Vascular & Endovascular

This channel includes news on non-coronary vascular disease and therapies. These include peripheral artery disease (PAD), abdominal and thoracic aortic aneurysm (AAA and TAA), aortic dissection, pulmonary embolism (PE), critical limb ischemia (CLI), carotid artery and stroke interventions, venous interventions, deep vein thrombosis (DVT), and interventional radiology therapies. The focus on most of these therapies is minimally invasive, catheter-based procedures performed in a cath lab.

JACC: Female PAD patients lose mobility, function faster than men

Women suffering from lower extremity peripheral arterial disease (PAD) had greater mobility loss and faster functional decline compared with men with the same condition. Researchers attributed these differences to smaller baseline calf muscle areas in female PAD patients, according to a study in the Feb. 8 Journal of the American College of Cardiology.

ISC: Less than one-third of stroke patients receive timely thrombolysis

Less than one-third of acute stroke patients treated with intravenous tissue plasminogen activator (tPA) receive the thrombolytic drug within 60 minutes of their hospital arrival, according to research presented at the American Stroke Association's International Stroke Conference (ISC) 2011 in Los Angeles. The research is simultaneously published Feb. 10 in Circulation.

ISC: Ischemic strokes rise among teens & children, fall among middle-aged

The number of acute ischemic stroke hospitalizations among middle-aged and older men and women fell between 1994 and 2007, but sharply increased among those under age 35--including teens and children--according to research presented at the American Stroke Association's International Stroke Conference 2011 in Los Angeles.

ISC: Stroke patients increasingly not taking meds, despite Part D coverage

Cost-related nonadherence continues to rise, particularly among stroke survivors aged 45 to 54 years or uninsured. Medicare beneficiaries with Part D coverage also have a higher risk of cost-related nonadherence and could possibly be the culprit of early Part D adopters, according to data presented at the 2011 American Heart Association/American Stroke Association's International Stroke Conference in Los Angeles today.

AIM: Hospitals that spend more have fewer inpatient deaths

Hospitals that spend more have lower inpatient mortality for six common medical conditions, including acute MI, congestive heart failure and acute stroke, based on the results of a retrospective study published Feb. 1 in the Annals of Internal Medicine.

JAMA: Can individualized treatment help prevent stroke death?

Patients who had an ischemic stroke and were admitted to hospitals designated as primary stroke centers had a modestly lower risk of death at 30 days, compared to patients who were admitted to non-designated hospitals, according to a study in the Jan. 26 issue of the Journal of the American Medical Association.

Covidien releases updated peripheral stent in EU

Covidien has made available its EverFlex+ self-expanding peripheral stent system in Europe.

New stroke guidelines: Better data reporting can improve stroke center care

Providing a framework for which metrics should be collected at comprehensive stroke centers can help with quality improvement and reduce stroke related events and improve patient care, according to new American Heart Association/American Stroke Association guidelines published online Jan. 13 in Stroke.
