Researchers find predictor of mortality in cardiac patients
February 21, 2007
Researchers at SUNY Downstate Medical Center in Brooklyn have determined that low levels of a protein in the blood is a predictor of cardiac death in patients with coronary artery disease. In a group of men undergoing coronary angiography, low baseline levels of RANTES (Regulated upon Activation, Normal T-cell Expressed, and Secreted), also known as CCL5, were shown to be an independent predictor of cardiac mortality.
RANTES is a chemokine produced by a variety of cell types including blood platelets that has been implicated in atherosclerosis. Chemokines are naturally occuring human proteins that signal white blood cells to move in a specific direction, such as to an infection site.
Erdal Cavusoglu, MD, assistant professor of medicine at SUNY Downstate, and colleagues measured baseline RANTES levels in 389 male patients at a Veterans Affairs medical center. The patients were followed prospectively for the occurrence of cardiac mortality and myocardial infarction (heart attack). Results showed that patients with the lowest level of RANTES had the lowest survival rate, and those with the highest levels had the highest survival rates. This was also true for the diabetic subset of patients in the study.
The authors propose several potential explanations for this somewhat paradoxical observation, including potential upregulation of the RANTES receptor, the CCR5 receptor, which is known for its proatherosclerotic properties. Alternatively, lower levels of RANTES may simply reflect greater deposition of RANTES on atherosclerotic arteries with less circulating levels available for measurement by routine ELISA testing.

The heart attack myth: Study establishes that women do have same the heart attack symptoms as men The gender difference between men and women is a lot smaller than we've been led to believe when it comes to heart attack symptoms.
Comprehensive cardiac CT scan may give clearer picture of significant heart disease A team of researchers led by Massachusetts General Hospital (MGH) radiologists has developed a computed-tomography-based protocol that identifies both narrowing of coronary arteries and areas of myocardial ischemia - restricted blood flow to heart muscle tissue - giving a better indication of clinically significant coronary artery disease.
Study in NEJM: New therapy prevents heart failure Patients who had a cardiac resynchronization device combined with a defibrillator (CRT-D) implanted had a 34 percent reduction in their risk of death or heart failure when compared to patients receiving only an implanted cardiac defibrillator (ICD).
Electronic health records help cardiac patients remain healthy An innovative program that cut cardiac deaths by 73 percent by linking coronary artery disease patients and teams of pharmacists, nurses, primary care doctors, and cardiologists with an electronic health record also kept the patients healthy two years after they left the program by keeping them in touch with their care givers electronically.
Blood transfusion study: Less is more A new study suggests that blood transfusions for hospitalized cardiac patients should be a last resort because they double the risk of infection and increase by four times the risk of death.
Cardiac rehabilitation saves lives Coronary heart disease (CHD) is the leading cause of death worldwide and a major driver of medical and economic costs, especially among older adults.
Genetic factors may predict depression in heart disease patients Individuals with heart disease are twice as likely to suffer from depression as the general population, an association the medical community has largely been unable to explain.
Walking often and far reduces risks in heart patients An exercise program that burns a lot of calories reduced cardiac risk factors better than standard cardiac rehabilitation in overweight coronary patients, researchers report in Circulation: Journal of the American Heart Association.
ESC reaffirms advice on cardiovascular risks associated with long-haul flights Dr Steen Kristensen, Vice-president of the ESC, says: "Long distance flying is associated with an increase in deep venous thrombosis, which in some cases may lead to clotting of the lungs. People who are immobile, pregnant, taking contraceptive pills or have had venous thrombosis in the past are particularly at risk.

The Virtual Cardiac Patient: A Multimedia Guide to Heart Sounds and Murmurs
by Jonathan Keroes (Author), David Lieberman (Author)
This multimedia CD-ROM is a convenient, accessible tool for developing cardiac auscultation skills. It contains computer simulations of 28 abnormal heart sounds along with visual representations of the sounds (phonocardiograms), electrocardiograms and pressure tracings for each condition, and animated cartoons showing the anatomic and Doppler flow abnormalities. Users can listen to each auditory heart sound while viewing graphic material that helps identify the abnormality. On-screen controls allow users to selectively listen to portions of the heart sound cycle--S1, S2, systole, or diastole. The program also includes a quiz mode. When using this CD-ROM headphones are required. Windows / Macintosh Compatible

Psychotherapy With Cardiac Patients: Behavioral Cardiology in Practice
by Ellen A. Dornelas (Author)
Heart disease is the leading cause of the death in the United States, and those who experience cardiac events suffer a wide range of psychological sequelae. Yet, few books show psychotherapy practitioners how they can modify their techniques to accommodate the unique needs of this population.
In this book, the author, an experienced hospital-based psychologist, provides an orientation to this specialization and, drawing on a variety of therapy models, describes empirically-supported intervention strategies. After providing an overview of the cardiovascular system, she discusses lifestyle and psychological risk factors for heart disease. Subsequent chapters cover practical techniques for helping patients overcome depression, anxiety, and hostility, all factors that complicate...
