Study: 28.8% of CAD patients who fails to undergo complete revascularization face higher mortality rate

A 3-year, retrospective study by cardiologists from the Minneapolis Heart Institute Foundation and the University of Minnesota determined that 28.8% of patients with significant coronary artery disease who did not undergo complete revascularization had a higher mortality rate than patients completely revascularized.

Advances in understanding of cardiac-specific genes in heart development

Researchers at the Texas Heart Institute at St. Luke's Episcopal Hospital (THI at St. Luke's) announced today the results of research which they believe marks a significant advance in understanding how cardiac-specific genes are turned on during the development of the heart in mice embryos.

Real-people videos and expert advice to address childhood obesity

More than anything, bad habits are to blame for the childhood obesity epidemic. For Alejandra and her parents, food was an expression of love. But overeating and other unhealthy habits led this 11-year-old Hispanic girl to become an overweight kid.

Coronary CTA can be alternative, non-invasive diagnostic imaging test to triage CAD patients: Study

Non-invasive coronary computed tomography angiography is a cost-effective alternative to invasive cardiac catheterization in the care of patients who have positive stress test results but a less than 50 percent chance of actually having significant coronary artery disease, according to a study in the May issue of the American Journal of Roentgenology.

New blood test to determine patients at low risk for rejection of transplanted hearts

After his heart transplant in 2005, Ramon Llenado underwent a biopsy every week, then every month, then every three months. Most heart transplant patients face a lifetime of these invasive tests, which involve snipping out tiny pieces of heart to check for possible organ rejection.

New on-off switches: SUMO protein silences developmental genes, SNP2 snips SUMO to allow gene expression

Deleting a gene in mouse embryos caused cardiac defects and early death, leading researchers to identify a mechanism that turns developmental genes off and on as an embryo matures, a team led by a scientist at The University of Texas M. D. Anderson Cancer Center reported today in Molecular Cell.

Researchers take major step to predict adverse drug reactions using genetic information

In a new study, researchers at Mount Sinai School of Medicine have taken a major step toward the ability to predict adverse drug reactions, using genetic, cellular, and clinical information to learn why some medicines cause heart arrhythmias in patients. Published in the April 20 issue of the journal Science Signaling, the new framework described in the study could potentially be applied to the study of medications that treat other diseases and disorders such as epilepsy and autism.

Research associates diabetes with atrial fibrillation

As the U.S. population keeps aging and gaining weight, diabetes is becoming increasingly common. Some research has associated diabetes with the most common kind of chronically irregular heartbeat, called atrial fibrillation, which can raise the risk for stroke and death. But results of past studies of diabetes and atrial fibrillation have conflicted.

Techniques to protect organs during bypass surgery impair autoregulation, increase risk of stroke: Study

The standard practice of cooling and then rewarming a patient to prevent organ damage during cardiac bypass surgery may impair the body's mechanism that controls blood flow to the brain, potentially increasing the patient's risk of stroke, new research from Johns Hopkins suggests.

Interesting heart rate dynamics in premature infants

A normal healthy heart beats at a variable rate with extraordinarily complex fluctuations across a wide range of time scales. Reduced complexity of heart rate has both clinical and dynamical significance - it may provide warning of impending illness, or clues about the dynamics of the heart's pacemaking system.

Hospitals striving to provide balloon angioplasties in under 60 minutes for patients undergoing heart attacks

National guidelines say patients undergoing heart attacks should receive balloon angioplasties as soon as possible or within 90 minutes of arriving at the hospital -- known as the "door-to-balloon time."

Researchers produce stem cells from eggs of aging mice for regenerative medicine

Researchers at NYU Langone Medical Center have created stem cells from the eggs of aging mice that could be used for reproductive purposes and regenerative medicine. The study, published in April issue of Aging Cell, found that even though the eggs from older females were slightly less efficient at making stem cells than those from younger females, the capacity to create stem cells was sustained.

Researchers to measure children with Down syndrome to develop new growth charts

Parents and doctors have known for a long time that children with Down syndrome tend to grow more slowly and are considerably shorter than most other children. But pediatricians needing to record growth milestones at regular office visits have an outdated set of growth charts based on data collected more than 25 years ago.

Gelesis presents Attiva data at AACE 19th Annual Meeting & Clinical Congress

Boston-based medical technology firm Gelesis, Inc. unveiled its capsulated device Attiva™, and presented data showing that Attiva™ significantly increased the post-meal feeling of satiety and reduced hunger between meals in obese patients. This data was presented today at the American Association of Clinical Endocrinologists (AACE) 19th Annual Meeting & Clinical Congress.

Genetic tests that may replace biopsies

Genetic tests conducted on blood samples may replace the current biopsies when it comes to checking if immune systems are rejecting new organs of heart transplant patients. The test would be far less invasive and uncomfortable as compared to the biopsies, not to mention more affordable.

AB SCIEX to collaborate in disease studies with Samuel Lunenfeld Research Institute of Mount Sinai Hospital

AB SCIEX, a global leader in life science analytical technologies, today announced that it is collaborating with the Samuel Lunenfeld Research Institute of Mount Sinai Hospital, one of the world's leading centers for biomedical research, to improve disease studies. The project is focused on better understanding cancer, diabetes and heart disease by advancing the study of proteins through the use of an emerging mass spectrometry platform currently under development by AB SCIEX.

IL-10 Gene Therapy helps repair damaged lungs found unfit for transplant

Promising research brings hope for the almost two thousand lung transplant candidates who currently make up The United Network for Organ Sharing's (UNOS) wait list. A new technique that uses gene therapy to help repair damaged lungs previously found unfit for transplant shows promise for addressing the critical shortage of healthy donor organs.
