    New Microwave Helmet Can Help Diagnose Strokes

    Posted by jadef on Jun 24, 2014 11:35:24 AM

    Swedish scientists from the Chalmers University of Technology, Sahlgrenska Academy, and Sahlgrenska University Hospital, have created a helmet that can quickly determine whether a patient has suffered a stroke and can determine if a clot or leaky vessel was the cause.

    Join Million Hearts™ in the Fight Against Heart Attacks

    Posted by Jennifer Sharp on Feb 10, 2014 7:49:36 AM

    The Department of Health and Human Services (HHS) continues its national initiative aimed to prevent 1 million heart attacks and strokes in the U.S. over the next five years. The campaign is called Million Hearts and is co-led by CDC and the Center for Medicare and Medicaid Services (CMS), integrating and amplifying a range of existing heart disease and stroke prevention programs, policies, and activities.

    Perioperative Statin Therapy Reduces Perioperative Cardiac Events and Hospital Length of Stay

    Posted by Joseph Esherick on Aug 28, 2012 9:47:52 AM

    Perioperative statin therapy has long been felt to confer cardiac protection during both cardiac surgery and major noncardiac surgery.  Until recently the data have been scarce to definitively make claims in support of this belief.  In 2004, Durazzo et al. conducted the first randomized trial examining the use of Perioperative statins in major noncardiac surgery.  They compared the use of atorvastatin 20 mg daily compared against placebo initiated 2 weeks prior to elective major vascular surgery and continued for 45 days post-operatively.  The investigators found that statins were associated with a 70% relative risk reduction of the combined end-point of death, nonfatal MI, unstable angina, or stroke. [1] Prior to this in 1999, Christenson had demonstrated cardioprotective effects of statins during coronary artery bypass grafting surgery. [2]

    Statins are thought to be beneficial for a myriad reasons:

    • They lower lipids and have additional pleiotropic effects.
    • The cardioprotective effects of statins during the perioperative period is more likely related to their pleiotropic effects than their lipid-lowering effects.
    • Statins inhibit the action of HMG-CoA Reductase which is the rate-limiting step in cholesterol synthesis, but effective lipid lowering takes months.
    • Perioperative studies have demonstrated that statins confer a cardioprotective benefit when started even 1-2 weeks in advance of major surgery.
    • These pleiotropic effects of statins include suppression of endothelial nitric oxide which promotes coronary vasodilation.
    • Statins also reduce lipopolysaccharide-induced tissue factor release, decrease plasminogen activator inhibitor levels, and increase tissue plasminogen activator; the combination of which reduces coronary thrombosis.
    • Statins also have anti-inflammatory properties which may provide more plaque stability. [3]
