abstract

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: patients with chest pain, and intermediate risk for cad underwent stress test with bruce standard method by treadmill, and myocardial perfusion spect scan with tc-99m mibi and the results were compared to the angiography as the gold standard. analysis of the data was performed by spss11.5 soft ware. results: the study was performed on 89 patients (mean age: 55.5, min: 29 max: 80) including 53 man and 36 women. exercise stress test had 54% sensitivity, 65% specificity, 68% ppv, 50% npv, while for myocardial perfusion scan sensitivity was 94%, specificity 94%, ppv 96%, and npv 92%. correlation between involved walls in myocardial perfusion scan with stenotic artery in angiography was 77.6%, while this value was 32.7% for exercise stress test. there was also relationship between degree of stenosis determined by angiography and severity of ischemia detected by myocardial perfusion scan. conclusion: myocardial perfusion scan is of great value in detection of cad with sensitivity and specificity far better than exercise stress test. it is suggested that this noninvasive study being considered the first diagnostic method for patient at risk for coronary artery disease.

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...

Comparison of dipyridamole – induced electrocardiographic changes and myocardial perfusion imaging in diagnosis of coronary artery disease [Persian]

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 1...

The prognostic value of stress/rest gated myocardial perfusion SPECT in patients with known or suspected coronary artery disease

Introduction:Gated myocardial perfusion SPECT has diagnostic and prognostic values in coronary artery disease (CAD). We tried to determine prognostic values of the left ventricular perfusion & functional indices as well as transient left ventricular dilation (TID) derived from gated myocardial perfusion SPECT. Methods: 1820patients who underwent gated myo...

Dobutamine stress myocardial perfusion imaging in coronary artery disease.

The accurate noninvasive diagnosis and functional evaluation of coronary artery disease is an important step in selecting the appropriate management strategy. Dobutamine stress myocardial perfusion imaging is an alternative to exercise in patients with limited exercise capacity. In many centers, the test is performed on patients who have a contraindication for vasodilator stress testing. Recent...
