Abstract
|
|
|
Despite of having smaller infarct size and better left ventricular function, patients with non Q wave myocardial infartion(MI) have been reported high rate of late mortality due to recurrent MI, precipetated by more residual viable tissues in the
perfusion zone of infarct-related arteries. To evaluate the clinical characteristics and coronary angiographic findings of non Q wave myocardial infarction, 23 patients with non-Q wave myocardial infarction who were admitted between Oct. 1993 and
Sep.
1994 were reviewed and analyzed retrospectively.
@ES The results were as follows:
@EN 1) The moan age was 40-50 years. Male to female ratio was 6:1. Most common risk factor was smoking
2) Most common electrocardiographic finding was anterior or lateral wall infarction. Five patients(21.7%) among total twenty three patients had normal electrocardiographic finding
3) ) Selective coronary angiography was performed in nineteen patient. Each patient was classified as having one-,two-,three vessel coronary artery disease. In one case(5.3%). Angiographic finding was normal. Seven cases(36.8%) were one vessel
disease.
And four cases were three vessel disease. Coronary artery with complete stenosis(100%) was present in five patients and low grade obstruction (<50%) was present in three patients.
4) Formation of collateral circulations was observed in 73.7% and incidence of abnormal left ventricular wall motion was less frequent.
