Objective Compare the morphology of atherosclerotic plaquesmgiographically and histopathologically in acute myocardialmfarction m order to accumulate experience in recognizing plaquerupture and thrombus by angiogrames.Material and methods 16postmortem cases of acute myocardial infarction were studied.The coronary arteries were romoved en block,filled with barium the lumen and ridiographed.Then the arteries wereontinuously insetted and routin HE sections were made.Results 16 cases had plaque ruptures and thrombi.Among the total98 blocks,21 had plaque ruptures on which 20 thrombiccur(95.23%).while the other 777 unrupured blocks had only 2hrombi(0.25%).The difference was significant(p【0.001).Therupture mostly occur on unstable plaques.The ruptured plaqueswith thrombi had different angiographical morphology withunruptured plaques.The former had irregular borders andunraluminal lucencies;while the Iatter had smooth borders and nointraluminal lucencies.Conclusions Plaque ruprure withthrumbus was the major cause of acute myocardial infarction andthe ruptured plaques with thrombus had different angiographicalapperances with unruptured plaques.
