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: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
