Coronary aneurysms are independent predictor of mortality, should be aggressively monitored

09.03.2004


The results of a study presented today at the American College of Cardiology’s 53rd Scientific Sessions in New Orleans concludes that coronary aneurysms -- regardless of size -- are associated with a increased risk of death over a five year period and should be aggressively monitored.



The University of Chicago Hospitals and Emory Heart Center researchers studied the records of 32,372 patients undergoing coronary angiography at Emory University Hospitals in Atlanta between 1995 and 2003 and identified 276 with coronary artery aneurysms (abnormal enlargement or bulging of arteries) .The presence of an aneurysm of any size was found to have an adverse effect on long-term mortality similar to diabetes, coronary artery disease (CAD) and high cholesterol levels. "The results also show that no single risk factor -- CAD, hypertension, hyperlipidemia, diabetes, sex, or age -- was associated with the size of an aneurysm," says Emory Heart Center cardiologist Laurence S. Sperling, MD, co-author of the study. Other study authors are Timir S. Baman, MD; Jason H. Cole, MD; and Chandan M. Devireddy, MD.

"In addition, we found these patients have a predicted 5-year mortality rate of 29.1% -- a figure that is somewhat troubling, especially with the marked improvement in medical technology over recent years," Dr. Sperling, Director of Preventive Cardiology at Emory, adds. "In light of these findings, we believe all patients with angiographic evidence of coronary aneurysms should receive aggressive modification of coronary risk factors -- whether or not serious coronary disease is present. This research shows that clinicians should take all coronary aneurysms, regardless of size, seriously and monitor them aggressively."



Emory Heart Center is comprised of all cardiac services and research at Emory University Hospital, Emory Crawford Long Hospital Carlyle Fraser Heart Center, the Andreas Gruentzig Cardiovascular Center of Emory University and the Emory Clinic. Ranked among the nation’s top ten heart centers by U.S. News & World Report’s annual survey, the Emory Heart Center has a rich history of excellence in all areas of cardiology and cardiac surgery --including education, research and patient care. It is internationally recognized as one of the birthplaces of modern interventional cardiology and was the site of the first coronary stent implantation in the United States, the only single site randomized comparison of angioplasty and bypass surgery and pioneering work in vascular brachytherapy.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
