Variation in heart rate influences the assessment of transient ischemic dilation in myocardial perfusion scintigraphy

BACKGROUND Transient arrhythmias can affect transient ischemic dilation (TID) ratios. This study was initiated to evaluate the frequency and effect of normal heart rate change on TID measures in routine clinical practice. METHODS Consecutive patients undergoing stress/rest sestamibi gated myocardial perfusion scintigraphy were studied (N = 407). Heart rate at the time of stress and rest imagi...

Comparison of transient ischemic dilation ratios in SPECT and SPECT-CT myocardial perfusion imaging in the low pre-test probability group

Introduction: The main purpose of this study was to compare transient ischemic dilation (TID) ratios in SPECT-low dose CT and SPECT Myocardial Perfusion Imaging (MPI) by application of different quantitative programs and quantify the possible shift in the upper normal limits of TID ratio in the SPECT-CT MPI. Methods: 149 Patients with low pre-test probability for coronary artery disease (CAD),...

Different aspects of transient ischemic dilation

  Transient ischemic left ventricular dilation (TID) is a marker of severe and extensive coronary artery disease as well as an increased risk of adverse outcomes. The patients with more severe and extensive ischemia, multivessel-type of perfusion abnormality as well as patients with left anterior descending artery (LAD) territory perfusion abnormality have more probab...

The myocardial perfusion scintigraphy in asymptomatic diabetic patients

Introduction: Asymptomatic diabetic patients are at increased risk of cardiovascular complications. Myocardial perfusion scan may be effective in risk evaluation in this population. Methods: 106 asymptomatic diabetic patients (age: min: 37, max: 82, mean: 57.73±8.88), including 56 females (52.8%) and 50 males (47.2%) were enrolled in the study. Myocardial perfusion scintigraphy was performed b...
