چکیده
A common question we are asked when informing patients about a PET scan is “Will it show the percentage of my artery that is blocked?” This question has triggered the following discussion about the importance of coronary blood flow rather than percent stenosis when checking on the status of the coronary arteries. The previous issue of PET News introduced readers to Non-invasive imaging of the heart and explained: (1) the differences in anatomic imaging vs. functional imaging of the heart (2) the technical problems with Computed Tomography (CT) and (3) how PET accurately shows a change in blood flow to the heart that is proportionately larger than small unmeasurable anatomic changes in percent stenosis. Since the essential medical problem of coronary heart disease is blood flow in the heart muscle, PET is the best way of identifying or assessing severity of coronary disease and for following progression or regression of coronary artery disease before a coronary emergency. This article reports further on imaging techniques commonly used in Cardiology practice today and then focuses on new developments in PET imaging for measuring coronary blood flow. Background information is reviewed that is the basis for an ongoing major shift in managing CAD that is starting to develop as evidenced by numerous recent scientific publications.

Increasing evidence from epidemiological, clinical, and basic mechanistic studies supports the importance of HDL in preventing or even reversing atherosclerosis. The well-known structural and compositional diversity of HDL subfractions seems to be an important, if still somewhat unclear, factor in the atheroprotective potential of a given HDL particle. Perhaps as important as the parameter of p...

There is growing interest in flavonoids for their wide array of biological actions. In neurodegenerative disorders these naturally occurring polyphenolic compounds, are known to inhibit proinflammatory mediators such as in TNF–? and IL-6 in lipopolysaccharide (LPS) stimulated neuronal degeneration, which are associated with Alzheimer’s and Parkinson’s disease. Recent studies on flavonoids have ...

Cytomegalovirus (CMV) infection is one of the most common infections that affects humans’ cardiovascular system. Although the literature includes controversial evidence for any correlation between CMV infection and arterial atherosclerosis, the majority of studies, especially those with larger patient population and stronger data stand for such a relationship. However, the number of prospective...
