Emory data suggest diabetics have worsening symptoms prior to acute cardiac event

10.11.2003


New data presented by Emory researchers at the American Heart Association’s Scientific Sessions abstract poster sessions today address angina related quality of life in diabetic and non-diabetic patients undergoing percutaneous coronary intervention (PCI), medical procedures performed in catheterization laboratories to reduce the amount of narrowing in a coronary artery due to plaque formation.



According to Emory Heart Center cardiologist William Weintraub, M.D. FACC, who headed the research team, people with diabetes are two to four times more likely to develop cardiovascular disease due to a variety of risk factors. They are also more likely to undergo PCI. "However, the impact of cardiac symptoms on quality of life in diabetics with PCI has not been systematically analyzed before," says Dr. Weintraub, who is Director of the Emory Center for Outcomes Research.

The Emory University Division of Cardiology, School of Medicine and School of Nursing researchers studied patients undergoing PCI on a non-emergency basis at Emory University Hospital in Atlanta over a five month period. The research subjects completed the Seattle Angina Questionnaire (SAQ), which measures angina-related quality of life, and scores were compared to those of non-diabetics. Other variables, including gender, age, race, prior revascularization, smoking status, hypertension, renal function, lipid levels, medications, and anatomy were collected.


Tests were also conducted to see which patients met the criteria for a non-Q-wave myocardial infarction (NQWMI). A NQWMI is a heart attack caused by a ruptured plaque in a coronary artery and a resulting blood clot that is usually non-occlusive, typically causing less damage to the heart muscle . Levels of troponin, an enzyme found only in heart muscle tissue that can reveal heart attacks that might not show up definitively on other tests such as an EKG, were measured to determine whether or not an NQWMI had occurred.

"We found that diabetics presenting for elective angioplasty do not differ significantly from non-diabetics in their angina-specific quality of life. However, in those who have experienced a NQWMI, diabetes predicts greater physical limitation even though although angina stability and frequency did not differ," says Dr. Weintraub. "This is an important finding because it could indicate that diabetics have had worsening symptoms and disability prior to the acute event."


The Emory Heart Center is comprised of all cardiology services and research at Emory University Hospital (EUH), Emory Crawford Long Hospital (ECLH) Carlyle Fraser Heart Center, the Andreas Gruentzig Cardiovascular Center of Emory University and the Emory Clinic. Ranked in the top ten of U.S. News & World Report’s annual survey of the nation’s best Heart Centers, the Emory Heart Center has a rich history of excellence in all areas of cardiology - including education, research and patient care. It is also internationally recognized as one of the birthplaces of modern interventional cardiology.

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...
