SCAI Hildner Lecture highlights innovative techniques for plaque imaging

15.05.2006


Finding and treating vulnerable plaque early could prevent heart attack and death

Virtual histology. Thermography. Palpography. Computed tomography. Today, during the Society for Cardiovascular Angiography and Interventions (SCAI) 29th Annual Scientific Sessions in Chicago, Dr. Gregg W. Stone will explore these and other promising imaging techniques in a featured Hildner Lecture entitled, "Prospects for the Invasive and Non-Invasive Identification of Vulnerable Plaque."

"Approximately every 34 seconds, someone in the United States dies of cardiovascular disease," said Dr. Stone, a professor of medicine at Columbia University, director of cardiovascular research and education at the Center for Interventional Vascular Therapy, and vice-chairman of the Cardiovascular Research Foundation, all in New York City. "Most people who have a heart attack have no warning whatsoever."

Fragile, thin-capped coronary plaques cause most heart attacks. When they burst, a blood clot blocks the artery and cuts off blood flow to the heart. Many patients have never had a minute’s chest pain before the heart attack strikes. What’s worse, vulnerable plaques cannot be detected with conventional imaging techniques, such as angiography.

"If we can see the vulnerable plaque, we can treat it--before it ruptures and causes a heart attack and death," said Dr. Stone, who is also a Trustee of SCAI.

Researchers are testing and refining an array of innovative techniques for detecting vulnerable plaque. Among noninvasive methods, multislice computed tomography is generating the greatest excitement today. Easy to use and available in every major medical center, high-end CT scanners create colorful and detailed pictures of the coronary arteries.

Invasive techniques are more complicated and time-consuming to use--they require threading a catheter into the arteries of the heart--but they have the potential to provide a wealth of anatomic and functional information. For example, virtual histology uses intravascular ultrasound to re-create a picture of the plaque, whereas optical computed tomography uses light to define its structure. Thermography relies on differences in temperature to identify inflamed, vulnerable plaque, while spectroscopy defines its chemical composition, and palpography measures stress on the plaque’s thin, fragile cap.

Studies are under way to determine which, if any, of these techniques can best detect and characterize vulnerable plaque. If the studies are positive, plaque imaging could help tens of millions of people with undiagnosed coronary artery disease.

"These techniques could have major societal implications," Dr. Stone said. "Everyone who is prone to cardiovascular disease--virtually all middle-aged and elderly men and postmenopausal women--could benefit from early detection and treatment."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
