It’s important to know about the causes of unrecognized, or silent, heart attacks and how to prevent them.
Among patients with a first episode of pulmonary embolism (the obstruction of the pulmonary artery or a branch of it leading to the lungs by a blood clot) who received 6 months of anticoagulant treatment, an additional 18 months of treatment with warfarin reduced the risk of additional blood clots and major bleeding, however, the benefit was not maintained after discontinuation of anticoagulation therapy, according to a study in the July 7 issue of JAMA.
A stroke happens in an instant. And many who survive one report that their brain never works like it once did. But new research shows that these problems with memory and thinking ability keep getting worse for years afterward – and happen faster than normal brain aging.

An estimated 65 percent of ischemic stroke survivors experience cognitive impairment and decline. However, little is known about the varying roles of cognitive risk and protective factors before, during and after stroke.
Researchers have long had reason to hope that blocking the flow of calcium into the mitochondria of heart and brain cells could be one way to prevent damage caused by heart attacks and strokes. But in a study of mice engineered to lack a key calcium channel in their heart cells, Johns Hopkins scientists appear to have cast a shadow of doubt on that theory. A report on their study is published online this week in Proceedings of the National Academy of Sciences.
Common extra heartbeats known as premature ventricular contractions (PVCs) may be a modifiable risk factor for congestive heart failure (CHF) and death, according to researchers at UC San Francisco.

MedStar Heart & Vascular Institute at MedStar Washington Hospital Center was the first hospital in the Washington metropolitan region to implant the newly approved WATCHMAN™ Device. The new device is designed to prevent stroke in high-risk patients with atrial fibrillation who are seeking an alternative to blood-thinning medication. Blood thinners are effective in reducing the risk of stroke for patients with A-fib, but many cannot tolerate these medications because of the risk of bleeding. The WATCHMAN device, which resembles a tiny umbrella, is used to close off a pouch on the left side of the heart, which is believed to be the source of the majority of stroke-causing blood clots.
New devices called stent retrievers are enabling physicians to stop strokes in their tracks. For the first time, new guidelines from the American Heart Association/American Stroke Association recommend the treatment for certain stroke patients.
While heart disease is the number one cause of death in both sexes, it poses special considerations in women—with risks often beginning in childhood and changing at different stages of life. Insights on cardiovascular disease (CVD) risk in women and girls throughout the life span are shared in a special symposium feature in the June issue of The American Journal of Medical Sciences (AJMS). The official journal of the Southern Society for Clinical Investigation (SSCI), AJMS is published by Wolters Kluwer.
Other topics include neurology, obesity, statins, and the risks of wearing high heels.
New research shows that cardiovascular disease conditions trigger pathways that protect the blood vessels. The response may be a new therapeutic strategy for cardiovascular disease. This research is highlighted as one of this month’s “best of the best” as part of the American Physiological Society’s APSselect program.
In the first randomized trial to look at statin effects on behavior, researchers at the University of California, San Diego School of Medicine report that aggressive behavior typically declined among men placed on statins (compared to placebo), but typically increased among women placed on statins.
A 44-year-old woman has received a successful heart transplant at Ronald Reagan UCLA Medical Center, thanks to an experimental Total Artificial Heart designed for smaller patients. The UCLA patient is the first person in California to receive the smaller Total Artificial Heart, and the first patient in the world with the device to be bridged to a successful heart transplant.
UCLA doctors used a 3-D model of a patient’s heart to guide a tricky minimally-invasive valve replacement. UCLA patient Richard Whitaker was not a candidate for traditional surgery due his heart's unique anatomy and previous surgeries. Doctors practiced with the 3-D heart model before the actual procedure to make sure the valve would fit, which it did! Richard is now back to work after having the procedure and looking forward to planning a trip to Europe.
A University of Michigan Health System study reveals enzyme CD39 is capable of clearing the atherosclerotic plaque that leads to so many heart attacks and strokes.
Eating a healthy diet was linked with a lower risk of dying from heart disease, stroke, cancer or other diseases among a population of low-income individuals living in the Southeastern U.S., according to research led by Vanderbilt University investigators. Nearly two-thirds of the participants in the study were African-American.

Future therapies for failing hearts are likely to include stem-like cells and associated growth factors that regenerate heart muscle. Scientists have just taken an important step towards that future by identifying a stem-like “progenitor” cell that produces only heart muscle cells.
Working with heart muscle cells from diabetic rats, scientists at Johns Hopkins have located what they say is the epicenter of mischief wreaked by too much blood sugar and used a sugar-gobbling enzyme to restore normal function in the glucose-damaged cells of animal heart muscles.
In what may be a major leap forward in the quest for new treatments of the most common form of cardiovascular disease, scientists at Johns Hopkins report they have found a way to halt and reverse the progression of atherosclerosis in rodents by loading microscopic nanoparticles with a chemical that restores the animals’ ability to properly handle cholesterol.
Heart attack patients age 65 and older who have reduced heart function might still benefit from implanted defibrillators, according to a Duke Medicine study published in the Journal of the American Medical Association. But fewer than 1 in 10 eligible patients actually get a defibrillator within a year of their heart attacks, the study found.

Patients with moderate heart failure now have a new option to help manage their chronic disease and reduce their chance of being readmitted to the hospital.
Now research conducted in fruit flies, rats and monkeys by scientists at Johns Hopkins, UC San Diego, and other institutions reveals that levels of a protein called vinculin increase with age to alter the shape and performance of cardiac muscle cells — a healthy adaptive change that helps sustain heart muscle vitality over many decades.
Despite the intense activity and high hopes that surround the use of stem cells to reverse heart disease, scientists still face multiple roadblocks before the treatment will be ready for clinical prime time. Researchers are now finding ways to maximize the healing potential of stem cells by helping them overcome the inhospitable conditions of a damaged heart – bringing the promise of stem cell therapy for heart disease one step closer to reality.
For healing the heart after a heart attack, stem cell therapies show promise but are slow to implement. Researchers develop a new treatment called microsphere therapy that can be kept on-hand and administered more readily than stem cells.
