Targeting CPR education in high-risk neighborhoods could increase the number of bystanders giving CPR and decrease deaths from cardiac arrest, according to a new American Heart Association scientific statement published in its journal Circulation. http://medicalxpress.com/news/2013-02-cpr-high-risk-neighborhoods.html Cardiology Mon, 25 Feb 2013 16:00:05 EST news281009763 Patients with mitral regurgitation, a type of valvular heart disease common in the elderly, are living longer after surgery, Yale School of Medicine researchers report in the journal Circulation: Cardiovascular Quality and Outcomes. http://medicalxpress.com/news/2012-05-survival-mitral-valve-heart-surgery.html Cardiology Thu, 10 May 2012 11:03:48 EST news255866613 Inheriting gene variants that increase the risk of developing coronary heart disease does not necessarily mean an individual is going to have reduced life expectancy if he or she suffers a heart attack. http://medicalxpress.com/news/2012-05-news-heart-patients.html Cardiology Tue, 01 May 2012 09:28:04 EST news255083182 In the largest multicenter clinical trial of children undergoing early-stage surgery for single-ventricle heart defects, differences in intraoperative management did not significantly affect neurodevelopmental outcomes at 14 months of age. Instead, the strongest influences were innate patient characteristics and general medical morbidity during the child's first year of life. http://medicalxpress.com/news/2012-04-children-born-severe-heart-defect.html Cardiology Thu, 05 Apr 2012 12:48:31 EST news252848862 People who have a cardiac arrest that can't be helped by a defibrillator shock are more likely to survive if given CPR based on updated guidelines that emphasize chest compressions, according to research reported in the American Heart Association journal, Circulation. http://medicalxpress.com/news/2012-04-guidelines-based-cpr-non-shockable-cardiac-victims.html Cardiology Mon, 02 Apr 2012 16:00:08 EST news252586216 An estimated 1.6 million Americans suffer moderate to severe leakage through their tricuspid valves, which are complex structures that allow blood to flow from the heart's upper right chamber to the ventricle. If left untreated, severe leakage can affect an individual's quality of life and can even lead to death. http://medicalxpress.com/news/2012-01-non-invasive-tricuspid-valve-anatomy-severity.html Cardiology Wed, 18 Jan 2012 10:57:12 EST news246106599 How sildenafil, the active ingredient in Viagra, can alleviate heart problems is reported by Bochum's researchers in cooperation with colleagues from the Mayo Clinic in Rochester (Minnesota) in the journal Circulation. They studied dogs with diastolic heart failure, a condition in which the heart chamber does not sufficiently fill with blood. The scientists showed that sildenafil makes stiffened cardiac walls more elastic again. The drug activates an enzyme that causes the giant protein titin in the myocardial cells to relax. "We have developed a therapy in an animal model that, for the first time, also raises hopes for the successful treatment of patients" says Prof. Dr. Wolfgang Linke of the RUB Institute of Physiology. http://medicalxpress.com/news/2011-12-viagra-heart-failure-mechanism.html Cardiology Fri, 23 Dec 2011 10:03:30 EST news243857003 Researchers at the Cardiac & Vascular Institute at NYU Langone Medical Center have identified a hidden culprit in the battle against women's heart disease. Plaque disruption, a rupture or ulceration of cholesterol plaque in a coronary artery, has been discovered as the mechanism behind myocardial infarction (heart attack) in some women without significant coronary artery disease (CAD) - that is, open rather than closed arteries on an angiogram. The study is published in the September 27th issue of the journal Circulation. http://medicalxpress.com/news/2011-09-hidden-heart-culprit-women.html Cardiology Mon, 26 Sep 2011 16:00:05 EST news236267424 A study published today in the journal Circulation showed that a cardiac magnetic resonance (CMR) scan is as accurate as an angiogram in diagnosing the causes of heart failure in patients with dilated cardiomyopathy. The scan causes less pain and discomfort and is also more cost-effective. http://medicalxpress.com/news/2011-09-heart-scan-angiogram-patients.html Cardiology Thu, 08 Sep 2011 10:20:01 EST news234694277 High blood pressure could be caused by a common virus, according to a study carried out by a team of Chinese doctors which could lead to better treatment for millions of people around the world. http://medicalxpress.com/news/2011-08-virus-high-blood-pressure-chinese.html Diseases, Conditions, Syndromes Mon, 15 Aug 2011 04:50:31 EST news232602618 (Medical Xpress) -- An analysis of heart disease and stroke statistics collected in 192 countries by the World Health Organization (WHO) shows that the relative burden of the two diseases varies widely from country to country and is closely linked to national income, according to researchers at the University of California, San Francisco (UCSF). http://medicalxpress.com/news/2011-07-heart-disease-tied-national-income.html Health Fri, 08 Jul 2011 11:02:06 EST news229341705 Researchers at Mount Sinai School of Medicine have found in a Phase II trial that a gene therapy developed at Mount Sinai stabilized or improved cardiac function in people with severe heart failure. Patients receiving a high dose of the therapy, called SERCA2a, experienced substantial clinical benefit and significantly reduced cardiovascular hospitalizations, addressing a critical unmet need in this population. The data are published online in the June 27 issue of the American Heart Association journal Circulation. http://medicalxpress.com/news/2011-06-gene-therapy-heart-failure.html Cardiology Tue, 28 Jun 2011 16:27:34 EST news228497233 The most lethal and sudden cardiovascular event can be the toughest for doctors to diagnose. http://medicalxpress.com/news/2011-05-simple-bedside-screening-effectively-patients.html Cardiology Mon, 16 May 2011 03:25:13 EST news224734540
