Noninvasive evaluation of ischaemic heart disease: myocardial perfusion imaging or stress echocardiography?

Resting 12-lead electrocardiogram as a reliable predictor of functional recovery after recanalization of chronic total coronary occlusions

“…4,20,21 However, only 50-80% of viable myocardium detected by different imaging techniques do in fact recover after revascularization. 8 The discrepancy of our results with the aforementioned studies could be explained as follows: First, those studies proved viability and recovery of ventricular function in patients with diseased, but not chronically occluded coronary arteries. Only one study investigated functional recovery of hibernating myocardium in patients with CTO, but without Q-wave MI.…”

“…All these techniques have a sensitivity of 81 to 93% and a moderate specificity of 50 to 80% for contractile recovery. 8 Therefore, and because of the costly and time-consuming nature of these imaging techniques, inexpensive methods of similar accuracy would be desirable.…”

The value of contrast dobutamine stress echocardiography in detecting coronary artery disease in overweight and obese patients

“…Pooling of the data showed a slightly higher overall sensitivity for SPECT perfusion imaging compared with stress echocardiography (84% versus 80%, P<0.05). On the other hand, stress echocardiography was more specific than perfusion imaging (86% versus 77%, P=0.001) (19). In our study, the diagnostic value for the detection of CAD was comparable with that of SPECT.…”

Accuracy of Stress Myocardial Perfusion Imaging to Diagnose Coronary Artery Disease in End Stage Liver Disease Patients

“…In contrast, in select groups of patients who are being evaluated for ischemic heart disease, myocardial perfusion imaging is reported to have higher sensitivity of 84% and specificity of 77% for identifying patients with 50% diameter stenosis. 19 Fractional flow reserve is more accurate than coronary angiography to assess the physiologic significance of a stenosis, and in the current era, fractional flow reserve is the gold standard for diagnosing the significance of CAD. 20,21 Our results of 473 radionuclide pharmaceutical stress tests in patients with ESLD suggest that a standard risk factor assessment provides results that are equivalent to those of radionuclide imaging studies.…”
