Changes in coronary anatomy and left ventricular function from the acute to the chronic stage of XXXX .

@entity1 @entity64 @entity2845 @entity1188 @entity583 @entity850
Coronary angiography was performed in the acute stage of @entity583 in 65 @entity1 . The @entity1188 was occluded in 50 @entity1 ; it was narrowed greater than 90% in the remaining 15 @entity1 . Control angiography was performed 55 +/- 46 d after acute @entity583 in 18 @entity1 . In the chronic stage, five of thirteen previously occluded vessels showed antegrade filling of the distal segment. The narrowing at the site of previous obstruction was 80--95%. In two of five @entity1 with a @entity850 , the lumen of the @entity1188 was clearly larger in the chronic stage. The end-diastolic volume index increased significantly from 86 +/- 23 ml/m2 in the acute stage to 110 +/- 35 ml/m2 in the chronic stage (p less than 0.001). The increase in the end-systolic volume index from 42 +/- 15 ml/m2 to 63 +/- 31 ml/m2 was also statistically significant (p less than 0.005). @entity64 volume index, ejection fraction, and the length of the @entity2845 segment (AKS) did not change significantly. There was a weak correlation between the end-systolic volume index and the length of the AKS in the acute stage (r = 0.489, p less than 0.05) and a better correlation in the chronic stage (r = 0.602, p less than 0.01). The ejection fraction and the length of the AKS correlated in the chronic stage only (r = 0.795, p less than 0.001).
