Hospitals can improve patient care and reduce costs associated with coronary angioplasty if cardiologists perform more of these procedures through an artery in the wrist and if they take steps to discharge such patients on the same day, according to a new study led by Washington University School of Medicine in St. Louis. Coronary angioplasty […]

Discovery of Atherosclerosis as “Alzheimer’s disease” of Blood Vessels
Researchers at Washington University have discovered a novel phenomenon that takes place during the formation of atherosclerosis, or the progressive buildup of plaques in artery walls. As we age and our bodies are continuously exposed to damaging agents such as high cholesterol and high blood pressure, the inner walls of the arteries begin to accumulate […]
Washington People: Angela L. Brown
Angela L. Brown, MD, grew up on her family’s farm in southern Arkansas.

Watching her grandparents persevere through the demands of farm life, and her parents balance their careers — […]
Dietary Nitrate Increases Muscle Speed and Power in Patients with Heart Failure
Washington University researchers have demonstrated that beetroot juice, which is rich in nitrate (NO3), can increase muscle function in heart failure patients. This may enhance their ability to perform activities of daily living and hence improve their quality of life. Although heart failure starts out as a disease of the heart, it ultimately becomes a […]
Genetic Study Identifies Individuals Who Benefit Most From Statins
Researchers at Washington University have shown that a panel of genetic markers can identify individuals at increased risk for heart attack. Those same individuals appear to benefit most from statin therapy (read more). The research appears online March 5th in the Lancet. For patients at risk of heart disease, doctors routinely prescribe statins, known for […]
Multiple Rare Gene Mutations Associated With Increased Risk of Heart Attack
Research performed at Washington University and other leading biomedical research institutions found that multiple rare mutations in two genes increase an individual’s risk of heart attack. The research appears online this week in the journal Nature. Nathan Stitziel, MD, PhD, a cardiologist at Washington University School of Medicine and co-first author of the report, helped […]
New Treatment For Marfan’s Syndrome Shows Promise
An investigational treatment for Marfan’s syndrome is as effective as the standard therapy at slowing enlargment of the aorta, new research shows (read more). The findings indicate a second treatment option for Marfan’s patients, who are at high risk of sudden death from aortic dissection. “For years, standard medical therapy for Marfan’s syndrome consisted of […]
Gene Mutations in NPC1L1, the Target of the Drug Ezetimibe, Found to Reduce Cholesterol and Protect Against Heart Attack
Researchers at Washington University have shown that mutations in the gene NPC1L1 are associated with lower cholesterol and about 50% reduction in risk of heart attack. The research was led by Washington University Cardiologist Dr. Nathan Stitziel and appears online November 12th in the New England Journal of Medicine. Ezetimibe, a drug commonly prescribed to […]
The Heart’s Own Immune Cells Can Help It Heal
Researchers at Washington University have found the heart holds its own pool of immune cells capable of helping it heal after injury, according to a new study in mice at Washington University School of Medicine in St Louis. Research led by cardiologist Dr. Kory Levine, showed that the injured pediatric and adult heart contains two […]
New Experimental Drug Reduces Tissue Damage Following Myocardial Infarction and Minimizes the Risk of Bleeding
Researchers at Washington University and St. Louis based APT Therapeutics Inc., show that a novel drug known as APT102 significantly reduced tissue damage to heart muscle following experimental myocardial infarction and minimized the risk of bleeding during follow-up treatments. The research team at Washington University was led by Dr. Dana Abendschein. Myocardial infarction causes damage […]
Regions of the Genome Once Mislabled as ‘Junk’ are Linked to Pathogenesis of Heart Failure
Dr. Jeanne Nerbonne and a team of Washington University researchers from the Center of Cardiovascular Research (CCR) reported results from a comprehensive analysis of different families of RNA molecules expressed in the human heart. The researchers studied non-failing hearts and failing hearts before and after patients received mechanical pump support from left ventricular assist devices […]
Nanoparticles Treat Muscular Dystrophy in Mice
A team of researchers at Washington University School of Medicine in St. Louis have demonstrated a new approach to treating muscular dystrophy. (Read more) Mice with a form of this muscle weakening disease showed improved strength and heart function when treated with nanoparticles loaded with rapamycin, an immunosuppressive drug recently found to improve recycling of […]
New Insights Into How Immune Cells Heal Injured Hearts
The immune system plays an important role in the heart’s response to injury. But until recently, conflicting data made it difficult to distinguish the immune factors that encourage the heart to heal following a heart attack, versus those factors that can lead to further damage. (Read more) Now, research performed by Dr. Slava Epelman and […]

Over-Use of Drug-Eluting Stents Found
A review of more than 1.5 million percutaneous coronary intervention (PCI) procedures documented in the National Cardiovascular Data Registry has found that cardiologists are “routinely over-using” drug-eluting stents versus bare-metal stents for patients at low risk for repeat blockages of arteries. The study, published online in the Archives of Internal Medicine found that DES use […]
Noninvasive Imaging Technique May Help Kids with Heart Transplants
Washington University cardiologists have developed a noninvasive imaging technique that may help determine whether children who have had heart transplants are showing early signs of rejection. The technique could reduce the need for these patients to undergo invasive imaging tests every one to two years. The noninvasive technique, which involves the use of gadolinium contrast-enhanced […]
