[Morphological and histomorphometric characterization of the myocardium in patients with aorto-coronary venous bypass. An autopsy study].
Morphological and histomorphometric investigations were performed in 29 autopsy hearts from patients with aorto-coronary venous bypass. 14 of them (48%) had died of acute myocardial infarction or re-infarction and 9 (31%) of postoperative cardiac failure. Bypasses had been obstructed by thrombi in nearly 50% of those who died of infarction. Average heart weight of 548 +/- 128 g was found to be correlated with the left-ventricular myocardial cell diameter, but it did not reflect the extent of hypertrophy in chronically insufficient hearts. Stenotic coronary arteriosclerosis and increase in left-ventricular connective tissue in the myocardium to a level of 19.5 +/- 6.0 vol. % completed the pattern of severest cardiac damage and were of substantially adverse impact upon postoperative survival of patients thus affected.
