title: Histopathologic coronary patterns in people with acute myocardial infarction and PTCA.
abstract: We studied coronary artery specimens histologically in 96 patients who died from acute myocardial infarction(AMI), to assess those who could benefit from in-hospital percutaneous transluminal coronary angioplasty (PTCA). For the left anterior descending artery, old stenoses within 1 cm from its origin in 80 cases (83.3%), coronary narrowing over 90% and occlusive thrombi in 40 observations (41.6%) were seen. Left main artery showed proximal stenoses with an occlusive thrombus in 4 cases (41.6%). Left circumflex artery had stenoses within 1 cm from its origin in 32 cases (33.3%), with an occlusive thrombus 6 times (6.25%) and coronary narrowing 75%. Right coronary artery showed stenoses in the proximal and midportion respectively in 20 (20.8%) and 36 cases (37.5%), with 26 occlusive thrombi (27%) and coronary narrowing 85%. Four cases (4.16%) had minimal coronary changes. The patients who had one, two and three vessel disease were 32 (33.3%), 32 (33.3%) and 28 times (29.16%) respectively. Only one-third of patients could benefit from PTCA.
