Carotid bypass surgery doesn't help cognitive performance after stroke Surgery to bypass a blocked carotid artery in order to restore adequate blood flow to the brain does not improve cognitive performance in patients who've had a stroke or mini-stroke (TIA), according to research presented at the American Stroke Association's International Stroke Conference 2013. http://medicalxpress.com/news/2013-02-carotid-bypass-surgery-doesnt-cognitive.html Cardiology Mon, 11 Feb 2013 07:10:05 EST news279786759 Lower cuff pressure reduces wound complications in TKA (HealthDay)—Lower tourniquet cuff pressure, achieved using a limb-occlusion pressure method, is associated with reduced postoperative wound complications after total knee arthroplasty, according to research published in the Dec. 19 issue of The Journal of Bone & Joint Surgery. http://medicalxpress.com/news/2013-01-cuff-pressure-wound-complications-tka.html Surgery Mon, 14 Jan 2013 14:40:01 EST news277390690 Young scientist helps identify cause of widespread eye disease Branch retinal vein occlusion – blockage of the blood vessels that channel blood from the retina – is a common eye disease. A type of blood clot in the eye, the disease causes reduced vision, and people with the disease also typically have an increased risk of hypertension, diabetes and other serious conditions. A young scientist from the University of Copenhagen has made a significant contribution to finding the cause of the disease. http://medicalxpress.com/news/2012-12-young-scientist-widespread-eye-disease.html Ophthalmology Fri, 21 Dec 2012 02:54:41 EST news275280853 Coronary angioplasty improves cardiac arrest survival Coronary angioplasty improves survival in all patients with out of hospital cardiac arrest, according to research presented at the Acute Cardiac Care Congress 2012.

While viral illnesses with wheezing in infancy predicted wheezing later in childhood, this association was due in part to decreased neonatal lung function. http://medicalxpress.com/news/2012-05-viral-infections-infancy-wheezing-symptoms.html Diseases, Conditions, Syndromes Wed, 23 May 2012 09:50:00 EST news256985384 Solution does not reduce rate of progression to development of heart attack after chest pain Patients experiencing symptoms such as chest pain who received from paramedics an intravenous solution consisting of glucose-insulin-potassium (GIK) had no reduction in the rate of progression to heart attack and no improvement in 30-day survival, although GIK was associated with a lower rate of the composite outcome of cardiac arrest or in-hospital death, according to a study appearing in JAMA. The study is being published early online to coincide with its presentation at the American College of Cardiology's annual scientific sessions. http://medicalxpress.com/news/2012-03-solution-heart-chest-pain.html Cardiology Tue, 27 Mar 2012 10:20:01 EST news252061137 Coronary artery spasms rare during dobutamine stress echo (HealthDay) -- The occurrence of coronary artery spasm (CAS) during dobutamine stress echocardiography (DSE) is rare, with a prevalence of 0.4 percent, according to a study published in the March 15 issue of The American Journal of Cardiology. http://medicalxpress.com/news/2012-03-coronary-artery-spasms-rare-dobutamine.html Cardiology Fri, 09 Mar 2012 14:50:01 EST news250517916 Severity of heart attack is dependent on the time of day The size of a heart attack and subsequent left-ventricular function are significantly different based on the time of day onset of ischemia, according to a first of its kind study in humans, published online Nov. 17 in Circulation Research.

The team of Massimiliano Mazzone demonstrates that blocking the protein PhD2 in white blood cells accelerates the maturation of blood vessels. This leads to a better blood perfusion to organs that had been deprived from blood supply by ischemia. This might become a new therapeutic approach in ischemic diseases. http://medicalxpress.com/news/2011-10-strategy-blood-vessel-maturation-therapeutic.html Medical research Tue, 11 Oct 2011 11:46:15 EST news237552369 Fast track to vascular disease In Western societies, atherosclerosis of the arteries is one of the leading causes of death. Chronic, localized inflammation of the blood vessel wall facilitates the growth of fibrous plaques, which leads to narrowing or occlusion of the vessel, and thereby promotes heart attacks and stroke. The persistence of the inflammatory reaction is due to a loss of control over the activity of the immune system. http://medicalxpress.com/news/2011-06-fast-track-vascular-disease.html Medical research Fri, 03 Jun 2011 10:59:16 EST news226317515
