Biomedical engineers grow 3D human heart muscle that acts just like natural tissue

Duke University biomedical engineers have grown three-dimensional human heart muscle that acts just like natural tissue. This advancement could be important in treating heart attack patients or in serving as a platform for testing new heart disease medicines.

Study: Stem cells can communicate with mature heart cells, form electrical couplings

Stem cells drawn from amniotic fluid show promise for tissue engineering, but it's important to know what they can and cannot do. A new study by researchers at Rice University and Texas Children's Hospital has shown that these stem cells can communicate with mature heart cells and form electrical couplings with each other similar to those found in heart tissue.

Regional anesthesia improves outcomes in sleep apnea patients undergoing total joint arthroplasty

Using regional anesthesia instead of general anesthesia in patients with sleep apnea undergoing total joint replacement decreases major complications by 17%, according to a study published online, ahead of print, in the journal Regional Anesthesia and Pain Medicine.

Five sudden signs and symptoms of stroke

Stroke is the fourth-leading cause of death in the United States. Each year an estimated 795,000 people in this country experience a stroke. That's approximately the equivalent of every man, woman and child living in Anaheim and Long Beach combined.

Increased accumulation of coronary artery calcium leads to heart attack risk

Patients with increasing accumulations of coronary artery calcium were more than six times more likely to suffer from a heart attack or die from heart disease than patients who didn't have increasing accumulations, according to a recent study published in the Journal of the American College of Cardiology.

Lowering door-to-balloon times helps benefit STEMI patients, study finds

While all heart attacks have the potential to be deadly, one type is referred to as the "widow maker" because of its high risk of death. A ST segment elevation myocardial infarction is a severe type of heart attack that occurs when a blockage in a coronary artery causes heart muscle to die; without prompt treatment risk of fatality increases dramatically. Coronary angioplasty, or percutaneous coronary intervention, is the most common emergency treatment for STEMI.

Molecular pathway that helps form new arteries after heart attacks uncovered

Scientific collaborators from Yale School of Medicine and University College London have uncovered the molecular pathway by which new arteries may form after heart attacks, strokes and other acute illnesses bypassing arteries that are blocked.

Naturopathic lifestyle counselling helps reduce risk of cardiovascular disease

Counselling and treatment with naturopathic care as well as enhanced usual care reduced the prevalence of metabolic syndrome, a risk factor for heart disease, by 17% over a year for participants in a randomized controlled trial published in CMAJ.

Bioengineers use highly elastic micropatterned gels to create heart tissue

A team of bioengineers at Brigham and Women's Hospital is the first to report creating artificial heart tissue that closely mimics the functions of natural heart tissue through the use of human-based materials.

Serum C-peptide levels predict cardiovascular death risk

Levels of C-peptide predict the risk for death from cardiovascular disease in nondiabetic adults, show data from the US National Health and Nutrition Examination Survey.

Omega-3 polyunsaturated fatty acids associated with lower risk of heart failure mortality in adults

Omega-3 polyunsaturated fatty acids, namely DHA and EPA found in fatty fish, are associated with lower risk of heart failure mortality in adults with chronic heart failure or who have experienced a heart attack.

Higher TMAO blood levels linked to increased risk of heart disease

A microbial byproduct of intestinal bacteria contributes to heart disease and serves as an accurate screening tool for predicting future risks of heart attack, stroke and death in persons not otherwise identified by traditional risk factors and blood tests, according to Cleveland Clinic research published today in The New England Journal of Medicine.

Researchers studying lipids to learn more about normal, abnormal biology

When you have your cholesterol checked, the doctor typically gives you levels of three fats found in the blood: LDL, HDL and triglycerides. But did you know your body contains thousands of other types of fats, or lipids?

Frequent binge drinking in college increases risk of cardiovascular disease later in life

Frequent binge drinking in college can cause more than a hangover. Regularly consuming multiple drinks in a short window of time can cause immediate changes in circulation that increase an otherwise healthy young adult's risk of developing cardiovascular disease later in life, according to research published online today in the Journal of the American College of Cardiology.

Study: About 42% of screened veterans with blast injuries have irregular hormone levels

Up to 20 percent of veterans returning from Afghanistan and Iraq have experienced at least one blast concussion. New research suggests that nearly half these veterans may have a problem so under-recognized that even military physicians may fail to look for it.

Two studies examine safety of nitrous oxide for surgical anesthesia

Giving nitrous oxide as part of general anesthesia for noncardiac surgery doesn't increase the rate of complications and death—and might even decrease the risk of such events, according to a pair of studies in the May issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society.

Despite public health efforts, sodium intake continues to rise.

Sodium intake around the world is well in excess of physiological needs and public health authorities agree that chronic excess sodium intake can increase blood pressure and the risk of heart attack and stroke. However, despite recommendations to lower sodium consumption over the last decade, actual intake continues to rise.

DecImmune and DSM to develop proprietary antibody therapeutic

DSM Pharmaceutical Products, the custom manufacturing and technology business of Royal DSM (NYSE, Euronext: DSM KON), announced today that it has signed an agreement with venture capital funded DecImmune Therapeutics of Cambridge, Massachusetts, USA.

New data on safety of nitrous oxide as surgical anesthetic

Giving nitrous oxide as part of general anesthesia for noncardiac surgery doesn't increase the rate of complications and death-and might even decrease the risk of such events, according to a pair of studies in the May issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

Taking painkillers before race leads to unrecognised problems

Many competitors try to prevent pain interfering with their performance by taking painkillers that are readily available in pharmacies and supermarkets, say the authors.
