Phase analysis of radionuclide angiography in acute myocardial infarction

Standard deviation of the histogram of left ventricular phase distribution (SDP-LV) obtained by radionuclide angiography (RNA) was studied in 75 acute myocardial infarction (AMI) patients, 37 with anterior or anteroseptal (Group A) and 38 with inferior, inferolateral or posterior necrosis (Group I). In order to evaluate sensitivity, specificity and accuracy of SDP-LV compared to ejection fraction (EF) and peak filling rate (PFR), 16 controls and 29 patients with coronary artery disease with normal kinesis proved by angiogaphy were studied. Patients were also compared according to normal or abnormal EF and PFR.
