Clinical study shows association between Corus CAD blood test scores and cardiovascular event rates

CardioDx, Inc., a molecular diagnostics company specializing in cardiovascular genomics, announced today results from a genomic substudy of the NHLBI-funded Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) trial in nondiabetic patients receiving the Corus CAD blood test.

Study evaluates long-term outcomes of TAVR with SAPIEN 3 in intermediate-risk patients

To account for baseline differences, TAVR patients were compared by a propensity score analysis with patients randomized to receive surgical intervention in a precursor study, PARTNER 2A. Propensity scoring analysis is a statistical technique used to reduce bias from potential confounding variables, which in this case was used to identify surgical patients from a previous study who would be comparable to TAVR patients in this study.

Frequent TAVR to replace damaged aortic heart valve improves patient outcomes

The more frequently a hospital performs a minimally invasive technique called transcatheter aortic valve replacement, or TAVR, to replace a damaged aortic heart valve, the better patients fare, on average, immediately after the procedure, researchers reported at the American College of Cardiology's 65th Annual Scientific Session.

Study: Age and gender affects prevalence of certain peripheral vascular diseases

New findings from large-scale studies of more than 3.6 million people who underwent screening for cardiovascular disease reveals that a person's age and gender affects the prevalence of certain types of peripheral vascular diseases (PVD), and that diabetes is a major risk factor for developing these diseases, even in patients without heart disease.

Patients undergoing mini-MVR have similar outcomes compared with conventional surgery

Patients undergoing minimally invasive mitral valve repair or replacement (mini-MVR) have similar outcomes as patients undergoing conventional surgery and also experience shorter hospital stays and fewer blood transfusions, according to an article posted online today by The Annals of Thoracic Surgery.

St. Luke’s surgeon first in world to implant Medtronic’s new, MRI-compatible neurostimulator system

Steven Falowski, MD, Chief of Functional Neurosurgery at St. Luke’s University Health Network in Bethlehem, Pennsylvania today was the first surgeon in the world to implant Medtronic’s brand new, full-body, MRI-compatible paddle electrode leads for the Restore neurostimulator system.

Edwards Lifesciences' SAPIEN 3 transcatheter heart valve approved in Japan

Edwards Lifesciences Corporation, the global leader in patient-focused innovations for structural heart disease and critical care monitoring, today announced that the Japanese Ministry of Health, Labor and Welfare approved the Edwards SAPIEN 3 transcatheter heart valve for the treatment of patients suffering from severe, symptomatic aortic stenosis.

Carotid stenting noninferior to surgery for asymptomatic patients

The findings of the ACT 1 trial suggest that carotid artery stenting is just as effective as carotid endarterectomy in patients with asymptomatic stenosis.

Vascular surgery safer than stenting for older patients with carotid stenosis

Vascular surgery appears to be safer than stenting for patients over 70 years of age with carotid stenosis, or a blockage of the carotid arteries in the neck, according to new findings published today in the Lancet.

Best management unclear for patients needing carotid revascularisation

Research highlights the vulnerability of patients with symptomatic carotid stenosis to stroke while awaiting revascularisation.

SIMnext introduces DR Doppler Dynamic Ultrasonography Training System

Health care professionals now have a new way of accessing ultrasound training in a mobile and affordable manner using the DR Doppler Dynamic Ultrasonography Training System (DR Doppler), a training tool from SIMnext, LLC, a medical simulation research and development company based in Peoria, Ill.

New, personalized approach to detecting low back pain

Scientists at The Feinstein Institute for Medical Research have discovered a new, personalized approach to diagnosing low back pain. The findings from a clinical study show that serum levels of the proinflammatory cytokine interleukin-6 (IL-6) vary in individuals with lumbar intervertebral disc disease and that biochemical profiling of circulating cytokines may assist in refining personalized diagnoses of disc diseases.

Scientists develop a method for cell replacement in diseased vessels

In industrialized countries, a particularly high number of people suffer from arteriosclerosis -- with fatal consequences: Deposits in the arteries lead to strokes and heart attacks. A team of researchers under the leadership of the University of Bonn has now developed a method for guiding replacement cells to diseased vascular segments using nanoparticles.

Arterial grafts provide better outcomes than venous grafts in heart bypass surgery patients

The Society of Thoracic Surgeons has released new clinical practice guidelines that recommend expanding the use of arteries from the chest and forearm rather than using veins from the leg when performing coronary artery bypass grafting (CABG) surgery in certain patients. The guidelines, posted online today, will appear in the February 2016 issue of The Annals of Thoracic Surgery.

Small-vessel disease has uncertain impact on large-vessel stenosis outcomes

Research shows that small-vessel disease is common among patients with intracranial arterial stenosis, but that its effect on stroke risk cannot be separated from the effect of associated risk factors.

Ultrasound can help identify patients at increased risk of future stroke

Ultrasound, a non-invasive technique commonly used to study the presence of atherosclerosis disease in blood vessels, can be used to identify patients at increased risk of future stroke who could benefit from surgery. Since surgical treatment to prevent stroke is only considered beneficial to some, ultrasound can prove useful in preventing unnecessary surgical intervention, new research at Umeå University in Sweden shows.

Arterial imaging with 3-D MRI could help to determine stroke risk among diabetics

People with diabetes may be harboring advanced vascular disease that could increase their risk of stroke, according to new research being presented next week at the annual meeting of the Radiological Society of North America.

MCG researchers explore how neurofibromatosis puts young patients at risk for cardiovascular disease

It's a fairly common genetic condition that can surface as a series of dark skin spots and result in a host of maladies from tumors to premature cardiovascular disease. Medical College of Georgia researchers hope their studies of how neurofibromatosis 1, or NF1, can dangerously thicken or thin blood vessel walls will one day help physicians better identify and treat these young patients at cardiovascular risk.

New treatment may help patients with chronic renovascular disease

A new treatment may help patients with a chronic kidney condition that can also lead to heart problems and premature death, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN).
