Prognostic significance of ischemic electrocardiographic changes during adenosine infusion in patients with normal myocardial perfusion imaging.
BACKGROUND The development of ST-segment depression during adenosine myocardial perfusion imaging (MPI) has been shown to be an independent predictor of subsequent cardiac events and worse outcome, particularly in association with ischemic defects. However, the prognostic significance of ST-segment depression with adenosine in patients with normal MPI is not known. METHODS AND RESULTS We perf...
متن کاملPrevalence and significance of electrocardiographic changes and side effect profile of regadenoson compared with adenosine during myocardial perfusion imaging.
BACKGROUND Significance of electrocardiogram (EKG) changes associated with regadenoson as well as side effects compared to adenosine in a real world, unselected population is unknown. METHODS AND RESULTS Three hundred ninety six consecutive patients undergoing either adenosine or regadenoson-based single-isotope (Technetium 99c) nuclear images were evaluated. A standard form documenting side ...
متن کاملPrognostic significance of ischemic electrocardiographic changes during vasodilator stress testing in patients with normal SPECT images.
BACKGROUND Patients with ischemic electrocardiographic (ECG) findings during exercise stress testing but normal perfusion images generally have a low risk of cardiac death or myocardial infarction (<1% per year). During vasodilator stress testing, however, the prognostic significance of the combination of normal perfusion images and ischemic ECG changes is unknown. METHODS AND RESULTS Among 5...

متن کاملComparison 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...
