Frequency of cerebral microembolisms (high intensity transient signals, HITS) in acute myocardial infarction has been reported about 17%. The factors that influence on microembolism after myocardial infarction (MI) are not definitive. Type of MI, Ejection fraction, Hx of Streptokinase is the factors that were studied. </font></font></font><b><font color="#211d1e" size="2"><font color="#211d1e" size="2"><p style="DIRECTION: ltr" align="justify">Methods: </p></font></font><font color="#211d1e" size="2" face="Times New Roman,Times New Roman"><font color="#211d1e" size="2" face="Times New Roman,Times New Roman"><font color="#211d1e" size="2" face="Times New Roman,Times New Roman">During three years we studied the frequency of cerebral microembolisms in AMI patients, we studied forty patients with microembolism as a case group and ninety patients without microembolism as a control group. We detected microembolism in patients by transcranial doppler study within 72 houre after myocardial infarction. Two-dimensional echocardiogram was performed for all patients during hospitalization. Excluding criteria were prosthetic heart valves, carotid stenosis >50% and poor window for TCD monitoring. </font></font></font><b><font color="#211d1e" size="2"><font color="#211d1e" size="2"><p style="DIRECTION: ltr" align="justify">Results: </p></font></font><font color="#211d1e" size="2" face="Times New Roman,Times New Roman"><font color="#211d1e" size="2" face="Times New Roman,Times New Roman"><font color="#211d1e" size="2" face="Times New Roman,Times New Roman">number of patients who had history of receiving SK were significantly more common in case group in comparison to control group. OR 2.4 CI(1.1-5.2) The frequency was more prevalent in anterolateral MI in comparison to inferior MI.OR=3.3 CI(1.4-7.4). Ejection fraction has no significant effect on frequency of microembolism. OR 0.5 CI(0.2-1.3).Hypokinesia is also a risk factor for increasing risk of microembolism.
