Researchers at the University of Illinois at Chicago College of Medicine will study gender differences in how the heart uses and stores fat—its main energy source—and how changes in fat metabolism play a role in heart disease, under a new $2 million, 4-year grant from the National Heart, Lung and Blood Institute. http://medicalxpress.com/news/2013-05-men-women-hearts-fuel-differently.html Medical research Tue, 21 May 2013 08:30:02 EST news288341701 (Medical Xpress)—A groundbreaking technique developed at the University of Virginia School of Medicine is allowing scientists to examine histone modifications of genetic loci – a process that regulates gene expression – in single cells. The researchers believe the new method will have broad applications for most biomedical areas, most immediately in atherosclerosis research. http://medicalxpress.com/news/2013-01-discovery-unprecedented-gene.html Medical research Fri, 25 Jan 2013 06:35:19 EST news278318097 (Medical Xpress)—Growing new blood vessels in the lab is a tough challenge, but a Johns Hopkins engineering team has solved a major stumbling block: how to prod stem cells to become two different types of tissue that are needed to build tiny networks of veins and arteries. http://medicalxpress.com/news/2012-12-stem-cells-blocks-blood-vessels.html Cardiology Thu, 20 Dec 2012 15:45:42 EST news275240732 UT Southwestern Medical Center researchers have pinpointed a molecular mechanism needed to unleash the heart's ability to regenerate, a critical step toward developing eventual therapies for damage suffered following a heart attack. http://medicalxpress.com/news/2012-12-key-gene-regenerating-cells-heart.html Medical research Thu, 20 Dec 2012 10:37:59 EST news275222211 Scientists at the Gladstone Institutes have revealed the precise order and timing of hundreds of genetic "switches" required to construct a fully functional heart from embryonic heart cells—providing new clues into the genetic basis for some forms of congenital heart disease. http://medicalxpress.com/news/2012-09-scientists-genomic-blueprint-heart.html Medical research Thu, 13 Sep 2012 12:46:15 EST news266759167 A promising new drug target for the treatment and prevention of heart failure has been discovered by researchers at Mount Sinai School of Medicine in New York, NY, US.

Both approaches, Professor Jan Nilsson told delegates at the Frontiers in CardioVascular Biology (FCVB) 2012 meeting, can be considered truly ground breaking since for the first time they target the underlying cause of CVD. The FCVB meeting, organised by the Council on Basic Cardiovascular Science (CBCS) of the European Society of Cardiology (ESC), held 30 March to 1 April at the South Kensington Campus of Imperial College in London. http://medicalxpress.com/news/2012-03-immune-therapies-frontier-atherosclerosis.html Cardiology Fri, 30 Mar 2012 09:47:23 EST news252319633 Standing up more often may reduce your chances of dying within three years, even if you are already physically active, a study of more than 200,000 people published in Archives of Internal Medicine today shows. http://medicalxpress.com/news/2012-03-evidence-prolonged.html Health Mon, 26 Mar 2012 16:00:10 EST news251984133 Researchers at the Intermountain Medical Center Heart Institute have, for the first time ever, made a connection between tiny genetic molecules called microRNAs and the imminent threat of a heart attack, according to a new study. http://medicalxpress.com/news/2012-03-first-ever-link-tiny-genetic-imminent.html Cardiology Sun, 25 Mar 2012 15:30:01 EST news251904285 Researchers from Queen Mary, University of London and the University of Surrey have found a protein inside blood vessels with an ability to protect the body from substances which cause cardiovascular disease. http://medicalxpress.com/news/2012-03-protein-discovery-cardiovascular-disease.html Cardiology Sun, 11 Mar 2012 19:00:01 EST news250687373 Atrial Fibrillation patients who are prescribed the powerful blood thinner warfarin often take it with vitamins or supplements that can hamper its effectiveness, or skip doses completely, increasing their risk for stroke, according to new research. http://medicalxpress.com/news/2011-11-heart-patients-vitamins-medication.html Cardiology Mon, 14 Nov 2011 17:33:08 EST news240514381 (Medical Xpress) -- A new study published in the Journal of the American College of Cardiology reports that higher natural levels of testosterone in elderly men may reduce their risk of a heart attack or stroke. http://medicalxpress.com/news/2011-10-high-testosterone-heart-tied.html Cardiology Thu, 06 Oct 2011 11:41:06 EST news237120048 Newly discovered subtle markers of heart damage hidden in plain sight among hours of EKG recordings could help doctors identify which heart attack patients are at high risk of dying soon. http://medicalxpress.com/news/2011-09-ekg-anomalies-heart-fatal.html Cardiology Wed, 28 Sep 2011 14:00:06 EST news236432792 Researchers at Mount Sinai School of Medicine have identified a new drug target that may treat and/or prevent heart failure. The team evaluated failing human and pig hearts and discovered that SUMO1, a so-called "chaperone" protein that regulates the activity of key transporter genes, was decreased in failing hearts. When the researchers injected SUMO1 into these hearts via gene therapy, cardiac function was significantly improved. This research indicates that SUMO1 may play a critical role in the pathogenesis of heart failure. The data are published online in Nature. http://medicalxpress.com/news/2011-09-heart-failure.html Cardiology Wed, 07 Sep 2011 13:00:10 EST news234618984 A scientist at the Gladstone Institutes has discovered how gene regulation can make hearts beat out of sync, offering new hope for the millions who suffer from a potentially fatal heart condition. http://medicalxpress.com/news/2011-08-scientist-genetic-factor-implicated-heartbeat.html Medical research Mon, 08 Aug 2011 15:20:01 EST news232035365 A one-dose method for delivering gene therapy into an arterial wall effectively protects the artery from developing atherosclerosis despite ongoing high blood cholesterol.
