @entity712 @entity9568 @entity1188 @entity951 @entity583 @entity943 @entity1002
We have studied 50 consecutive @entity1 who had sustained their first @entity583 . Using the noninvasive technique of radionuclide ventriculography, ventricular performance, as assessed by left ventricular @entity9568 ( @entity9568 ), was measured at rest just before discharge from hospital when @entity1 were well and free from @entity712 and then at one and four months after @entity1188 , at rest and during submaximal supine exercise. Left ventricular @entity9568 was below normal in 42 @entity1 (normal range 0.43-0.71). Mean @entity9568 for those @entity1 recovering from inferior @entity1188 was 0.43 +/- 0.09 (mean +/- 1 S.D.), whereas for those who had sustained anterior @entity1188 mean @entity9568 was significantly lower, 0.33 +/- 0.13 (p less than 0.01). @entity9568 was significantly reduced (p less than 0.01) in those @entity1 whose early progress was complicated either by serious @entity943 or @entity1002 . There was only poor correlation between @entity9568 and radiographically determined heart size but global left ventricular performance correlated well with the presence of abnormalities of regional wall movement. Over the first four months low @entity9568 failed to improve in seven @entity1 with areas of dyskinesis ( @entity9568 less tha 0.30) and despite diuretic therapy five suffered further episodes of @entity712 . Excluding those with dyskinesis there were 18 @entity1 who were unable to increase @entity9568 on exercise on month after @entity1188 . Of these four already had symptoms of @entity951 but a further 10 @entity1 developed @entity951 in the subsequent three months. Poor left ventricular performance is common after anterior @entity583 , complicated in the acute phase by serious @entity943 or @entity1002 . @entity1 with persistently low @entity9568 had an increased risk of further episodes of @entity712 , whereas a fall in @entity9568 on exercise was associated with subsequent @entity951 .
