Diabetes mellitus-associated coronary artery disease (CAD) is assuming epidemic proportions, especially in western countries. Both coronary revascularization and medical management have improved tremendously over the last decade and the respective role in the diabetic population is not well defined. This aspect was investigated in the BARI 2D study*. http://www.physorg.com/news170942254.html Medicine & Health Mon, 31 Aug 2009 17:00:02 EST news170942254 At present almost every month there are papers reporting the discovery of new genetic variants that affect the risk of coronary artery disease and heart attacks. This is a truly exciting time for both researchers and clinicians interested in understanding the genetic basis of heart disease. The findings will undoubtedly lead to new biological insights into the mechanisms that cause heart attacks which in turn may result in the future new types of treatments. Will this new genetic information be useful in preventing heart attacks and if so how? http://www.physorg.com/news170937677.html Medicine & Health Mon, 31 Aug 2009 11:41:47 EST news170937677 (PhysOrg.com) -- Men with angina are twice as likely to have a heart attack and almost three times as likely to suffer a heart disease-related death than women with the same condition, finds a study published on bmj.com today (August 7). http://www.physorg.com/news168867652.html Medicine & Health Fri, 07 Aug 2009 13:00:01 EST news168867652 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, according to a randomized study by Kaiser Permanente published in The American Journal of Managed Care this month. http://www.physorg.com/news168858641.html Medicine & Health Fri, 07 Aug 2009 10:50:01 EST news168858641 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. http://www.physorg.com/news168696993.html Medicine & Health Wed, 05 Aug 2009 13:17:00 EST news168696993 A novel class of drugs composed of single strands of DNA or RNA, called aptamers, can bind protein targets with a high strength and specificity and are currently in clinical development as treatments for a broad range of common diseases, as described in a comprehensive review article published online ahead of print in Oligonucleotides, a peer-reviewed journal published by Mary Ann Liebert, Inc. http://www.physorg.com/news168696592.html Chemistry Wed, 05 Aug 2009 13:10:36 EST news168696592 Heart disease patients with previous atherosclerosis (fat deposits in the walls of the arteries) are more likely to die in the hospital and less likely to be treated with recommended therapies, researchers report in Circulation: Journal of the American Heart Association. http://www.physorg.com/news168540891.html Medicine & Health Mon, 03 Aug 2009 18:40:01 EST news168540891 Major depression and coronary artery disease are only modestly related throughout an individual's lifetime, but studying how the two interact over time and in twin pairs paints a more complex picture of the associations between the conditions, according to a report in the August issue of Archives of General Psychiatry.

Coronary artery disease (CAD) is prevalent in patients with PAD and it is known that PAD is under diagnosed in the primary care setting, but a new study found that it is often overlooked even in patients with known heart disease who are under a cardiologist's care. The study was published in the May issue of Catheterization and Cardiovascular Interventions, the official journal of The Society for Cardiovascular Angiography and Interventions (SCAI). http://www.physorg.com/news160141605.html Medicine & Health Tue, 28 Apr 2009 12:47:45 EST news160141605 Sometimes cardiologists and cardiac surgeons can agree!
