N/A 26 cases(12.0%) showed angiographically normal coronary artery. Among 217 cases of acute myocardial infarction(AMI), the patients with normal coronary arteriograms were younger than those with abnormal coronary arteriograms (p<0.05). There were no differences between the two groups in risk factors and tread- mill test. The incidence of non-Q wave infarction significantly increased in the group of patients with normal coronary arteriograms (p<0.005). Ejection fraction in gated blood pool scan and hemodynamic findings including cardiac index and left ventricular end diastolic pressure (LVEDP) were similar in both groups. Normal wall motion in the left ventriculogram was noticed more frequently in patients with normal coronary arteriogram (p<0.005). The incidence of postinfarct complication and symptomatic recurrence rate of ischemic heart disease after AMI showed no differences between the two groups. In conclusion, the incidence of AMI with normal coronary arteriogram was higher than that of other western studies. The reason for this difference is unclear, although it might be explained partially by a reported high incidence of vasospasm in our country. More data are needed especially in the aspect of prognosis, in order to establish the clinical significance of normal coronary angiogram in patients with AMI.
