Duke engineers develop new 3-D cardiac imaging probe

Biomedical engineers at Duke University's Pratt School of Engineering have created a new three-dimensional ultrasound cardiac imaging probe. Inserted inside the esophagus, the probe creates a picture of the whole heart in the time it takes for current ultrasound technology to image a single heart cross section. The new probe has considerable potential not only for evaluating the condition...

Mouse gene shows new mechanism behind cardiac infarction in man

A gene that, in different variants, increases or decreases the level of atherosclerosis has been identified in mice. The corresponding human gene has been shown to play a role in the development of myocardial infarction. Researchers at Karolinska Institutet, in collaboration with the Jackson Laboratory in th...

Researchers Find Drug May Give Some Cardiac Protection 24 Hours After Heart Attack

A drug has been shown to provide some protection to the heart from injury even if given as much as 24 hours after a heart attack, Jefferson Medical College researchers report. Walter Koch, Ph.D., director of the Center for Translational Medicine in the Department of Medicine at Jefferson Medical College of Thomas Jefferson University in Philadelphia, and his co-workers knew that the drug D...

Man-made heart tissue improves cardiac performance

Researchers have developed a method to engineer blood vessels within the tissue of previously engineered heart muscle. Trials have resulted in significant improvement in heart function. The study is published in the journal Artificial Organs. With heart disorders affecting individuals globally and contributing to increasing mortality rates, there has been a need to develop new treatmen...

U of MN uses robotic surgery techniques in cardiac cell therapy research

Researchers at the University of Minnesota were successful in using robotic surgery to deliver stem cell treatment to damaged heart tissue in pigs. <...

Even a little cooling helps after cardiac arrest

Is that salt marsh healthy? To answer this, Sea Grant biologists are cracking open common marsh snails and counting parasitic worms. Their claim: the more parasites, the healthier the marsh. While the parasite hypothesis may conflict with conventional ideas about infectious disease and human health (malaria, for example, is caused by a parasite), the worms the scientists are investigating...

Clot-busting drug helps revive cardiac arrest patients

Using a "clot buster" drug normally reserved for treating patients during a heart attack, emergency room doctors were able to double the number of patients who could be revived from cardiac arrest. This sudden loss of heart function occurs in more than 260,000 people a year nationwide ?and at least 93 percent of them die. "Clot-busting agents show promise as a new therapy for this abrupt a...

Twin studies reveal genetic components leading to cardiac and kidney disease

Daniel O’Connor, M.D., Professor of Medicine and Pharmacology at the University of California, San Diego (UCSD) School of Medicine has studied about 265 twin pairs over the past few years, which has led him to some surprising discoveries. Studying genetic variations in twins provides...
