Transvenous lead extraction in low volume centre linked to doubled risk of death

Cardiac lead extraction is safer in high volume centres, according to the largest study of contemporary practice in Europe published today in European Heart Journal. Extraction in a low volume centre was associated with a doubled risk of death while in hospital.

Scientists identify molecule that could be targeted to prevent vision loss in diabetics and preterm infants

Researchers at Bascom Palmer Eye Institute, part of the University of Miami Miller School of Medicine, have identified a new molecule that induces the formation of abnormal blood vessels in the eyes of diabetic mice.

WPI researchers grow beating human heart cells on spinach leaves

Researchers face a fundamental challenge as they seek to scale up human tissue regeneration from small lab samples to full-size tissues, bones, even whole organs to implant in people to treat disease or traumatic injuries: how to establish a vascular system that delivers blood deep into the developing tissue.

Changes in the vascular system could play role in initiating Alzheimer’s disease

As the average age of Americans increases, so too does the problem of Alzheimer's, one of the world's most common neurological diseases. In recent years, scientists have explored many new approaches to clear the plaques and tangles in the brain that characterize the condition, but the new drugs have largely turned out to be disappointing.

Chemists develop biosafe luminescent nanoparticles for imaging tumors and blood vessels

Chemists from Russia and Switzerland created biosafe luminescent nanoparticles for imaging tumors and blood vessels damaged by heart attack or stroke.

Shortage of low blood pressure drug for patients with septic shock linked to elevated risk of death

Patients with septic shock admitted to hospitals affected by the 2011 shortage of the drug norepinephrine had a higher risk of in-hospital death, according to a study published online by JAMA.

New stenting tool found to be less painful and cheaper than current methods

A new tool for assessing the narrowing of the heart's arteries was found to be as effective as current methods and less painful for patients.

Simple fix could eliminate unnecessary coronary stenting procedures

Physician researchers at Thomas Jefferson University suspect that some cases of coronary artery spasm go unrecognized and are incorrectly treated with stents.

Medications, PCI equally beneficial for treating complete blockage in heart's arteries

In patients with a complete blockage in the heart's arteries that persists over time, treatment with medications alone was found to be equal to percutaneous coronary intervention (PCI), a procedure to open blocked arteries, in terms of major adverse events over three years, according to a study presented at the American College of Cardiology's 66th Annual Scientific Session.

Study reveals link between endovascular procedures and microbleeding in the brain

Small leakages from blood vessels in the brain, known as microbleeds, increase with age and are associated with cognitive decline. Of 84 older patients undergoing transcatheter aortic valve replacement (TAVR), nearly a quarter developed new microbleeds after their procedure, according to results of a single-center study presented at the American College of Cardiology's 66th Annual Scientific Session.

New iFR technique for assessing clogged arteries reduces discomfort and adverse events

For patients experiencing angina (chest pain) or a heart attack, a new tool called instantaneous wave-free ratio (iFR) was equivalent to the currently-preferred tool, fractional flow reserve (FFR), in terms of incidence of major adverse events according to two studies presented at the American College of Cardiology's 66th Annual Scientific Session. The studies also showed iFR resulted in markedly less patient discomfort and reduced procedure-related adverse events compared to FFR.

Milli-robots powered by MRI could provide targeted minimally invasive treatment

Invasive surgical techniques - cutting through the breastbone for open heart surgery or making a large incision to inspect an abdominal tumor - allow physicians to effectively treat disease but can lead to sometimes serious complications and dramatically slow healing for the patient.
