Universality in quantum measurements
We briefly review a number of major features of the approach to quantum measurement theory based on environment-induced decoherence of the measuring apparatus, and summarise our observations in the form of a c...

Open AccessDuration of type 2 diabetes mellitus and systolic blood pressure as determinants of severity of coronary stenosis and adverse events in an asymptomatic diabetic population: PROCEED study
Evidence from imaging studies suggests a high prevalence of coronary artery disease (CAD) in patients with type 2 diabetes mellitus (T2DM). However, there are no criteria for initiating screening for CAD in th...

Evaluation of graft patency by computed tomographic angiography in symptom-free post-coronary artery bypass surgery patients
Accelerated atherosclerosis occurs in aortocoronary saphenous vein grafts, contributing to increased morbidity and mortality rates. We estimated the prevalence of asymptomatic graft failure in patients 5 years...

Comparison between Tc-99m N-NOET and Tl-201 in the assessment of patients with known or suspected coronary artery disease
Technetium 99m N-ethoxy-N-ethyl dithiocarbamate (N-NOET) is a new radionuclide tracer for cardiac single photon emission computed tomography (SPECT) imaging. It combines the advantageous properties of a Tc-99m...

Should we be screening for myocardial hibernation in heart failure?
To summarize, myocardium can exist in a functionally dormant but still viable state. The CHRISTMAS trial showed that the quantity of viable myocardium is likely to govern response to medical therapy (β-blocker...

Impact of revascularization and myocardial viability determined by nitrate-enhanced Tc-99m sestamibi and Tl-201 imaging on mortality and functional outcome in ischemic cardiomyopathy
Nitrate-enhanced perfusion imaging has been shown to detect viability in dysfunctional myocardium, but nitrate-enhanced technetium 99m sestamibi has not been compared with nitrate-enhanced thallium 201.
