Adenosine is a frequently used pharmacologic stress agent in myocardial perfusion imaging. Its safety profile is well established, and most of its side effects are mild and transient. Coronary vasospasm occurs occasionally during or after adenosine stress test in rare cases, which may lead to seriously adverse outcomes. This study reported 3 such cases(More)
OBJECTIVE To assess the value of (99m)Tc-N-NOET ((99m)Tc-N-ethoxy-N-ethyl dithiocarbamato-nitrito) myocardial perfusion SPECT for the diagnosis of coronary artery disease. METHODS A total of 42 patients [mean age (54 +/- 9) years, 35 men] with suspected chest pain were included in this study. 740 MBq of (99m)Tc-N-NOET was injected intravenously during(More)
OBJECTIVE To evaluate the impact of viable myocardium assessed by (99)Tc()m-MIBI SPECT and (18)F-fluorodeoxyglucose (FDG) PET imaging in patients with left ventricular aneurysm (LVA) underwent revascularization (RVS). METHODS Forty-six consecutive patients with LVA (mean LVEF 36% +/- 7%), underwent (99)Tc(m)-sestamibi SPECT and (18)F-FDG PET examinations(More)
INTRODUCTION The relationship between luminal stenosis measured by coronary CT angiography and stress-induced ischemia by SPECT myocardial perfusion imaging is not clearly defined. The aims of this study were to evaluate the relationship between stenosis severity by coronary CT angiography and abnormal SPECT finding and to explore the impact of clinical(More)
OBJECTIVE To evaluate the myocardial perfusion and function in patients with hypertrophic obstructive cardiomyopathy (HOCM) before and after percutaneous transluminal septal myocardial ablation (PTSMA). METHODS Sixty-eight patients with hypertrophic obstructive cardiomyopathy were included and (99)Tc(m)-MIBI SPECT MPI was applied before and at 1 week(More)
To evaluate the change of perioperative cell mediated immunity after cardiac operation with cardiopulmonary bypass (CPB), so as to provide some information for timely prevention and treatment against postoperative immunological disorder, 40 patients were studied. By searching for the effects of CPB and anesthesia, interleukin-2 receptor (IL-2R) expression(More)
BACKGROUND No-reflow after emergency percutaneous coronary intervention (PCI) for acute ST segment elevation myocardial infarction (STEMI) is related to the severe prognosis. The aim of this study was to evaluate the efficacy of Tongxinluo, a traditional Chinese medicine, on no-reflow and the infarction area after emergency PCI for STEMI. METHODS A total(More)
To confirm that shortened acquisition time or reduced-activity dose in single-photon emission computed tomography (SPECT) myocardial perfusion imaging reconstructed with Astonish software (AS) does not compromise image quality or diagnostic accuracy. One hundred patients referred for SPECT myocardial perfusion imaging were prospectively studied. The(More)
OBJECTIVE The aim of this study was to assess the accuracy of adenosine (99m)Tc-MIBI myocardial perfusion SPECT for the diagnosis of coronary artery disease. METHODS A total of 89 patients [mean age (57 +/- 9) years,62 men, 27 women] were included in this study. Adenosine was infused intravenously at a rate of 140 microg.kg(-1).min(-1) for 6 minutes. At(More)
OBJECTIVE To explore the infarct sites in patients with inferior wall acute myocardial infarction (AMI) concomitant with ST segment elevation in leads V1-V3 and leads V3R-V5R. METHODS Five patients diagnosed as inferior, right ventricular, and anteroseptal walls AMI at admission were enrolled. Electrocardiographic data and results of isotope(More)
