Researchers identify new genetic regions associated with heart attacks

In the largest genetic study of Coronary Artery Disease (CAD) to date, researchers from the CARDIoGRAMplusC4D Consortium report the identification of 15 genetic regions newly associated with the disease, bringing to 46 the number of regions associated with CAD risk.

Innovative stem cell technique for heart tissue revealed

Researchers have found that stem cell cultures infused with growth factors could be used to repair damaged heart tissue without the threat of patient rejection.

FDA approves Velomedix’s IDE to expand design of VELOCITY trial for heart attack

Velomedix, Inc., a venture-backed medical device company advancing the field of therapeutic hypothermia, announced it has received Investigational Device Exemption (IDE) approval from the U.S. Food and Drug Administration (FDA) to expand the design of its VELOCITY pilot clinical trial.

Intramyocardial injection of organ-derived stem cells after AMI improves left ventricle function

A study published in the current issue of Cell Transplantation, now freely available on-line, has found that when mesenchymal cells derived from skeletal muscle (SM-MSCs) or adipose tissue (ADSCs) were injected into the heart muscle (myocardium) of separate groups of laboratory rats that had suffered a myocardial infarction, rats in both groups experienced significantly improved left ventricle function and smaller infarct size after cell therapy.

Arginase might play a role in development of cardiovascular disease in type II diabetics

In a new study published in the scientific journal Circulation, scientists at Karolinska Institutet and Karolinska University Hospital in Sweden show that an enzyme called arginase might have a key part to play in the development of cardiovascular disease in patients who already have type II diabetes.

Lack of job may raise heart attack risk

Unemployment, multiple job losses, and short periods without work are all significant risk factors for acute myocardial infarction, say researchers.

Study shows how MCUR1 protein helps regulate movement of calcium into mitochondria

A team of scientists from Temple University School of Medicine and the University of Pennsylvania has moved another step closer to solving a decades-long mystery of how the all-important flow of calcium into the cell's power source, the mitochondria, is controlled.

Treatment-related heart failure risk for rheumatoid arthritis patients revealed

Rheumatoid arthritis patients have no greater risk for heart failure with tumor necrosis factor-alpha therapy than with nonbiologic disease-modifying antirheumatic drugs, research suggests.

Cinacalcet failure raises trial conduct issues

The oral calcimimetic agent, cinacalcet, has been found to have no significant effect on cardiovascular events or death in patients with chronic kidney disease in a randomized controlled trial.

HUCPVC cell therapy more effective in restoring heart function after myocardial infarction

A study published this month by researchers at the University of Toronto and Toronto's Princess Margaret Hospital has shown that cells derived from the umbilical cord, "Human Umbilical Cord PeriVascular Cells" (HUCPVCs), are more effective in restoring heart function after an acute myocardial infarction (in common parlance, a heart attack) in a pre-clinical model than a similar cell population derived from bone marrow.

Dialysis raises complication, mortality risk after general surgery

Long-term dialysis patients undergoing general surgical procedures have a significantly increased risk for postoperative complications and death within 30 days of surgery compared with their nondialysis counterparts, study findings show.

Antibody-coated stents carry increased risk of myocardial infarction and re-operation

If narrowed or blocked coronary vessels have to be widened or opened, a vascular support (stent) is usually inserted. Drug-coated stents are preferred for patients at high risk of renewed narrowing of vessels (restenosis). However, the use of antibody-coated stents has been increasing in recent years. Current studies provide indications that these new antibody-coated stents more frequently lead to myocardial infarction and make re-operation necessary.

Anesthetic choice may not be critical in noncardiac surgery

The choice of general anesthetic does not appear to influence the risk for myocardial infarction in patients undergoing noncardiac surgery, report researchers.

Psychiatric patients not ‘down-triaged’ in the ED

Study findings refute the belief that patients with psychiatric illness may wait longer than is appropriate to see a doctor in the emergency department.

GW Hospital, The Wireless Foundation announce new initiative to improve cardiac care

Today, the George Washington University Heart and Vascular Institute and The Wireless Foundation, in partnership with the D.C. Fire and Emergency Medical Services, announced their innovative public health initiative, which will improve cardiac care in the nation's capital.
