Prognostic value of ECG-gated thallium-201 single-photon emission tomography in patients with coronary artery disease

Abstract

Assessment of post-stress left ventricular function by gated-SPECT provides incremental prognostic information and is useful in predicting cardiac events in patients with suspected or definite coronary artery disease.

Prognostic Value of Normal Stress Myocardial Perfusion Imaging in Japanese Population A Study Based on the J-ACCESS Study

“…20 Published prognostic studies performed in the USA in patients who underwent pharmacologic stress indicate that such patients are considered at higher risk. [6][7]23 Therefore, the annualized hard event rate of 0.63% for the present study's population is as low as that of studies conducted in the USA. [4][5][6] Risk stratification is essential to the development of evidence-based strategies for improved patient care in medicine.…”

“…2,33 Prognostic values of left ventricular functional parameters using QGS have been demonstrated by multiple studies. [1][2][3][4][5][6][7][8][9]23,36 Previous studies found that post-stress LVEF and post-stress ESV assessed during gated SPECT had incremental predictive value in predicting cardiac death. In part, normal myocardial perfusion imaging was associated with a very low likelihood of cardiac death or myocardial infarction.…”

“…Cardiac events within 60 days after nuclear testing (n=375) were censored from the prognostic portion of the analysis. 20,23 …”

Clinical usefulness of novel cardiac MDCT/SPECT fusion image

“…The evaluation for known or suspected CAD using ECG-gated SPECT imaging has been established for its diagnosis and risk assessment [18][19][20]. It is a well-known fact that a comprehensive assessment of CAD requires not only morphologic information about coronary stenosis location and degree but also functional information [21][22].…”

The relationship between stress-induced myocardial ischemia and coronary artery atherosclerosis measured by hybrid SPECT/CT camera

“…Nuclear cardiology techniques are uniquely advanced to address the determinants of prognosis by measuring stressinduced ischemia or function. These measurements include the extent of infracted myocardium and the amount of jeopardized myocardium [4].…”
