Interatrial septal aneurysm (IASA) and patent foramen ovale (PFO)-either alone or coexisting-are a frequent cause of cryptogenic cerebral and/or peripheral thromboemboli. The IASA plus PFO combination has been shown to confer higher risk, particularly in adults aged 45 years or younger. Therefore, recognition and documentation of these 2 abnormalities during an echocardiographic (transthoracic or transesophageal) study, when performed for other indications, is essential.
GLASGOW, Scotland -- Putting stroke patients to work keeps them from deteriorating, found investigators in a meta-analysis.
AMSTERDAM -- Treatment regimens for type 2 diabetes that include pioglitazone (Actos) were associated with lower risk of stroke and myocardial infarction, claimed investigators for the drug's maker.
Ischemic infarcts of the brain are usually caused by vascular disease, but 1 in 5 results from emboli that arise in the heart. The largest contributor to cardioembolic stroke is non-valvular atrial fibrillation, which is associated with a 5-fold increased risk of cerebral infarction.
AMSTERDAM -- Mixed results from trials investigating the clinical efficacy of idraparinux, an investigational long-acting factor X inhibitor, suggest the drug is not as effective as standard therapy for treatment of pulmonary embolism.
VIENNA, Sept. 4 -- Even normotensive patients with diabetes can reduce their risk of heart attack, stroke, and renal failure by lowering of blood pressure, researchers reported here.
ROME -- Stroke survivors who discontinued statin therapy within a year of hospital discharge almost tripled their mortality risk, investigators here reported.
SANTIAGO DE COMPOSTELA, Spain -- Ischemic stroke patients already taking statins should be continued on the drugs during the acute phase, clinicians here recommended.
BOSTON -- Antioxidant vitamins C and E and beta carotene did not reduce the risk of cardiovascular events in more than 8,000 high-risk women, reported researchers here.
NEW YORK -- Increasing brain activity is the key to improving eyesight by visual training for stroke patients with hemianopia, researchers here found.
BALTIMORE --Women who have migraine with visual symptoms have a 50% greater risk of ischemic stroke than women without the headaches, researchers reported.
BIRMINGHAM, England -- Warfarin's stroke prevention benefits extend to the elderly -- without increasing the risk of major bleeds.
BIRMINGHAM, England -- When seeking to reduce the risk of stroke in older patients by screening for atrial fibrillation, a pulse-based system is an effective approach, found researchers here.
The authors describe a case of air embolism that developed during a plane flight in a woman who had a congenital cystic adenomatoid malformation. They review the pathophysiological mechanisms, risk factors, clinical features, and treatment of air embolism.
DUISBURG, Germany -- Multidetector CT angiography can diagnose and assess intracranial aneurysms with equivalent accuracy to digital subtraction angiography, investigators here reported.
ROCHESTER, Minn. -- Patients with nonvalvular atrial fibrillation have about a 33% lower risk of stroke and major vascular events when treated with oral anticoagulants rather than antiplatelet therapy, findings from a systematic review of clinical trials suggest.
SAN ANTONIO -- Patients who had post-stroke urinary incontinence and were unaware of the urge to void had a significantly higher risk of mortality and nursing-home placement.
SAN ANTONIO -- Drugs that lower angiotensin II may increase the risk of stroke, contrary to conventional wisdom, an investigator asserted here.
SAN ANTONIO -- Years before carotid artery disease poses a stroke risk, arterial thickening and early-stage atherosclerosis may cause deterioration in cognitive performance.
SAN ANTONIO -- Mild impairment of the executive function domain of cognition may represent an early marker of an increased stroke risk, according to data from the Framingham Study.
BOSTON -- The FDA has okayed use of a strap-on robotic arm to help restore function to an upper-extremity disabled by a stroke, according to the manufacturer.
MORGANTOWN, W.Va. -- Operators who staff hospital healthlines are often unable to recognize the symptoms of a stroke, investigators here found.
abstract: Idiopathic pulmonary fibrosis (IPF) is a chronic interstitial lung disease of unknown etiology that leads to progressive fibrosis and respiratory failure. Patients with IPF typically present in their sixth to seventh decade of life with the insidious onset of progressive dyspnea and cough. Lung histopathology reveals the distinct lesion of usual interstitial pneumonia (UIP), and other causes of UIP, such as collagen-vascular disease, drug exposure, or occupational exposures, must be excluded. A confident clinical diagnosis of IPF can often be made without resorting to surgical lung biopsy if certain clinical features are present and a typical pattern is identified on high-resolution CT (HRCT) scanning of the thorax. Changes on HRCT scans that are typical for UIP include a predilection for peripheral and basilar lung zones with patchy involvement and sparing of more central areas, especially in upper lung zones.

* Vena caval interruption has been used in the treatment of deep venous thrombosis (DVT) to prevent PE since the early 1970s. Filter placement has been increasing in the past decade. We estimate that filters are placed in more than 0.2% of all Medicare recipients annually.
Lp(a) is a fascinating variant of low-density lipoprotein (LDL). It is basically an LDL molecule that has been modified by the covalent addition of apoprotein(a). Elevated levels of Lp(a) correlate with increased risk of acute coronary syndromes, cerebrovascular accident, peripheral arterial disease, and coronary mortality. This Q&A session answers some curiosities about Lipoprotein(a).
