چکیده

introduction: this study evaluated the diagnostic value of the dipyridamole induced electrocardiuogram (ecg) cahnges, comparing with myocardial perfusion imaging. materials and methods: 222 patinets were studied with dipyridamole infusion (based on ecg criteria) as well as dipyridamole-myocardial perfusion imaging (mpi). results: abnormal dipyridamole test and abnormal mpi were noted in 11% and 56.3% of patients, respectively. of 25 postive dip. tests, 20 patients (80%) showed abnormal mpi, more commonly (43.3%) as fixed lesion associated with ischemia. of dipyridamole negative group, 53.3% showed abnormal mpi. normal mpi was consistent with normal dipyridamole test in about 94%, while in presence of abnormal mpi, 16% had abnormal dipyridamole test. conclusion: positive dipyridamole test more likely implies abnormal mpi. more severe cad in more frequency of positive dipyridamole test. coronary artery disease (cad) could not be reliably excluded in presence of normal dipyridamole stress test.

Myocardial perfusion scan accuracy in detection of coronary artery disease - Comparison with exercise stress test [Persian]

Introduction: In patients with coronary artery disease (CAD) noninvasive evaluation for detection of ischemia is important to avoid invasive interventions like angiography. Exercise stress test is conventionally the first study used in evaluation of CAD. Considering the noninvasive nature of the myocardial perfusion scan, we decided to compare its accuracy with stress test. Methods: Patie...

Diagnostic Accuracy of Gated-SPECT Myocardial Perfusion Imaging and Exercise Stress Test for Diagnosis of Coronary Artery Disease

Background and Objective:Accurate diagnosis of CAD using noninvasive procedures is of great importance. The aim of the study is to assess diagnostic accuracy of myocardial perfusion imaging and compare it with exercise stress test in order to decipher a more accurate and cost-effective method for CAD detection. Materials and Methods:Of 430 consecutive patients suspected with CAD, 104 performed...

Diagnosis of coronary artery disease by radionuclide myocardial perfusion imaging.

D espite advances in the understanding of the pathophysiology of atherosclerosis and an applaudable reduction in cardiovascular mortality over the past 30 years, coronary artery disease (CAD) remains an important cause of mortality and morbidity in the UK. While primary prevention of CAD is a priority for modern medicine, so too is the need for development of non-invasive techniques for imaging...
