Abstract:
17 cases of acute myocardial infarction with no or insignificant narrowing of major coronary arteries on angiogram and without any-other types of heart disease were found in a series of 133 consecutively studied patients with acute myocardial infarction(12,7%). There were no differences in risk factors between groups. Although the infarction site were similar in both groups, the patients with normal coronary arteries had fewer complications during hospitalization(p<0.05) and lesser ST segment change during the exercise test before discharge(p<0.05). In the hemodynamic fingings, cardiac index, left ventricualr and diastolic pressure and resional wall motion were similar in both groups of the patients, but ejection fraction was higher(p<0.05) in the patients with the normal coronary arteries. In conclusion, it could be predicted that the acute myocardial infarction with the normal coronary arteries would have the better prognosis. And a transient coronary occlusion, as the most likely pathogenic mechanism of the acute mtocardial infarction with normal coronary arteries, might be studied in the aspect of the thrombosis following lysis, the coronary artery spasm and the platelet aggregation.
